Program to find simple interest

Last Updated : 18 Dec, 2024

Given Principal p, Rate r and Time t, the task is to calculate Simple Interest.

Examples :

Input: p = 10000, r = 5, t = 5
Output:2500
Explanation: We need to find simple interest on Rs. 10,000 at the rate of 5% for 5 units of time.
Input: p = 3000, r = 7, t = 1
Output:210

The basic idea is to calculate by applying the formula SI = (p x t x r)/100

C++

// CPP program to find simple interest for
// given principal amount, time and rate of interest
#include<iostream>
using namespace std;

float simpleInterest(float p, float t, float r){
    /* Calculate simple interest  */
    float ans = (p * t * r) / 100;
    return ans;
}

int main() {

    float p = 1, r = 1, t = 1;
    cout <<simpleInterest(p,r,t);

    return 0;
}

#include <stdio.h>

float simpleInterest(float p, float t, float r) {
    /* Calculate simple interest  */
    float ans = (p * t * r) / 100;
    return ans;
}

int main() {
    float p = 1, r = 1, t = 1;
    printf("%f", simpleInterest(p, r, t));
    return 0;
}

Java

class GfG {
	static float simpleInterest(float p, float t, float r) {
        /* Calculate simple interest  */
        return (p * t * r) / 100;
    }

    public static void main(String[] args) {
        float p = 1, r = 1, t = 1;
        System.out.println(simpleInterest(p, r, t));
    }
}

Python

def simpleInterest(p, t, r):
    /* Calculate simple interest  */
    return (p * t * r) / 100

if __name__ == "__main__":
  p = 1
  r = 1
  t = 1
  print(simpleInterest(p, r, t))

using System;

class GfG {
    public static float SimpleInterest(float p, float t, float r) {
        /* Calculate simple interest  */
        return (p * t * r) / 100;
    }

    static void Main() {
        float p = 1, r = 1, t = 1;
        Console.WriteLine(SimpleInterest(p, r, t));
    }
}

JavaScript

function simpleInterest(p, t, r) {
    /* Calculate simple interest  */
    return (p * t * r) / 100;
}

//driver code
let p = 1, r = 1, t = 1;
console.log(simpleInterest(p, r, t));

Output

0.01
