Add a monthly overpayment below and watch what it does to your balance, your payoff date, and the total you hand over. For a lot of borrowers the answer is uncomfortable: the overpayment changes almost nothing worth having.

What an overpayment actually does
An overpayment goes straight off your balance. It does not reduce your compulsory monthly deduction, which stays locked at 9% of income above your threshold regardless of how much you owe. So overpaying does not free up any cash in your monthly budget. It only shortens the life of the loan, and only if the loan was going to end by being repaid rather than written off.
The write-off trap
This is where money gets lost. Suppose you are on Plan 2 with a balance heading for write-off in 30 years. You overpay £100 a month for a decade, then the loan is written off anyway. You have handed over £12,000 that bought you nothing, because the remaining balance, whatever its size, was going to be cancelled regardless. Use the calculator above: if it says Written off, an overpayment is money you will never see again.
When overpaying is worth it
- The calculator shows you clearing the balance before the write-off date. Overpaying then genuinely saves interest.
- You are a high earner on Plan 1 or Plan 5, where clearing the loan is realistic.
- You have no more expensive debt, a full emergency fund, and no unused employer pension match.
- Your loan rate is higher than what you could reliably earn elsewhere after tax.
How to make an overpayment
You can pay the Student Loans Company directly by bank transfer or card, either as a lump sum or a standing order. Be careful near the end of the loan: set up a Direct Debit for the final two years so you do not overpay past the balance. If you do overshoot, you can reclaim the excess.
Before you commit anything, read should I pay off my student loan early, which walks through the decision properly.
Frequently asked questions
Does overpaying reduce my monthly deduction?
No. Your payslip deduction is set by your salary, not your balance. It only stops when the loan is fully cleared.
Can I get an overpayment back?
Voluntary overpayments cannot be refunded. Payments taken in error, such as when you earned below the threshold, can be reclaimed.
Is a lump sum better than monthly overpayments?
A lump sum saves marginally more interest because it reduces the balance sooner. But the same caution applies: only if you will clear the loan at all.
