The APR Calculator is used to calculate the annual percentage rate (APR).
The annual percentage rate (APR) describes the interest rate for a whole year, rather than just a monthly rate, as applied on a loan, mortgage loan, car loan, credit card, etc. APR is the equivalent interest rate considering all additional costs charged on a certain loan amount. It is a function of the loan amount, interest rate, total additional cost, and the terms. If there are no added costs to a given loan, the APR would equal the interest rate.
