What does credit card APR mean?

APR stands for annual percentage rate and is used to calculate the cost of lending on financial products.
Due to the inclusion of charges, APR can be somewhat difficult to understand; the interest rate may be 14 per cent, but the APR could be 17 per cent as the fees would total another 3 per cent per annum.
You shouldn’t assume that a lower APR means a better deal, as lenders calculate interest differently and may have other fees.
There are two common types of APR, personal and representative. Representative APR tends to be used on products where the interest rate offered will be dependent on your credit score.
Personal APR is a rate that stays the same regardless of your credit score.
