What this means
You repay 9% of everything you earn above £29,385 (Plan 2, 2026-27). A pay rise raises the amount; a bigger balance does not.
You would repay £29,218 in total, then £88,722 is cancelled in April 2052. Extra payments do not save you money unless they clear the loan before then.

Rates, assumptions and sources
Every figure below is the 2026-27 published figure, read from this site's single source of truth at page-render time[source]. The 6% Plan 2 and Postgraduate interest cap covers the 2026/27 year only and is not assumed to continue[source].
| Plan | Threshold | Rate | Interest | Written off | Threshold freeze |
|---|---|---|---|---|---|
| Plan 2 | £29,385[source] | 9% | 4.1% to 7.1% by income, capped at 6% for 2026-27[source] | 30 years[source] | Frozen at £29,385 until April 2030 |
Write-off is counted from the April after the course ends, not from the course-end date itself, and the Plan 2 interest bands (£29,385 lower, £52,885 upper) are frozen alongside the Plan 2 repayment threshold.
This calculator also assumes
- Your salary growth
- 2.5% a year
- Threshold uprating once the freeze ends
- 2.0% a year
- RPI beyond the current rate period
- 3.0% (assumption)
- Inflation used for today's-money figures
- 3.0% a year
- Plan 2: repayments start
- April 2022 (the April after the course ends)
- Plan 2: write-off
- April 2052 (30 years later)
Growth, inflation and long-run interest figures are assumptions, not published rates. Change them and the projection changes.
Important: these are estimates for illustration, based on current UK rules, your inputs and the assumptions above. Your real repayments may differ if policy, interest rates, your pay or your circumstances change. Plan 2 interest slides with income between RPI and RPI plus 3%; Plan 1, Plan 4 and Plan 5 interest does not depend on income. This is not financial advice. For your own figures, check your account with the Student Loans Company or speak to a qualified financial adviser.

How student loan repayments are worked out
You repay 9% of your income above your plan's threshold, or 6% on a Postgraduate Loan. Income means your pay before tax, including bonuses and overtime. Below the threshold you repay nothing. What you owe does not change your monthly repayment. It only changes how long you keep paying.
For example, on Plan 2 with a salary of £30,000 you repay 9% of £615, the part above £29,385. That is £55.35 a year, or about £4.61 a month.
| Plan | Who is on it | Threshold 2026-27 | You repay | Interest now | Written off |
|---|---|---|---|---|---|
| Plan 1 | England or Wales before September 2012; all Northern Ireland loans | £26,900 a year£2,241 a month | 9% above it | 4.1% | After 25 yearsor at 65 if your first loan was paid before September 2006 |
| Plan 2 | England September 2012 to July 2023; Wales from September 2012 | £29,385 a year£2,448 a month | 9% above it | 4.1% to 6%, by income | After 30 years |
| Plan 4 | Scotland | £33,795 a year£2,816 a month | 9% above it | 4.1% | After 30 yearsor at 65 if sooner, for a first loan paid before August 2007 |
| Plan 5 | England from August 2023 | £25,000 a year£2,083 a month | 9% above it | 4.1% | After 40 years |
| Postgraduate Loan (Plan 3) | Master's or Doctoral Loan from England or Wales | £21,000 a year£1,750 a month | 6% above it | 6% | After 30 years |
The write-off clock starts in the April after your course ends. The Plan 2 threshold is frozen at £29,385 until April 2030, and the Plan 5 threshold at £25,000 until April 2027. The calculator above includes both freezes. Plan 2 and Postgraduate interest is capped at 6% for 2026-27. Source: Repaying your student loan on gov.uk.

Student loan repayment questions
You repay 9% of your income above your plan's threshold, or 6% above £21,000 on a Postgraduate Loan. For 2026-27 the yearly thresholds are £26,900 for Plan 1, £29,385 for Plan 2, £33,795 for Plan 4 and £25,000 for Plan 5. On Plan 2 with a salary of £30,000, that is about £4.61 a month.
The earliest is the April after you finish or leave your course, and only if your income is over your plan's threshold. If you earn less than the threshold, nothing is taken.
No. Your monthly repayment depends only on your income. Your balance decides how long you keep paying, and whether you clear the loan before it is written off.
It depends on your plan, counted from the April you were first due to repay. Plan 1 is written off after 25 years (or at 65 if your first loan was paid before September 2006). Plan 2 and Plan 4 are written off after 30 years (some older Scottish loans end sooner, at 65), Plan 5 after 40 years, and a Postgraduate Loan after 30 years.
Right now Plan 1, Plan 4 and Plan 5 are charged 4.1%. Plan 2 is charged 4.1% to 6% depending on your income, and a Postgraduate Loan 6%, both under a 6% cap. Interest is added even when you earn below the threshold.
You repay both at the same time: 6% of your income above £21,000 for the Postgraduate Loan, plus 9% above your undergraduate plan's threshold. Tick "I also have a Postgraduate Loan" in the calculator to see both.
Only if you expect to clear the loan before it is written off. If it will be written off anyway, extra payments add to what you pay rather than saving you money, and you cannot get them refunded. Enter an extra monthly payment in the calculator to compare the two.
Student loans do not appear on credit reports and do not affect your credit score. Lenders may still count your repayments when they check what you can afford, for example for a mortgage.
HMRC works out what you owe from your Self Assessment tax return, and you pay it at the same time as your tax.
Tell the Student Loans Company if you leave the UK for more than 3 months. You keep repaying, using a threshold set for the country you live in, unless you can show your income is below it.
It uses the published 2026-27 thresholds and interest rates, and the announced Plan 2 and Plan 5 threshold freezes. Anything further ahead, such as your pay rises and future RPI, is an assumption you can change under More settings. Treat the results as estimates, not financial advice.
If terms like RPI, threshold or write-off are unfamiliar, our student loan glossary explains them in plain English. More answers are on the student loan FAQs page.
