What is the full form of "APR"?

Annual percentage rate (APR) refers to the yearly interest generated by a sum that's charged to borrowers or paid to investors. APR is expressed as a percentage that represents the actual yearly cost of funds over the term of a loan or income earned on an investment. This includes any fees or additional costs associated with the transaction, but it does not take compounding into account. The APR provides consumers with a bottom-line number they can compare among lenders, credit cards or investment products.
