  • Annual salary is divided into 12 equal monthly payments. Weekly estimates assume 52 equal payments; the monthly average is not a monthly payslip calculation.
  • Only the lowest threshold among selected Plans 1, 2, 4 and 5 is used. Postgraduate deductions are added separately.
  • Assumes repayments are due throughout 2026/27 and enough loan balance remains. Bonuses, variable pay, protected earnings orders, overseas repayments and Self Assessment are outside this estimate. Interest is not calculated.

This is a general estimate for information only, not tax, legal or financial advice. Real rules have more conditions than a calculator can show, so check the official source below or a qualified professional for your situation.

How it works

HMRC sets annual thresholds of £26,900 for Plan 1, £29,385 for Plan 2, £33,795 for Plan 4, £25,000 for Plan 5 and £21,000 for Postgraduate Loans. Plans 1, 2, 4 and 5 use 9%; the Postgraduate Loan repayment plan uses 6%.

Period threshold = annual threshold ÷ pay periods, rounded down to pennies Deduction = max(0, period pay − period threshold) × rate, rounded down to whole pounds

Annual salary means 12 equal monthly payments here. Weekly pay uses 52 periods. Each loan deduction is rounded separately, then added. No other intermediate rounding is applied; displayed currency uses two decimals. The yearly estimate repeats the same deduction each period. This is a payroll estimate, not a Self Assessment calculation.

Worked examples

Plan 2 plus postgraduate: £30,000 salary

Monthly pay is £2,500. Plan 2 uses £2,448.75: £51.25 × 9% = £4.6125, rounded down to £4. Postgraduate uses £1,750: £750 × 6% = £45. Together that is £49 per month and £588 per year.

Plan 5: £600 per week

The weekly threshold is £480.76. (£600 − £480.76) × 9% = £10.7316, giving £10 per week, £520 across 52 weeks and a £43.33 monthly average.

Plans 1 and 2: £3,200 per month

Use only the lower Plan 1 threshold, £2,241.66. £958.34 × 9% rounds down to £86 per month and £1,032 per year. Do not add a second deduction for Plans 1, 2, 4 and 5.

Frequently asked questions

Does every postgraduate course use the Postgraduate Loan repayment plan?
No. Postgraduate borrowing through SAAS uses Plan 4; through Student Finance Northern Ireland it uses Plan 1. The separate Postgraduate Loan repayment plan covers eligible master’s and doctoral borrowing through Student Finance England or Wales. Check your repayment plan on GOV.UK.
Can the Postgraduate Loan repayment plan run alongside Plans 1, 2, 4 and 5?
Yes. Its deduction is calculated separately and added to the single deduction for Plans 1, 2, 4 and 5. If you hold several of those plans, use their lowest threshold.
When did Plan 5 payroll repayments start?
Plan 5 entered payroll collection from 6 April 2026. Select it only if your repayments are due; the calculator does not determine your personal repayment start date.
Why can a bonus change my repayment?
PAYE checks earnings each pay period. A bonus can put that period above the threshold even if your annual income is lower. GOV.UK says you can request a refund after the tax year if annual income is below your plan’s annual threshold.
Can I combine income from two jobs?
For ordinary payroll deductions, calculate each employment separately. Self Assessment can instead consider combined annual income and is outside this tool.
Does this estimate interest or when my loan is paid off?
No. It estimates income-based payroll deductions only, without loan balances, interest or write-off dates.
