- 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.
