A warning has been issued for UK households over a £136,000 repayment trap that is hitting people hard. Those earning between £45,000 and £50,000 are being caught in a costly 'repayment trap' that could see them hand back nearly three times what they borrowed, according to new analysis.
Research Findings
Research by wealth manager Rathbones shows that individuals on mid-range salaries can end up repaying more than both lower and higher earners, simply because they stay in debt the longest. A graduate starting out on around £47,000 with a £50,000 Plan 2 student loan could repay a staggering £136,000 over 30 years, making it the worst financial outcome under the current system.
How the Trap Works
The problem lies in how interest builds up. Those in the £45,000 to £50,000 bracket make steady repayments but not enough to significantly reduce the balance, allowing interest — capped at up to 6% — to accumulate for decades.
Ed Wood, financial planning director at Rathbones, said: 'Many people assume the highest earners are worst hit by student loans, but the reality is more complex. Middle earners can end up paying the most simply because they’re trapped repaying for longer, allowing interest to build up year after year.'
Comparison by Salary
The analysis, based on a £50,000 Plan 2 loan, shows that:
- £30,000 starters repay about £50,000 over 30 years, with much of the balance written off.
- £40,000 starters repay just over £100,000, yet still don’t clear the debt.
- £47,000 starters repay the most at around £136,000.
- £50,000 starters repay roughly £122,000.
- £63,000 starters repay far less — about £90,000 — because they clear the loan quicker.
Expert Advice
Mr Wood added: 'The headline debt figure can look frightening, especially for lower earners, but what really matters for most people is the monthly repayment, not the balance. In that sense, student loans behave far more like a graduate tax than a conventional debt. But as earnings rise over time, the maths shifts — and paying the loan off can start to make sense.'
He further noted: 'From experience with clients, many parents and grandparents have high expectations for their children or grandchildren and assume they’ll go on to earn strong salaries. As a result, they often plan to pay university fees upfront to spare them the burden of student debt. Grandparents may also see a double benefit: helping with fees now while potentially reducing a future inheritance tax bill. However, there’s no one-size-fits-all answer. The key is understanding how student loans actually work before making any irreversible decisions.'
