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

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.
