# Kotlin program to calculate simple interest

Kotlin | Simple Interest: Here, we are implementing a Kotlin program to calculate the simple interest.
Submitted by IncludeHelp, on May 12, 2020

Given, principal, rate, and time, we have to calculate the simple interest.

Formula to calculate simple interest is: (P × R × T)/100

Where,

• P is Principal amount.
• R is rate of interest per annum.
• T is time in years.

Example:

```    Input:
P = 5000
R = 12
T = 2

Output:
Simple Interest = 1200.0
```

### Program to calculate simple interest in Kotlin

```package com.includehelp

import java.util.*

//Main Function , Entry point of Program
fun main(args: Array<String>) {

//Input Stream
val scanner = Scanner(System.`in`)

//Input Amount
print("Enter Principal Amount : ")
val principalAmount = scanner.nextDouble()

//Input Interest Rate
print("Enter Rate of Interest : ")
val rateOfInterest = scanner.nextDouble()

//Input time in years
print("Enter Time : ")
val time = scanner.nextInt()

//Calculate Simple Interest
val simpleInterest = (principalAmount*rateOfInterest*time)/100

//Print Simple Interest
println("Simple Interest is :\$simpleInterest")
}
```

Output

```Run 1:
Enter Principal Amount : 5000
Enter Rate of Interest : 12
Enter Time : 2
Simple Interest is :1200.0
---
Run 2:
Enter Principal Amount : 500.60
Enter Rate of Interest : 12.56
Enter Time : 5
Simple Interest is :314.37680000000006
