Interest is the money you receive for locking-in or lending money. When interest is not compounded, it is called simple interest. And this calculator will help you estimate it. Whether you are taking a loan or putting your money in saving, simple interest calculators are a must-use. Let’s learn more about them below.

A simple interest calculator is a tool to compute the simple interest on loans or savings. It take the principal amount, annual interest rate, and investment period on board. Once these details are in place, the calculator estimates the interest in a few seconds.

When a borrower repays the money they owe, the lender receives a sum of money in addition to the principal amount. (The borrowed amount is known as the principal.) The additional amount the borrower pays for holding on to the money for a specified period is called the interest. To calculate this simple interest, use our calculator. Simply enter the principal amount, the number of periods of investment, and the interest rate, and voila, there you have it—the simple interest.

Alternatively, you could use the formula below.

To calculate simple interest, one must multiply the interest rate by the principal amount and the time in years. As a formula, this may be presented as follows:

**Simple Interest (SI) = P × T × R ⁄ 100**

In the equation above:

P = Initial principal balance

r = Annual interest rate

t = Time (usually in years)

Calculating simple interest with the calculator above is easy and quick. Simply follow the basic few steps below:

**Step 1:** Go to the online SI calculator page.

**Step 2: **Select the interest type as simple interest.

**Step 3**: Enter the principal amount.
