.

## Example 1

Your cousin borrowed $2,000 from you, offering to pay you back $500 a year for five years, for a total of $2,500 at the end of five years. If inflation was 5 percent annually, with the following entry you could find out what those payments are worth with the PV function.

`PV(500;.05;5)`

returns **2164.73833531...**.
