Student loan repayment calculator

See what you repay each month and whether you’re likely to clear your loan or have it written off.

A simplified projection: interest is added yearly and thresholds are held flat. Use it as a guide, not a forecast.

Should you pay off your student loan early?

For many graduates, especially on Plans 2 and 5, the loan works more like a graduate tax: if your earnings won’t clear the balance before it’s written off, extra payments may just reduce the amount written off. Early repayment makes more sense if the calculator shows you’ll clear the loan anyway, because then you save interest.
