UK Student Loan Repayment Calculator

How income-contingent repayments work

UK student-loan repayments are based on your income, not a fixed monthly instalment. You normally repay a percentage of your earnings above the threshold for your repayment plan, and nothing on the income below it. If you earn less than the threshold, no repayment is due for that period.

Select one undergraduate plan and, if it applies, a Postgraduate Loan. The calculator shows the estimated Student Loan deduction, the Postgraduate Loan deduction and the total repayment for the pay period you choose. It uses the 2026–27 repayment thresholds and rates — always check your payslip and official guidance for your actual deduction.

A Student Loan deduction is taken from your pay alongside Income Tax and National Insurance. For the full picture, see the UK Take-Home Pay Calculator. Outside the UK, see the US Student Loan Payoff Calculator.

How to use this calculator

1. Choose whether your income is paid annually, monthly or weekly.
2. Enter your gross income for that period — the figure before Income Tax, National Insurance and pension contributions.
3. Pick your undergraduate plan: Plan 1, Plan 2, Plan 4 or Plan 5, or None.
4. Choose Yes if you also repay a Postgraduate Loan.

The estimated repayment and the plan-by-plan breakdown update as you type. Monthly and weekly figures are illustrations based on the same pay throughout the year; your employer works out the real deduction each pay period.

What do I need to enter?

• How is your income paid? — Annual, Monthly or Weekly. It picks which official threshold is used, and changing it does not convert your income figure.
• Gross income for that period — pay before Income Tax, National Insurance and pension deductions, from 0 to 10,000,000, for the period you chose.
• Undergraduate Student Loan plan — None, Plan 1, Plan 2, Plan 4 or Plan 5. Each plan has its own threshold; every undergraduate plan repays at 9%.
• Do you also repay a Postgraduate Loan? — Yes adds a separate 6% repayment above the Postgraduate Loan threshold, on top of any undergraduate plan.

What do the results show?

• Estimated student-loan repayment — the total for the pay period you chose.
• Undergraduate Student Loan and Postgraduate Loan — each deduction on its own, or Not selected.
• Repayment this year — the total for the year; on monthly or weekly income it is labelled Annual repayment (illustration).
• Share of gross income — the repayment as a percentage of the income you entered.
• Summary tab — the threshold, income above it and rate for each plan.

How is a student loan repayment calculated?

The calculator subtracts the repayment threshold for your plan and pay period from the gross income you enter. If the result is positive, it applies the repayment rate for that plan. If you select both an undergraduate plan and a Postgraduate Loan, it repeats the calculation separately for each and adds the two estimates together — an undergraduate repayment is never subtracted from your income before the Postgraduate Loan is worked out.

Worked example: £40,000 a year on Plan 2 with a Postgraduate Loan. The Plan 2 threshold is £29,385, so £10,615 is above it and the undergraduate repayment is 9% of that, or £955.35 a year. The Postgraduate Loan threshold is £21,000, so £19,000 is above it and that repayment is 6%, or £1,140.00 a year. The total estimated repayment is £2,095.35 a year, about £174.61 a month.

2026–27 thresholds and rates

Payroll uses the equivalent threshold for each pay period. For 2026–27 the monthly thresholds are £2,241.66 (Plan 1), £2,448.75 (Plan 2), £2,816.25 (Plan 4), £2,083.33 (Plan 5) and £1,750.00 (Postgraduate Loan); the weekly thresholds are £517.30, £564.90, £649.90, £480.76 and £403.84 in the same order. The calculator uses these exact figures when you choose a monthly or weekly income.

Plan 2 is frozen. Most recent graduates in England are on Plan 2, and its threshold is held at £29,385 until April 2030 under the 2025 Autumn Budget rather than rising with inflation each year. In real terms that means a larger share of pay is charged over time, so a Plan 2 repayment can rise faster than earnings. The other plan thresholds are still reviewed annually.

Thresholds and rates shown are effective from 6 April 2026 for the 2026–27 tax year (6 April 2026 to 5 April 2027). They can change each year, so check official guidance for your circumstances. Rates last reviewed 10 September 2026.

What this calculator does not do

This page is a repayment-from-income estimator. It estimates the deduction taken from your earnings — not your loan balance or when the loan clears.

• This is an estimate, not an official payroll, Student Loans Company or Self Assessment calculation.
• It uses the gross income you enter for the selected annual, monthly or weekly period.
• PAYE deductions are normally worked out for each pay period, so variable pay can produce a different annual total.
• Multiple jobs, bonuses, commission, overtime, part-year work and payroll rounding can all change the actual deduction.
• Self-employed repayments are generally collected through Self Assessment rather than a payslip.
• It does not estimate loan balances, interest, repayment completion, write-off dates or whether voluntary overpayments are worthwhile.

Disclaimer and sources

This calculator provides an estimate of income-contingent Student Loan and Postgraduate Loan repayments for the 2026–27 tax year. It is not an official payroll, Student Loans Company or Self Assessment calculation, and it does not model loan balances, interest or write-off dates. Your actual deduction may differ because PAYE deductions are worked out through payroll each pay period. Check official GOV.UK guidance or speak to a qualified adviser before relying on this estimate.

Thresholds and rates are based on GOV.UK guidance for 2026–27, effective from 6 April 2026. Last reviewed 10 September 2026.
