UK Student Loan Repayment Calculator
UK student loans are usually repaid as a percentage of income above a plan-specific threshold — not like a fixed personal loan instalment. Knowing the monthly deduction helps when comparing salaries or budgeting after graduation.
This free calculator estimates repayments for Plan 1, Plan 2, Plan 4 (Scotland), Plan 5 and postgraduate loans using illustrative 2026/27 tax year thresholds. You can also stack a postgraduate loan on top of an undergraduate plan.
It does not track your remaining balance, interest rate on the loan, or write-off date. Confirm your plan type and thresholds with the Student Loans Company and your payslip.

- Select your loan plan (check your SLC account or plan letter if unsure).

- Review estimated monthly, weekly and annual deductions.

How UK student loan repayments work
For most undergraduate plans you repay 9% of income above the annual threshold for your plan. Postgraduate loans typically repay 6% above a separate (usually lower) threshold. If you have both, both deductions can apply.
Illustrative 2026/27 thresholds used here: Plan 1 £26,900; Plan 2 £29,385; Plan 4 £33,795; Plan 5 £25,000; postgraduate £21,000. Thresholds are updated by government and can freeze or rise with inflation depending on policy.
Employers deduct student loans through PAYE when notified. Self-employed borrowers usually settle via Self Assessment. Overseas rules and voluntary repayments differ — this tool is for a simple UK income-based estimate only.
