UK Student Loan Repayment Calculator — How Much Will You Actually Pay Back?

8 min read✅ Expert reviewed

Most graduates will never fully repay their student loan. Find out exactly how much you are likely to repay based on your salary, and whether it ever makes sense to overpay.

How Much Will You Actually Repay on Your Student Loan?

The majority of UK graduates will never fully repay their student loan before it is written off. Your monthly repayment is always 9% of earnings above your plan threshold — your salary, not your balance, determines what you pay.

Monthly Repayment Examples on Plan 5

Annual SalaryMonthly Repayment
£25,000 (threshold)£0
£30,000£37.50
£35,000£75
£45,000£150
£60,000£262.50

Will You Ever Fully Pay It Off?

Research from the Institute for Fiscal Studies suggests roughly 25% of graduates under Plan 5 will repay in full. The rest will have some or all of their balance written off at the 40-year mark.

Salary Scenarios

£25,000Low growthWritten off, minimal repayment
£35,000Average growthWritten off, moderate repayment
£50,000High growthPartially repaid
£70,000+Very highLikely fully repaid

Should You Make Voluntary Overpayments?

Only if you are absolutely certain you will repay the full balance before write-off. For most graduates, that money is better directed towards an ISA, pension, or emergency fund.
