The same £40,000 on every plan
If you were on a different plan, the repayment on £40,000 in 2025/26 would be:
| Plan | Threshold | Rate | Per year | Per month |
|---|---|---|---|---|
| Plan 5 (this page) | £25,000 | 9% | £1,350.00 | £112.50 |
| Plan 1 | £26,065 | 9% | £1,254.15 | £104.51 |

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 £40,000: £40,000 − £25,000 = £15,000 above the threshold; 9% of £15,000 = £1,350.00 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 £40,000 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.
