Simple Interest Calculator

You may recall solving simple interest problems in your math class, but understanding this concept has benefits beyond the classroom. Simple interest helps you figure out how much your investments will grow or what you’ll end up paying on a loan. 

Using a simple interest calculator simplifies this process, making it accessible for everyone, from students to adults. Learn more about how this straightforward formula can make a big impact on your financial literacy.

Share.Market’s simple interest calculator is a handy online tool that helps you quickly calculate the interest earned on an investment. It uses a straightforward formula to determine the interest based on the principal amount, interest rate, and time period. By providing accurate input, you can easily estimate your potential returns.

The formula used is straightforward, but breaking it down will help you clearly see how your principal grows over time with interest. The formula for calculating simple interest is:

A = P(1+rt)

Where:

• A = Total accumulated amount (principal + interest).
• P = Principal amount (the initial amount of money invested or loaned).
• r = Annual rate of interest (expressed as a decimal).
• t = Time period (in years or months).

For just the interest portion, the formula is:

SI = (P×r×t)/100​

Where:

• SI = Simple interest
• P = Principal amount
• r = Rate of interest
• t = Time

This simple interest formula is a valuable tool for calculating interest on loans, investments, and savings accounts. It provides an easy way to estimate how much extra money you’ll have to pay or earn after a set period.

Imagine Mr. B invested Rs. 10,000 at an interest rate of 6% per year for 3 years.

Using the formula:

SI=(P×r×t)/100 ​= (10,000×6×3​)/100 = ₹1,800

In this case, Mr. B will earn a total interest of ₹1,800. His total maturity amount (A), which includes the principal and interest, will be:

A=P+SI = ₹10,000+ ₹1,800 = ₹11,800So, after 3 years, Mr. B’s investment will have grown to ₹11,800.
