- Employees with both undergraduate and postgraduate student loans assessing combined deductions
- Mortgage applicants calculating how student loan deductions reduce lender affordability multiples
How UK Student Loan Repayments Work
UK student loans do not operate like typical bank loans or commercial debt. Monthly repayments are linked entirely to how much you earn, not the size of your outstanding loan balance. You only repay 9% of your gross earnings above your specific plan’s annual threshold.
If your income falls below the statutory threshold due to career breaks, parental leave, or job changes, repayments stop immediately with no arrears or penalties.
Plan 2 vs. Plan 5: The 30 vs 40-Year Write-Off Rule
Under Plan 2 (students who started between September 2012 and July 2023), any remaining balance is cancelled and written off completely after 30 years from the April after graduation. For Plan 5 students (starting August 2023 onwards), the repayment threshold is lower (£25,000) and the write-off term is extended to 40 years.
Because the vast majority of Plan 2 graduates never repay their full balance before the 30-year write-off, making voluntary overpayments is mathematically unnecessary for most workers.
