Enter 9% and 3 (for 3 months per quarter to get P = 3%, the effective rate per month. Side Note: the effective rate calculation tells us How to calculate annual percentage yield. The calculation of the annual percentage yield is based on the following equation: APY = (1 + r/n) n – 1. where: r - the interest rate; n - the number of times the interest is compounded per year; As you have already learned what APY is, you can use this formula to calculate the annual percentage yield by yourself.
