##### Turbo C Program to Calculate Compound Interest
« on: December 29, 2011, 01:17:23 pm »
Here is the Turbo C Program to Calculate Compound Interest.

The formula for calculating  Compound Interest is given below:

FV   =   P * (1  +  r / n)Y*n

where

FV - Future Value
P - Present Value (principal amount)
r - Interest rate
n - number of times the interest is calculated per year
Y - number of years

Code:
```//Source Code Listing

#include <stdio.h>
#include <math.h>

void main()
{
double amount;
double years;
double interest_rate;
double numtimes;
double compound_interest;

printf("Program to Calculate Compound Interest");

printf("Enter Principal Amount:");
scanf("%lf",&amount);

printf("Enter Number of Years:");
scanf("%lf",&years);

printf("Enter Interest Rate:");
scanf("%lf",&interest_rate);

printf("Enter the number of times the interest is compounded per year: ");
scanf("%lf",&numtimes);

compound_interest = amount * pow( (1 + (interest_rate / 100) / numtimes ), numtimes * years);
printf("Future Value after Compound Interest = %lf\n",compound_interest);
}

/***
Sample Output:

Program to Calculate Compound InterestEnter Principal Amount :1000
Enter Number of Years:5
Enter Interest Rate:5
Enter the number of times the interest is compounded per year: 2
Future Value after Compound Interest = 1280.084544

***/
```
