Credit Card Calculator

We'll help you understand how much you need to pay and how long it will take.

Published on

Our credit card calculator will tell you how long it will take you to pay off your balance with your planned monthly repayment amount, or how much you would need to pay each month to clear the debt sooner.

Have you got a balance sitting on a credit card? Or perhaps you’re about to apply for your first one and want to do a bit of research.

Either way, our handy calculator will help you work out how long it will take you to clear your balance at the interest rate your card charges using different monthly payment amounts.

Alternatively, you can see what monthly repayments you will need to make in order to clear your balance by a certain date. And in either case, you’ll be able to see how much total interest it will cost you. Finally, if you want to be super-organised, you can save your results in a table and compare scenarios.

Our calculator will help you see where you stand. Once you know this, you can search for a card to help you save on your repayments – the right card could help you save more than you think.

Update: coronavirus and credit card debt

The Financial Conduct Authority (FCA) has introduced new rules that mean providers must grant a minimum three-month repayment freeze to anyone struggling to pay their credit card debts.

To apply for a freeze, speak to your provider and make sure you have it officially agreed before stopping any payments. Bear in mind that interest will continue to build up and will be added to later payments – so only take a payment holiday if you really need one. More details here.

How much do you owe on your credit card?


This rate of interest determines how much it costs for you to borrow on the credit card.

You should be able to find it on your statement, usually in a summary box on the back. Unless you have changed cards recently, it's likely to be between about 14.9% and 29.9%.

If you can't find it, get in touch with your card provider - they will be able to tell you simply and quickly.
