In this post, we will learn **how to calculate simple interest** using Java Programming language. Let’s understand about **Simple Interest **and **“how to calculate Simple Interest”** so that we can code the **Java Program to Calculate Simple Interest.**

**What is Simple Interest ?**

**Simple Interest **is an easy and quick method to calculate interest on money. **Simple Interest **is calculated by multiplying the Principle amount by the rate of interest and the time period.

**Simple Interest Formula**

The Formula for simple interest is as follows:

**SI = (P * R * T) / 100**

where SI = **Simple Interest**

P = **Principal Amount**

R = **Rate of Interest in Percentage**

T = **Time Period**

**Java Program to Calculate Simple Interest**

import java.util.*; public class Main{ public static void main(String[] args){ Scanner sc = new Scanner(System.in); System.out.println("Enter the Principle : "); double P = sc.nextDouble(); System.out.println("Enter the Rate of Interest : "); double R = sc.nextDouble(); System.out.println("Enter the Time Period : "); double T = sc.nextDouble(); //Calculating the SI double SI = (P * R * T)/100; System.out.println("Simple Interest calculated is "+SI); } }

**Output**

`Enter the Principle : `**12000**
Enter the Rate of Interest : **5.5**
Enter the Time Period : **10**
**Simple Interest calculated is 6600.0**

**How Does This Program Work ?**

Scanner sc = new Scanner(System.in); System.out.println("Enter the Principle : "); double P = sc.nextDouble(); System.out.println("Enter the Rate of Interest : "); double R = sc.nextDouble(); System.out.println("Enter the Time Period : "); double T = sc.nextDouble();

In this program, we first take the input of **Principle, Rate of Interest, Time Period** and stored them into variables **P, R, T** of **double** datatype respectively. The input is taken by using **Scanner Class** in Java.

//Calculating the SI double SI = (P * R * T)/100;

Then, we calculate the Simple Interest using the formula discussed above.

i.e. **SI = ( P * R * T ) / 100**

System.out.println("Simple Interest calculated is "+SI);

Then, we just display the Simple Interest result using the

function. This is the **System.out.println()****Java Program to Calculate Simple Interest.**
