Find the amount P that needs to be invested at 4.275% compounded annually for 5 years to give a final amount of $3000. (This amount P is also called the present value of the future amount of $3000 in 5 years.)

In the examples that follow, note that while the applications are drawn from many different disciplines, the mathematics remains essentially the same. Due to the applied nature of the problems we will examine in this section, the calculator is often used to express our answers as decimal approximations.

This could be a starting investment, or the starting amount of a loan. Interest, in its most simple form, is calculated as a percent of the principal.

The total amount you would repay would be $105, the original principal plus the interest. The units of measurement (years, months, etc.) for the time should match the time period for the interest rate. Interest rates are usually given as an annual percentage rate (APR) – the total interest that will be paid in the year.

The amount of money that is being borrowed or loaned is called the principal or present value. Simple interest is paid only on the original amount borrowed. When the money is loaned out, the person who borrows the money generally pays a fixed rate of interest on the principal for the time period he keeps the money.

To find the total change, we would subtract the original amount, then to find the percentage change we would divide that by the original amount:
