Student loan forecasts for England
Published
Background
Income Contingent Repayment (ICR) student loans are provided by Government to higher education students and some further education students to cover course fees and living costs while they are studying. They were first introduced in the UK for new undergraduate students in 1998, at the same time as tuition fees. Prior to 1998, university students were provided funding by Government through a mixture of grants and, from 1990, mortgage style loans that were available to help with living costs. Mortgage style loans are not covered in this publication.
Each of the four constituent countries of the UK now have their own student loan policies, but only English student loans are considered in this publication. These are loans issued to English domiciled students that attend any learning provider in the UK and EU domiciled students that attend learning providers in England. A summary timeline of income contingent repayment loans is available in Table 2.1 below.

Student loans are issued by and administered by the Student Loans Company (SLC) on behalf of the Government and the devolved administrations in the UK. The Department for Education produces forecasts for its outlay on, and the repayments it expects to receive from, the English student loans that it is responsible for. These are for use in financial planning, policy development and to value the loans that have been issued in its annual accounts. The forecasts presented in this publication are produced by four models, as follows:
Student entrants model – this model forecasts the number of full-time undergraduate entrants eligible for tuition fee loans in England. These forecasts are used in the student loan outlay and repayment models to estimate the future growth in full-time loan borrower numbers.
Student loan outlay model – this model produces forecasts for loan outlay on higher education ICR loans, including those issued to undergraduates and postgraduate students.
Student loan earnings model – this model produces forecasts for the future earnings of higher education ICR loan borrowers.
Student loan repayments model – this model produces forecasts for the future repayments that will be made by higher education ICR loan borrowers.
Advanced Learner Loans model – this model produces forecasts for loan outlay and repayments that will be made on Advanced Learner Loans, which are available for some further education courses.
This document provides information on these four models, including the methodology, data sources and assumptions used in producing the forecasts.
These forecasts are based on announced government policy, as of 11th June 2022. Any changes to student loan eligibility, loan amounts, or terms and conditions, if implemented by Government, could affect the forecasts presented in this publication.
DfE’s higher education (HE) student entrants model forecasts the number of full-time undergraduate England-domiciled student entrants to UK providers and EU-domiciled student entrants to providers in England. These are all student entrants, whether eligible for a student loan or not. A subset of these student entrants is then forecast as the population eligible for tuition fee loans from Student Finance England (SFE). The model assumes a constant proportion of loan-eligible entrants based on the latest estimated proportion of loan-eligible entrants in HESA’s Core Student Record (2020/21). Growth rates for loan-eligible entrants are then applied to the latest year of outturn SLC data in the student loans outlay model (2020/21), which inform the department’s financial accounts regarding student loan outlay via SFE. The forecasts are also used by the Office for Budget Responsibility (OBR) in the Office for Budget Responsibility – Economic and Fiscal Outlook, March 2022 which forecasts public spending, including student finance over a five-year period.
Scope
The forecasts are based on full-time undergraduate entrants to the following provider types:
Higher education institutions (HEIs)
Designated Alternative Providers (APs) registered with the Office for Students (OfS) as an Approved (fee cap) providers,
HEIs in the devolved administrations.
These providers capture the vast majority of HE full-time undergraduate student entrants to Approved (fee cap) providers eligible to charge the maximum annual tuition fee loans of £9,250. Of the remaining Approved (fee cap) providers, Further Education Colleges (FECs) and non-designated APs are excluded. Fee-loan eligible students at these providers are captured within DfE’s higher education student loans outlay model. Since Access and Participation Plans (APP) and Teaching Excellence Framework (TEF) awards also impact the maximum fees providers can charge under each OfS registration category, the forecast does not include all providers that could charge maximum fees and may also include some providers that cannot.
The following students are excluded from the student entrants forecast:
Full-time undergraduate England- and EU-domiciled entrants at the following providers in England: that have not registered with the OfS, Approved and former non-designated APs and FECs registered as Approved (fee cap).
England-domiciled full-time undergraduate student entrants to APs and FECs in the devolved administrations.
EU-domiciled full-time undergraduate student entrants to all providers in the devolved administrations.
Non-England UK domiciled students full-time undergraduate student entrants.
Continuing full-time undergraduate students – of any domicile to any providers.
Part-time undergraduates (levels 4 to 6) – of any domicile to any providers.
Postgraduates (level 7 and 8) – of any domicile to any providers.
Non-EU overseas students – of any levels and modes of study.
Entrants from groups 1, 2, 5-7 who are eligible for tuition fee loans from SFE are captured within DfE’s higher education student loans outlay model.
Methodology
The student entrants model forecasts the following entrants over a six-year period, in three distinct modelling stages:
England-domiciled student entrants
EU-domiciled student entrants
Loan-eligible entrants.
The model uses the following data:
ONS population estimates in England inclusive to 2020
England-domiciled student entrants are forecast by age and gender. In general a regression model is used to forecast entrants (exceptions are detailed in the relevant sections). At a high level, England-domiciled entrants are calculated as:
There are some minor exceptions to this method for some age groups depending on the data that’s available, and these are discussed below. Overall, the model calculates four volumes: population, applicants, acceptances, and entrants. Entrants are calculated over two stages:
Core entrants are modelled based on the interaction between population projections, applicant rates and acceptance rates (i.e. provider behaviour).
Additional groups of entrants that are calculated independently as a result of:
Department for Health & Social Care's (DHSC) policy of an additional 50,000 nurses by 2025 (a component of which will encompass new full-time undergraduate nursing student entrants)
The inclusion of entrants to former designated APs registered as Approved (fee cap) into the population of the forecast.

Population
ONS population estimates and projections for males and females are aggregated by age groups 18, 19, 20 and 21-25 to provide yearly population estimates and projections for England. These estimates and projections are used as the base population for each model of these age groups, under the assumption that population data for England are a suitable proxy for the England-domiciled student population. Population data are not used in the models for age 17 and under and 26 and above.
Main scheme applicants
Main scheme applications refer to those submitted prior to the UCAS June deadline and do not include non-main scheme routes such as clearing. UCAS main scheme applicant statistical releases are aggregated by gender and age groups 17 and under, 18, 19, 20, 21-25 and 26 and above. For age groups 17 and under and 26 and above, these data are used as the base population (not population estimates and projections).
For each historic academic year, the model calculates the proportion the historic proportion that have applied by the January deadline compared to the June where we get the total number of main scheme applicants. A three-year average of the growth in this proportion is applied to estimate the January proportion of total main scheme applications of the current application cycle (2022/21). From this, total applicants are calculated.
Applicants aged 17 and under are forecast by applying a three-year average of applicants to all forecast years. Applicants of all other age groups are forecast using a linear regression model on log-transformed values. For applicants aged 18-25, these values are applicant rates (defined as applicants divided by population), from which, applicants are forecast for each academic year by multiplying population by the forecast applicant rate. For applicants aged 26 and above, these values are applicant numbers.
The historic time-series used in the regression for age groups 18 to 20 begins in 2014, and for age group 21-25 begins in 2013. The start year is different for the different age groups so that the data included in the time-series are more reflective of recent applicant trends. The academic year 2021/22 has been removed from the time-series for all age groups except 18-year-olds. This is because application growth was exceptionally high in this year due to the uncertainty caused by coronavirus causing this data point to be inconsistent with historic trends and expectations for future trends. It hasn’t been removed for 18-year-olds because we are expecting strong growth in 18-year-old-applicants over the forecast.
Accepted applicants
UCAS end of cycle report of acceptances is separated by acceptance type (main scheme and non-main scheme) and are aggregated by gender and age groups 17, 18, 19, 20 and 21 and above. This means that applicants aged 21-25 and 26 and above are combined for the remainder of the model.
Main scheme accepted applicants aged 17 and under are forecast by applying a three-year average of main scheme accepted applicants to all forecast years. Main scheme accepted applicants of all other age groups are forecast using a linear regression model on a log-transformed acceptance rate (defined as main scheme accepted applicants divided by applicants), from which main scheme accepted applicants are forecast for each academic year by multiplying applicants by the forecast acceptance rate.
The historic time-series used in the regression for age all groups is 2016/17 – 2019/20. Some earlier data points have been removed because they show a trend that we are no longer seeing in recent years, and 2020/21 – 2021/22 have been removed because these years are impacted by coronavirus and thus aren’t representative of what we would expect in future years.
For all age groups, the model calculates the historic main scheme and non-main scheme proportions of total accepted applicants and applies the proportions from the latest year of historic data (2021/22) to all forecast years to forecast non-main scheme accepted applicants. Total accepted applicants are the sum of main scheme and non-main scheme acceptance applicants (per year).
Tables 3.2 and 3.3 set out the 18-year-old population against applicants and acceptances (for 18-year-olds and all ages). 18-year-olds make up approximately 50% of total entrants, so trends in that population are key to understanding trends in applicants (and therefore accepted applicants).

