UK Student Loan Repayment Explained — How Much Do You Actually Pay?

Student loans in the UK work nothing like a normal loan — and that's actually good news. You don't make fixed monthly payments. You don't get chased if you can't pay. And for many people, the loan gets written off before they ever clear it. This guide explains exactly how it works, how much comes out of your pay, and whether you should ever think about overpaying.

It's Not Like a Normal Loan — Here's Why That Matters

A standard bank loan charges you interest and expects fixed monthly payments regardless of what you earn. A UK student loan works the opposite way. You only repay a percentage of what you earn above a certain threshold. If you earn below that threshold, you pay nothing — not even interest gets chased. If you lose your job, repayments stop automatically. Think of it less like a debt and more like a graduate tax that only applies when you can afford it. This is why most financial advisors say you shouldn't stress about your student loan the way you'd stress about credit card debt or an overdraft.

Which Plan Are You On?

Your repayment plan depends on when and where you studied. Here's how to work out which one applies to you:

Not sure which plan you're on? Check your student loan online at studentloansrepayment.slc.co.uk or look at your payslip — it will show which plan is being deducted.

When Do Repayments Start?

Repayments start the April after you graduate or leave your course — but only if you're earning above the threshold. If you graduate in June and start work in September, your first repayments will come out the following April. Repayments are collected through PAYE automatically — your employer deducts them from your salary before you ever see the money, just like income tax and National Insurance. You don't need to set anything up or make any manual payments.

How Much Do You Actually Pay Each Month?

The repayment rate is 9% of everything you earn above the threshold. Nothing below the threshold is touched. Here's what that looks like in practice for a Plan 2 loan:

At £30,000 a year that's £20 a month. At £35,000 it's £57. It's genuinely not the crippling debt repayment most people fear. The psychological weight of student debt often far outweighs the actual financial impact.

Will You Ever Actually Pay It Off?

Honestly — many people won't, and that's by design. Plan 2 loans are written off after 30 years. Plan 5 loans after 40 years. The majority of graduates on Plan 2 are projected to never fully repay their loan before the write-off date. This is important to understand because it changes how you should think about the loan. If you're unlikely to clear it in full regardless, making extra voluntary repayments doesn't make financial sense in most cases — you'd be paying off a debt that was going to disappear anyway.

Should You Overpay Your Student Loan?

For most people — no. Here's the logic. If your loan will be written off before you clear it, any overpayments you make are essentially a gift to the government. The money is gone. You don't get it back. The only scenario where overpaying makes sense is if you're a high earner on track to fully repay the loan before write-off — typically someone earning £50,000+ consistently throughout their career on a Plan 2 loan. For everyone else, that money is almost always better deployed elsewhere — an ISA, a pension, paying off high-interest debt like a credit card or overdraft. If you're unsure, it's worth running the numbers for your specific salary.

Does Your Student Loan Affect Your Credit Score?

No. Your student loan does not appear on your credit file and does not affect your credit score. However, it does affect your mortgage affordability assessment. When you apply for a mortgage, lenders will ask about your student loan repayments because they reduce your monthly disposable income. A £57/month student loan repayment means £57 less of income available to service a mortgage — so it can slightly reduce the amount you're able to borrow. It won't stop you getting a mortgage, but it's worth being aware of when you're planning.
