Smart Tips

Your loan is likely to be written off with £219,492 remaining

At your current salary and growth trajectory, you'll repay £49,591 over 28 years before the remaining balance is written off. This is normal — most Plan 2 and Plan 5 borrowers don't fully repay.

GOV.UK: When your loan gets written off (opens in new tab)

Making voluntary repayments may not save you money

Since your loan is projected to be written off, any extra payments just reduce the amount written off — not the amount you actually pay. Those funds might be better invested elsewhere.

GOV.UK: Repaying early (opens in new tab)

Your loan balance is currently growing

At your current salary, interest (£3,285/year) exceeds repayments (£235/year). This is common in early career — as your salary grows, repayments will increase and eventually outpace interest.

GOV.UK: Student loan interest (opens in new tab)

Student loan interest rates change periodically

The interest rate used (7.3%) is an approximation. Actual rates are updated each September based on RPI inflation and (for some plans) the Bank of England base rate. Check the Student Loans Company for your current rate.

Frequently asked questions

Will my student loan be written off?
It depends on your loan plan. Plan 2 loans are written off after 30 years. Plan 5 after 40 years. Plan 1 after 25 years. Plan 4 and Postgraduate loans after 30 years. Many borrowers on Plan 2 and Plan 5 will not fully repay before write-off.
Should I make voluntary overpayments on my student loan?
For most Plan 2 and Plan 5 borrowers whose loans are likely to be written off before full repayment, voluntary overpayments are usually not beneficial — you would be paying off an amount that would otherwise be written off. Overpaying only makes sense if you are certain you will repay in full before write-off.
What is the repayment threshold for Plan 2 student loans in 2025-26?
For Plan 2, you repay 9% of earnings above £28,470 per year. No repayments are made below this threshold. For Plan 5 the threshold is £25,000. For Plan 1 it is £26,065.
