### Example: Future Value of an Investment

A couple starts setting aside $30,000 a year when they are 45 years old. They expect to earn 5% interest on the money compounded yearly. The future value of the investment is computed for a 20 year period.
import com.imsl.finance.*;
import java.text.NumberFormat;
public class fvEx1 {
public static void main(String args[]) {
double rate = .05;
int nper = 20;
double payment = -30000.00;
double pv = -30000.00;
int when = Finance.AT_BEGINNING_OF_PERIOD;
double fv = Finance.fv(rate, nper, payment, pv, when);
System.out.println("After 20 years, the value of the investments "
+ "will be " + NumberFormat.getCurrencyInstance().format(fv));
}
}

#### Output

After 20 years, the value of the investments will be $1,121,176.49
