Here you will get C program to calculate compound interest.

The program asks user to enter value of principle (p), rate (r) and time (t) and finally calculates the compound interest by following formula.

Compound Interest = Principle * (1 + Rate / 100) ^{time}

## C Program to Calculate Compound Interest

1 2 3 4 5 6 7 8 9 10 11 12 |
#include<stdio.h> #include<math.h> void main() { float p,r,t,ci; printf("Enter Principle, Rate and Time: "); scanf("%f%f%f",&p,&r,&t); ci=p*pow((1+r/100),t); printf("Bank Loans Compound Interest = %f%",ci); } |

**Output**

*Enter Principle, Rate and Time: 2000*

*2*

*3*

*Bank Loans Compound Interest = 2122.415771*

Is pow is imp in this program. What is pow ??
