Program to find compound interest in C++

In this tutorial, we will be discussing a program to find compound interest.

Compound interest is the interest by adding the current interest to the principal sum and then calculating the interest on the updated amount.


 Live Demo

#include <bits/stdc++.h>
using namespace std;
int main(){
   double principle = 10000, rate = 10.25, time = 5;
   //calculating compound interest
   double CI = principle * (pow((1 + rate / 100), time));
   cout << "Compound interest is " << CI;
   return 0;


Compound interest is 16288.9
