A simple interest calculator is a useful tool that helps you calculate the interest earned or paid on a principal amount for a specified period of time. The concept of simple interest is one of the most basic principles of finance and is used in many different applications, including loans, investments, and savings accounts. In this article, we will discuss what simple interest is, how it works, and how you can use a simple interest calculator to calculate the interest on your investments, loans, or savings accounts.

## What is Simple Interest?

Simple interest is the amount of interest earned or paid on a principal amount over a specified period of time. Unlike compound interest, which is calculated on both the principal amount and the accumulated interest, simple interest is calculated only on the principal amount. The formula for calculating simple interest is as follows:

Simple Interest = \text{Principal} \times \text{Rate} \times \text{Time Where :}

Principal is the amount of money you have borrowed or invested.

Rate is the interest rate expressed as a percentage.

Time is the length of time the money has been borrowed or invested, expressed in years.

For example, if you borrow $1,000 at an annual interest rate of 5% for 2 years, the simple interest would be calculated as follows:

Simple Interest = \$1,000 \times 5\% \times 2 \text{ Years} \= $100

This means that you would have to pay $1,100 at the end of the 2-year period, consisting of the original principal amount of $1,000 plus the simple interest of $100.

## How does Simple Interest Calculator work?

A simple interest calculator is a tool that helps you calculate the interest on a principal amount over a specified period of time. The calculator uses the formula for simple interest to determine the amount of interest earned or paid on a principal amount.

To use a simple interest calculator, you need to enter the following information:

Principal: This is the amount of money you have borrowed or invested.

Rate: This is the interest rate expressed as a percentage.

Time: This is the length of time the money has been borrowed or invested, expressed in years.

Once you enter this information, the calculator will automatically calculate the amount of interest earned or paid on the principal amount.
