What Is CAGR?
Compound Annual Growth Rate (CAGR) is the rate of return that would be required for an investment or metric to grow from its beginning value to its ending value, assuming the growth was compounded annually. It smooths out year-to-year volatility to give you a single annual growth rate that represents the overall trend.
CAGR is used by investors to compare investment performance, by businesses to measure revenue and earnings growth, and by analysts to evaluate company performance. Unlike simple average growth, CAGR accounts for compounding and provides a more accurate measure of consistent growth.
If revenue grew 50% in year 1 and then shrank 33% in year 2, the average growth rate is 8.5%. But the CAGR is 0% (you are back where you started). CAGR accurately reflects the actual outcome; simple averages can be misleading.
CAGR Formula
- 1CAGR = ($22,000 / $10,000) ^ (1/5) - 1
- 2CAGR = (2.2) ^ (0.2) - 1
- 3CAGR = 1.1708 - 1 = 17.08%
- 4Total Growth = ($22,000 - $10,000) / $10,000 = 120%
- 5Doubling Time = 72 / 17.08 = 4.2 years
- 6Projected value in 10 more years = $22,000 × (1.1708)^10 = $108,600
CAGR Applications
| Metric | Typical Healthy CAGR | Great CAGR | Example |
|---|---|---|---|
| S&P 500 Returns | 8-10% | 12%+ | Long-term market performance |
| Revenue Growth | 10-20% | 25%+ | Business sales growth |
| Earnings Per Share | 7-12% | 15%+ | Company profitability growth |
| Dividend Growth | 5-8% | 10%+ | Dividend aristocrats |
| GDP Growth | 2-3% | 4%+ | National economic growth |
| Population Growth | 0.5-1% | 1.5%+ | Demographic trends |
How to Use CAGR Effectively
- CAGR smooths volatility but does not eliminate risk
- The Rule of 72 works best for rates between 5% and 20%
- CAGR is the geometric mean of annual growth rates
- Higher CAGR over longer periods indicates more reliable growth
- Compare CAGR with standard deviation for risk-adjusted analysis
An investment that grows steadily at 17% per year and one that swings between +50% and -10% can have the same CAGR. But the volatile investment carries much more risk. Always look at CAGR alongside volatility metrics for a complete picture.
Using CAGR for Business Performance Benchmarking
In business analysis and corporate reporting, CAGR (Compound Annual Growth Rate) is the standard for measuring revenue growth, earnings growth, and user/customer acquisition over multi-year periods. Investors, analysts, and management teams compare company CAGRs to industry peers to assess relative performance. A software company with 25% revenue CAGR over 5 years is growing meaningfully faster than the typical industry average of 10-15%, suggesting strong market share gains or favorable market dynamics. Conversely, a retailer with -3% revenue CAGR is losing ground, even if a single year showed positive growth due to temporary factors like a competitor closing.
CAGR is also widely used in M&A analysis to justify acquisition premiums. When a company pays 5-10x revenue for a target, the implicit assumption is that the target will sustain a high CAGR for 5-7+ years. Due diligence on CAGR requires understanding the drivers: organic growth (new customers, higher prices, more products per customer) vs. inorganic growth (acquisitions). Organic CAGR is more valuable and sustainable; acquired CAGR resets growth expectations every time a deal closes. Adjusting historical revenue for acquisitions and divestitures to calculate 'organic CAGR' is a standard step in investment banking analysis.
CAGR Forecasting: Market Sizing and Business Planning
Market research firms and management consultants use CAGR projections to size addressable markets and justify strategic investments. A Total Addressable Market (TAM) projected to grow at 15% CAGR from $50B to $100B over 5 years provides a framework for evaluating competitive positioning and investment requirements. Business plans typically present 3-5 year revenue projections as CAGR rather than individual year growth rates to smooth out year-to-year volatility. Investors evaluate whether a company's projected CAGR is plausible given market growth, competitive position, and management execution history. Overly optimistic CAGRs in business plans (hockey-stick projections) are a common red flag that sophisticated investors scrutinize carefully.
Two investments with identical CAGR can have very different risk profiles. Investment A grows steadily at 10% each year. Investment B gains 50% in year 1, loses 30% in year 2, gains 30% in year 3, and so on, producing the same 10% CAGR but with extreme volatility. The Sharpe ratio (excess return per unit of volatility) captures this difference better than CAGR alone. Always pair CAGR analysis with standard deviation or maximum drawdown metrics to understand the risk-adjusted quality of returns.
