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: payroll deductions apply from 6 April 2026 using the £25,000 annual threshold.
  • 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.
What should you do with this information?

Student loans behave more like a graduate tax for many people. You may want to see how deductions affect your take-home pay or compare scenarios as your salary changes.
