Complete Definition
Compound Annual Growth Rate (CAGR) measures the mean annual growth rate of an investment or metric over a specified time period. It smooths out volatility to show the steady rate at which something would have grown if it grew at the same rate each year.
How to Calculate CAGR
CAGR = (Ending Value / Beginning Value)^(1/Number of Years) - 1
Why CAGR Is Used
- Smooths out yearly volatility - Enables fair comparisons - Shows long-term trends - Standard metric in finance - Easy to understand growth rate
CAGR Applications
Market Growth
"The SaaS market has a 12% CAGR through 2027"
Company Growth
"Revenue CAGR of 50% over 3 years"
Investment Returns
"Portfolio CAGR of 8% since inception"
CAGR Limitations
- Doesn't show volatility or risk - Assumes consistent growth - Can be misleading for short periods - Sensitive to start/end point selection
Interpreting CAGR
- **< 5%**: Low/slow growth - **5-10%**: Moderate growth - **10-25%**: Strong growth - **25-50%**: Very high growth (typical for successful startups) - **> 50%**: Exceptional (early-stage or hypergrowth)
