Compounding in action: Case studies of successful investors

The power of compounding interest can help investments grow exponentially over time. Take a look at some hypothetical examples of using compounding to build significant wealth through mutual funds in India.

What is compounding interest?

Compounding interest is when the interest earned gets added back to the principal amount, so that interest is earned on top of interest over time.  For example, if you invest Rs. 1 lakh at 8% interest, in the first year you will earn Rs. 8,000 interest. In the second year, your interest will be 8% of Rs. 1,08,000 (the original principal plus first year interest). This cycle continues, allowing your money to grow faster.

Case Study 1: Starting early for powerful compounding

Suresh opened a retirement mutual fund account when he started his first job at 22. He invested Rs. 5,000 per month in equity funds earning 12% returns on average.  After 35 years of monthly investments, Suresh had put in a total of Rs. 21 lakhs of his own money. But thanks to the power of compounding, his investment corpus grew to Rs. 4.1 crores. 

The key was starting early and giving his investments decades to compound. Suresh also planned when using a compound interest calculator. Suresh's consistent investments and the compounding of returns allowed his corpus to grow exponentially.

Case Study 2: Investing lump sums for big gains

Deepa received Rs. 50 lakhs as an inheritance when she was 45 years old. She invested the lump sum into a mix of equity and debt mutual funds. Over the next 20 years, her mutual fund investment grew at an average of 10% annual returns. Thanks to compound interest, her Rs. 50 lakh lump sum grew to over Rs. 3 crores by the time she was 65. Deepa's large initial investment amount, coupled with two decades of compounding returns, helped multiply her wealth significantly.

Case Study 3: Reinvesting gains to speed up compounding

Akash started investing Rs. 10,000 per month into an equity fund through SIP at age 30. He selected the dividend reinvestment option, so all dividend payouts from the fund would be re-invested.

After 25 years, Akash had invested Rs. 30 lakhs of his own money. But his investment corpus grew to Rs. 1.2 crores. The dividend reinvestment allowed compounding to have an even bigger impact.

These examples show how ordinary can investors use the extraordinary power of compounding to grow their wealth substantially over time. Harnessing compound interest and giving your money decades to compound can help you build your dream corpus and achieve financial independence.
