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....
If you want the return value to return two decimal places, enclose the formula with the correct Round function: Round(Current Formula;2).
