Should You Overpay Your Plan 2 Student Loan in 2026?

Figures are for the 2026 to 2027 tax year (6 April 2026 to 5 April 2027) and the interest rates that run from 1 September 2026 to 31 August 2027. Plan 2 covers undergraduate courses started in England between 1 September 2012 and 31 July 2023, and in Wales from 1 September 2012 onwards, as the House of Commons Library sets out. This is general information, not personal financial advice.

How does a Plan 2 loan actually work?

Your repayment is 9% of whatever you earn over £29,385 a year, and the size of your balance makes no difference to that figure. GOV.UK gives the threshold as £29,385 a year, £2,448 a month or £565 a week. Earn below it and you pay nothing.

Two people on the same salary, one owing £15,000 and one owing £60,000, hand over an identical sum each month. Your balance settles one question only: whether you clear it before the 30 years are up.

Here is what the 9% comes to in practice:

The write-off is the part that changes the answer. GOV.UK confirms that a Plan 2 loan is wiped 30 years on from the April in which repayments first became due, which is the April after you leave your course, not the date you graduated or started. Whatever is left then, including all the interest, simply goes. And most people do have something left: of those who began full-time study in 2022/23 on Plan 2, the Commons Library says only about one in three is forecast to clear the balance.

What interest rate are you paying, and does it matter?

Between 1 September 2026 and 31 August 2027 your rate is somewhere between 4.1% and 6%, set by what you earn. Plan 2 interest slides with income: it is RPI alone (4.1%, taken from March 2026) if you earn £29,385 or less, and climbs on a straight line to RPI plus 3% (7.1%) once you reach £52,885.

The government then capped the maximum at 6% for this one year. GOV.UK announced the cap on 7 April 2026, and the Commons Library records that it runs only to 31 August 2027.

Work the sliding scale against that cap and you get a figure nobody publishes: the cap starts to bite at about £44,270 of income. Below that, your rate is whatever the slide gives you. From roughly £44,270 upwards, everyone pays the same 6% this year, whether they earn £45,000 or £145,000.

For most borrowers the rate is a distraction, because interest changes only the balance, never the monthly deduction. It matters to exactly one group: the people who will clear the loan. For them, every pound of interest is a pound they really pay.

Will you clear the loan before it is written off?

This is the whole decision, so it is worth answering properly rather than guessing from your statement.

Start with the simplest version: at what income does your balance stop growing? That is the point where your yearly repayment matches the interest added. Below it, the balance climbs however diligently you pay; above it, it starts to fall.

Our £50,000 row lands within a few hundred pounds of the Institute for Fiscal Studies figure of around £63,000, which it published in February 2026 on the previous year's threshold and rates. That is a useful check that the method is sound.

Clearing a balance is harder than holding it flat, because you need to outpace the interest by enough to finish inside 30 years. If your income is comfortably above the figure in that table and likely to stay there, you are probably a full repayer. If you are below it, your balance is still growing and the write-off is doing the work.

What does overpaying £10,000 actually do?

It depends entirely on which side of the write-off line you land, and the answer is not a gentle slope. Take a hypothetical graduate with a £55,000 balance and 30 years of repayments still to run, who pays £10,000 off today.

Assumptions: a £55,000 balance with the full 30 years left, salary and thresholds both rising with RPI so the figures are in today's money, the structural interest rate of RPI to RPI plus 3%, and the 2026/27 6% cap treated as the one-year measure it is. Totals include the £10,000 where it was paid. These are illustrations, not forecasts.

Three things stand out.

On £35,000 and £45,000 the £10,000 is simply gone. The loan was always going to be written off, so the overpayment buys nothing at all and the total repaid rises by exactly the amount paid in.

At £55,000 it is worse than useless. The overpayment is just big enough to tip the loan from "written off with a balance left" to "cleared with seven months to spare", which means paying £8,618 more than doing nothing. On these assumptions the crossover sits at roughly £57,000 of steady income. That is the number to hold on to.

And notice £60,000, where the total repaid without overpaying (£82,660) is higher than at £65,000, £75,000 or £90,000. Sitting just below the level where you would clear the loan is the most expensive place to be, because you pay all 30 years and still have a balance wiped.

The bigger your overpayment relative to the balance, the more likely it is to tip you across the line. That is the trap: a payment large enough to matter is also large enough to turn a write-off into a full repayment.

When is overpaying a Plan 2 loan worth it?

