Student Tuition Fee Loan Repayment Explained (2026/27)

How tuition fees actually turn into a loan

When you accept a place at a UK university, the Student Loans Company (SLC) pays your tuition fees — up to £9,535 a year for most English universities in 2026/27 — directly to the institution on your behalf. You never see this money. It is added to your student loan account alongside whatever maintenance loan you draw down for living costs, and from day one both amounts sit inside a single combined balance that starts accruing interest.

This matters because many graduates assume they are repaying "the fees loan" and "the maintenance loan" separately, perhaps in some order of priority. They are not. HMRC and the SLC track one number: your total outstanding balance. Every repayment reduces that single figure, regardless of how much of it originally related to fees.

The repayment mechanism: income, not balance

Student loan repayment in the UK is unusual among consumer debt because it is entirely income-contingent. You never repay a fixed monthly instalment based on how much you borrowed. Instead:

• If your income is below the repayment threshold for your plan, you repay nothing that year.
• If your income is above the threshold, you repay a fixed percentage of the amount above it — not a percentage of your total balance.

For 2026/27, the relevant thresholds and rates are:

Most students starting an undergraduate degree in England from September 2023 onwards are on Plan 5, which has the lowest threshold of the undergraduate plans but also the longest write-off period.

Worked example: a graduate earning £32,000

Suppose you are on Plan 5 and earn £32,000 a year through PAYE employment.

• Income above threshold: £32,000 − £25,000 = £7,000
• Repayment: 9% × £7,000 = £630 a year, or £52.50 a month

This deduction is calculated on qualifying income (broadly gross pay before pension contributions taken via salary sacrifice reduce it further) and comes off your payslip automatically once your tax code shows a student loan plan. It sits alongside — not instead of — income tax and National Insurance.

Using the current tax bands: on £32,000, income tax is 20% on £19,430 (£32,000 − £12,570 personal allowance) = £3,886, and employee NI is 8% on £19,430 = £1,554.40. Add the £630 student loan repayment and total deductions are £6,070.40, leaving take-home pay of £25,929.60 a year.

Interest: how the fees element grows

Plan 5 loans accrue interest at the RPI rate only, both during study and after graduation, with no extra percentage layered on top regardless of income. This is a deliberate design change from Plan 2, which could charge up to RPI+3% for higher earners. In practice this means the tuition fee portion of your loan — often the largest single component, at up to £9,535 a year — can grow substantially over a three or four-year course even before you start repaying, because interest accrues throughout your studies.

Why write-off timing matters more than the interest rate

For the majority of Plan 5 graduates, the debt is never fully repaid before the 40-year write-off point. Because repayments are capped at 9% of income above a modest threshold, and because interest continues to accrue on unpaid balances, many graduates on average earnings will still owe a substantial sum — potentially including a large chunk of the original tuition fee borrowing — when the debt is wiped clean.

This is why financial advisers increasingly describe the tuition fee loan as behaving like a graduate tax rather than a conventional loan: what you pay each month depends only on your income, and what happens to the underlying balance is largely irrelevant to most borrowers' financial planning, except in one case — very high, sustained earners who are on track to clear the balance before the 40-year cut-off, for whom voluntary overpayments could in principle reduce total interest paid.

Should you overpay to reduce the tuition fee element faster?

For most graduates, no. Because the loan is written off regardless of the remaining balance, extra payments only benefit borrowers who would otherwise fully repay before the write-off date — typically high, early-career earners. If you are unsure whether you fall into this group, model your likely lifetime earnings and compare the projected balance at year 40 using the SLC's own repayment calculator before making voluntary extra payments; these cannot usually be reversed once made.