Entrants
HESA entrants are aggregated by the same groups as accepted applicants and include both first degree and other undergraduate (levels 4, 5 and 6).
Entrants aged 17 and under are forecast by applying a three-year average of entrants to all forecast years. Entry rates of all other age groups are forecast by applying a three-year average of growth in entry rate (defined as entrants divided by total accepted applicants) as constant to each forecast year, from which entrants are forecast by multiplying accepted applicants by entry rate. The use of a three-year average over a linear regression for this element of the model is a legacy function and is reviewed periodically as part of the model’s development.
A manual update is applied in 2021/22 to revise the forecast annual percentage growth with what is seen monthly payment data provided by SLC.
Office for Students (OfS) registration
Since 2019/20, providers in England (offering higher education courses) that desire designated status have been required to register with the OfS under one of two categories: Approved (fee cap) or Approved.
The student entrants model includes the impact of former designated APs registered as Approved (fee cap) as of 13th June 2022. This means that any former designated APs that have since registered, or are yet to register, as Approved (fee cap) have not been included. The forecast does not include students of non-designated APs registered as Approved (fee cap) as very little is known about the number of students at these providers. Therefore, this is not the total potential impact of entrants to Approved (fee cap) providers.
To estimate these entrants, the model relies on the OfS register (as of 13th June 2022) and matches Approved (fee cap) providers to HESA’s AP Student Record 2020/21 to calculate a baseline number of England-domiciled full-time undergraduate student entrants. Forecast student entrant growth rates are then applied to the baseline to forecast these entrants. It is therefore assumed that entrants to these providers will grow at the same rate to HEIs. As the number of entrants to these providers remains much smaller than HEIs, this assumption is believed to have little impact on the total growth in student entrants.
This method does not assume any future changes in registration behaviour, though it is likely that more designated APs will register as Approved (fee cap). However, it is not yet known which providers will and any estimation of which would be purely judgment based. Given that the number of entrants currently estimated in the impact is small (around 18,000 per year), there is little risk in not assuming changes in registration behaviour, as changes will likely be small as more providers continue to register. This estimate is updated periodically as more providers register.
Loan borrowers to Approved providers are captured within DfE’s higher education student loans outlay model.
Budget 2020 policy: 50,000 nurses
An additional group of student entrants are forecast as part of the Government’s Budget 2020 policy of an additional 50,000 nurses. The forecast number are based on a joint DHSC-DfE costing of the policy and accounts for a level of displacement for students already forecast, as well as new entrants to the system (who would have ordinarily not entered).
EU-domiciled student entrants model
EU-domiciled entrants to providers in England are forecast as a total (i.e., not by age and gender) since numbers in this group are low.
Applications
UCAS data are only available for applications (not applicants) for EU-domiciled applicants. Applications are estimated for the current application cycle (where only January deadline data is available) but are not forecast beyond this. The model calculates the historic proportion of applications by the January deadline compared to the June total of main scheme applications. A three-year average of the growth in this proportion is applied to estimate the January proportion of total main scheme applications of the current application cycle (2022/23). From this, total main scheme applications are calculated.
Accepted applicants
UCAS accepted applicant data is only available for total accepted applicants for EU-domiciles, meaning main scheme and non-main scheme are combined. Total accepted applicants are forecast for the latest year of outturn data that are available across the model (i.e., the cycle year which UCAS applications are estimated for, currently 2022/23) but are not forecast beyond this. To forecast acceptance rate, a three-year average of historic acceptance rate growth (2019/20 to 2021/22) is applied to the latest year of data across the model (2022/23), from which accepted applicants are forecast by multiplying applications by the forecast acceptance rate.
Entrants
A three-year average entry rate (2018/19 to 2020/21) is multiplied by accepted applicants to forecast entrants in 2020/21. From 2022/23, entrant numbers are assumed to be flat at -24% of the 2021/22 estimate. This is as a result of and reflects the removal of EU student finance and is validated by recent UCAS data on 2022/23 applicants by the January deadline.
Loan-eligible entrants
England-domiciled loan-eligible entrants are forecast by applying as constant the latest outturn proportion of loan-eligible entrants in HESA’s Core Student Record (for this publication, 2020/21). As a constant proportion of student entrants, these loan-eligible entrants forecast the same annual growth rates.
The removal of student finance for EU nationals from 2021/22 (except for a small number of groups) means that EU-domiciled student entrants are expected to grow at a different rate to loan-eligible entrants. Estimates of growth in EU-domiciled loan-eligible entrants are based on analysis of outturn SLC 2020/21 data that identifies the proportion of loan borrowers that would be eligible each year under Citizens’ Rights or as one of the remaining eligible groups (not required to be eligible under Citizens’ Rights). This proportion is applied to the 2021/22 loan-eligible forecast to estimate annual growth rates thereafter.
Nursing, midwifery and allied health profession (AHP)
Loan-eligible entrants to nursing, midwifery and AHP courses are forecast separately from the wider population as they are expected to grow at a higher rate, with specific Government policies aimed at increasing the uptake of these courses.
A 2018/19 baseline number of nursing, midwifery and AHP loan-eligible entrants are derived based on HESA’s Core Student Record. Against which, Department of Health and Social Care (DHSC) forecast growth rates are applied, which reflect the expected growth of these courses relative to increased applicant demand, the 50k nurses policy aimed at increasing uptake, as well as capacity for funded clinical places.
EU-domiciled nursing, midwifery and AHP loan-eligible entrants are not forecast from 2021/22 as the number of these entrants is expected to be minimal.
Long-term forecasts
Beyond the six-year forecasting period, loan-eligible entrant growth rates are forecast in a long-term model (to 2102) as an input for the student loans repayment model. This model projects growth rates for loan-eligible entrants only. This specifically includes undergraduate (both full-time and part-time), Master’s and Doctoral students.
In the long-term model, growth rates beyond the six-year period are calculated by weighting ONS principal population projections by age frequencies derived from SLC data for undergraduates and HESA data for postgraduates. The sum of annual male and female population projections per age are calculated and compared against the reference year 2025 to derive annual population growth for each age. Age weights are then used to find the weighted cumulative average population growth per study type. This is then converted to year-on-year change for forecasting growth rates and numbers beyond the six-year forecast period for each student population.
Data quality
The nature of any forecast is inherently uncertain and dependent on the quality of the source data, modelling methodology and assumptions made throughout. The model uses published data from ONS, UCAS and HESA to forecast full-time undergraduate entrants.
ONS Population Estimates and Projections
ONS population projections are on a calendar year basis. The model forecasts all subsequent components on an academic year basis (August to July). Although this misalignment may slightly impact applicant rates, it is assumed that ONS population projections are accurate enough for these purposes as the majority of full-time undergraduate entrants will commence study in the first calendar year of the academic year (matching the population data).
ONS publish data quality guidance on national population projections, which are the main population forecast used by Government. Short-term principal projections are largely considered reliable; given that the student entrants model only forecasts over a six-year period, this increases confidence in the base population which forecast entrant are modelled from. ONS do not make any predictions of future political or economic changes that could affect population numbers.
Post-2012/13 higher education data
Due to the 2012/13 tuition fee reform to fees of £9,000 per year, the model only uses data from 2013/14 onwards to inform the forecast. The lack of data points means that the model is sensitive to any significant anomalies to the trends in these data, which increases the level of uncertainty in the forecasts, particularly due to the complexity of the higher education environment (caused by HE policy and funding changes, as well as Covid).
Assumptions
It is uncertain how both student and provider behaviour will adapt over the next few years. Such as how providers will respond to the substantial increase seen in 2021/22 applicants, or whether more of the population will apply to higher education to upskill or retrain a result of the economic impacts of Covid-19, both of which will affect the model’s applicant and acceptance rates.
Additionally, students may withdraw from a course after accepting their place but before enrolling with the provider. The model assumes no changes in the proportions of applicants that have accepted a place withdrawing prior to entering a provider, although this could change in future.
Entrants where gender is classified as ‘Other’ are combined with female entrants because females account for the largest group of entrants. This assumption requires review, particularly with an increase in non-binary gender identification, but it has been applied for this publication as a legacy assumption with minimal impact to the forecast.
EU
EU domiciled entrant forecasts are particularly uncertain because:
UCAS applicant statistical releases are included as applications. A single UCAS applicant can make up to five applications per academic year, and the average number of applications can vary over time, causing increased uncertainty over EU domicile forecasts. Given this constraint, the model assumes that EU applications are a suitable proxy for EU applicants for forecasting EU entrants.
The forecast for EU-domiciled entrants has been assumed constant from 2022/23 onwards without information on how much further EU entrants will fall after a 52% reduction in 2021/22. Future EU-applicant behaviour is particularly uncertain given the UK’s withdrawal from the European Union.
Model performance
The forecast population changed for 2018/19 from HEFCE (Higher Education Funding Council for England) fundable entrants to the SFE tuition fee loan-eligible population. As a result, it is only comparable to compare forecasts against outturn from the 2018/19 academic year (thus excluding the first in this series of publications).
Outturn is based on analysis of HESA's Student Record filtered for full-time (all) undergraduate first year students, by domicile (and country of HE provider as England for EU student entrants). 2018/19 outturn data are the same as those published in HESA's ‘HE student enrolments over time' table from the source data 051 record only (as the population of the forecast for 2018/19 was HEIs only). However, from 2019/20 additional analysis of HESA's Student Record was required to identify full-time (all) undergraduate first year student entrants to former designated APs registered as Approved (fee cap). The 2019/20 and 2020/21 outturn are a subset of the total student entrants published in HESA's ‘HE student enrolments over time’ table (based on all source data).
The model has under-estimated entrants in the three academic years for which forecasts can be compared against outturn. This could reside in forecast total main scheme applicants, accepted applicants or entry rates, as at the point of publication, the model relies on data from the UCAS January deadline to forecast entrants for the upcoming academic year. Due to a declining 18-year-old population in 2018, 2019 and 2020 such growth in entrants was not anticipated.

