Student Loan Repayment Calculator for the UK

See what you repay each month, whether you would clear your student loan, and how much could be written off.

Figures last checked 18 October 2026

An estimate, not financial advice. Thresholds, rates and write-off rules are the figures GOV.UK shows now, checked on 18 October 2026. They change every 6 April. Nothing you enter is saved or sent anywhere.

You cannot choose your plan. Not sure which you are on? See "Which plan am I on?" below.

Include bonuses and overtime. If you are still studying, use the salary you expect when you start repaying.

Leave blank for no pay rises. Up to 30%.

Years since the April you were first due to repay. Enter 0, or leave blank, if you have not started.

Choose your plan and enter your balance and salary to see the result.

How repayments work

  • You repay 9% of your income over the threshold for Plans 1, 2, 4 and 5, and 6% for a Postgraduate Loan. Income means what you earn before tax and other deductions, including bonuses and overtime.
  • The amount you owe does not change how much you repay each year. Only your income and your plan do.
  • This year's yearly thresholds are £26,900 for Plan 1, £29,385 for Plan 2, £33,795 for Plan 4, £25,000 for Plan 5 and £21,000 for a Postgraduate Loan. They change on 6 April each year.
  • The earliest you repay is the April after you leave your course. Repayments stop if you stop working or your income goes below the threshold, but interest is still added.
  • If you have more than one plan and no Postgraduate Loan, you make one repayment of 9% of your income over the lowest of your thresholds. With a Postgraduate Loan as well, you repay 6% over the Postgraduate threshold and 9% over the lowest threshold of your other plans.

Interest

  • Plans 1, 4 and 5 are charged 4.1%, and a Postgraduate Loan 6%, at the moment.
  • Plan 2 interest depends on your income after you finish your course. It is 4.1% at or below £29,385, 6% at or above £52,885, and in between GOV.UK says it is 4.1% plus up to 1.9%. This calculator assumes it rises evenly between those incomes.

You can check your plan in your online account on GOV.UK. If it differs from the plan your employer has, show them your plan letter so they can update your payroll details.

What this calculator assumes

  • Today's thresholds and interest rates stay the same every year. In reality they change each April, so treat the result as a guide, not a forecast.
  • Interest is added monthly, and your repayment each month is your yearly salary above the threshold, multiplied by the rate and divided by 12.
  • You are on one plan. It does not combine several loans.

What it does not include

  • Several jobs, self-employment and Self Assessment. HMRC works out repayments from your tax return if you are self-employed.
  • Extra repayments. GOV.UK says there is no penalty for paying some or all of your loan off early.
  • The Welsh £1,500 Maintenance Loan write-off, living overseas, and cancellation for illness or disability.

Does a student loan affect your credit score?

GOV.UK says student loans do not appear on credit reports and do not affect your credit score. Lenders may still consider them during affordability checks for other borrowing, such as a mortgage.
