Frequently Asked Questions
Compound Annual Growth Rate (CAGR) measures the mean annual growth rate of an investment over a specified period of time longer than one year. It assumes that profits are reinvested at the end of each year. The formula is: (Final Value / Initial Value)^(1/Years) - 1. CAGR smooths out the volatility of periodic returns and is a standardized measure for comparing investment performance over different time periods.
CAGR accounts for compound interest effects and reflects geometric mean growth. A simple average growth rate is arithmetic mean - for example, +50% in year one and -50% in year two would give an arithmetic average of 0%, but the actual CAGR would be -13.4%. CAGR more accurately reflects the annualized return on investment and is better suited for comparing investments with different time horizons.
General benchmarks: CAGR 5-8% indicates conservative investments (bonds, wealth management), 8-15% indicates growth-oriented investments (index funds, quality stocks), and 15%+ indicates high-risk high-reward investments. Long-term, the S&P 500 index averages around 10%, while Warren Buffett's annual return of approximately 20% is considered world-class performance.
