How this is worked out
Student-loan repayments are 6% of income above the Postgraduate Loan threshold, not a percentage of your whole salary. On £55,000: £55,000 − £21,000 = £34,000 above the threshold; 6% of £34,000 = £2,040.00 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 Postgraduate Loan with steady annual earnings of £55,000 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.
