UK Student Loan Repayment 2026/26

Student loan repayments in the UK are income-contingent — you only repay a percentage of income above a threshold. The loan does not affect your credit score. Below the threshold, no repayment is required regardless of balance size.

Repayment Formula

Annual Repayment = (Gross Income − Threshold) × Rate (9% or 6%)
Only applies when gross income exceeds the plan threshold
Multiple plans are calculated independently and summed

Example: £35,000 salary with Plan 2

Plan 2 threshold: £27,295
Income above threshold: £35,000 − £27,295 = £7,705
Annual repayment: £7,705 × 9% = £694/year (£58/month)

Early Repayment Analysis — Lump Sum vs Write-Off

Should you overpay your student loan or let it write off? Full payoff projection with interest.

Should you make voluntary lump-sum repayments? This analysis shows your projected payoff timeline and total repaid — compared to letting the loan write off naturally.

Plan 2/5: ~7.3% (RPI + 3%); Plan 1: ~5.5% (lower)

Frequently Asked Questions

What are the different UK student loan repayment plans?
There are 5 UK student loan plans: Plan 1 (pre-2012 English/Welsh loans and all Scottish loans before 2012) — 9% above £24,990. Plan 2 (post-2012 English/Welsh) — 9% above £27,295. Plan 4 (Scottish, post-2012) — 9% above £27,660. Plan 5 (new English undergraduate from 2023 onwards) — 9% above £25,000. Postgraduate Loan — 6% above £21,000. You can hold multiple plans simultaneously.
When does each student loan plan get written off?
Write-off timelines vary significantly. Plan 1: written off at age 65, or 25 years after repayment became due (whichever comes first). Plan 2: written off 30 years after first repayment. Plan 4: written off at age 65 or 30 years. Plan 5: written off 40 years after the April following graduation. Postgraduate Loan: written off 30 years after first repayment. Many Plan 2 and Plan 5 borrowers will never fully repay.
Is it worth making voluntary overpayments on a student loan?
It depends on your plan and likely income trajectory. If you are likely to clear the loan before write-off (typically lower balance, high income), overpaying makes financial sense as the interest rate is 7.3%+ on Plan 2/5. However, if you are unlikely to repay in full before write-off, every extra pound paid voluntarily is wasted — you would have been better off investing it. Plan 1 borrowers with lower rates (RPI or Bank of England base rate + 1%) have weaker case for overpaying.
Can I have more than one student loan plan at once?
Yes. Many postgraduate students have both an undergraduate loan (Plan 1, 2, 4, or 5) and a Postgraduate Loan. These are calculated and collected separately. If you have Plan 2 and a Postgraduate Loan, your employer deducts 9% above £27,295 (Plan 2) plus 6% above £21,000 (PGL) simultaneously — with each deduction calculated independently on your salary, not combined.
How is student loan repayment calculated on self-employment income?
Student loan repayments on self-employment income are calculated and collected through Self Assessment (your annual tax return). You calculate your income above the threshold and pay 9% (or 6% for PGL) on the excess as part of your tax bill. Unlike PAYE where deductions happen monthly, self-employed borrowers pay their student loan repayment as a lump sum via Self Assessment alongside their income tax and Class 4 NI.
