How UK Student Loan Repayment Works in 2026
Student loans in England, Wales, Scotland, and Northern Ireland operate under different repayment plans. Your monthly repayment depends on your income before tax, not your total debt. You repay 9% of income above the threshold for undergraduate plans (Plan 1/2/4) or 6% above the Postgraduate Loan threshold. The government writes off any remaining balance after a set period (usually 30 years for Plan 2, 40 years for Plan 4 and older plans).
Our student debt payment calculator uses official 2026 thresholds and interest estimates to help you understand your monthly obligations and how long it might take to clear your student loan.
UK Plan Thresholds & Interest Rates (2026-27)
| Plan | Repayment threshold (yearly) | Repayment % above threshold | Typical interest rate (2026) |
|---|---|---|---|
| Plan 1 | £22,015 | 9% | RPI (4.3%) |
| Plan 2 | £27,295 | 9% | RPI + up to 3% (income contingent) |
| Plan 4 | £27,660 | 9% | RPI (4.3% – 2026 estimate) |
| Postgraduate Loan | £21,000 | 6% | RPI + 3% (approx 6.0%) |
Exclusive insight: Unlike consumer debt, student loan repayments are automatically deducted from your salary (PAYE). If your income drops below the threshold, payments stop — no penalties. Use our tool to see how career changes impact your cash flow.

5-Point Checklist: Optimise Your Student Debt Strategy
- Know your plan type: Check your student finance letters. Mix-ups between Plan 2 and Plan 4 can change repayment dramatically.
- Use the student debt monthly payment calculator before accepting a job offer — it reveals true take-home impact.
- Consider voluntary repayments only if: You are a high earner (over £70k) and expect to fully repay before write-off; otherwise it’s often not cost-effective.
- Account for interest: Plan 2 interest can reach 7.3% if you earn £49k+; our calculator includes average interest to forecast payoff.
- Update after salary changes: Every raise triggers higher monthly deduction. Recalculate to avoid surprises.
Original insight: 2026 sees the student loan repayment thresholds rising modestly with inflation, but Plan 2 interest remains high. For graduates with starting salaries £28k-£35k, monthly repayments often feel manageable, yet total interest may grow — but balances are wiped after 30 years anyway, so treat it like a "graduate tax".
How to Use This Student Loan Debt Payment Calculator
- Select your UK loan plan (Plan 1, Plan 2, Plan 4, or Postgraduate).
- Enter your annual gross salary before tax.
- Input your current outstanding student loan balance (from SLC statement).
- View your monthly payment, yearly repayment, and estimated payoff timeline based on your income & projected interest.
The calculator also estimates time to repay: if your annual repayments exceed the interest accrued each year, the balance decreases; otherwise it might be written off at the end of the term (Plan 2: 30 years from April after graduation).
Should You Make Extra Repayments?
Because UK student loans are not standard debt, overpaying is rarely beneficial unless you’re a very high earner. Using our student debt payment calculator, you can test: if your projected total repayment (before write-off) exceeds your current balance, it may be worth clearing early. However, for most graduates, the loan is better treated as a progressive tax. 2026 rule: If you live abroad, thresholds differ — contact SLC for overseas repayment schedules.
