- ; This example file shows how to solve compound interest problems.
- ;
- ; The compound interest formula is
- ;
- ; future_value = present_value * (1 + interest_rate) ^ n
- ;
- ; First create a user-defined function for future value
-
- fv(pv,i,n) = pv * (1 + i) ^ n
-
- ; Now you can use this function to compute future values with
- ; different parameter values.
-
- ; If $1000.00 is invested at 7% interest compounded annually, what
- ; will be the value at the end of eight years?
-
- future_value = fv(1000.00, 0.07, 8)
-
- ; The answer is displayed and also stored in the variable future_value
- ; for later use in other expressions.
