Dividend Rule of 72
Use the Dividend Rule of 72 to estimate how long it takes for your dividend income to double based on the growth rate.
📝 Definition
**Dividend Rule of 72** is a simplified mathematical formula used to estimate the number of years required to double your dividend income based on the power of compounding. The formula is `72 / Annual Dividend Growth Rate (DGR)`. This tool helps investors: 1. Visualize the long-term impact of dividend growth. 2. Compare stocks with different growth rates. 3. Plan for future retirement income targets.
In Simple Terms
Imagine an apple tree where the number of apples it produces grows by 12% every year. How long until you get twice as many apples? Just divide 72 by 12, and you get 6 years. The **Dividend Rule of 72** applies this same logic to your stocks. Even if your starting dividend is small, a high growth rate means your 'dividend paycheck' will double in size much faster than you might expect.
Example
If Stock A has a current yield of 3% and increases its dividend by 8% annually, the **Dividend Rule of 72** (`72 / 8 = 9`) tells us the dividend will double in 9 years. This means your Yield on Cost (YoC) would become 6%. If the growth rate were 12%, it would take only 6 years to double.
💡 Practical Tips
- 1Use this rule to evaluate low-yield, high-growth stocks that might look unattractive at first glance.
- 2Ensure the dividend growth rate is higher than inflation to maintain your purchasing power.
- 3If you use a Dividend Reinvestment Plan (DRIP), the time to double your income will be even shorter than the rule suggests.
⚠️ Common Mistakes
This rule assumes the dividend growth rate remains constant. If a company's performance declines and they lower their growth rate, it will take much longer to double your income.
