Use this calculator to estimate your monthly student loan deductions and how long is left on each loan - or when it will be written off. Add every plan you have (Plan 1, Plan 2, Plan 4, Plan 5, Postgraduate) and enter your current annual pay.
Loan types (UK):- Plan 1: older England/Wales loans (before Sep 2012) and most Northern Ireland loans.
- Plan 2: England/Wales undergrad from Sep 2012 to Jul 2023.
- Plan 4: Scotland (undergraduate and many postgraduates).
- Plan 5: England/Wales undergrad starting on or after 1 Aug 2023.
- Postgraduate (PGL): Master’s or Doctoral loans (England/Wales).
Tip: Add the “First April in repayment (YYYY)” for each plan so we can show a write-off date even if you’re under the threshold today.
How deductions are worked out
- Undergraduate loans (Plans 1/2/4/5): payroll deducts 9% of income over the lowest threshold of the plans you hold (one “Student Loan” line on your payslip).
- Postgraduate loan (PGL): taken alongside at 6% of income over the PGL threshold (separate payslip line).
- Plan 5: deductions begin from April 2026.
- PAYE rounding: each deduction is rounded down to the nearest £ every pay period — this is reflected in the monthly figures.
When loans are written off (typical)
- Plan 1: 25 years from the first April you were due to repay (older loans can be age 65).
- Plan 2: 30 years.
- Plan 4: 30 years (older Scottish loans may be earlier).
- Plan 5: 40 years.
- Postgraduate: 30 years.
