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.

How to use this tool

  1. Enter your gross annual income used for student loan purposes.
  2. Select your loan plan (check your SLC account or plan letter if unsure).
  3. Optionally tick postgraduate loan if you repay both.
  4. Review estimated monthly, weekly and annual deductions.
  5. Copy the summary or combine with the take-home pay calculator for net pay after loans.

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.

Frequently asked questions

Which plan am I on?
Check your Student Loans Company account or paperwork. Plan 2 is common for English undergraduates who started from 2012; Plan 5 applies to many newer starters; Plan 4 is Scottish; Plan 1 is older loans. Your employer’s payroll may also show a plan number.

Is interest included?
No. This estimates the income-contingent deduction only, not interest added to the balance or time to clear the loan.
Can I model two loans?
Yes. Select your undergraduate plan and enable the postgraduate option to add a 6% postgraduate-style deduction above the PG threshold.
Does this affect my tax calculation?
Student loan is separate from Income Tax and NI. Use our take-home pay calculator for tax/NI, then subtract this loan estimate for a combined view.
