Understand the 8:4:3 rule and the rule of 72; maximize the growth of your mutual fund investment

When it comes to mutual fund investments, there are two key principles that can have a significant impact on your financial growth: the 8:4:3 rule and the rule of 72. Let’s dive deeper into these concepts to understand how they can help you optimize your investments and achieve long-term wealth.

What is the 8:4:3 rule?

The 8:4:3 rule is a time-tested strategy designed to help investors visualize the growth of their mutual fund investments. This rule is based on the principle of compound interest and suggests that if you invest in a mutual fund with an annual return of 12%, your investment will double approximately every 8 years. After the first doubling, it will double again in the next 4 years and then one last time in the subsequent 3 years.

Applying the 8:4:3 rule means your mutual fund investment will quadruple in 15 years and eightfold in 21 years. This approach highlights the potential for compounding over time, offering a clear path to substantial growth.

The power of capitalization

Compound interest is a critical factor in the growth of your investments. When you earn interest on both the initial principal and the interest that accrues, your money grows exponentially. For example, if you deposit Rs 100 at an annual interest rate of 10%, you will have Rs 110 after one year. The following year, you earn 10% interest on Rs 110, bringing your total to Rs 121, and this process continues annually, resulting in astonishing growth over time.

The Rule of 72: How Will Your Money Grow?

The Rule of 72 is a simple tool to calculate how long it will take for your investment to double. By dividing 72 by the annual interest rate, you can determine the number of years required for your money to double. For example, if you invest Rs 100 at an annual interest rate of 10%, the calculation is 72/10 = 7.2 years. This means that your investment will double in approximately 7.2 years.

For a larger investment like Rs 1,00,000, it will turn into Rs 2,00,000 in about 7 years if you maintain continuous investment and potentially increase your contributions.

How to Become a Millionaire: How Early Investing Pays Off

To build significant wealth for retirement, start investing as early as possible. For example, if you invest Rs 5,000 per month from the age of 25 at an annual return of 10%, you could have a fund of over Rs 100 crore by the age of 60. This highlights the importance of investing early and consistently.

When will your money triple or quadruple?

• Rule of 114: To calculate when your money will triple, divide 114 by the annual interest rate. For an 8% return, 114/8 = 14.25 years. So your money will triple in about 14.25 years.
• Rule of 144: To determine when your money will quadruple, divide 144 by the annual interest rate. At an 8% return, 144/8 = 18 years. So your money will quadruple in about 18 years.

Recent investment regulations

The new regulations on mutual fund investments include mandatory nominations, linking of PAN and Aadhaar numbers, requirement of one-time passwords and revalidation of KYC information. These updates are aimed at improving the efficiency and security of the investment process.

Benefits of the 8:4:3 rule
