# FutureValue Command

From GeoGebra Manual

- FutureValue( <Rate>, <Number of Periods>, <Payment>, <Present Value (optional)>, <Type (optional)> )
- Returns the future value of an investment based on periodic, constant payments and a constant interest rate.

**<Rate>**Interest rate per period.**<Number of Periods>**Total number of payment periods in an annuity.**<Payment>**The amount paid in each period.**<Present Value (optional)>**Total amount that a series of future payments is worth now. If you do not enter a value, it is assumed to be 0.**<Type (optional)>**Indicates when payments are due. If you do not enter a value or you enter 0 the payment is due at the end of the period. If you enter 1 it is due at the beginning of the period.

**Example:**`FutureValue(10%/12, 15, -200, 0, 1)`

yields a future value of 3207.99.**Note:**Make sure that you are consistent about the units you use for`<Rate>`

and`<Number of Periods>`

. If you make monthly payments on a four-year loan at an annual interest rate of 10 percent, use 10%/12 for rate and 4*12 for number of payments.

**Note:**For all arguments, cash paid out is represented by negative numbers and cash received by positive numbers.
