Thread: Why is this not working?

Hi all,
I have to write a program that uses this equation:
Untitled1.png

when you type in the numbers 7500, 14.5, and 36 you should get:

The amount I wish to borrow is? 7500
The loan rate I can get is? 14.5
The number of months it will take me to pay off the loan is? 36

Why doesnt it work? Heres the code:

import java.io.*;
import java.util.*;
public class Prog58i
{
public static void main (String[] args)
{
//input
System.out.print("the amount I wish to borrow is? ");
Scanner a = new Scanner(System.in);
double borrow = a.nextDouble(); //P
System.out.print("The loan rate I can get is? ");
Scanner b = new Scanner(System.in);
double rate = b.nextDouble(); //R
System.out.print("The number of months it will take me to pay of this loan is? ");
Scanner c = new Scanner(System.in);
double months = c.nextDouble(); //M

//Processing
double MP = borrow * (rate/1200) * Math.pow((1+rate/1200), months) / (Math.pow((1+rate/1200), months)- 1);
double intrest = (MP * months) - borrow;
double repaid = (MP*months);
//Output

System.out.print( "My monthly payments will be $" +MP +"\n");
System.out.print( "Total Interest Paid is $" +intrest +"\n");
System.out.print( "Total Amount Paid is $" +repaid +"\n");


Im very new to Java so please make the answers as simple as possible. Thanks

Never mind I got it to work. The problem I was having was that the output kept coming out as 0.0 instead of 283.17.
The problem was that there was an error in the typing of the formula. It should have been:

double MP = borrow * (rate/1200) * (Math.pow((1+rate/1200), months)) / (Math.pow((1+rate/1200), months)- 1);

Instead of:

double MP = borrow * (rate/1200) * Math.pow((1+rate/1200), months) / (Math.pow((1+rate/1200), months)- 1);


Thanks for the fast reply though
