Further information


This website is designed to help you to explore how much it costs to use a credit card. It allows you to say how much you owe on the credit card, whether you intend to use it further and how you plan to repay. It will give you an indication of how much interest you will be charged. However, card providers may use different interest calculations and they may also charge other fees, for example where a customer misses a payment, which are not captured by this website. Annual fees, which in this website are added to the card balance in a single month each year, may also be applied in different ways by different card providers. Small differences between figures shown on the results page may occur due to rounding. Where there is an introductory rate, such as on a balance transfer, you are reminded to come back to this site when this rate ends, to find out how much more your card will cost you.

This all means that our estimates of how much your card will cost you are not guaranteed to be accurate. UK Finance cannot be held liable for any inaccuracies in the estimates produced.

For more information about how interest, fees and other charges are applied, check your statement or contact your card provider.

Monthly statements

Your card provider will either send you a monthly statement by post, or you will be able to view your statement online (if you have registered to do this).

The information that you'll need to get the most out of this website is shown in a 'summary box' shown on the front of your statement.

Clearing your balance

When calculating the cost of your credit card, this website assumes that you want to clear the balance on your credit card. If your repayment amount is not enough to cover the interest charged plus some of your starting balance, or if your ongoing spending is too high, your balance will go up rather than reduce. In this situation, the calculator will not run. To find out how much it will cost to clear the balance on your card, you may need to increase how much you repay or reduce your ongoing spending.
