The same £90,000 on every plan

If you were on a different plan, the repayment on £90,000 in 2025/26 would be:

Plan	Threshold	Rate	Per year	Per month
Plan 5 (this page)	£25,000	9%	£5,850.00	£487.50
Plan 1	£26,065	9%	£5,754.15	£479.51
Plan 2	£28,470	9%	£5,537.70	£461.47
Plan 4	£32,745	9%	£5,152.95	£429.41
Postgraduate Loan	£21,000	6%	£4,140.00	£345.00

Lower thresholds mean repayments start sooner; the rate is 9% for all undergraduate plans and 6% for the Postgraduate Loan.

How this is worked out

Student-loan repayments are 9% of income above the Plan 5 threshold, not a percentage of your whole salary. On £90,000: £90,000 − £25,000 = £65,000 above the threshold; 9% of £65,000 = £5,850.00 a year. Employed borrowers pay this through PAYE; SLC rounds each pay-period deduction down to the nearest pound. Interest is added to the balance separately and does not change the deduction.

Assumptions

A 2025/26 planning estimate for a borrower on Plan 5 with steady annual earnings of £90,000 and no in-year bonus spikes. It does not model the per-pay-period rounding, interest, or any voluntary overpayments. Your SLC account and payslip are the authority.
