About the UK Student Loan Repayment Calculator
UK student loan repayments are 9% of income above your plan's threshold (6% for Postgraduate Loans), taken through payroll or self-assessment. The amount you owe doesn't change your repayment, and any balance left is written off after a set period, so many graduates never repay in full.
The formula
Repayment = rate × (income − threshold)
Thresholds 2026/27
| Plan | Yearly threshold | Rate |
|---|---|---|
| Plan 1 | £26,900 | 9% |
| Plan 2 | £29,385 | 9% |
| Plan 4 (Scotland) | £33,795 | 9% |
| Plan 5 | £25,000 | 9% |
| Postgraduate Loan | £21,000 | 6% |

Questions people ask
Should I overpay?
Only if you expect to repay in full before write-off; otherwise overpaying may not save money.
Is the loan written off?
Yes. Any balance left is cancelled after a set time: 30 years after you're first due to repay for Plan 2 and Plan 4 loans, and 40 years for Plan 5. Plan 1 depends on when the loan was taken out.