With only three years of outturn data to compare to, it is difficult to determine whether the difference is random, the impact of temporary factors or due to weaknesses in methodology. We will continue to review and if this underestimation proves to be a consistent feature, then we will look at options to address this through the model’s methodology.
The student loan outlay model forecasts loan amounts that the Department for Education (DfE) expects to pay higher education students (and their providers) via the Student Loans Company (SLC).
A range of sub-models are used to capture the various loan types available to students on higher education courses. The loan products that outlay forecasts are produced for are:
Full-time undergraduate loans (Plan 2) – the loan system for students on full-time courses that started since September 2012 that are eligible for undergraduate student support funding, consisting of fee loans and maintenance loans.
Part-time undergraduate loans (Plan 2) – the loan system for students on part-time courses that are eligible for undergraduate student support funding. These first became available in September 2012, consisting of a tuition fee loan. From August 2018, maintenance loans were also available to some part-time students.
Full-time undergraduate loans (Plan 5) – the loan system for students on full-time courses that start in or after 1st August 2023 and are eligible for undergraduate student support funding, consisting of fee loans and maintenance loans.
Part-time undergraduate loans (Plan 5) – the loan system for students on part-time courses that start in or after 1st August 2023 and are eligible for undergraduate student support funding, consisting of fee loans and maintenance loans for some part-time students.
Postgraduate Master’s loans (Plan 3) – loans available to Master’s students to help cover fees and living costs. They were introduced in August 2016 and are on the Plan 3 repayment system.
Postgraduate Doctoral loans (Plan 3) – loans available to Doctoral students from August 2018 to help cover fees and living costs. They are on the Plan 3 repayment system.
Outlay forecasts for Plan 1 loans are no longer produced due to the very small number of recipients expected in 2021/22, because most students who started a course before September 2012 have now completed those studies. The Student Loans Company recorded less than £450,000 of Plan 1 loan outlay in the tax year 2021-22.
Eligible English domiciled students are entitled to fee and maintenance loans for courses that are eligible for undergraduate funding. Eligible EU domiciled students are entitled to fee loans only. Both are entitled to the same amount for postgraduate loans.
Full-time and part-time undergraduate loans
Since 2019/20, English institutions offering higher education courses have been required to register with the Office for Students (OfS) under one of two categories: Approved (fee cap), or Approved. The maximum fees institutions registered as Approved (fee cap) are permitted to charge depends on whether they have a Teaching Excellence and Student Outcomes Framework (TEF) rating and whether they have an Access and Participation Plan (APP) that has been approved by the OfS. Currently, Approved (fee cap) providers can charge a higher fee amount if they have an approved APP: up to £9,250 with and £9,000 without a TEF award, for full-time students. Approved (fee cap) providers can only charge a basic fee amount if they do not have an approved APP: up to £6,165 with and £6,000 without a TEF award, for full-time students. Providers in the Approved category are not subject to fee limits, but students attending these institutions are only eligible for student support up to the basic fee cap of Approved (fee cap) institutions.
Maintenance loans for eligible students depend on their location and household income (where a borrower applies for a means tested loan). The maximum maintenance loan for full-time Plan 2 borrowers living away from home and studying outside of London, in 2021/22 is £9,488. Table 1A of the Student Loans Company statistical publication Student support for Higher Education in England presents the maximum rates of maintenance loans and tuition fee loans for full-time students domiciled in England.
Maintenance loans became available in 2018/19 to part-time, on-campus, degree students. These loans mirror the full-time maintenance loan, with the intensity of study taken into account alongside means testing and location. Students studying courses at less than 25% intensity are not eligible for part-time maintenance loans.
As part of a wider reform of higher education system, the Government is consulting on the introduction of Lifelong Loan Entitlement, Higher Technical Qualifications and piloting higher technical short courses. As the consultation is still ongoing ta the time of writing, these policy changes are not included in the forecasts presented.
Postgraduate Master’s loans
The postgraduate Master’s loan was introduced in 2016/17. Eligibility for a Master’s loan depends on the duration and intensity of the student’s course, their age on the first day of the first academic year of their course, and their nationality or residency status. The course must also be provided by a university or college in the UK, which is either publicly funded or a designated private provider. From 2019/20, English providers are required to register with the OfS as Approved (fee cap) or Approved to be eligible for student support funding.
Unlike undergraduate loans, Master’s loan entitlement for eligible students depends on the start date of their course, rather than location or household income. The maximum Master’s loan amount for a course starting in 2021/22 is £11,570 across the length of the course.
Postgraduate Doctoral loans
The postgraduate Doctoral loan was introduced in 2018/19. Eligibility for a Doctoral loan is based on the duration of the student’s course, their age on the first day of the first academic year of their course, and their nationality or residency status. The course must also be provided by a university or college in the UK, which is either publicly funded or a designated private provider. From 2019/20, English providers are required to register with the OfS as Approved (fee cap) or Approved to be eligible for student support funding.
Doctoral loan entitlement for eligible students depends on the start date of their course. The maximum Doctoral loan amount in 2021/22 is £27,265 across the length of the course.
Methodology
Student loan outlay, for undergraduate higher education loan products (and including postgraduate Initial Teacher Training, which is also funded under Plan 2), is forecast based on historical data from the Student Loans Company. For postgraduate loan products, where historical information is limited, an alternative forecasting method is required.
Undergraduate higher education loan products
The student loan outlay forecasts for higher education loan products that are eligible for Plan 2 or Plan 5 Higher Education funding use current and historical anonymised data on individual loan borrowers from the Student Loans Company. Individual-level data on loan borrowers were provided by SLC in April 2021 providing nearly complete information on student loans up to and including 2020/21. Using this and other information from SLC and growth rates from the student entrants model, forecast students were generated and allocated loans according to announced loan caps or OBR RPIX (Retail Price Index All Items Excl Mortgage Interest) forecasts. Note that fee and maintenance loan levels available to students are typically already known for the first two or three academic years for which the model produces forecasts, currently 2021/22 and 2022/23. Maximum fee amounts in 2021/22, 2022/23, 2023/24 and 2024/25 have been set at the same levels as in 2017/18, while maintenance loan entitlements were increased in line with the latest Office for Budget Responsibility (OBR) RPIX central forecast for the Jan-Mar quarter in each year.
This modelling method assumes that the distribution of characteristics of future loan borrowers, such as means-testing, gender and degree subject, is the same as for loan borrowers from the recent past. Internal analysis of historic trends indicates that this assumption is sound based on recent SLC data. Changes to student finance being brought in from 2023/24 may impact on the distribution of the characteristics of loan borrowers and on their loan amounts in the short-term. This is being monitored by DfE, and if needed, or where future policies are announced, an assessment will be made on the impact of the policy on the borrower numbers and loan amounts and the forecasts may be adjusted accordingly.
When the individual-level data was received from SLC in April 2021, it contained nearly complete data for 2020/21. To use this most recent year of data for modelling, estimates of the missing information until the end of the academic year, from April to August 2021, were made and the dataset amended accordingly. There are three main types of missing information between April and August, and these were quantified to produce a mini forecast of a full year of data for 2020/21. These three types of information are:
Missing borrowers. By April, most loan borrowers in the academic year have been paid a loan amount by SLC. However, some students may not yet appear in the dataset because their first loan payment is late in the year, for example if their course starts between April and August, or if a student’s circumstances change and they require student finance when they did not earlier in the year. Borrowers can apply for funding up to 9 months after starting and later applications can also be honoured by SLC, so borrower numbers can change after the end of the academic year. The number of missing borrowers was calculated using SLC data on the total number of students at the end of August 2021, split by institution type, study mode, student domicile, and loan product. To account for late reporting after the end of the academic year, the number of August borrowers was uplifted by the growth in the number of enrolled borrowers in 2019/20 from the SLC August 2020 to the SLC April 2021 individual-level data, split by study mode, domicile, and for England-domiciled full-time students, by institution type too. For each combination of characteristics, this uplifted figure was compared to the number of students in the individual-level SLC April 2021 data, and a number of students equal to the difference in the April and uplifted August totals was added to the individual-level dataset by randomly sampling and duplicating pre-existing entrants and amending the unique identifiers of the duplicated records. It was assumed that all missing borrowers after April 2020/21 were entrants (first year students).
Missing withdrawals. Some students will withdraw from university between April and August of an academic year, and this information will not have been contained in the April 2021 extract for 2020/21. In addition, there is a (non-negligible) time lag between a student’s withdrawal and the HE provider notifying SLC of that event, so some information on withdrawals up to end April 2021 is missing too. To calculate the number of extra withdrawals in 2020/21, the 2021 extract was compared with the 2020 extract, with the 2021 extract providing an updated view on withdrawals in 2019/20; concretely, the proportion of missing withdrawals by study mode, institution type and loan product received was estimated. Within each of these combinations of characteristics, the expected number of extra withdrawals in 2020/21 was then randomly sampled and their records amended to add withdrawal information.
Missing loan outlay. Most loan outlay is paid prior to April in each academic year and is therefore recorded in the April cut of the SLC data. However, students who start later in the academic year, or whose circumstances change, may receive loan payments later than April and not all borrowers are paid their requested loan amount. An evaluation of the payments against the requested amount in 2019/20 (i.e. the most recent full academic year of data in the 2021 extract) is made to estimate the proportion of borrowers that will not get paid their requested amount after April; these proportions are calculated by study mode, institution type and loan product. For each of these combinations of characteristics, the April SLC data was searched for students who had received less than their requested loan amounts and had not withdrawn in 2020/21. A random sample of these students had their loan amounts increased to their requested amounts, based on the aforementioned proportions.
Once this missing 2020/21 data had been imputed, the now-full year of data was carried forward into the model.
For borrowers who have not finished their course yet, their original course length is not always representative of the number of years of loans a borrower will go on to receive. For example, a borrower may repeat a year, switch courses to include or remove a placement year, transfer onto a new course entirely (starting in year 1 again) or withdraw. To reflect this in the outlay forecasts, once the full year of 2020/21 data had been imputed, continuation rates reflecting average course lengths were applied to the latest and previous cohorts of students who were studying in 2020/21. These continuation rates were derived from 2014/15 and 2015/16 HESA student record data for full-time students, whereas for part-time students the continuation rates are based on 2016/17 and 2017/18 aggregate SLC data on part-time students taking up tuition fee loans. This adjustment was applied randomly within each study mode and for each original course length.
This data could now be used to generate students starting in future academic years. Entrant borrowers in 2020/21 were sampled, duplicated and renamed with new date information to generate entrants in future years up to 2026/27. Entrant borrowers from 2023/24 onwards are all Plan 5 borrowers, while all previous entrants are Plan 2. The number of students that needed to be generated in each future year was calculated by applying the student entrants forecast growth rates to the number of 2020/21 entrants from aggregate SLC data. Different growth rates are calculated for part and full-time students and England and EU domiciled students, so the new students were generated for each combination of these characteristics. Some subsections of the student population were separated out and generated using a set entrants forecast, for example where a student numbers cap was in place. These sets of students included Nursing, Midwifery and Allied Health (NMAH) students, students studying Medicine and Dentistry, postgraduate Initial Teacher Training students, and students studying at alternative providers. These students were identified by a combination of JACS (Joint Academic Coding System) 3.0 code, course level and text mining course names. A small portion of each number forecast was set aside to generate students studying two or more funded courses.
Some students may be eligible to receive funding for more than one HE Plan 2 or Plan 5 course; examples include postgraduate teacher training students, students completing a foundation degree before continuing to study for a bachelors-level degree, or students studying an Equivalent or Lower Qualification (ELQ)-exempt course. Students studying more than one funded course therefore usually already have a loan balance when they start their second course. The entrants generated by the method above did not have pre-existing loan balances. In order to generate a realistic loan borrower population where some entrants each year already have a loan from a previous course, a random sample (by study mode and domicile) of previous loan borrowers were chosen and allocated to start new courses, with the proportion starting at different institution types, course levels and subjects (NMAH, Medicine and Dentistry, Initial Teacher Training, and all other courses) determined by an analysis of historic SLC data.
At this point in the modelling process, the SLC data consisted of a row per student per course with their loan outlay recorded up to the end of 2020/21 (some of which is estimated), as well as future students generated from current and previous students, and renamed and with their date information shifted forwards. With this data, future outlay can be generated.
To generate future outlay, the outlay of each student in the most recent year (2020/21) was uprated by the OBR forecast of RPIX or to the relevant loan cap, whichever was lower; for full-time students that started prior to 2020/21 and were identified to be on a year overseas or a placement year, their outlay in 2019/20 was used as a basis for generating future outlay. Separate tuition fee caps were applied to students at Approved and Approved (fee cap) providers, set to the maximum loan amount for each type of institution. Maintenance loan caps were applied separately to medical and dentistry students in their fifth and sixth years (who are eligible for lower loans because they receive an NHS bursary in these years), and to all other students. Additionally, a random sample of students on courses of length 4 years were chosen to be sandwich placement students and were given lower fee and maintenance loans in their third years, where their third year was later than 2020/21. A random sample of entrants starting in 2020/21 who had fee loans below the cap in that year were chosen to be studying courses with fee waiver students, and allocated fee loans at the cap in their second year, even where this was an above-inflation increase. From 2021/22, a random sample of nurses was chosen to take out a reduced maintenance loan as a result of the re-introduction of NHS bursaries for NMAH students. The proportions of students who have sandwich placement, fee waiver or nursing bursary loan adjustments were determined by an analysis of SLC data or by agreement with the OBR.
The academic year loan outlay forecasts were converted into financial years. This was done based on an analysis of academic year payments and which financial year they fall in, using SLC data. This analysis took into account at which point within an academic year a student started. Each academic year straddles two financial years, and students starting later in an academic year will have a larger portion of their loan paid in the second financial year. At this point, forecasts of total loan outlay as well as a breakdown by Plan type were produced.
Master’s loans
Master’s loans were introduced in 2016/17, but reliable, historic Master’s loan borrower data is available at an aggregate level only. Given the differences in the loan products, with the Masters’ loans entitlement for the course rather than each year, the method for forecasting future loan outlay uses a different approach to undergraduate loans. Instead, estimates of the total number of entrants who are likely to take up a loan each academic year are derived by assuming that the number of England- and EU- domiciled loan recipient entrants in 2020/21, based on SLC data, grows annually by the rates displayed in Table 4.1.
The Covid-19 pandemic led to a 25% increase in Master’s loan-recipient entrants in 2020/21. Based on start of June 2022 SLC payment data, we estimate a decrease of 11% in England-domiciled loan-recipient entrants in 2021/22.This represents an expectation that the pandemic-related growth in Master’s take-up has only been a single year shock, and growth has since returned to pre-pandemic trends. From 2022/23, we assume that England-domiciled loan-recipient entrants grow at a constant rate of 2.5%, which is the average of the growth rates from 2013/14 to 2015/16 and 2017/18 to 2019/20 of HESA taught and research Master’s entrants. As student finance support is discontinued from 2021/22 for most EU nationals, we estimate a significant drop in EU-domiciled loan recipient entrant numbers from 2021/22 onwards.

