Compound Interest Calculator

Compound interest is the interest calculated on both the initial principal and the accumulated interest from previous periods. Unlike simple interest, which is only calculated on the original amount of money, compound interest grows over time because it adds interest to the principal as well as any interest that has already been earned.
