Student loan repayment calculator

Plans 1, 2, 4 and 5 deduct 9% of earnings above their annual thresholds: £26,900, £29,385, £33,795 and £25,000 respectively. A postgraduate loan adds 6% above £21,000. Undergraduate and postgraduate deductions can apply together.

This estimates deductions from employment earnings, not the cost of repaying a loan in full. Payroll calculates deductions each pay period and rounds down to whole pounds. Bonuses and uneven pay can therefore produce different totals. Interest, outstanding balances and write-off dates are not modelled.

On £30,000 with Plan 2, annual repayments are (£30,000 − £29,385) × 9% = £55.35. A postgraduate loan adds (£30,000 − £21,000) × 6% = £540, for a combined annual estimate of £595.35.