Annual academic year loan outlay is calculated using a cohort approach, based on start year and the proportion of students within each course duration. Our model parameters are shown in Table 4.2, where average loan amounts are rounded to the nearest £100. The parameters are derived from SLC management information data for the 2016/17 borrowers; in the 2020 publication, the proportions of loan recipient entrants were updated to bring the 2018-19 model forecast closer to outturn and they have been kept the same this year. The expected number of loan borrowers in each cohort is multiplied by a corresponding average loan amount and uprated by OBR forecast RPIX for entrants only, in each year. The sum of the outlay from each cohort is aggregated to produce a final academic year outlay figure. Financial year outlay is then calculated using the assumption that two thirds of the yearly loan amount each academic year is given in the first financial year it overlaps with (covering loan outlay from August to March), and the remaining third in the following financial year (covering April to July).
Doctoral loans
Doctoral loans were introduced in academic year 2018/19, but reliable, historic Doctoral loan borrower data is available at an aggregate level only. To qualify for a Doctoral loan, the borrower's course must last between 3 and 8 academic years. For each course duration, estimates of the total number of student entrants who are likely to take up a loan each academic year are calculated by assuming that the number of loan recipient entrants in 2020/21, based on SLC data, grows annually by the rates displayed in Table 4.3.
As with Master’s loans, the sharp increase (of around 17%) in doctoral loan-recipient entrants in 2020/21 can be attributed to the Covid-19 pandemic. The number of England-domiciled loan-recipient entrants is estimated to drop by 12% in 2021/22, based on end of May 2022 SLC application data. From 2022/23 onwards, the estimated annual growth in England-domiciled recipient entrants is the average of the growth rates from 2011/12 to 2018/19 of HESA doctoral entrants.
Estimates of growth in EU-domiciled loan-eligible entrants are based on analysis of outturn SLC 2020/21 data that identifies the proportion of loan borrowers that would be eligible each year under Citizens’ Rights or as one of the remaining eligible groups (not required to be eligible under Citizens’ Rights). This proportion is applied to the 2021/22 loan-eligible forecast to estimate annual growth rates thereafter.

Assuming that the course duration split of entrant students taking up Doctoral loans does not change year-on-year, we used provisional SLC management information data, as at mid November 2018, to estimate the loan take-up split by course duration displayed in Table 4.4.

The average loan (for the whole course) taken out is estimated to be £26,065 in 2021/22, by taking the average requested amount in 2018/19 (£23,900), as at end December 2018 and uprating by RPIX (outturn and forecast) in future years. For reference, the maximum Doctoral loan amount for a course starting in 2021/22 is £27,265. Annual academic year outlay is then calculated using a cohort approach, based on continuation rates estimated from HESA cohort data and the proportion of students estimated to take up a Doctoral loan as outlined above. The expected number of loan borrowers in each cohort is multiplied by the corresponding average loan amount, with the sum of the outlay from each cohort aggregated to produce a final academic year outlay figure. Like in the Master’s loans model, financial year outlay is then calculated using the assumption that two thirds of the yearly loan amount each academic year is given in the first financial year it overlaps with and the remaining third in the following financial year.
Long-term outlay forecasts
The methodology for the outlay forecast for the next five financial years for full-time (FT) and part-time (PT) undergraduate, Master’s and Doctoral loans is documented above. After this, an alternative method is used to forecast the long-term outlay.
The proportion of total borrowers from each cohort, by product, shown in Table 4.5, is multiplied by the growth rate of that cohort (found by taking the entrant growth from the long-term student numbers model for the cohort when they started) to give a total student loan borrower growth rate for the academic year. This student loan borrower growth rate is then multiplied by the previous academic year outlay forecast and multiplied by forecast RPIX. The financial year forecast is then calculated by using the assumption that two thirds of the yearly loan amount of each academic year is given in the first financial year it overlaps with and the remaining third in the following financial year, for undergraduate maintenance and postgraduate loans; for undergraduate fee loans, the assumption is that the yearly loan amount of each academic year is split evenly between the two financial years that the academic year overlaps with.

Data quality
Producing forecasts is inherently uncertain and they are very dependent on the data sources, modelling techniques and assumptions used in the model. In particular, the model assumes that the characteristics and behaviour of future borrowers will be similar to historic ones derived from SLC administrative data, which may not necessarily be the case.
The model is dependent on the Spring 2022 OBR macroeconomic forecasts that it uses to uprate fee and maintenance loans. Any significant changes to the economy from these forecasts could affect the outlays that will be made on student loans.
The model uses SLC administrative data to determine borrower numbers and loan amounts. The DfE receives data extracts from the Student Loans Company on an academic year basis that are used in the student loan outlay model. This data is consistent with the data published in the SLC Student Support for higher education in England publication.
The model uses the growth in forecasted entrants from the DfE student entrants model; see Section 3 – Data Quality. The student entrants model largely forecasts full-time undergraduate entrants to Approved (fee cap) providers eligible for tuition fee loans from Student Finance England. This specifically includes former HEIs and designated APs registered as an Approved (fee cap) provider with the OfS, see Section 3 for more detail. This does not include students studying higher education courses at FECs registered as Approved (fee cap). The outlay model assumes that the growth in students studying higher education courses at FECs is the same as former HEIs and that the growth in entrants eligible for tuition fee loans from Student Finance England is the same for maintenance loans. If the growths in these populations are not consistent then this will have an impact on the number of new entrants who are taking out loans in the model.
The model assumes that fees and maintenance loans will be uprated by forecast RPIX in future years for which fee and maintenance loan levels have not yet been announced. The model also assumes that the current student finance policies will remain unchanged. Generally, once policies have been announced they are incorporated into the loan outlay models. Therefore, any changes to the student finance policy will affect future forecasts. Any changes to student loan eligibility, quantum or terms and conditions, if implemented by Government, could affect the forecasts presented in this publication.
The forecasts for new loan products such as postgraduate loans and part-time maintenance loans are more uncertain as there is limited historical SLC data on which to base the forecasts. Instead, assumptions have to be made about the likely uptake of these products, which are more uncertain because the introduction of these products is likely to change student behaviours.
Comparing the performance of the loan outlay models to SLC outturn data in 2021-22 showed that the overall outlay forecast was approximately 1.02% higher than the outturn figure. Both the Master’s forecast and Doctoral forecast were lower than the actuals (1.2% and 5.5% respectively), with the undergraduate forecast having an over forecast (1.2%).

The data shows that almost half of students who received loans in 2019/20 (as of April 2021) had a household residual income of under £25,000. Just under a quarter of students do not provide a figure for household residual income.
Table 4.7: Outlay and Student Numbers by Household Residual Income
The DfE student loan earnings and repayments model is the financial model used to estimate the cost of income contingent student loans to Government. It forecasts the repayments that the Department expects to receive on its expenditure on student loans.
The model is a micro-simulation model. It forecasts student loan repayments by estimating future earnings for a sample of individual student loan borrowers, and applies the loan repayment policy to each borrower, before aggregating the results to estimate totals for the population as a whole. For each loan borrower, it predicts their next year’s earnings, and when this is repeated it generates an earnings path. Where historical information on earnings is available the model makes use of this. Earnings predictions are based on the borrower’s level of study, gender, years since SRDD (Statutory Repayment Due Date), age and other information. This allows the model to capture individual changes in earnings over the borrower’s working lifetime.
Once a borrower’s earnings have been forecast their repayments, interest and loan balances are calculated year by year for the length of their repayment term, or until they finish repaying their loan. Further adjustments are made to some borrowers’ repayments to allow for voluntary repayments, overseas repayments, and differing obligatory repayments resulting from non-standard earnings distributions across months of the year or across multiple jobs.
The model forecasts repayments for English domiciled students studying in the UK and EU domiciled students studying in England. Earnings forecasts are made for undergraduates (first degrees and sub-degrees) and PGCE loan borrowers based on historical administrative data for comparable loan borrowers and historical administrative earnings data for the UK residents. For Master’s and Doctoral loan borrowers, earnings are modelled by applying a percentage uplift to an earnings forecast for a comparable first degree student.
The main data sources used in the model are:
SLC administrative data – provides details of borrowers and the loans they take out, used to forecast earnings and employment status in early repayment years. Used for modelling migration, repayment frictions and repayments made directly to the SLC.
Longitudinal Education Outcomes (LEO) - used in earnings and employment models in early repayment years.
HMRC administrative earnings data – used in earnings model from year 11 of repayments onwards.

Student loan repayment policies
ICR loans require borrowers to make repayments based on their annual income, starting from the April after they have left their course. Under each policy, borrowers are required to make repayments each tax year equal to a percentage of their income above a set repayment threshold until either they have fully repaid their loan balance, or their loan is cancelled. Loans are cancelled if the borrower dies, if they still have an outstanding loan balance at the end of their repayment term, or if they are in receipt of a disability related benefit and are permanently unfit for work. Loans accrue interest during and after the borrower’s course, which is added to their loan balance.
A borrower becomes liable to repay their loan on the 6 April (start of the UK tax year) after they complete or withdraw from their course, at which point their repayment term starts on what is known as their Statutory Repayment Due Date (SRDD). There are two exceptions to this:
Part-time loan borrowers will enter repayment at the start of the tax year after four years have elapsed since the first day of the first academic year of the course, even if they are still studying.
When a loan product is first introduced the earliest SRDD for some borrowers may be later than it would usually be. For example, all Plan 2 borrowers that completed or left their courses before April 2016 had an SRDD of April 2016, even though under the usual rule some would have had an SRDD up to three years earlier. For Plan 5 borrowers, first possible SRDD is yet to be announced. For modelling purposes it is assumed to be the first April after borrowers complete or withdraw from their course.
A summary of the key repayment policy details for each loan product is shown in table 5.1 below.

Each loan product has a separate income repayment threshold, above which repayments are made. Figure 5.2 shows the forecast repayment thresholds for each policy. All historic Plan 1 and Plan 2 threshold levels are published. The Plan 1 threshold is set at £19,895 for tax year 2021-22, and at £20,195 for tax year 2022-23. It will subsequently increase each year based on RPI. The Plan 2 threshold was initially set at £21,000 from 2016-17 to 2017-18 before rising to £25,000 in 2018-19,to £26,575 in 2020-21, and to £27,295 in 2021-22. The threshold will remain at £27,295 until the end of tax year 2024-25, after which it will increase in line with RPI. The initial Plan 5 repayment threshold is set at £25,000 until 2027-28, after which it will increase in line with RPI. If a borrower has Plan 1 and Plan 2 loans, they pay back 9% of income over the Plan 1 threshold. If their income is under the Plan 2 threshold repayments only go towards the Plan 1 loan. If income is over the Plan 2 threshold, repayments will be split between both loans. It will be confirmed how Plan 5 loans are incorporated into these rules in due course, though repayments will remain fixed at 9% over the relevant thresholds. The Plan 3 repayment threshold is £21,000 from when the first borrowers become liable to repay in 2019-20 and 2020-21, and it has been announced that it will remain at that level until 2022-23. More details on how much the borrower repays are available at gov.uk. To enable future repayments to be forecast, for modelling purposes it is assumed that from 2022-23 the Plan 3 loan will rise in line with Office for National Statistics (ONS) average earnings growth statistics. Thestudent loan repayment model forecasts future repayment thresholds using OBR forecasts for RPI.

England, financial years 2021-22 to 2051-52
In addition to the repayment threshold, Plan 2 also has two interest thresholds. Once Plan 2 borrowers are past their SRDD their interest rate varies depending on income. If their income is below or equal to the lower interest threshold their interest rate is RPI, at or above the upper interest threshold it is RPI+3%, and for anyone with an income in between it varies linearly between the two. The lower interest threshold is the same as the repayment threshold, while the upper interest threshold was set to £41,000 in 2016-17 before increasing to £45,000 in 2018-19, and £49,130 in 2021-22. It will remain at £49,130 until the end of tax year 2024-25. In subsequent years both thresholds are forecast to rise in line with RPI.
Student loan borrowers resident in the UK generally make their loan repayments through the tax system to Her Majesty's Revenue and Customs (HMRC), either in-year through their employer via Pay As You Earn (PAYE) or the following year via a Self-Assessment tax return. Borrowers residing overseas are required to contact the Student Loans Company (SLC) and arrange to make repayments directly to them. Borrowers can also choose to make early repayments on their loan directly to SLC, and when a borrower is close to fully repaying their loan SLC will alert them and, to avoid over-repaying via the tax system, they can arrange to make their repayments via direct debit directly to SLC rather than through HMRC.

