If you're aiming to double, triple, or quadruple your investment, it requires more than just luck—it takes strategic planning, patience, and disciplined investing. While no investment is risk-free, using time-tested formulas can help you make smarter financial decisions and estimate how long it will take to grow your money based on the expected rate of return.

Let’s explore some essential formulas that every investor should know: the Rule of 72, 114, and 144. These simple mathematical tools can guide you in setting realistic financial goals and choosing the right investment strategy.

1. The Rule of 72 – Double Your Investment

The Rule of 72 is a popular formula used to estimate how long it will take to double your investment at a fixed annual rate of return.

Formula:

72 ÷ Rate of Return = Time (in years) to double your money

Example:

Suppose you invest ₹1,00,000 in an instrument offering 8% annual return.

Using the formula:
72 ÷ 8 = 9 years

This means your ₹1 lakh will become ₹2 lakh in 9 years.

2. The Rule of 114 – Triple Your Investment

To determine how long it will take to triple your money, financial experts use the Rule of 114. The concept is similar to the Rule of 72 but uses 114 instead.

Formula:

114 ÷ Rate of Return = Time (in years) to triple your money

Example:

If your investment gives you a 10% annual return,
114 ÷ 10 = 11.4 years

So your ₹1 lakh investment will become ₹3 lakh in 11.4 years.

3. The Rule of 144 – Quadruple Your Investment

If your goal is to quadruple your investment, the Rule of 144 comes into play. This rule helps you understand how long it will take for your money to grow four times its value at a given rate of return.

Formula:

144 ÷ Rate of Return = Time (in years) to quadruple your money

Example:

With a return of 12% annually,
144 ÷ 12 = 12 years

So, your ₹1 lakh investment will become ₹4 lakh in 12 years.

Reverse Calculation: Estimate Required Return

These rules can also be used in reverse. If you have a time goal, you can determine what rate of return you need.

Example:

You want to quadruple your money in 10 years.

Use the Rule of 144: 144 ÷ 10 = 14.4%

So, you’ll need an investment offering at least 14.4% annual return to reach your goal in 10 years.

Key Tips for Smart Investing

Know your risk appetite: High returns usually come with higher risks.
Diversify your portfolio: Don’t put all your money into one asset class.
Avoid herd mentality: Never invest based solely on others’ opinions or tips.
Start early: The earlier you begin, the more time compounding has to work in your favor.
Stay informed: Regularly review your investments and adjust based on life goals.
