The BBC reports that Plan 2 student loan interest in England has been capped at 6%. That is welcome news if you are a high earner heading for full repayment, but for most Plan 2 borrowers the effect on what you actually pay is smaller than the headline suggests. Here is why the two things are not the same.
This analysis responds to reporting by BBC. We recommend reading the original alongside it: Plan 2 student loan interest rates capped at 6% in England ↗
What has actually been reported?
The headline is straightforward: Plan 2 student loan interest in England is now capped at 6%. Under normal Plan 2 rules the interest rate slides with income, running from RPI at the lower threshold of £29,385 up to RPI plus 3% once you earn above the upper threshold of £52,884. A hard cap of 6% sets a ceiling on top of that formula.
This is not the first time a cap has appeared. The government already operates a separate mechanism called the Prevailing Market Rate cap, which limits student loan interest so it does not exceed what borrowers would typically pay in the commercial market. A fixed 6% figure is simpler and more transparent, and it removes some of the volatility that RPI-linked interest has produced in recent years.
One important point the headline does not tell you: interest on a student loan is not a normal debt cost. It changes your outstanding balance, but it does not change your monthly repayment. What you pay each month is fixed at 9% of income above the threshold, regardless of the interest rate. So the cap matters for your balance, not your cash flow.
