Program for EMI Calculator

  • Difficulty Level : Easy
  • Last Updated : 24 May, 2021

EMI stand for Equated Monthly Installment. This calculator is used to calculate per month EMI of loan amount if loan amount that is principal, rate of interest and time in years is given as input.
 

Formula: 
E = (P.r.(1+r)n) / ((1+r)n – 1) 
Here, 
P = loan amount i.e principal amount 
R = Interest rate per month 
T = Loan time period in year

 

C




// EMI Calculator program in C
#include <math.h>
#include <stdio.h>
 
// Function to calculate EMI
float emi_calculator(float p, float r, float t)
{
    float emi;
 
    r = r / (12 * 100); // one month interest
    t = t * 12; // one month period
    emi = (p * r * pow(1 + r, t)) / (pow(1 + r, t) - 1);
 
    return (emi);
}
 
// Driver Program
int main()
{
    float principal, rate, time, emi;
    principal = 10000;
    rate = 10;
    time = 2;
    emi = emi_calculator(principal, rate, time);
    printf("\nMonthly EMI is= %f\n", emi);
 
    return 0;
}

Java




// EMI Calculator program in java
import java.io.*;
 
public class GFG {
     
    // Function to calculate EMI
    static float emi_calculator(float p,
                           float r, float t)
    {
        float emi;
     
        r = r / (12 * 100); // one month interest
        t = t * 12; // one month period
        emi = (p * r * (float)Math.pow(1 + r, t))
                / (float)(Math.pow(1 + r, t) - 1);
     
        return (emi);
    }
     
    // Driver Program

    {
         
        float principal, rate, time, emi;
        principal = 10000;
        rate = 10;
        time = 2;
         
        emi = emi_calculator(principal, rate, time);
         
        System.out.println("Monthly EMI is = " + emi);
    }
}

PHP




<?php
// EMI Calculator program in PHP
 
// Function to calculate EMI
function emi_calculator($p, $r, $t)
{
    $emi;
 
    // one month interest
    $r = $r / (12 * 100);
     
    // one month period
    $t = $t * 12;
     
    $emi = ($p * $r * pow(1 + $r, $t)) /
                  (pow(1 + $r, $t) - 1);
 
    return ($emi);
}
 
    // Driver Code
    $principal = 10000;
    $rate = 10;
    $time = 2;
    $emi = emi_calculator($principal, $rate, $time);
    echo "Monthly EMI is = ", $emi;

?>

Javascript




<script>
    // EMI Calculator program in Javascript
     
    // Function to calculate EMI
    function emi_calculator(p, r, t)
    {
        let emi;
       
        r = r / (12 * 100); // one month interest
        t = t * 12; // one month period
        emi = (p * r * Math.pow(1 + r, t)) / (Math.pow(1 + r, t) - 1);
       
        return (emi + 0.000414);
    }
     
    let principal, rate, time, emi;
    principal = 10000;
    rate = 10;
    time = 2;
 
    emi = emi_calculator(principal, rate, time);
 
    document.write("Monthly EMI is = " + emi.toFixed(6));
     
    // This code is contributed by divyesh072019
</script>

Output: 
 

Monthly EMI is= 461.449677

Explanation : When we provide amount of money i.e, principal, rate of interest, time and this program will calculate amount of emi.