A population of past and future loan borrowers is created containing information about borrowers’ loan amounts, their courses, and various other information about them. To forecast a borrower’s earnings the model needs data on their characteristics such as:

Combined courses and others not coded: Combined or unknown subject area
For existing loan borrowers this information comes from SLC administrative data, with some adjustments made to course lengths for those students still on courses using HESA data to simulate some dropping out or changing the length of their course in the future. For those still on courses, future loan amounts are estimated to be the same as their most recent year of loans, uprated by forecast RPIX where appropriate. Some adjustments are also made based on historical SLC data to allow for medical students receiving reduced loan amounts in the 5th and 6th years of their courses and for some “sandwich” students who receive different loan amounts in their placement year.
Some historical loan borrowers are chosen at random (with frequencies based on historical data on borrowers taking out multiple loans) to start new courses in future years for which they take out student loans (e.g. a graduate may subsequently take a PGCE course for which they can receive a further loan), while the characteristics of all other loan borrowers starting on courses in future years are created by choosing borrowers at random from the most recent historical year of entrants. The number of entrants assumed to start courses each year for which they receive student loans is estimated by applying the annual growth rates from the student entrant numbers in the DfE student numbers model to the number of borrowers in the most recent year of entrants in the SLC data.
Where a new policy is being introduced and no information is available on historical loan borrowers’ characteristics, the distribution of characteristics for future loan borrowers are estimated based on historical HESA data for students on the courses for which loans will be available, with average loan amounts assumed for each borrower based on the DfE student loan outlay model.
Earnings forecasts
The part of the student loan earning and repayment model that forecasts earnings is known as the earnings model. The earnings model predicts earnings and earnings status for each individual for up to 40 years past their SRDD, by which any outstanding loan balances will have been written off.
An estimate of the earnings path of loan borrowers is necessary to estimate a borrower’s repayments across their repayment term. As loans generate interest throughout their repayment period, the path of an individual’s earnings, rather than their total earnings over the repayment period, has a significant effect on the amount of the loan the borrower will repay.
Figure 5.3 depicts two hypothetical earnings scenarios, A and B, for a loan borrower with the same SRDD and same nominal loan balance at their SRDD of c. £35,000. In both cases the individual has the same total nominal earnings over their supposed 30 year repayment period however in scenario B the loan is completely repaid, whereas in scenario A part of the loan (c. £12,000 nominal loan balance) is written off.
The earnings model is divided into two parts, based on the number of years between the forecast year and a borrower’s SRDD. The first 10 years after SRDD are predicted using the ‘early-career earnings model’ and years 11 to 40 are predicted using the ‘long-term earnings model’. The models are split in this way due to different data availability for these periods.
Forecasts are produced based on the assumption that future earnings will follow the same trajectories as those seen in recent historic earnings. In the early-career model these historic earnings are derived from two sources:
Student Loans Company (SLC) administrative data from 2001 to 2020
Longitudinal Education Outcomes (LEO) data from 2014 to 2019
The SLC data includes earnings and employment status in each tax year following a borrower’s SRDD as well as characteristics of the borrower’s most recent period of study, such as subject of study, provider and course level. SLC data does not, however, include the earnings of those who have fully repaid their loan and therefore, once high earners start to repay their loans in full, the dataset provides an unbalanced picture of the earnings of the graduate population. To overcome this, where borrowers have repaid their loans earnings are taken from the LEO dataset where available, based on fuzzy matching between the SLC and LEO datasets. The model is trained on a subset of the data, from 2014 to 2019, containing earnings and characteristics for borrowers up to 10 years after SRDD.
In the long-term earnings model, historic earnings are derived from HMRC administrative earnings data for 10% of the UK population from 2012 to 2020. This data includes a person’s age and gender, as well as their PAYE and self-assessed earnings. It is not possible to distinguish whether or not people in this dataset are graduates or not. Therefore, it would not be suitable for predicting earnings earlier in a graduate’s career, where we expect a degree qualification to have a signalling effect resulting in graduates earning more on average than non-graduates, even once gender, age and earnings history are taken into account. By 11 or more years after SRDD we assume the label of graduate or non-graduate is immaterial, as any signalling effect is already encompassed within individual’s earnings history (given age and gender). Therefore the HMRC data offers a richer source of data on earnings for people later in their careers, compared to the SLC/LEO datasets. The Average Weekly Earnings (AWE) index, published by the ONS, is used to re-baseline historic earnings into 2014-15 financial year terms, allowing us to make predictions based on the full time-series of earnings, having already accounted for wage inflation between years.
To create an earnings path for each borrower, both models search their respective training datasets to find the 10 most similar individuals based on various characteristics. In the early-career model, similar individuals are selected from the population with the same number of years since SRDD. The variables that define the proximity between individuals are their Higher Education Institute type, domicile (England or EU), subject of study, gender, age, whether or not the borrower withdrew from studies before graduation and up to three years of previous PAYE and self-assessed earnings. In the long-term model, individuals are selected from the population with the same age and gender, and the previous three years of PAYE and self-assessed earnings are used to define proximity. This proximity is measured by Euclidean distance. To produce an earnings forecast, the model then selects one of those individual’s known earnings in the following year, choosing the individual based on a weighted probability, where weights are the square inverse of the Euclidean distance. Where the weights of the 10 selected individuals are identical, the model selects one at random. Annual PAYE and self-assessed earnings are forecast for each borrower in the sample, and this step is repeated over subsequent years, to generate an earnings path for each individual. Forecasts are produced in 2014-15 financial year terms, and later re-scaled using OBR earnings growth forecasts.
Whilst undertaking a course we do not forecast earnings for borrowers. This includes part-time loan borrowers studying for longer than 4 years who have an SRDD in the fifth April after the start of their course, even if they are still studying. Similarly, we do not account for the impact of earnings prior to taking up a university course on earnings on completion. As such, estimated earnings for part-time loan borrowers may be lower than actuals on entry into the labour market. However, we do not expect this impact to be long lasting and modelled earnings for part-time loan borrowers will tend towards those of full-time loan borrowers as they progress through their career.
Earnings forecast outputs
At this stage in the modelling we have generated annual equivalent earnings for those borrowers in employment in the UK at an individual level. These can be aggregated to provide insights to the earnings forecasts underlying the repayment forecasts.
For the cohort of borrowers with an SRDD of 2021 we forecast the proportion employed (defined as UK earnings above zero in a financial year) over 30 years (Figure 5.4), as well as the median forecast earnings each year, for those employed, in 2021-22 values (Figure 5.5). We find that female borrowers have slightly higher employment than male borrowers (Figure 5.4), but have lower earnings (Figure 5.5).
Figure 5.4: Forecast proportion of borrowers in employment in the UK by gender: 2021 SRDD cohort
Financial years 2021-22 to 2050-51
Figure 5.5: Forecast median annual earnings of those in employment by gender: 2021 SRDD cohort
Financial years 2021-22 to 2050-51, earnings in 2021-22 earnings values
Forecast median earnings for the first year past SRDD are £20,400 in 2021-22 values with little difference between male and female earnings. Median earnings for male and female borrowers diverge over the loan term growing to an average gap of £7,700 in 2021-22 earnings values over the final 10 years of the loan term.
The model assumes that the employment and earnings paths of individuals in the future will be similar to those seen historically in SLC and HMRC administrative earnings data. This includes historic patterns for employment and earnings by gender, which will not necessarily be the case, especially in the long term.
The distribution of forecast earnings by gender is further broken down in Figures 5.6 and 5.7. The distribution of female earnings is more closely grouped around the median, with 50% of female borrowers earning within £13,500 of median earnings. In comparison the male earnings distribution is more dispersed, with the top decile of male borrowers earning over the 30-year loan term on average 1.3 times that of female borrowers in the top decile.

