Plan 2 in one paragraph: if you started an English or Welsh undergraduate course between September 2012 and July 2023, you're on Plan 2. For 2026/27 you repay 9% of gross earnings above £28,470 per year. Interest is RPI to RPI+3% depending on your income, capped at the prevailing market rate. Outstanding balance writes off 30 years after the April you became first liable.
Who is on Plan 2?
- England: undergraduate courses started 1 September 2012 to 31 July 2023.
- Wales: undergraduate courses started 1 September 2012 onwards (Wales did not switch to Plan 5).
- Northern Irish students stay on Plan 1; Scottish students are on Plan 4.
- English students starting from August 2023 onwards are on the new Plan 5 — see our Plan 5 page.

The 2026/27 repayment math
9% of gross earnings above £28,470 per year. Same mechanic as Plan 1 but with a higher threshold and longer write-off horizon.
| Gross annual earnings | Annual repayment | Monthly repayment |
|---|---|---|
| £28,470 | £0 | £0 |
| £35,000 | £588 | £49 |
| £45,000 | £1,488 | £124 |
| £60,000 | £2,838 | £237 |
| £85,000 | £5,088 | £424 |
How Plan 2 interest works (and why it's punitive at high incomes)
Plan 2 interest is set by a sliding scale based on income, calculated using the RPI inflation rate from March of the previous calendar year:
| While studying | RPI + 3% |
|---|---|
| After course end, earning under £28,470 | RPI only |
| Earning £28,470 - £51,245 | RPI + 0% to 3% (sliding scale) |
| Earning over £51,245 | RPI + 3% |
Important: a "prevailing market rate" cap applies. When commercial rates fell, the headline Plan 2 rate was capped. As of 2026/27, the cap is regularly the binding constraint — meaning your interest may be lower than the formula above suggests. Check current rates at gov.uk.
Will I repay Plan 2 in full?
The Government's own modelling suggests roughly half of Plan 2 borrowers will not fully repay before the 30-year write-off. Whether you will depends primarily on three factors:
- Total balance at graduation (most Plan 2 borrowers graduate with £45,000-£65,000)
- Your earnings trajectory over the next 30 years
- How long the prevailing-market-rate cap remains in force on interest
A graduate earning £35,000 for life would repay £588 per year and clear £18,000 in 30 years — not enough to repay a £50,000 starting balance with interest. A graduate going from £40k to £80k by year 10 could repay it in full and then some.
The "graduate tax" mental model
If you're realistically going to be earning at modest professional salaries for most of your career, Plan 2 functions as a flat 9% income tax above £28,470 for 30 years. The balance is theatre — you'll never see it. The mental model of "this is a graduate tax" is more useful than "this is a debt".
For higher earners, the calculation flips: if you'll repay in full within 30 years anyway, then aggressive overpayment can save real money on interest, particularly if you're earning enough to be subject to the RPI+3% top rate.
Should I overpay Plan 2?
Use this rough decision tree:
- Realistic average earnings over the next 30 years < £45,000: very probably no. You're a "won't repay in full" borrower. Overpaying is paying voluntary tax.
- Average earnings £45k-£70k: uncertain. Depends on balance, interest cap, career trajectory. Run the student loan calculator for your specific numbers.
- Average earnings > £70k or already wealthy from inheritance/business sale: yes, you'll repay in full and large interest on the highest tier compounds. Overpaying can save tens of thousands.
Even in the "yes" case, the priority order should be: workplace pension match, ISA, pension top-up — then student loan overpayment. Tax-relieved retirement savings usually beat overpaying a 6-8% loan.
Worked example: graduate with £50,000 balance, £55,000 salary
Starting balance £50,000, RPI 3.5% so interest at RPI+3% = ~6.5% but capped at ~7.5%. Salary £55,000 growing at 3% nominally per year.
- Year 1 repayment: (55,000 − 28,470) × 9% = £2,388
- Year 1 interest: £50,000 × 7.5% = £3,750
- Net balance change Year 1: +£1,362 (loan grows despite repayment)
- By year 10, salary ~£72,000, repayment ~£3,917, interest ~£3,500, balance starting to decline
- Projected payoff: roughly year 22-23 before the 30-year write-off
This borrower would repay in full. Overpaying by £100/month from year 1 could shorten the term to year 17, saving roughly £14,000 of interest. But the same £100/month into a pension at 40% tax relief would be worth more than £200/month into the pension — a better deal even before investment growth.
Common Plan 2 mistakes
- Voluntarily overpaying when you're not on track to fully repay. You're handing HMRC money you weren't going to owe.
- Choosing a part-time year or sabbatical that drops you below the threshold by accident. Loan doesn't write off until 30 years; the balance keeps accruing interest. Plan deliberate income reductions.
- Mortgage applications treating Plan 2 as a regular debt. Some lenders deduct the full balance from affordability; better lenders correctly treat only the monthly repayment as a deduction. Shop around.
- Ignoring the prevailing-rate cap. The Plan 2 cap has materially reduced interest below RPI+3% in many recent years — check current rates before modeling worst case.
