Compound Interest Formula

Amount=P(1+r/100)^t

P=Principal Amount
r=Rate of Interest
t=Time Periods.

Program to Find Compound Interest Using C Programming

#include<stdio.h>
#include<math.h>
int main()
{
	int principal_amount,rate_of_interest,Interest_applied,time_periods;
	printf("\n\n\tProgram to Find Compound Interest Using C Programming.");
	printf("\n\tEnter Principal Amount.");
	scanf("%d",&principal_amount);
	printf("\n\tEnter Rate of Interest.");
	scanf("%d",&rate_of_interest);
	printf("\n\tEnter Time Periods.");
	scanf("%d",&time_periods);
	float compond_interest=principal_amount*pow((1+(rate_of_interest/100)),time_periods);
	printf("\n\tCompound Interest is: %lf\n\n\n",compond_interest);
	return 0;
}

Output

Program to Find Compound Interest Using C Programming.
	Enter Principal Amount.2000

	Enter Rate of Interest.2

	Enter Time Periods.3

	Compound Interest is: 2000.000000

Code Explanation

First, ask the user to input Principal Amount, Rate of Interest, Time Period.

Store the input values to variables using scanf() function.

In the program using the formula compound interest is calculated and stored in compound interest variable.

Print the output.
