**Annual percentage rate (APR)** is the periodic rate times the number of periods in a year. For example, a 5% quarterly return has an APR of 20%.

There are many ways of calculating the **annual rate of return**. If the rate of return is calculated on a monthly basis, we sometimes multiply this by 12 to express an annual rate of return. This is often called the **annual percentage rate (APR)**. The annual percentage yield (APY), includes the effect of compounding interest.
