Is the Repayment Calculator free?
Yes. It is completely free, with no sign-up, no watermark, and no usage limits.
Does it use a specific currency?
No. Amounts are currency-neutral and use the same unit across all inputs, so it works in any country.
How long will it take to repay £15,000 at 9%?
At £350 a month it takes 52 months (4 years 4 months) and costs £3,163.62 in interest. Each month interest is added on the remaining balance, and whatever is left of the repayment reduces the debt.
Do extra repayments make a big difference?
Yes, because every extra pound goes straight to the balance and stops interest compounding on it. Enter an extra monthly amount to see the months and interest it saves; check your lender allows overpayments without a fee first.
