Understanding the 8:4:3 Rule
- The 8:4:3 rule helps visualise how your mutual fund investments grow over time through compounding.
- It states that with a 12% annual return, your investment doubles every 8 years, then again in 4 years, and a final time in 3 years.

The Power of Compounding
- Compounding allows your investment to grow exponentially by earning interest on both your principal and accumulated interest.
- For example, an investment of Rs 100 at 10% annual interest grows to Rs 121 after two years, continuing to multiply annually.

Applying the Rule of 72
- The Rule of 72 estimates how long it will take for your investment to double.
- Simply divide 72 by the annual interest rate. For example, at a 10% rate, your investment will double in about 7.2 years.

Tripling and Quadrupling Your Money
- Rule of 114: Divide 114 by the interest rate to estimate when your investment will triple. At 8%, this takes about 14.25 years.
- Rule of 144: To estimate when it will quadruple, divide 144 by the rate. At 8%, your investment quadruples in about 18 years.
