Compound Interest Calculator

Looking to invest in new savings or investment plans? Or planning to deposit your earnings in an FD? Whatever your choice is, get the most out of your investments with the power of compounding. Compounding or compound interest is when you add interest to your interest to grow your investments over a period of time; a compound calculator is a handy tool to plan your earnings better.

A compound interest calculator lets you determine how much your investment will grow when you invest a specific sum of money for a fixed period of time on compound interest. A compound interest calculator simplifies the process of calculating your earnings and offers you an accurate estimate. With the power of compounding, you can witness an exponential increase in your investments.

What is Compound Interest?

Simply put, the interest calculated on your initial investment and the cumulative interest determined from the previous periods gives you compound interest. The interest you earn on your initial investment gets added to the principal amount, where the next interest amount is calculated on this new amount, allowing your investment to grow consistently during the investment period.

In other words, compound interest is the 'interest earned on the sum which was previously earned as interest.' The longer you keep your funds invested, the more you will benefit from growing investments as your money keep multiplying over time.

To calculate the future value (FV) of your investment with compound interest, you can use this simple compound formula-

A = P (1 + r/n) nt

To accurately calculate your compound interest earnings, you must know the following-

  • Principal investment amount
  • Expected rate of return on the investment
  • The number of years of investment
  • The number of times the interest is compounded

Or you can simply use the compound interest calculator available on our website to determine your compound earnings. All you need to do is enter your investment amount, the number of years, and the expected rate of returns. And the calculator will help you plan your investments accurately.

How Does Compound Interest Work?

Whether you want to invest funds for your child's education, your family's secure future, or achieve your goal of wealth creation, investing with compound interest allows you to multiply your wealth significantly over time. On the other hand, if you have applied for a loan on compound interest, any delays can increase your interest payments.

The compounding process starts with you earning interest on your principal sum, which is added to the initial investment amount. When your interest is due again, it will consider the new total amount (principal + interest) and add your interest earnings to it. This power of compounding will keep on adding interest to the total investment amount as it continues to grow.

Over time, the compound interest cycle can build your funds substantially over the initial investment. Here are the various factors that determine your compound interest returns-

  • Rate of Interest- Higher the interest rate, the higher the interest amount compounded on your investment
  • Time- Compound formula works to grow your funds over time, so the longer you keep your funds invested, the higher your growth will be

Whatever your investment priorities or financial goals are, you can harness the power of compounding to ensure you can achieve these goals seamlessly.

Compound Interest Formula and How to Calculate Compound Interest

Tata Capital's compound interest calculator uses a simple compound interest formula to arrive at the future value of your investment-

A = P (1 + r/n) nt where,

  • A = Total amount or the future value of the investment
  • P = Principal amount
  • r = Rate of interest
  • n = the number of times interest is compounded in a period
  • t = number of years

You can even use an easy-to-use calculator to calculate compound interest online. Here's an example to help you better understand the compound interest formula.

Say you invest Rs. 20,000 at an annual rate of 5% compounded annually for 5 years.

Year 1

Interest = 20,000 X 5/100 = Rs. 1000; Amount = Rs. 21,000

Year 2

Interest = 21,000 X 5/100 = Rs. 1050; Amount = Rs. 22,050

And so on. Now, using the compound interest formula, your final investment earnings at the end of 5 years become-

A = 20,000 (1 + 0.05)5 = Rs.  25,525 and the interest earnings come to Rs. 20,000
