In this blog, we’ll introduce you to a simple interest calculator and show you how it works.

What is Simple Interest?

Before we understand the workings of a simple interest calculator, let’s briefly understand what is simple interest

Simple interest is a way to calculate how much you earn or owe on a principal amount over time. It is calculated by taking into account three factors: the principal (the initial amount of money), the interest rate (a percentage of the principal), and the time period (usually in years). Simple interest does not take into account any interest that accumulates on previously earned interest.

What is a Simple Interest Calculator?

A simple interest calculator is an online tool that allows users to quickly calculate the amount of simple interest they will earn or owe based on their inputs. It saves time and reduces the chances of calculation errors.

How Does a Simple Interest Calculator Work?

To use a simple interest calculator, you must follow these steps:

  1. Enter the Principal Amount: Input the initial amount of money you are borrowing or investing.
  2. Input the Interest Rate: Provide the interest rate as a percentage. The calculator often converts this to decimal form automatically.
  3. Specify the Time Period: Indicate how long the money will be borrowed or invested (usually in years).
  4. Click Calculate: After entering all the information, click the “Calculate” button. The calculator will then display the simple interest amount.

A simple interest calculator helps you find the total amount, which includes both the principal and interest.

Now, how to calculate simple interest on loan and what is the formula of simple interest?

Let us take a look at the simple interest formula!

A = P (1 + rt)

Where:

  • P = Initial amount (Principal)
  • r = Interest rate
  • t = Time in years
  • A = Total amount (Principal + Interest)
  • Interest = A – P (Difference between total amount and principal)

Let’s break it down with an example.

Suppose the principal amount is Rs 15,000, the interest rate is 8%, and the time period is five years. The simple interest would be:

A = 15,000 (1 + 0.08 * 5) = Rs 21,000

Simple Interest will be

A – P = 21,000 – 15,000 = Rs 6,000.