It is worth considering when nearly all of these are true:

1. Your income is well above the break-even figure for your balance and you expect it to stay there for most of the remaining term.
2. Your balance is small enough, or your income high enough, that you are clearly going to clear it anyway.
3. You have no more expensive debt. A credit card or car finance at 20% beats a student loan at 6% every time.
4. You have an emergency fund you are not touching.
5. You will not need the cash for a deposit, a pension or anything else inside the next few years.
6. Your savings are earning less after tax than your loan rate.

Point six is doing less work this year than it looks. With easy-access savings around 4% and the loan capped at 6%, the gap is real but modest, and a basic rate taxpayer's savings interest is taxable beyond the Personal Savings Allowance while loan interest is not. Run the comparison on your own numbers rather than assuming 6% always wins.

The case against is stronger than most people expect, and the IFS names the reason better than we could: overpaying means giving up the insurance built into the loan. If your earnings turn out lower than you planned, because of redundancy, illness, a career change or time out to raise children, the write-off would have covered you. Money already handed over cannot come back to cover you instead.

And it genuinely cannot come back. GOV.UK is explicit: "You cannot get a refund of any extra repayments you make." The same page warns that you might not benefit, and suggests checking your write-off date first.

If the money is going somewhere other than the loan, the MySums Loan Overpayment Calculator will show what the same lump sum does against a mortgage or a personal loan, where overpaying reduces what you owe pound for pound.

Does the 2027 threshold freeze change the answer?

It makes repayments creep up, but it does not change who should overpay. At the Autumn Budget on 26 November 2025 the government froze the Plan 2 threshold at its April 2026 level of £29,385 for three years from April 2027, instead of raising it with inflation, with RPI uprating due to resume in April 2030. The interest rate thresholds of £29,385 and £52,885 are frozen for the same period.

The IFS has costed it. If you still hold a Plan 2 balance and earn more than £30,416, that is £93 extra in 2027/28, rising to £259 extra (about £22 a month) by 2029/30. Over a lifetime it adds roughly £3,000 on average for the 2022 university entry cohort, and about £5,000 for those in the third decile of lifetime earnings, who come off worst.

More repayment earlier does pull a few borderline borrowers towards clearing their loans, so if you were already close to the crossover the freeze nudges you towards overpaying. For anyone comfortably below it, paying more each year does not make the write-off any less likely. Reacting to the freeze by overpaying is the wrong instinct for most people.

One distinction worth knowing, and most coverage still files it as unconfirmed: according to the Commons Library, ministers in Cardiff have said Welsh borrowers will not have their threshold held down this way. Welsh Plan 2 borrowers should check Student Finance Wales for their own position before planning around it.

What if you are on a different plan?

The same logic applies, with different numbers. GOV.UK lists the 2026/27 thresholds as £26,900 for Plan 1, £29,385 for Plan 2, £33,795 for Plan 4 in Scotland, £25,000 for Plan 5 and £21,000 for a Postgraduate Loan. Plan 1, 2, 4 and 5 all repay 9% above the threshold; a Postgraduate Loan takes 6%.

What differs is the write-off period and the interest. Plan 1 is written off after 25 years and charges the lower of RPI or base rate plus 1%, currently 4.1%. Plan 5, for English courses started from 1 August 2023, runs for 40 years at RPI only, so in real terms you never pay more than you borrowed, but the longer term and lower threshold mean more borrowers clear it. A Postgraduate Loan runs 30 years at RPI plus 3%, capped at 6% this year.

A longer term and a lower threshold both make full repayment more likely, which makes overpaying more likely to be worthwhile on Plan 5 than on Plan 2. If you are not sure which plan you hold, the MySums UK student loan repayments guide runs through how to tell.

What should you do next?

Find three numbers: your current balance from your Student Loans Company online account, the April when your repayments first became due, and a realistic view of your income over the next decade. Put them into the Student Loan Repayment Calculator to see whether the projection has you clearing the loan or having it written off.

If it shows a write-off, stop thinking of the balance as debt and ignore the statement. If it shows full repayment with years to spare, overpaying is worth a proper look, and the size of the saving depends on how much interest you cut out. If it sits near the crossover, the honest answer is that nobody can tell you, because it turns on earnings you cannot predict, and the asymmetry is unkind: a wasted overpayment costs you the whole amount, while a missed one costs you only some interest.

Rates and thresholds move at Budgets and each new tax year, and interest is reset every September, so check the current figures before you commit anything.
