9% of everything you earn over £25,000

Plan 5 — the loan for students in England who started courses from August 2023 — takes 9% of your income above £25,000 a year. On a £40,000 salary that is £1,350 a year, or £112.50 a month, leaving take-home pay of about £30,970 (£2,581 a month) after tax, National Insurance, and the loan.

The first Plan 5 borrowers made their first-ever repayments in April 2026, so 2026/27 is the first full tax year these deductions appear on payslips.

Repayments at common salaries

SalaryPlan 5 (per year)Plan 5 (per month)Plan 2 (per year)
£30,000£450£37.50£55
£35,000£900£75.00£505
£40,000£1,350£112.50£955
£50,000£2,250£187.50£1,855

Both plans charge the same 9% rate — the difference is where repayment starts. Plan 5’s threshold is £25,000, held at that level for 2026/27; Plan 2’s is £29,385. That £4,385 gap is worth £395 a year at every salary above both thresholds, and it bites hardest at the bottom: at £30,000, a Plan 5 graduate repays £450 a year while a Plan 2 graduate repays £55 — roughly eight times as much for the newer cohort.

How Plan 5 works

Repayments behave like a tax, not like a normal loan:

  • Automatic: deducted through PAYE alongside income tax and NI. You never choose the amount.
  • Income-contingent: earn below £25,000 in a pay period and the deduction stops. Nothing accrues as “missed”.
  • 9% above the threshold only: a £1,000 pay rise above £25,000 costs £90 a year in extra repayments, regardless of your balance.
  • Written off after 40 years: per GOV.UK, any balance left 40 years after the April you were first due to repay is cancelled — for the first cohort, that means the mid-2060s.

Plan 5 vs Plan 2: the real trade

Plan 5 is a deliberately different bargain from Plan 2 (England and Wales courses starting September 2012 to July 2023):

  • You pay from a lower salary — £25,000 vs £29,385 — so monthly deductions start earlier in your career and are larger at every income level.
  • You pay for longer — the write-off moved from 30 years to 40, stretching repayments across most of a working life.
  • But interest is gentler — Plan 5 charges RPI only, with no added percentage on top, unlike Plan 2’s income-linked RPI-plus-up-to-3% (GOV.UK). Balances still grow with inflation, but they no longer compound ahead of it.

The net effect: more Plan 5 borrowers will repay their loans in full, and fewer will reach the write-off — that is what a lower threshold and a 40-year term are designed to do.

What it does to your marginal rate

Stack the deductions and a Plan 5 graduate in the basic-rate band loses 37p of each extra pound: 20% income tax, 8% National Insurance, 9% loan. In the higher-rate band it is 51p (40% + 2% + 9%). That is worth knowing when you weigh up a pay rise — a £1,000 rise at £30,000 with a Plan 5 loan is £630 in your pocket, not £720. What a pay rise is actually worth runs those numbers without a loan for comparison.

Whether voluntary overpayments make sense depends on the same question as Plan 2, stretched over a longer horizon: will your lifetime earnings clear the balance before the 40-year write-off? High and rising earners save real interest by overpaying; for others, the write-off does the work and overpayments are money gone. That depends on your career path, not a rule of thumb.

Common questions

What is the Plan 5 student loan threshold?

£25,000 a year for 2026/27. You repay 9% of everything you earn above it, deducted automatically through PAYE. Below £25,000, you repay nothing.

When did Plan 5 repayments start?

April 2026. Plan 5 covers students in England who started courses from August 2023, and the rules set the earliest possible repayment date at 6 April 2026 — so the first cohort made their first-ever deductions in the 2026/27 tax year.

How much do you repay on Plan 5 at £30,000?

£450 a year, about £37.50 a month — 9% of the £5,000 above the £25,000 threshold. On the same salary, a Plan 2 borrower repays £55 a year, because Plan 2's threshold is £29,385.

When is a Plan 5 loan written off?

40 years after the April you were first due to repay, per GOV.UK — a decade longer than Plan 2's 30 years. Any balance still outstanding at that point is cancelled.

Is Plan 5 worse than Plan 2?

It takes more from lower salaries, sooner: the £25,000 threshold means £395 a year more in repayments than Plan 2 at £30,000, and the write-off is 40 years instead of 30. In its favour, Plan 5 charges interest at RPI only, with no added percentage, so balances grow more slowly.