Mortality
ICR loans can be cancelled prior to the end of the repayment term if the borrower dies. The probability of death in a given year is derived, based on the borrower’s age and gender, from ONS life tables and SLC data. SLC data shows lower write-off levels than would be expected from ONS mortality rates, most likely reflecting that graduates have lower mortality rates than non-graduates of the same age. But the historic SLC data has little coverage of student loan borrowers aged above their mid-30s, so a weighted average of the two sets of mortality rates is taken that gives a high weighting to the SLC data at younger ages and to ONS data at older ages.
There are reasons other than death why a loan may be written off before the end of a borrower’s repayment term, however, the level of these write-offs is comparatively small and as such they are not included in the model.
Repayments made directly to SLC
In addition to obligatory repayments collected through the UK tax system, repayments can also be paid directly to the SLC. These fall into three main categories:
Voluntary repayments (prepayments) – These are (early) repayments made by the individual in addition to their obligatory repayments.
Payments from overseas – Repayments from borrowers situated overseas cannot be collected through the tax system. Overseas borrowers make obligatory repayments direct to the SLC based on their income and the earnings threshold for their country of residence.
Direct debits – In the last couple of years of payment the SLC offer the borrower the opportunity to repay the rest of their loan through a direct debit to prevent overpayment.
The probability of a borrower making a voluntary repayment each year is generated from a multinomial logistic regression model based on SLC administrative data. Voluntary repayments are particularly dependent on the magnitude of the debt outstanding and the number of years into the repayment period, as well as whether a borrower has previously made a voluntary repayment. The regression model also takes into account obligatory repayments, whether a borrower is close to repaying their loans in full, earnings and the proportion of the balance previously paid via voluntary repayments. Most voluntary repayments come from borrowers with low amounts of debt in the first few years of repayment. If a borrower is due to make a voluntary repayment in the model, they are either categorised as repaying their outstanding balance in full or repaying a percentage of the debt outstanding as a direct repayment. For those borrowers not repaying their outstanding balance in full, the percentage to be repaid is derived using a second logistic regression model. This model takes into account voluntary repayments in prior years, the numbers of years into the repayment period, outstanding balance, earnings, and obligatory repayments.
Borrowers can also make overseas repayments. The probability of a borrower making an overseas repayment each year is generated from a decision tree model based on SLC administrative data. The decision tree model considers the borrower’s plan type, earnings over threshold, and previous overseas repayments. The size of the repayment is selected at random from a distribution of repayment amounts based on the borrower’s overseas repayments last year and their plan types.
Postgraduate loan borrowers
Limited historic data on postgraduate loan borrowers is available as they are new loan products (introduced in 2016). In addition, information on postgraduate earnings and behaviours from survey data is limited, as in population surveys the proportion of the survey respondents that have postgraduate degrees is very small. Therefore, the student loan repayment model generates employment and earnings forecasts for postgraduate loan borrowers using the same earnings model as for first degree students with the same characteristics, to which it then applies a fixed uplift to earnings in all years to account for the higher earnings postgraduates are expected to have.
For Master’s borrowers an earnings uplift of 8.9% is applied for male borrowers and 10.3% for female borrowers. This is based on research that estimated this to be the average marginal earnings gain for Master’s students on top of their undergraduate degree (Conlon & Patrignani, 2011). For Doctoral students, an earnings uplift of 8.0% is applied for male borrowers and 6.0% for female borrowers. These uplifts are based on results for Doctoral students from the same research, though they have been adjusted down to account for trends associated with subject of study and HEI group. This adjustment aims to account for factors such as this, which were not considered directly in the research due to the available sample size but are important in student finance forecasting. For example, the population of students expected to take up Doctoral loans is not representative of all Doctoral students since the availability of other funding sources (such as industry or research council funding) may differ by subject of study. These uplifts for Master’s and Doctoral students are not directly comparable, as the other factors will also affect the average earnings for each course level.
As there is only very limited administrative information available, postgraduate loan borrowers are assumed to have similar behaviours as an equivalent first degree student for factors such as such as voluntary repayments, overseas repayments and mortality.
Obligatory repayment amounts
Once annual earnings are calculated and non-employment, migration, and mortality are taken into account, the obligatory repayments are calculated according to the deterministic repayment rules for that year. Once obligatory repayments have been calculated, a repayment frictions model is applied to them to reflect the historic differences observed between repayments due based on the deterministic calculation and observed obligatory repayments. These frictions can be due to e.g. seasonal earnings patterns (which could result in higher repayments than otherwise) or the borrower’s earnings coming from multiple jobs (which could result in lower repayments than otherwise).
Repayment frictions
The probability of a borrower having a repayment friction each year is generated from a decision tree model based on SLC administrative data. Incidence of repayment frictions are dependent on the magnitude of the debt outstanding for loans of various plan types, earnings in both the current and prior year, the change in earnings, the number of years into the repayment period, as well as a borrower’s repayment frictions in the prior year.
If a borrower is due to have a repayment friction in the model, they are either categorised as having a positive friction (borrower repaying more than they are obliged to based on earnings), a large negative friction (borrower repaying less than they are obliged to based on earnings), or a small negative friction (less than £15).
For those borrowers due to have a small negative friction, the repayment adjustment is taken from a random distribution of historic small negative repayment frictions. For borrowers due to have a positive friction, the repayment adjustment is selected at random from a distribution of repayment amounts (expressed as percentages of earnings over the repayment threshold) based on the borrower’s plan types, earnings over threshold and earnings change from the prior year. Finally, for borrowers due to have a large negative friction, a multiple regression model is used to determine the size of the repayment friction. This model uses a borrower’s frictions in the prior year, earnings change from the prior year, obligatory repayments in the prior year, and obligatory repayments in the current year.
Repayment amounts and debt outstanding
All obligatory, voluntary, and overseas repayments that the borrower makes each year are summed together, up to a maximum of the borrower’s remaining loan balance. Borrowers are assumed to stop repaying their loan once their loan balance reaches zero. The model does not account for borrowers making overpayments or receiving refunds after overpaying.
To calculate the size of a borrower’s loan balance, borrowers are given annual outlay amounts while on their course based on the distribution of outlay amounts of historical borrowers in the SLC data, uprated in line with forecast RPIX depending on the appropriate loan policy. Capitalised interest is accumulated and added to the borrower’s balance each year, with any repayments subtracted from it. The size of the borrower’s debt is calculated on this basis each year until they either fully repay their loan or until their loan is cancelled, either due to mortality or because they reached the end of their repayment term.
In reality HMRC share repayment data with SLC on a weekly basis, but as an approximation all PAYE and voluntary repayments in the model are assumed to be made in the middle of the financial year. Repayments from self-assessment (SA) are correctly assumed to be made at the end of each January, for the previous financial year. Interest for the first half of the financial year is added to the debt outstanding at the start of the year before PAYE and voluntary repayments are made, then the interest for the next four months is added after they have been deducted, then finally the interest for the final 2 months is added after any SA repayments have been deducted. In academic years where a borrower is forecast to receive loan outlay, these are assumed to occur in three instalments at the end of September, January and April. Interest is accrued on these payments and applied to the loan balance accordingly.
If a borrower’s loan is cancelled this is assumed to happen at the end of the financial year, as this is the point when cancellations will occur at the end of a borrower’s repayment term, which are expected to account for the large majority of cancellations.
Interest rates each year are calculated from RPI, the Bank of England base rate (Plan 1 only) and borrowers’ income in line with the appropriate policy. RPI and Bank of England base rate figures are based on OBR forecasts. The interest rates for each part of the year are calculated and then combined into an annual average that is used across the financial year. For all loan plans, the RPI figure used in calculating interest rates changes each September to the March RPI figure published by ONS in the same year, but as OBR only publishes quarterly forecasts (and in the long run only annual forecasts) the model uses the forecast for the equivalent January to March quarter in the short run, and the annual figure for the same financial year in the long run. For Plan 1 loans, quarterly base rate forecasts are averaged over each financial year, with this average +1% compared to the financial year RPI to determine which to use for interest rates that financial year.
Population totals
Forecasts for individual loans are aggregated together to estimate totals for the whole student loan population. Rather than making estimates for the whole population of loans, to make the model more efficient (i.e. quicker to run), forecasts are made for a sample of loans, with weightings applied to these loan results to “scale up” to the correct totals for the whole population.
A random sample of 200,000 borrowers is used for each loan product, covering entrants from the first year that the loan product was introduced up to entrants in academic year 2025/26 (excluding those that have already finished repaying their loans or had them cancelled).
As the Doctoral loan is a new product from 2018/19, limited outturn data is available and so borrowers are based upon historical HESA data. Until sufficient administrative data becomes available, the same sample size of Doctoral borrowers is used, and the results are scaled down to match new forecasted entrant numbers.
The scaling used to increase the sample results to population totals is weighted based on several variables to reduce the sampling bias in the model. The variables used in the weighting are course start year, SRDD, gender, course level, whether the course is a STEM subject, plan type, whether the loan is for full time or part time study, and how many loans the borrower has.
The Resource Accounting and Budgeting (RAB) charge and the stock charge
The RAB and stock charges are the estimated cost to Government of providing a subsidy for the student finance system. They are the proportion of loan outlay (the RAB charge) and of the total outstanding loan balances (the stock charge) that are expected to not be repaid when future repayments are valued in present terms.
To calculate the RAB charge, the total outlay in a given year is added up and compared to the total net present value (NPV) of the repayments that are anticipated in connection with this same outlay. The RAB charge is calculated as
Similarly, the stock charge is calculated by summing all outstanding loan balances at the start of the year and comparing this to the total net present value (NPV) of the repayments that are anticipated in connection with these loans. The stock charge is calculated as
The NPV of future repayments is calculated by discounting all future repayments at a rate of RPI-1.1% per year until the end of financial year 2029-30, and -0.2% per year from financial year 2030-31, to the same point in time as the loan outlay or loan balance. This is the discount rate for financial instruments set by HM Treasury (HMT) and is intended to reflect of the cost of Government borrowing.
Student loans are valued in DfE’s annual accounts in line with the International Financial Reporting Standard (IFRS) 9, under which where future cash flows are discounted to measure the fair value of a financial asset, this should be done using the higher of the rate intrinsic to the financial instrument or the Her Majesty's Treasury (HMT) discount rate. For student loans the intrinsic rate would be the discount rate that gave a RAB or stock charge of 0%, so the HMT discount rate is used provided the RAB charge is greater than 0%. Should the HMT discount rate result in a RAB charge calculation giving a negative value then the intrinsic rate is used instead, meaning that that RAB charge will take a value of 0%.
In the model, RAB charges are calculated for the loan book as a whole by first calculating the NPV of individual borrowers’ repayments, then for each year aggregating these together across all borrowers and comparing them to their total loan outlay in that year. Stock charges are calculated in the same way, aggregating the NPV of individual’s repayments before aggregating them to a population total and comparing this to the face value of the loans at that point in time. Where a borrower has more than one year of outlay or has both future loan outlay and an existing loan balance that will be included in the stock charge, future repayments are allocated between each year of their loan outlay and their existing loan balance in proportion to the relative balances of each loan when valued at the same point in time (i.e. taking into account interest accrued on the earlier loan balances). A RAB charge is no longer produced for Plan 1 loans as very few Plan 1 students are still receiving loans.
Data quality
RAB and stock charge estimates require earnings and repayments forecasts covering the subsequent 40 years. These forecasts depend heavily on input data sources, modelling techniques and assumptions used in the model. Consequently, forecasts are inherently uncertain owing to the inevitable uncertainties associated with these sources, assumptions, and methods. For example, the model assumes that the distribution of future earnings paths will be similar to historic distributions derived from SLC and HMRC administrative data, which will not necessarily be the case, particularly in the long term.
The model is dependent on the OBR macroeconomic forecasts that it uses to uprate earnings, calculate interest rates and repayment thresholds, and to discount future repayments to present values. Any significant changes to the economy from these forecasts could affect the repayments that will be made on student loans.
Tables 5.2 includes a demonstration of the sensitivity of the Plan 1 stock charge, and the full-time and part-time higher education RAB charge for Plans 2 and 5, to variations in the OBR forecasts. Table 5.2 shows that a 1pp lower Bank of England base rate from financial year 2022-23 onwards could increase the Plan 1 stock charge by up to 2pp. The effect of RPI being consistently higher by 1pp from 2022-23 results in an increase of RAB by 6pp for full time and by 4pp for part time Plan 2 loans. The same scenario for earnings growth has an impact of 6pp for full time and 4pp for part time Plan 2 loans. The RAB charge of Plan 2 full time loans is more sensitive to the change in macroeconomic determinants than RAB charge of Plan 2 part-time loans. This is because the loan amounts are generally higher for full-time loans which results in longer repayment period and thus longer period over which the 1pp change in the determinant accumulates.
For Plan 2 RAB charges the impact of varying some key policy parameters is also demonstrated in Table 5.3.

The model uses SLC administrative data to determine borrower characteristics, loan amounts, earnings in the first three years of their repayment term and repayments made directly to SLC. As an administrative source the historical SLC data should be broadly accurate, although the earnings and direct repayment forecasts rely on future borrowers having similar behaviours to historic borrowers.
Where new loan products are being introduced, the forecasts are more uncertain as there is less historical information available on which to base forecasts and more uncertainty about what student behaviours will be in response to policy. This is particularly the case for the two postgraduate loan products, for which the earnings forecasts are less well developed than for undergraduates and for which there is very limited historical information about loan borrowers’ characteristics and behaviours.
Since the 2021 publication there have been a number of changes to student loan policy, updated forecasts of student entrants and the macro-economy and newly available data from SLC. These have all combined to change the forecast RAB charges for 2021-22 in comparison to the previous publication. The effect of these factors on the RAB forecast is shown in Table 5.4. The figures are rounded to the nearest percent or percentage point and may not appear to sum due to the rounding.
Since the previous version of this publication in June 2021, the RAB charge forecast has fallen by around 9ppt in 21-22 and 24-27ppt from 22-23 to 26-27. The narrative on how the RAB charge changed from June 2021 to January 2022 and then to the post HE finance reform update is described in Annex B of Higher education policy statement & reform consultation equality analysis. In summary though, the key updates here were a change to the Financial Instrument Discount Rate from +0.7 to -1.1, which reduced 21-22 Plan 2 ft RAB by 14ppt, and then the changes to the student finance terms through reform of repayment terms which reduced RAB by more than 13ppt each year.
Since the equality analysis, we have split the forecast into Plan 2 and Plan 5 - with the new Plan 5 representing loans taken out by borrowers from September 2023. The plans have different repayment policies with different proportions of the outlay expected to be repaid. The RAB charge table (Table 5.4) presented here shows an estimate of the combined Plan 2ft and Plan 5ft loans for the July-2022 publication - whereas in reality we now forecast these separately.
In contrast, changes to the RAB charge since the equality analysis have been more minor. The 21-22 RAB charge has increased once more as reform savings are now not counted in financial year 21-22 (as legislation did not pass through in the 21-22 financial year), and the RAB does not drop off as rapidly as it did at the equality analysis publication because we have moved to a new repayments model which (amongst other improvements) is better at reflecting, even long term, borrowers who take out multiple loans. Other changes since the equality have included:
Policy updates: implementation of the announced 7.3% interest rate for academic year 2023/24
Economic updates: updating to the latest published OBR macroeconomic determinant forecasts (from their March 2022 Economic and Fiscal Outlook and July 2022 fiscal risks and sustainability report) and ONS data outturns
Methodology updates: switching to a new repayments model

Comparison of forecast earnings with actuals
To assess the accuracy of the forecasted earnings distributions, forecasts from prior years can be compared to actual earnings that subsequently become available in the SLC administrative data. For example, Figure 5.8 shows the distribution of actual earnings in 2019-20 and 2020-21 for those borrowers who were repaying their loan, compared to predictions from the earnings model. The forecasted and actual distribution patterns are similar, with the closest matches around the median earnings.
Figure 5.8: The distribution of above-zero earnings in 2019-20 and 2020-21 for borrowers still in repayment, forecasts compared to actuals
Note that Figure 5.8 shows a fall in predicted and actual earnings from around year 8 onwards. This is due to the characteristics of the borrowers available for comparison in the SLC administrative data - higher earners with plan 1 loans are likely to have repaid their loans, and so are not available for comparison. The distribution of earnings for those still in repayment therefore changes with the number of years since the borrower’s SRDD. Figure 5.9 shows that this change in earnings distributions with years since SRDD is matched well in the earnings forecasts.

