The £47,730 question facing England’s graduates

A number on a student-loan statement can be psychologically enormous and financially misleading at the same time.

For higher-education borrowers entering repayment in England in 2025-26, the provisional average balance was £47,730. That is more than four times the average recorded in 2006-07. Yet the size of the balance does not, by itself, determine what a graduate pays each month.

That distinction is becoming more important as the first Plan 5 borrowers move into repayment. Plan 5 covers undergraduates who started from August 2023. From April 2026, repayments are due at 9% of earnings above £25,000 a year. If income falls below the threshold, the normal payroll deduction stops. If income rises, the deduction rises with it.

For someone planning a career, that makes student debt behave differently from a credit card, car loan or mortgage. The relevant personal-finance question is not “How quickly can I clear £47,730?” but “What will the repayment formula do to my disposable income over the earnings path I am likely to have?”

The current rules make that visible. A Plan 5 borrower earning £33,000 is shown in official guidance as repaying about £60 a month. At higher salaries the figure climbs because 9% is charged on the slice of earnings above the threshold. The deduction is taken alongside income tax and National Insurance for employees paid through payroll.

This can turn salary comparisons into something more complicated than the headline figure. A £5,000 pay rise is not worth £5,000 in extra spendable income even before ordinary tax is considered, because a Plan 5 borrower also gives up 9% of the part of the rise that sits above the repayment threshold. For graduates weighing jobs, promotions or locations, the student-loan deduction is one more marginal charge to include in the calculation.

The system is designed that way deliberately. Repayments track income, not the outstanding balance. Two graduates on the same Plan 5 salary can have very different loan balances and still make the same compulsory payment that year. The balance becomes decisive only when it affects whether the loan is eventually repaid in full.

That is where lifetime earnings matter. Plan 5 loans can be written off 40 years after the April in which the borrower first becomes due to repay. The Department for Education forecasts that 55% of full-time undergraduate borrowers starting in 2025/26 will eventually repay in full. The remaining 45% are expected not to clear the entire balance, although most will repay at least part of what they borrowed.

This creates a personal-finance trap for anyone who treats all student debt like ordinary debt. Making extra voluntary payments may reduce interest and shorten the life of the loan for a borrower who is on track to repay everything. But for someone who would otherwise reach the write-off point with a balance remaining, aggressive overpayment could mean using cash today to repay money that would never have been collected under the normal schedule. Whether overpayment makes sense depends on expected income, career stability, existing savings, other debts and the remaining term.

The size of future borrowing is also moving higher. The government forecasts that a full-time undergraduate starting in 2025/26 will borrow £45,190 on average over the course of study. For a 2030/31 starter, that rises to £50,700. Four years of funding can be higher still: the current forecast for a 2025/26 starter taking four years of full-time funding is £66,430 in borrowing before the effect of interest on the balance at repayment.

Tuition charges are part of that climb. For the 2026/27 academic year, the maximum standard full-time fee at approved fee-cap providers with a Teaching Excellence Framework award and an access and participation plan has risen to £9,790. The figure is scheduled to reach £10,050 in 2027/28.

At the national level, the higher-education loan balance has reached £294.6 billion, up 10.5% in a year. That is a public-finance story. For an individual graduate, however, the more useful way to read the same system is through monthly cash flow and career trajectory.

A graduate on a modest salary may have a large balance but a relatively small repayment. A high earner may clear the loan in full and therefore care much more about interest and voluntary payments. A mid-career borrower may find that promotions raise both take-home pay and the student-loan deduction for years.

The result is a debt that sits awkwardly between personal liability and payroll policy. It can affect how a worker evaluates a bonus, a second job, a move abroad or a decision to overpay, while still behaving very differently from consumer credit.

For England’s new graduates, the £47,730 headline is therefore only the starting point. The more consequential number is the share of future earnings that the repayment system will claim, and for how long.
