As with simple interest, at the end of the year, I owe A(1) = (1+i)P dollars. Example. This is simple interest. An important part of any such class is learning to use mathematical tools in modeling and estimation. The compound interest is calculated by the formula: () = (1 +) () −the amount after years. If you invest P dollars at the annual interest rate r, then after one year the interest is I = rP dollars, and the total amount is A = P + I = P(1 + r).

Suppose, for example, that I borrow P dollars at rate i, compounded yearly. For compound interest, the year is divided into k equal time periods and the interest is calculated and added to the account at the end of each period once a year, every month, etc.); at the end of each payment period, interest is earned on principal and on previously earned interest.