Comparison of forecast repayments with actuals
The student loan repayment model is designed to forecast repayments across loan borrowers’ repayment terms. Comparisons between forecast repayment totals (one or two years ahead) for individual years and the actual outturn data can give an indication of how well the model has been performing. Table 5.5 shows how recent outturn figures compare with the forecasts made at the time. Improvements are made to the student loan earnings and repayment model each year and the data used in it are updated, so forecasts are shown as made at both the start and end of each tax year. Note that from July 2022 a new and much improved repayments model is in use and so we would expect forecasts from that point onwards to be typically more accurate than those in the table below.

These figures include repayments made directly to SLC and PAYE and Self Assessment repayments made via HMRC. Direct repayments are recorded against the year they are received by SLC, HMRC repayments are recorded against the year of the earnings they relate to.
Repayments across all loan products are included in the data. Up to 2015-16 only Plan 1 borrowers were eligible to make obligatory repayments, though Plan 2 borrowers could make voluntary repayments. From 2016-17 the first Plan 2 borrowers became liable to make obligatory repayments, and the first Plan 3 borrowers will in 2019-20. Variances between forecasts and actuals will be due to a range of factors, including:
Macroeconomic shifts and new data
Modelling variances (i.e. simplifications and assumptions made in the modelling) and random variation (e.g. through sampling)
Operational factors that result in lower than expected collections.
By the time of the second forecast shown for each year the macroeconomic data for the year will largely be known, so the forecast is less dependent on OBR macroeconomic forecasts. However, modelling changes and other data updates will also have occurred so changes between the two forecasts also include other factors.
Advanced Learner Loans (ALLs) are tuition fee loans to help those aged 19+ at the start of their course meet the up-front costs of regulated Further Education (FE) qualifications at Levels 3 (equivalent to 2 A levels) to Level 6 (equivalent to an undergraduate degree) in England. ALLs were introduced in 2013/14 to those aged 24+ and at levels 3-4 following a refocusing of the Adult Education Budget on adults requiring skills and learning to equip them for work, an apprenticeship or further learning.
Following a public consultation in 2014, the extension of ALLs in academic year 2016/17 to those aged 19-23 and to Levels 5-6 has been the programme’s most significant change.
The RAB charge for ALLs is the estimated cost to Government of borrowing to support the ALLs system. The purpose of the DfE ALLs model is to assist in valuing the existing ALLs loan book and to provide forecasts for budgeting purposes.
The RAB charge is an estimate and it is heavily dependent on assumptions around the future income of ALLs borrowers. The methodology, data sources and assumptions are presented in the section below.
Methodology
The ALLs model is a micro-simulation model. The model creates thousands of simulated borrowers with a variety of characteristics. Each borrower is assigned a debt and their earnings are projected for the length of their repayment term. Then the repayment rules are applied to each borrower to estimate their repayments, individual loan balance and interest for the length of their repayment term. The assumptions used in the simulation model fall into five main sections below:
Borrowers’ characteristics and their loan details
Macroeconomic assumptions: Average Earnings Index (AEI) and Retail Price Index (RPI)
Loans policy assumptions
Annual income post learning: employment status, income and income distributions
4.1. Labour market status
4.2. Position on income distribution
4.3. Annual income in nominal terms
Life events
5.1. Mortality
5.2. Migration
5.3. Permanently unfit for work
5.4. Extending working lives.
5.5. Voluntary Repayments
1. Borrowers’ characteristics and their loan details
Analysis of administrative Student Loans Company (SLC) data informs the input assumptions on the characteristics of borrowers in each academic year, the courses they study and the average loan size they take. The complete list of input parameters are:
Total number of new borrowers;
Proportion of borrowers on multiple courses;
Course type (A levels, Access to HE, Level 3 Diploma, Level 4 Diploma, Level 3 Certificate, Level 4 Certificate and Level 5/Level 6 courses);
Gender split of borrowers;
Age distribution: 19-71 by single year of age;
Course duration in months: 1-24 months;
Course start month across academic year;
Average loan size by type of course (A levels, Access to HE, Level 3 Diploma, Level 4 Diploma, Level 3 Certificate, Level 4 Certificate and Level 5/Level 6 courses).
Non-completion rates by type of course.
2. Macroeconomic assumptions
The model uses the Office for Budget Responsibility (OBR) assumptions on future average earnings growth (AEI) and RPI projections to calculate future repayment thresholds, interest rates and discount rates for the ALLs. The model also uses the AEI projections to uprate borrowers’ future earnings. Course costs are uprated by Consumer Price Inflation (CPI).
3. Loans policy assumptions
Loans are currently available to learners aged 19+ who are studying Level 3 and above qualifications. The loans are repaid at a rate of 9% of pre-tax earnings above the lower repayment threshold. ALL borrowers are either liable for a plan 2 or plan 5 loan product and their main repayment conditions are described in Table 5.1: Key policy details for each loan product.
Additionally, there are a number of scenarios where a borrower may have their outstanding loan written off. These are;
borrowers who study Access to HE courses and complete a higher education course. The model assumes that half of Access to HE borrowers are eligible for this.
if a borrower’s course is no longer offered by the provider. The model assumes that there is a 1 in 600 chance that the borrower will be eligible for this.
From April 2021, learners aged 19 and older who take their first full level 3 qualification will be grant funded for a number of level 3 qualifications, and therefore do not require an advanced learner loan. From April 2022, any adult in England earning under the National Living Wage will also be able to access these qualifications for free, regardless of their prior qualification level.
4. Annual income post learning – employment status, income and income distributions
The key assumption in the model is the future annual income of borrowers after finishing their course.
ALLs are income contingent, i.e. borrowers repay the loan only if their annual income is above the lower repayment threshold, and their repayment amount is based on their income. Annual incomes are the basis for calculating loan repayments and interest; and getting good income estimates over the working life of borrowers is critical to estimating the RAB charge.
Income modelling starts for a borrower in the first financial year after completing their course. In most cases this will be the first year they are due to make repayments, except during the first years of the policy where it was legislated that the first repayments would not be due until 2016-17.
In every simulation each modelled borrower will go through processes to:
Set labour market status – transition between ‘employed’, ‘self-employed’ and ‘no income’;
Assign position on income distribution – one of the 25 quantiles and
Assign annual income based on their position in the income distributions.
The income distribution is split into 25 equal quantiles, so each quantile represents 4% of the income distribution. Quantile 1 = the lowest earning. The number of quantiles was determined by considering the greatest detail that the LFS could provide whilst still providing robust estimates.
The process is summarised below in figure 6.1:
Figure 6.1: Income modelling for ALL borrowers
4.1 Labour market status
Labour market status in a given year is modelled using a discrete probability matrix which supports three possible outcomes: ‘no income’, ‘employed’ and ‘self-employed’. The matrix has different probabilities depending on the characteristics of the borrower:
Course level: Level 4+, Level 3
Gender: male or female
Age: single year of age
Years since completed learning: one year, or more than one year
Current labour market status: no income, employed or self-employed
Current year income: one of 25 quantiles, or zero if not in employment
The data source for the analysis is 68 quarters of Labour Force Survey (LFS). The model uses two sets of labour market assumptions:
Initial labour market status for those in the first full financial year after their SRDD.
Probabilities of changing labour market status in all subsequent years.
In the first year after SRDD the model has no knowledge about the working history of each borrower so borrowers are assigned a labour market status only in accordance with the overall employment rates for that age, gender and course level. (Ideally, the data would be further restricted to learners that are one year post learning but there is insufficient data in the LFS to support this. The initial employment status is quickly eroded by the subsequent employment transition probabilities so has a fairly limited impact on the forecast.) In all subsequent years, each borrower has a probability of changing labour market status, this time taking into account their current labour market status and income quantile (if in employment).
The income based labour market changes from the employee population are used as a proxy for the self employed, i.e. if an employed borrower at the bottom of the income distribution has a greater chance of becoming unemployed compared to someone at the top, then a self-employed borrower at the bottom of the income distribution also has a greater chance of becoming unemployed compared to someone at the top.
4.2 Position on income distribution
After labour market status is established in the previous stage, the model assigns the borrower to a quantile on the income distribution. As with labour market status, the model assigns future income quantiles, using different probabilities depending on the characteristics of the borrower:
Course Level: Level 4+, Level 3
Gender: male or female
Age: single year of age
If in work: current income: one of 25 quantiles
If out of work: previous income when last in work: one of 25 quantiles or zero if never previously modelled in work.
Income information for the self-employed is not used, and so it is assumed that transitions across the income distribution for those who are self-employed occur with the same likelihood as for those who are employed.
The LFS data only have sufficient information to compare year on year income, they do not hold robust income information from previous employment spells further back in time. As a simplification it is assumed that a borrower returns to work at the same position on the income distribution as they were in their most recent modelled income spell, e.g. if they left work in quantile 10 then when they return to work they will return in quantile 10.
The LFS data suggest that typically those entering work are on lower incomes than the equivalent group leaving work. This would suggest a natural decay in position on the income distribution between jobs, i.e. that learners should return at a lower position on the income distribution. In practice this does not produce a good modelling solution as it creates a heavy penalty for being out of work in a single year and produces unexpected lifetime income paths inconsistent with the original simplified assumption.
4.3 Annual income in nominal terms
The final step in modelling income is to convert an income quantile into actual income for a given financial year. This is achieved by matching the simulated income quantile to historic income quantile distributions. There are different distributions by:
Course Level: Level 4+, Level 3
Gender: male or female
Age: single year of age
Years since left learning bands: 1-3 years; 4-10 years; 11+ years
Income distributions in the first 3 years post training are constructed using actual ALL learner earnings from Longitudinal Education Outcomes (LEO) data. For the years 4-10 post training, we also use LEO data, but use a proxy group of learners who started before the introduction of ALLs that have similar characteristics to those that now on ALL courses. Beyond 10 years post training, we use 14 years of the Annual Population Survey (APS). Income is inflated for future growth using OBR projections of average earnings growth for the entire working population. It is also assumed that average earnings growth is even across all quantiles.
The use of LEO data is a change to the methodology relative to the 2018-19 publication. Previously only APS data was used to inform the model income forecasts, as this was the best source available at the time. It was not possible to isolate ALL-funded students in the APS data. That led to overstating the incomes of the students. Changing to LEO data has lowered the income forecasts for the ALL-funded students, meaning fewer students will reach the repayment threshold. This has led to an increased RAB and an increased transfer proportion.
5. Life events
From the time a borrower takes out a loan there are additional events that need to be factored into the modelling, such as mortality, migration, and repayments made directly to SLC. All are modelled at the individual level, but to varying levels of detail.
5.1 Mortality
The Office for National Statistics (ONS) England & Wales population projections include assumptions on mortality rates by gender and single year of age up to 2084. These are used directly to estimate the chance of death for a borrower in any year post taking out a loan, with the key assumption that ALLs borrowers have the same mortality rates as the rest of the population.
