For millions of UK graduates, the student loan system has shifted from a “fair contribution” to what many experts now call a UK student loan stealth tax. While headline tuition fees often dominate the news, it is the quiet manipulation of repayment thresholds and interest rates that is having the biggest impact on take-home pay in 2026.
If you are one of the 6 million people on a Plan 2 loan, here is the data-driven reality of what you will actually pay this year.
1. The April 2026 “Pay Rise” (The Good News)
Starting April 6, 2026, the Plan 2 repayment threshold is officially increasing from £28,470 to £29,385. Because you only repay 9% on income above the threshold, raising this “starting line” means you keep more of your salary each month.
Monthly Repayment: Today vs. April 2026 (Plan 2)
| Annual Salary | Monthly Repayment (Now) | Monthly Repayment (April 2026) | Monthly Saving |
| £30,000 | £11.47 | £4.61 | – £6.86 |
| £35,000 | £48.97 | £42.11 | – £6.86 |
| £45,000 | £123.97 | £117.11 | – £6.86 |
| £55,000 | £198.97 | £192.11 | – £6.86 |
In the short term, most Plan 2 graduates will see an extra £6.86 per month in their pocket starting this April.
2. The Stealth Tax Trap (The Bad News)
While the drop in April 2026 looks good on your payslip, the Chancellor has confirmed that this new £29,385 threshold will be frozen for three years (until April 2030).
As inflation pushes wages up while the threshold remains stuck, you are caught in “fiscal drag.” The Institute for Fiscal Studies (IFS) estimates that this freeze will cost the average borrower an extra £93 in 2027–28, rising to £259 more per year (£22/month) by 2030.
3. Repayment Burden Across All Plans
Each plan triggers a different threshold. If you aren’t sure which one you’re on, check your Student Loans Company (SLC) account.
UK Student Loan Thresholds (2026/27 Tax Year)
| Plan Type | Annual Threshold | Monthly Equivalent | Repayment Rate |
| Plan 1 | £26,900 | £2,241 | 9% |
| Plan 2 | £29,385 | £2,448 | 9% |
| Plan 5 | £25,000 | £2,083 | 9% |
| Postgraduate | £21,000 | £1,750 | 6% |
4. The Interest Rate Trap: Why Debt is “Ballooning”
For many, the debt isn’t just a loan; it’s an anchor. Interest rates are currently tied to the Retail Price Index (RPI), which is roughly 3.2%.
- The Floor: Interest is 3.2% (RPI) if you earn below the threshold.
- The Ceiling: For Plan 2 borrowers earning over £52,885, the rate spikes to 6.2% (RPI + 3%).
- The Reality: High interest means some graduates see their total debt grow by over £400 a month in interest alone, often far outpacing their monthly repayments.
