How this is worked out
Student-loan repayments are 9% of income above the Plan 1 threshold, not a percentage of your whole salary. On £45,000: £45,000 − £26,065 = £18,935 above the threshold; 9% of £18,935 = £1,704.15 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 1 with steady annual earnings of £45,000 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.
