This is interest that is calculated on both the principal and accrued interest at scheduled intervals. The formula we use to find compound interest is A = P (1 + r/n)^ nt. In this formula, A stands for the total amount that accumulates. P is the original principal; that's the money we start with. The r is the interest rate. We convert the percent to a decimal for this one.
