## Future Value

doublefuture_value( | double | rate | |

int | nper | ||

double | pmt | ||

double | pv | ||

PaymentPoint | when | ) |

*fv*: If rate = 0, If rate /= 0, Where

*pv*is the present value,

*rate*is the interest rate,

*nper*is the number of periods over which to calculate and

*pmt*is the payment made each period. Calculating the future value of an investment according to a scedule of compound interest rates is done using the following equation: Where

*nper*is the number of periods (and in this case entries in the

*shedule*array),

*pv*is the principal value and

*schedule*is an array of compound interest rates.

#include <stdio.h> #include <codecogs/finance/banking/future_value.h> int main() { double d = Finance::Banking::future_value(0.05, 20, -30000, -30000, Finance::Banking::pp_StartOfPeriod); printf("30,000 set aside per year\n"); printf("5%% interest compounded yearly\n"); printf("After 20 years, the value of the investment will be: %7.2f\n\n", d); d = Finance::Banking::future_value(0.00, 7, -50, 0, Finance::Banking::pp_StartOfPeriod); printf("50 set aside per year\n"); printf("no interest\n"); printf("After 7 years, the value of the investment will be: %.2f\n", d); return 0; }

Output:30,000 set aside per year 5% interest compounded yearly After 20 years, the value of the investment will be: 1121176.49 50 set aside per year no interest After 7 years, the value of the investment will be: 350.00

pp_StartOfPeriod or pp_EndOfPeriod.
