Student Loan Repayment FAQ
Everything you need to know about how UK student loan repayments are calculated, the difference between plans, and what happens if your income changes.
Plan 1 generally applies to English and Welsh students who started before September 2012. Plan 2 applies to English and Welsh students who started between 2012 and 2023. Plan 4 applies to Scottish students. Plan 5 applies to English students who started from September 2023 onward. Postgraduate Loans apply to Master’s and Doctoral study and are repaid separately.
Undergraduate student loan repayments are calculated as 9% of your income above your plan’s repayment threshold. Postgraduate Loan repayments are calculated as 6% of your income above the postgraduate threshold. If you earn below the threshold, you make no repayments that year.
Yes. If you have both an undergraduate loan (Plan 1, 2, 4 or 5) and a Postgraduate Loan, you repay both simultaneously through separate deductions: 9% above the undergraduate threshold and 6% above the postgraduate threshold, applied independently.
No. Interest increases your total outstanding loan balance, but your monthly repayment is based purely on your income and repayment threshold, not on how much interest has accrued. Higher interest simply means it may take longer to clear the loan, or it may be written off before it is fully repaid.
Write-off periods vary by plan. Plan 1 loans are typically written off 25 years after the April you were first due to repay. Plan 2 loans are written off 30 years after the same point. Plan 4 and Plan 5 terms differ again, and Postgraduate Loans follow their own write-off rules. Check your plan’s specific terms for the exact period.
No. If your income is below your plan’s repayment threshold, no repayments are deducted that pay period. Repayments only apply to the portion of your income above the threshold, not your full salary.
