What is APR?

APR stands for Annual Percentage Rate, but what exactly is that?

It’s about the cost of borrowing

The APR gives you a rough idea about how much your borrowing could cost each year, shown as a percentage. It’s also a handy way to compare credit products quickly.

  • The higher it is, the more expensive it’ll be to borrow. 
  • The lower it is, the cheaper borrowing will be.

Watch our video for a simple explanation of what an APR (Annual Percentage Rate) is.

Here's what APR includes

Interest plus fees equals APR


APR calculations are usually based on your card purchase interest rate.



Annual or application fees are included in the APR calculation.



The estimated cost of borrowing is shown as a percentage – the Annual Percentage Rate.

There is a difference between interest rates and APR

Interest rates account for just one potential cost of having and using a credit card. APR includes other standard fees, meaning it gives you a more complete picture of the costs.

APR doesn’t include all costs

  • Additional fees and charges could apply when using your credit card on a month-to-month basis. Those might include late payment fees, cash advance fees, transfer fees and so on.
  • Interest rates could be higher for other transaction types, such as cash withdrawals and advances. Remember, APR calculations are usually based on the card purchase interest rate only.

What’s a representative APR?

This is the interest rate that at least 51% of applicants are expected to get, although the actual rate and credit limit offered is based on an assessment of your circumstances. The representative APR is usually based on:

  1. A credit limit of £1,200.
  2. Spending the full £1,200 on the first day.
  3. Equal monthly repayments over a year.
  4. No other spending is made.

Why representative APRs are useful

Most lenders provide a representative APR, making it easier for you to compare two or more cards. Things like annual fees could push the APR up, but you might receive additional benefits for those, so make sure you check all of the finer details carefully before choosing a credit card to suit your needs.

  • The APR is useful for making quick comparisons, but you should review all details before making any decisions. The APR is usually based on the card purchase rate only, so if you plan to make transfers or other types of transaction, you’ll need to compare more than just APRs.

    Also consider any fees which might apply as you use your credit card, in addition to any annual or application fees, which are included in the APR calculation. Those could include things like transfer or cash advance fees, and charges for missing payments. Some lenders will also charge for going over your credit limit.
