Overpay or Invest

Plan 2 vs Plan 5: what's actually different?

. Figures are for 2026–27 and are compared with GOV.UK every month. How we check.

If you started an English undergraduate course around 2023 it’s easy to assume Plan 2 and Plan 5 are close cousins. They share a repayment rate, but the other terms differ in ways that change what you’ll pay over a career.

What that means in practice

Plan 5 starts taking money sooner. Its threshold is lower, so you begin repaying at a lower salary and, at any given income, repay more each year than someone on Plan 2. See how much will I repay? for the numbers.

Plan 5 is charged less interest at higher incomes. Plan 2’s rate climbs with income; Plan 5’s doesn’t. For a high earner that can make Plan 5 cheaper per pound owed.

Plan 5 runs for longer. A 40 years write-off period against 30 years means more time for a balance to be repaid, and less chance of anything being cancelled unpaid.

Who tends to come out better

There’s no single answer, because it depends on your salary path:

These are patterns, not promises. Your own salary growth, career breaks and start date all change the result, which is why it’s worth running your own figures through the calculator rather than relying on a rule of thumb.

Why it matters for overpaying

Overpaying only makes sense when you’d otherwise repay the loan in full. That’s less common on Plan 2 for many people and more common on Plan 5, so the same salary can give different answers on the two plans. For the reasoning, see should I overpay my student loan?, and the plan-specific guides for Plan 2 and Plan 5.
