Student Loan Repayments Explained: How They Actually Work

If you went to university in the UK, chances are you've got a student loan — and unlike most debt, it doesn't work like a normal loan at all. There's no debt collector, no fixed monthly bill, and for a lot of people, no repayment ever leaves their account until their income crosses a certain line.

It only comes out once you earn enough

Student loan repayments aren't due until your income passes a set threshold, and even then, they're taken automatically through the payroll system alongside tax and National Insurance — you don't have to do anything yourself if you're employed. Which plan you're on depends on when and where you studied:

• Plan 1 — mostly pre-2012 English and Welsh starters, and most Northern Irish students.
• Plan 2 — most English and Welsh students who started between 2012 and 2023.
• Plan 5 — English students who started from 2023 onwards.
• Postgraduate Loan — for those who took out a Master's loan.

Each plan has its own repayment threshold, and these are reviewed and updated most years, so it's worth checking the current figures on gov.uk rather than relying on a number you saw a while ago. As a rough guide, thresholds tend to sit somewhere in the mid-to-high £20,000s a year, with Plan 5 currently the lowest of the group.

How much comes off

Once you're earning above your threshold, you repay 9% of everything above it (postgraduate loans are repaid separately, at 6%, and can run alongside an undergraduate plan). So if your threshold is £25,000 and you earn £30,000, you'd repay 9% of the £5,000 difference — not 9% of your whole salary.

It behaves differently from other debt

A few things make student loans unusual:

• They don't appear on your credit report and don't affect your credit score.
• Nothing is repossessed and nobody chases you if your income drops — repayments simply stop until you earn enough again.
• Any remaining balance is written off completely after a set number of years (typically 30 or 40, depending on your plan), whether or not you've paid it all off.

Because of that last point, many financial guides — including this one — treat a student loan less like traditional debt and more like an extra tax you pay while your income is above a certain level, since a large share of borrowers never clear the balance before it's written off.

Should you pay it off early?

For most people on Plan 2 or Plan 5, overpaying isn't the obvious win it would be with a credit card or personal loan, precisely because so many balances get wiped before they're repaid in full. It can make more sense for higher earners who are likely to clear the loan anyway, or those close to the write-off point already. There's no one-size-fits-all answer, so it's worth running your own numbers before making extra payments.

Action step

Log into your payslip or the Student Loans Company portal and check three things: which plan you're on, your current threshold, and your outstanding balance. Knowing where you stand makes it much easier to judge whether extra repayments are worth it for you.
