What is compounding?

Compounding is a powerful financial concept that can help your investments grow at an accelerated rate with time. Compounding happens when the interest or returns you earn on your principal are reinvested and go to earn further interest/return. As a result, your base or principal amount keeps growing. This cycle continues throughout your investment period and can result in a snowball effect that can potentially create wealth over time.

Let’s see the effect of compounding through an example. Assume that you make a one-time investment of Rs. 10,000 for a period of 10 years at an annual interest rate of 10%. Without compound interest, you will earn interest only on the principal amount, which means you will earn Rs 1,000 a year. Over 10 years, you would have earned Rs 10,000 on an investment of the same amount, which amounts to Rs 20,000.

Now, let's consider the same investment with compounding. In this case, you will earn interest not only on the principal amount but also on the accumulated interest. So, your principal of Rs. 10,000 will earn 10% interest in the first year. Your total principal for the next year will now be Rs 10,100 on which an additional 10% will be earned, and so on. At the end of the compounding period, your corpus will grow to approximately Rs. 26,000. This is significantly higher than the returns in the first scenario.

Visualising growth with compounding calculator

When you are investing, especially in small amounts, it can be difficult to visualise the return potential on your investments. This could even lead to inconsistency in investing or the temptation to pause, stop or reduce your investments.

A compounding calculator can help you stay invested in such times by showing you the projected potential returns on your investments. When you enter the principal amount, interest rate or estimated rate of return, and investment horizon, the calculator shows you the projected return on your investment.

How to use a compounding calculator

Bajaj Finserv AMC has a free online compounding calculator. To use it, follow these steps:

  • Enter the principal amount: This is the initial amount you are investing.
  • Enter the interest rate: This is the expected rate of annual compound interest you can earn on your investment.
  • Enter the compounding frequency: This is the number of times interest is compounded in a year. The most common compounding frequencies are monthly (12 times a year), quarterly (4 times a year), and annually (once a year).
  • Enter the investment horizon: This is the number of years you plan to hold the investment.
  • Click on ‘calculate’. The compounding calculator will then provide you with the projected returns on your investment.

Do note that the calculator assumes a fixed interest rate, whereas returns on your mutual fund investment will depend on market conditions and may fluctuate.

Compounding happens when the interest earned on the principal amount is reinvested and further interest is earned on both the principal and the previously accumulated interest. This process continues, resulting in exponential growth over time.
