UK Student Loan Repayment Calculator
Student loans are repaid through the tax system: you repay 9% of everything you earn over your plan’s threshold (6% for postgraduate loans), whether you are employed or self-employed.
Choose your plan and enter your income to see your annual, monthly and weekly repayments.
How the calculation works
We believe numbers should be transparent. Here is the formula behind this calculator.
Worked example
Worked example: £35,000 salary on Plan 2 in 2026/27
Important assumptions
- Repayments are 9% of income above your plan threshold (6% for postgraduate loans).
- Thresholds rise each April — this calculator uses the threshold for the selected tax year.
- Repayments are taken from all income above the threshold, so income from multiple jobs is combined by HMRC.
- The calculator shows annual repayments and does not model interest, early payoff or the 30-year write-off.
Frequently asked questions
Which student loan plan am I on?
Plan 1: courses started before September 2012. Plan 2: 2012 to 2023. Plan 4: Scottish borrowers. Plan 5: courses starting after August 2023. Postgraduate loans are separate and repaid at 6%.
Do I start repaying if my income drops below the threshold?
No. You only repay when your income is above your plan’s threshold, and repayments pause automatically if your income falls below it.
What happens if I never pay it off?
Any balance left after the loan’s write-off point is cancelled — typically 30 years after you become eligible to repay (40 years for Plan 5). The exact rules depend on your plan.
