How to use the UK credit card repayment calculator
Enter your card balance and APR from your statement. Then either type what you can afford each month to see when you’ll be debt-free, or switch to I want to be debt-free in… to see the monthly repayment you need.
Minimum repayments and balance transfers
The comparison table shows your plan next to paying only the minimum. Set the minimum payment rule to match your statement. Tick Compare a balance transfer to see what a 0% card would save after the transfer fee. The repayment plan lists every month and downloads as a CSV file.
Assumptions
No new spending goes on the card, the APR stays the same and interest is worked out monthly. Late payment and other fees aren’t included. Results are estimates, not financial advice. Free, confidential debt help is available from MoneyHelper, StepChange and Citizens Advice.
Frequently asked questions
How long will it take to pay off my credit card?
It depends on the balance, the APR and how much you pay. A £3,000 balance at 27% APR takes 27 months to clear at £150 a month, with £1,030 of interest.
What happens if I only make the minimum repayment?
The minimum is usually 1% to 2.5% of the balance plus interest, so it shrinks as the balance falls. With 1% plus interest (at least £5), the same £3,000 takes over 29 years to clear and costs £6,515 in interest.
What is persistent debt?
Under FCA rules, if you’ve paid more in interest, fees and charges than off your balance over 18 months, your card provider must contact you about paying it off faster. After 36 months they must offer a way to repay over a reasonable time, and may suspend your card.
Is a 0% balance transfer worth it?
Usually, if you can clear most of the balance in the 0% period. You pay a one-off fee, often around 3%, and any balance left afterwards is charged the card’s standard rate. With £150 a month, transferring £3,000 to an 18-month 0% card with a 3% fee clears it in 21 months for about £107 in fees and interest, instead of £1,030 in interest.
How is credit card interest worked out?
Providers charge interest daily on your balance and add it each month. This calculator uses the APR ÷ 12 each month, which is very close. If you pay your full balance by the due date, you usually pay no interest on purchases.
Where can I get free help with debt?
If you’re struggling, free and confidential help is available from MoneyHelper, StepChange and Citizens Advice. Contact your card provider early too: they must treat customers in financial difficulty fairly.
