Power of Compounding

The interest in mutual funds is calculated on the basis of Compound Interest. In mutual funds, Compound interest is simply the addition of interest earned, to the principal, which is then reinvested or in other words, interest on interest. Yes, through a compound interest in mutual funds, not only your invested money earns interest for you, but rather the interest earned on your investment also earns interest for you. This is, Compound interest was named as the eighth wonder of the world by a famous scientist, Albert Einstein.

What is 15*15*15 Rule in Mutual Funds?

The rule of 15*15*15 is a very easy rule to understand and much helpful to build a corpus of 1 crore. It is said in mutual funds, that a SIP (Systematic Investment Plan) of Rs 15000 per month at an assumed CAGR (Compounded Annual Growth Rate) of 15% for 15 years can yield a return of 1 crore, on maturity, that is with a total investment of Rs 27 Lakhs, spread across 15 years can fetch its investor Rs 1 crore.

Well, here I am giving a figure that will help you to understand the 15*15*15 rule, graphically.

What Is 15*15*30 Rule in Mutual Funds?

As per this rule, in mutual funds, a SIP (Systematic Investment Plan) of Rs 15000, at an assumed CAGR of 15% for 30 years, can yield a return of Rs 10 crore, on maturity, that is by increasing your investment tenure by 15 years, and with a total investment of Rs 54 Lakhs, you can create a corpus of Rs 10 crores.

Well, here I am giving a figure that will help you to understand the 15*15*30 rule, graphically.

Well, till now you must have understood why Compound interest is known as the eighth wonder of the world, and how its magic works. Do remember 15% CAGR means a 15% average return over a period of time and not a 15% annual return. One can experience a 20% return one year and -5% the next year, because of fluctuations in the market. The average will be 15% over the period of time, one has invested for.

As of now, you benefit from compound interest, I would strongly recommend, start investing through SIP in mutual funds. SIP investment not only give benefits of compounding, but it has other benefits too, like

  1. Rupee Cost Averaging helps the investor to buy more units when the market is low and accumulating more units will help you earn a big return.
  2. It creates a regular and disciplined habit of investing.
  3. It is easy and simple to monitor your SIP investments; you can track them in your bank statements.
  4. SIP’s can be stopped at any time at one’s convenience. The SIP can be paused, or the SIP amount can be increased or decreased at any time during the SIP’s tenure.

Most importantly, always consult a financial planner or advisor, before starting your investments. They will help you select the best fund, for your investments as per your requirement.