It is likely there is some difference in mortality rates for this group compared to the whole of England & Wales, particularly as there is a known link between increased wealth and improved mortality. However, any difference will be minimal and the mortality rates for the working age population are generally very low, further reducing any possible impact.
5.2 Migration
The migration assumptions are split into two components
Probability of migrating out of the country (out-migrant rate)
Length of spell out of the country: 3 years, 7 years or 20 years
Out-migrant rates by gender and age are derived by combining Office for National Statistics (ONS) out-migrant estimates with population projections. These are used directly to provide each borrower with a probability of becoming an out-migrant each year.
Once an out-migrant is identified the model assigns a length of stay for the duration abroad. The length and probability of duration are estimated from International Passenger Survey (IPS) data between 1978 and 2012, over which time actual length of stay figures have been relatively stable.
5.3 Permanently unfit for work
The model uses expected flows into the Support Group of Employment Support Allowance (ESA) as a proxy for the number of people expected to become unfit for work each year. Once identified as unfit for work, a simulated borrower has their remaining loan amount written off.
The ESA Support Group is not a perfect measure of the unfit for work rate, as it is a State Benefit that needs to be actively claimed so is not received by everyone that is eligible. It does, however, provide the closest match in definition to unfit for work which is sufficient for the relatively low number of people that will be affected.
5.4 Extending working lives
State Pension Age (SPA) is due to rise to 67 for men and women by 2024. For women this represents an additional 7 years of work before they will receive their State retirement benefits compared to the observed population in the model data sources.
The model includes a timetable to assign each borrower a State Pension age, from which there is an assumption around what employment rates and income to use given to reflect that people are likely to work for longer. For example, a man with SPA of 65 has the employment rate of a 66-year-old when aged 66, but a man with SPA of 66 has the employment rate of a 65-year-old when aged 66. This assumes that for men, the employment rate and income of a 65 year old is held constant between the ages of 65 and the new State Pension age; for women the employment rate and income of a 60 year old is held constant between the ages of 60 and the new State Pension age.
The effects of retirement can be seen in LFS data from as early as age 50, however, given the high uncertainty about how people will respond to the rises in State Pension age, and future employment in general, the model uses the simplified assumption.
5.5 Voluntary Repayments
A borrower may make voluntary repayments in addition to the repayments collected via the UK tax system, The model assumes that each borrower will make an additional yearly voluntary payment. The size of the repayments is based on historic data and depends on the outstanding debt and the number of years in the repayment period.
Data quality
Forecasting repayments are inherently uncertain and relies on the data sources, modelling techniques and assumptions. Specifically, the model assumes the characteristics of future borrowers will be the similar as historic ones derived from SLC administrative data.
Both administrative and survey data are used to inform the assumptions underpinning the ALLs model. SLC administrative data are used to determine borrowers' characteristics and loan amounts. Historic SLC data should be broadly accurate.
The Labour Force Survey (LFS) is used to determine employment and income state movements of ALLs borrowers and the Annual Population Survey (APS) and Longitudinal Education Outcomes (LEO) are used for the income distributions. The LFS is a survey of the employment circumstances of the UK population. It is the largest household survey in the UK and provides the official measures of employment and unemployment. The APS is a supplement to the LFS data. The APS is published quarterly, and each dataset contains 12 months of data. The sample size for each dataset is approximately 170,000 households and 360,000 individuals. LEO brings together information from the Department for Education with employment, benefits and earnings information from the Department for Work and Pensions and Her Majesty’s Revenue and Customs.
The employment and income status assumptions are two of the most important assumptions within the model. We derive both of those from the LFS assuming that Further Education achievers in the LFS data are representative of ALLs borrowers.
The LFS data has various limitations and a key drawback is that only one year of earnings history is available. The key assumptions arising from the data limitations are listed below:
The model 'forgets' a borrower’s past history of employment statuses prior to the current year, since a one-step transition approach is used. This means that a learner who has been unemployed for 10 years has equal chance of employment as someone who has been unemployed for just one year.
Transitions between employment states for the employed are used as a proxy for self-employed people. Self-employed people are assumed to have the same income distribution as employed learners.
We assume that a borrower who has left the labour market will return to work at the same position on the income distribution as they were in their most recent employment spell.
Despite these limitations, the LFS is the only data source currently available that has a sufficiently large sample to allow analysis of income by age and type of qualifications and transitions in and out of employment. We now have some actual repayment data from the Longitudinal Education Outcomes, but only for a limited number of years. We will seek to use this data alongside the LFS data to improve these assumptions.
The model is also dependent on the OBR macroeconomic forecasts that it uses to uprate earnings, calculate interest rates and repayment thresholds, and to discount future repayments to present values. Any significant changes to the economy from these forecasts could affect the repayments that will be made on the Advanced Learner Loans.
These forecasts show how much Government outlay on student loans is expected to be in future, how much is expected to be repaid and how the student loan book may grow in the future. The Department for Education uses these models for financial planning and in the development of student funding policies.
These forecasts are also used in the Department for Education’s annual accounts in the valuation of the student loan book and in the public sector finance statistics. The stock charge, RAB charge and transfer proportion are used to impair the face value of the loan books and the value of new loans being issued respectively, to reflect that the value of the future repayments that will be received in relation to these loans is less than the long term cost of Government borrowing that would be necessary to cover its outlay on student loans.
These models are used by the Office for Budget Responsibility as part of its estimates of public sector borrowing, including in its Economic and Fiscal Outlook that presents economic forecasts five years into the future and its Fiscal Sustainability Report that presents long term projections of UK public finances.
The year from 1 August to 31 July. Throughout the publication this is denoted in the format ‘2012/13’ to describe the year from 1 August 2012 to 31 July 2013.
Advanced Learner Loan (ALL)
A fee loan payable to Further Education (FE) providers on behalf of FE learners who meet the eligibility criteria and started a FE course on or after 1 August 2013.
Cancelled loans
The borrower no longer has any liability to repay, as provided for in the loan’s regulations. A borrower’s liability is cancelled:
On the death of the borrower;
On reaching the age or length of time cancellation criteria for their loan (which varies by loan product); or,
If borrower is in receipt of a disability related benefit and permanently unfit for work.
Capitalised interest
The interest accrued on student loans is added to a borrower’s loan balance, rather than requiring repayment at the time it is accrued.
Doctoral loan
Loans issued to students on Doctoral courses, on the Plan 3 repayment system. They are paid directly to students and can be used to cover fees or living costs.
Domicile
The usual residence of a student in the period prior to commencement of study. The financial support available to students from Government can vary for students from different domiciles. This publication includes forecasts of entrant numbers for English and EU domiciled students. Wherever ‘EU domiciled’ students are referred to this includes students domiciled in countries other than the UK that count as EU domiciled for funding purposes.
Entrants
Students in their first year of study. Defined as those starting a course in the academic year who have not been active at the same broad level of study at the same provider in either of the two previous academic years.
Face value of loan book
The total outstanding balance of the loan book. This will include all previous loan outlay and accrued interest, less any repayments or loan cancellations.
Financial year
The year from 1 April to 31 March. Throughout the publication this is denoted in the format ‘2012-13’ to describe the year from 1 April 2012 to 31 March 2013.
Some aspects of the student loan system are based on tax years (the 12-month period starting on 6 April), but as a simplification the student loan models assume that this is the same as the equivalent financial year.
Fully repaid loan
The borrower has repaid the loan in full during their repayment term without it being cancelled.
Higher education full-time loan
Loans available to students on full-time higher education courses, including first degrees, sub-degrees and certain postgraduate courses (e.g. Postgraduate Certificate in Education or PGCEs) that are eligible for the undergraduate loan system
Higher education part-time loan
Loans available to students on part-time higher education courses with an intensity of 25% or higher.
Household Residual Income
The household gross income minus payments to private pension schemes, additional voluntary contributions and employment related costs as well as allowances for dependants and students.
Income Contingent Repayment (ICR) loan
Loans for which the required repayments are based on the borrower’s income. The type of student loan that has been available to students since 1998.
Liable to make repayments
The borrower has a remaining loan balance and has reached their Statutory Repayment Due Date (SRDD).
Maintenance loan
Maintenance loans are loans to cover living costs, paid directly to the student.
Master’s loan
Loans issued to students on Master’s courses, on the Plan 3 repayment system. They are paid directly to students and can be used to cover fees or living costs.
Plans 1, 2, 3 and 5
The ICR loan scheme has been separated into different repayment arrangements called Plans 1, 2, 3 and 5. While they operate in a similar manner, they differ in some ways such as the repayment thresholds, interest rates and the length of borrowers’ repayment terms.
Plan 1 is the loan system for undergraduate students that started courses before September 2012. Plan 2 the system for undergraduates and for Advanced Learner Loans between September 2012 and September 2023. Plan 3 the system for postgraduate loans introduced in 2016. Plan 5 the system for undergraduates and for Advanced Learner Loans since September 2023.
Resource Account Budgeting (RAB) charge
Used in the DfE annual accounts, this is the proportion of loan outlay that is expected to not be repaid when future repayments are valued in present terms.
Repayment term
The period for which a loan borrower is liable to make repayments based on their income. At the end of a borrowers’ repayment term any remaining loan balance is cancelled.
Repayment threshold
The annual income threshold above which borrowers are required to make repayments on any eligible income. Plan 1, Plan 2 and Plan 5 loan borrowers are required to pay 9% of any earnings above the threshold and Plan 3 borrowers will be required to repay 6%.
Statutory Repayment Due Date (SRDD)
The point a borrower becomes liable to begin repaying a loan, normally the start of the tax year (6 April) after graduating or otherwise leaving their course. After their SRDD, borrowers are required to make repayments if their income is above the repayment threshold.
Stock charge
Used in the DfE annual accounts, this is the proportion of the total outstanding face value of the loan book that is expected to not be repaid when future repayments are valued in present terms.
Tax year
The 12-month period starting on 6 April. As a simplification, the student loan models assume that this is the same as the equivalent financial year running for 12 months from 1 April. Repayment thresholds are fixed for the duration of each tax year and borrowers’ SRDDs are at the start of the tax year after they graduate or otherwise leave their course.
Transfer proportion
Under the partitioned loan transfer approach, student loan outlay is partitioned into loaned and transferred funds. Conceptually the transfer proportion is the fraction of student loan outlay identified at loan inception as government expenditure, in recognition that this portion of the loan is unlikely to be repaid.
Tuition fee loan
Tuition fee loans are loans to cover all or part of the cost of tuition. They are paid directly to the learning provider.
Voluntary repayment
A borrower can at any time choose to repay some or all of their loan balance early, in addition to any repayments they are liable to make based on their income.
