Imagine paying off debt… only to watch the balance creep higher each month.
This is the harsh reality for many UK graduates right now when it comes to their student loan. Recent coverage in The Times and Sky News has spotlighted the issue, with social media filled with stories from young professionals doing everything "right" yet feeling trapped.
Take this junior doctor’s post: “I’ve been a doctor for three years. My salary deductions don’t even touch the interest. Balance: £106,355. Interest added last year: £2,760. Repaid: £2,378. It’s demoralising.”
Some commentators have even questioned whether today’s student loan terms would be accepted if they were introduced today.
Why student loan balances rise for some, even when they repay
The reason lies in how UK student loan interest works, especially under Plan 2 (which
covers most England/Wales students who started university between 2012–2023).
Repayments are fixed at 9% of the graduate’s income above a minimum threshold – regardless of how much interest is being added, meaning student loan balances can grow even while repayments are being made. Those students with larger loans are most likely to face the issue as interest is charged on the outstanding balance, while repayments depend only on income.
Current Plan 2 interest rate bands as of January 2026 are as follows:
| Income Level |
Interest Rate |
Approx. Rate (RPI 3.2%) |
| ≤ £29,385 (from Apr 2026) |
RPI only |
~3.2% |
| £29,386 – £52,885 |
Sliding scale up to RPI + 3% |
Up to ~6.2% |
| ≥ £52,885 |
RPI + 3% |
~6.2% |
Higher earners can face the fastest growth as their monthly repayment percentage is the same as lower earners, but the interest rate is higher. If their repayments don’t cover the interest on the student loan each month, then the balance rises.
Other plans have different rules but the risk remains:
- Plan 5 (England, starting after Aug 2023): interest rate equal to RPI (~3.2%).
- Postgraduate loans: Interest rate equal to RPI + 3% (~6.2%), 6% repayment rate.
- Plan 1 & 4 (older/Scotland/NI): Interest rate lower of RPI or Bank Rate +1% (~3.2% currently).
The good news is that if your children are not yet at university age, then you can potentially help by building a lump sum to cover all or part of their university fee costs so they don’t need to borrow as much.
Time is your superpower
Graduates face compounding debt immediately. But depending on the age of your child, you could have up to eighteen years before university decisions even arrive. Small, consistent contributions made early can grow into meaningful sums to help towards university fees later through the power of compounding.
Over eighteen years, £1 invested up front grows to roughly £2.40 if there is 5% annual growth, or close to £4 with 8%. Of course, returns are not guaranteed, but the asymmetry between university graduates and new parents is this: one faces debt immediately - the other has years to prepare.
A better start doesn’t necessarily mean paying it all. It can mean easing the burden:
- Less reliance on borrowing
- A buffer for rent, books, or living costs
- Help with early-life expenses like deposits
- Freedom to choose careers based on passion, not just salary
Most families cannot set aside very large lump sums for the future. But many can start small, and over long periods small contributions can add up to more than expected.
A modest monthly contribution, set up once and left to run in the background; occasional top-ups when circumstances allow; birthday gifts that become investments rather than plastic: all of these can build a pot to help towards your child's university costs.
Tools like tax-free Junior ISAs make this straightforward. With Beanstalk, you can set up automatic savings in minutes and we make it easy for family & friends to contribute too.
A final note on risk and reality
Investing carries risk, markets fluctuate. But over decades, time can smooth out the ups and downs. The bigger danger over long periods might simply be not starting at all.
The student loan system will almost certainly keep changing. Governments regularly adjust thresholds, interest rules, and repayment terms. For example, recent changes have frozen Plan 2 repayment thresholds at £29,385 until around 2030.
But here's the good news for new parents: you don't have to wait around for the next policy update. You can start building a stronger financial foundation for your child right now, before university even begins. You cannot change the system, but you can change your child’s starting point and over time, that changes everything.
