Student Loan Repayment Planner

Estimate repayments on UK income-contingent student loans. See what you might pay each month, how much you could repay over your lifetime, and whether your balance is likely to be written off.

How UK student loans work

Repayments depend on your income, not how much you borrowed. You pay a percentage of earnings above your plan threshold. Any remaining balance is written off after a set period — so for many graduates the loan behaves like a time-limited graduate tax rather than traditional debt. Not sure which plan you're on? Match your course start date and location below, or check your Student Loans Company account.

Plan 1

Who it's for: Undergrad, older England/Wales or Northern Ireland

Written off after 25 years (or at 65 for very old loans — check your SLC account).

Plan 2

Who it's for: Undergrad England/Wales, Sep 2012 – Jul 2023

Variable interest by income. Written off after 30 years.

Plan 4

Who it's for: Scotland

Written off after 30 years.

Plan 5

Who it's for: Undergrad England/Wales from Aug 2023

Lower threshold. Written off after 40 years. Repayments from April 2026.

Plan 3 (Postgraduate)

Who it's for: Postgraduate (Master's / Doctoral)

Separate from undergraduate. 6% above its own threshold. Written off after 30 years.

Multiple loans

Undergraduate plans share one 9% deduction above the lowest threshold. Postgraduate is an additional 6% on its threshold.

Voluntary overpayments reduce your balance but may not reduce lifetime cost if you were already likely to reach write-off before clearing the debt — especially on Plan 2.

For credit cards and personal loans, use the Debt Payoff Planner. For net pay after tax, see the Take-Home Salary Calculator.
