How much will I repay on a Plan 5 student loan?

Plan 5 applies to eligible new undergraduate borrowers in England from August 2023. You repay 9% of earnings above £25,000 a year. Interest is linked to RPI. The current write-off period is 40 years. On a £35,000 salary, the annual formula estimates a monthly repayment of about £75.

🆕 What's different about Plan 5?

  • ✓ Lower threshold (£25,000 vs £29,385 for Plan 2) — repayments start sooner
  • ✓ Lower interest (RPI only, not RPI+3%) — your balance grows slower
  • ✓ Longer write-off period (40 years vs 30 years on Plan 2)

  • Who this applies to: Students starting an undergraduate course in England from September 2023
  • Repayment rate: 9% of earnings above the threshold
  • Key difference: Interest is linked to RPI only — unlike Plan 2 where it can be up to RPI + 3%
  • Write-off: Remaining balance written off after 40 years under current terms
  • Example: If you earn £35,000 a year, your monthly repayment would be approximately £75

Plan 5 vs Plan 2: Which is better?

The answer depends on your earnings and whether you'll pay off the loan in full:

  • High earners who will pay off in full: Plan 5 is often better due to lower interest
  • Average earners likely to have debt written off: Plan 2 might be better due to higher threshold (you keep more of your salary)
  • The trade-off: Plan 5 has lower interest but you start repaying sooner and for longer

Plan 5 Student Loan: Common Questions

What is a Plan 5 student loan?
Plan 5 applies to eligible new undergraduate borrowers in England from August 2023. It has an RPI-linked interest formula, a £25,000 annual threshold for the current tax year, and a 40-year write-off period under current terms.
Is Plan 5 better or worse than Plan 2?
The total amount repaid depends on the plan terms, balance, and your income over time. Plan 5 has a lower threshold (£25,000 compared with £29,385 for Plan 2) and a longer write-off period (40 years compared with 30). Compare scenarios for the same income assumptions.
When will my Plan 5 loan be written off?
Any remaining Plan 5 balance is written off after 40 years under current terms. Confirm when the period starts for your loan in your terms or SLC account.
How much will I repay per month on Plan 5?
You repay 9% of earnings above £25,000 a year. If you earn £30,000 or £40,000 a year, the estimated monthly repayments are about £38 or £113. Actual PAYE deductions use pay-period thresholds. Below the applicable period threshold, no Plan 5 deduction is due.
Does Plan 5 affect postgraduate loans?
Postgraduate Loans have separate terms, with a 6% repayment rate above £21,000. If you hold both, the deductions are calculated separately and collected together through payroll when due.
