How this is worked out
Student-loan repayments are 9% of income above the Plan 4 threshold, not a percentage of your whole salary. On £37,000: £37,000 − £32,745 = £4,255 above the threshold; 9% of £4,255 = £382.95 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 4 with steady annual earnings of £37,000 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.
