What this repayment estimate shows
This page estimates income-based student loan deductions using the repayment thresholds and rates for the selected plan. It is useful for checking a payslip, planning a salary change, or estimating the effect of bonus income.
- IncomeEnter annual income before student loan deductions. The calculator adds the bonus field before applying the threshold.
- Plan choiceSelect the plan that applies to your loan. If you are not sure, check your Student Loans Company account, payslip, or student finance records.
- Postgraduate loanIf you repay an undergraduate plan and a postgraduate loan at the same time, the calculator adds the postgraduate deduction separately.
- Payroll timingThe annual, monthly, and weekly numbers are smoothed estimates. Actual payroll deductions can vary if your income changes during the year.
Worked example
For Plan 2 with £35,000 annual income and no bonus, the 2026/27 threshold used here is £29,385. The amount above the threshold is £5,615. At 9%, the estimated annual repayment is about £505, or about £42 per month.
Does this calculate student loan interest?
No. It estimates repayments deducted from income. Interest, balance growth, write-off dates, and voluntary repayment decisions need a separate balance-based calculation.
Why are monthly payslip deductions sometimes different?
Payroll can assess income by pay period, and bonuses or irregular earnings can affect individual payslips. This page smooths the annual estimate into monthly and weekly figures.
Can I repay an undergraduate and postgraduate loan together?
Yes, some borrowers repay both. In that case, undergraduate plan repayments and postgraduate repayments are calculated separately and added together.
