APR stands for annual percentage rate. APR is a broader calculation than interest rate because it also includes certain lending fees. The APR is designed to tell you the true cost of borrowing as it includes loan origination fees, broker fees, annual fees and certain other funding costs. Always check the APR in addition to the stated interest rate. The APR can run very high on certain financing products. For example, advances on credit cards could easily have an APR of 20% to 25%. For certain short term loans, lines of credit or personal signature loans, the APR could run as high as 100%!
