Java Program to Calculate Simple Interest

Simple interest is a method of calculating the interest charge on a loan in banking and economic sectors.

It gets estimated day to day with help of interest rate, principal amount and time.

  • First we create scanner class object to pass input data from user.
  • Integer.parseInt() method convert String data to Integer value.
  • Here we convert principal, time and rate into integer.
  • Now use the Simple Interest formula to calculate the rate.
  • Print the Simple Interest data.

Simple interest formula is :-

Simple Interest = (P x T x R)/100

Here P = principal amount, R = Rate, T = Time (years)

					import java.util.Scanner;

public class SimpleIntrest {
	public static void main(String[] args) {
		int principal, time, rate, SimpleInterest;
		Scanner sc = new Scanner(;
		System.out.println("enter principal,time and rate.....");
		principal = Integer.parseInt(;
		time = Integer.parseInt(;
		rate = Integer.parseInt(;
		SimpleInterest = (principal * time * rate) / 100;
		System.out.println("Simple Intrest is..........: " + SimpleInterest);


Output :-
enter principal,time and rate…..
Simple Intrest is……….: 96
