CAGR (연평균 성장률)
Key dividend investing concept. CAGR (연평균 성장률) is an essential metric for understanding dividend portfolio performance and making informed investment decisions.
📝 Definition
Definition of CAGR
CAGR (Compound Annual Growth Rate) is the mean annual growth rate of an investment over a specified period of time longer than one year. It represents the geometric progression ratio that provides a constant rate of return over the time period, smoothing out the year-to-year volatility. Essentially, it tells you what your investment grew at each year as if it had grown at a steady rate on a compounded basis.
Formula: [(Ending Value / Beginning Value)^(1 / Number of Years)] - 1
Unlike a simple average, CAGR accounts for the fact that gains and losses are compounded. It is the most accurate way to determine returns for anything that can rise or fall in value over time.
In Simple Terms
Importance in Dividend Investing
For dividend investors, CAGR is the speedometer of your snowball. What matters most isn't just today's yield, but the Dividend CAGR (Dividend Growth Rate) over the last 3, 5, or 10 years. A dividend CAGR of 10% means your passive income is growing by 10% compounded every year, which is the key to beating inflation and achieving financial independence faster.
It also serves as a measure of reliability. By looking at the long-term CAGR, you can filter out one-time special dividends and identify companies that have a disciplined, decade-long commitment to increasing shareholder payouts.

Practical Usage & Checklist
How to use CAGR to build a winning portfolio:
- Check the 5-Year Dividend CAGR: Aim for companies with a 5-year CAGR of at least 7-10%. These are considered high-quality dividend growers.
- Compare with EPS CAGR: Ensure that Earnings Per Share (EPS) CAGR is equal to or higher than the Dividend CAGR. If dividends grow faster than earnings, the payout ratio will eventually become unsustainable.
- Apply the Rule of 72: Use the CAGR to estimate when your income will double. For example, a 12% CAGR means your dividend check will double every 6 years (72 / 12 = 6).
💡 Practical Tips

- 2Compare CAGR (연평균 성장률) across similar companies in the same sector.
- 3Monitor changes in CAGR (연평균 성장률) over time for trend analysis.
⚠️ Common Mistakes
Traps & Limitations
CAGR is a useful summary, but don't ignore its weaknesses:
- Ignores Volatility: CAGR hides the "bumps" in the road. It won't tell you if the stock dropped 50% in year two before recovering. It doesn't reflect the emotional stress of the journey.
- Sensitivity to Endpoints: If your end date happens to be during a market crash, your CAGR will look terrible regardless of long-term performance. Always look at multiple time horizons (3Y, 5Y, 10Y).
- Past is Not Prologue: A high historical CAGR does not guarantee future results. As companies mature, their growth rates naturally decelerate.
