UK Student Loans Explained: Plan 2 vs Plan 5 in 2026
Picture the scene: you've just graduated, landed your first proper job, and your payslip arrives looking slightly thinner than expected. A line marked "Student Loan Deduction" quietly lifts a chunk before you even see it. For millions of people across England, this is the reality — yet very few truly understand how the system works, which plan they are on, or whether they will ever actually pay their loan off.
If that sounds familiar, you are not alone. The UK student finance system is genuinely complex, and confusion between Plan 2 and the newer Plan 5 is widespread. Here is everything you need to know.
Who Is on Plan 2?
Plan 2 covers most graduates who started an undergraduate degree in England between 1 September 2012 and 31 July 2023. It is currently the most common repayment plan among working graduates.
Under Plan 2, you repay 9% of everything you earn above £27,295 per year (the 2026 threshold, which is subject to annual review). Crucially, the threshold is frozen until at least 2025 under existing policy, meaning more graduates are pulled into repayments as wages rise with inflation.
A practical example: If you earn £32,000 a year, the repayable portion is £32,000 minus £27,295 = £4,705. Nine per cent of that is £423.45 per year, or roughly £35 per month. It disappears from your pay before you notice it — handled via PAYE, just like income tax.
Any remaining Plan 2 debt is written off after 30 years, regardless of the balance.
Who Is on Plan 5?
Plan 5 applies to students who started an undergraduate course in England from 1 August 2023 onwards. If you began university in the autumn of 2023 or later, this is your plan.
Plan 5 looks similar to Plan 2 on the surface — you still repay 9% above a threshold — but the differences are significant:
- Repayment threshold: £25,000 per year (lower than Plan 2's £27,295)
- Write-off period: 40 years after the April following your graduation (10 years longer than Plan 2)
- Interest rate: Linked to the Retail Price Index (RPI) only, rather than RPI plus up to 3% as under Plan 2
The lower threshold means Plan 5 graduates start repaying sooner in their careers. On a £30,000 salary, a Plan 5 borrower repays 9% of £5,000 = £450 per year (£37.50 per month), compared to a Plan 2 borrower on the same salary repaying just 9% of £2,705 = £243.45 per year (£20.29 per month).
The 40-year write-off window is the element that attracts the most criticism. Many graduates — particularly those in lower-to-middle income careers — will spend four decades making repayments without clearing the debt, eventually having the remainder cancelled. In practice, the system functions less like a traditional loan and more like a graduate tax with a time limit.
Does the Interest Rate Actually Matter?
For most borrowers, the honest answer is: not as much as you might think.
Plan 5 interest is pegged to RPI, currently around 3.1% (as of early 2026). Plan 2 borrowers on higher incomes paid RPI plus 3% during their studies and early career — a rate that once reached over 7%.
However, because the majority of graduates never fully repay their loans before the write-off date, accumulating interest simply inflates a number that will ultimately be cancelled. Obsessing over the interest rate is largely irrelevant unless you are a high earner on a clear path to full repayment.
If you are trying to work out whether your loan is likely to be repaid in full — and therefore whether the interest rate should influence your decisions — tools such as the government's own student loan calculator and services like QuidCompare can help you model repayment scenarios alongside other financial products, giving you a clearer picture of where student loan repayments sit within your broader financial commitments.
Should You Make Voluntary Overpayments?
This is one of the most common questions graduates ask, and the answer is almost always no — unless you are specifically a higher earner who is likely to repay the full amount before write-off.
Here is why: if you overpay but do not clear the debt entirely before the write-off date, you have simply paid money you never needed to. The remaining balance would have been cancelled regardless. Unlike a mortgage or credit card, there is no general financial benefit to overpaying a student loan for average earners.
The exception: If you earn consistently above roughly £50,000 and are projected to repay your full balance within the plan's term, overpaying can reduce the total interest accrued. In that case, it is worth running the numbers carefully.
Practical Steps to Take Right Now
- Find out which plan you are on. Log in to the Student Loans Company portal at studentloansrepayment.co.uk to see your plan type, outstanding balance, and repayment history.
- Check your payslip. Your employer should be deducting the correct amount via PAYE. Errors are rare but do occur, particularly when starting a new job.
- Ignore the total balance (mostly). It is psychologically distressing to see a £50,000-plus figure, but for the majority of borrowers it is not a debt in the traditional sense. It will not affect your credit score, and it will not prevent you getting a mortgage.
- Do not let it stop you investing. Many graduates pause pension contributions or ISA savings in a misguided effort to tackle their student loan. In almost all cases, building long-term savings takes priority over voluntary loan repayments.
- Reassess if your income rises significantly. High earners on Plan 2 or Plan 5 should revisit the repayment maths periodically. What made no financial sense at £30,000 per year may look different at £60,000.
The Bottom Line
The student loan system in the UK is designed to be income-contingent — you only pay when you can afford to. Plan 2 and Plan 5 both follow this principle, but Plan 5 bites earlier and lasts longer.
For most graduates, the healthiest approach is to treat monthly deductions as a tax, focus on building financial resilience elsewhere, and only revisit the numbers if your income puts you on course to genuinely clear the debt. Understanding the system is the first step to making peace with it.
