CAGR (Compound Annual Growth Rate)
The annualized rate of return that, if applied consistently each year, would produce the same total return over the investment period. For example, a strategy that turns $100 into $250 over 5 years has a CAGR of approximately 20.1%. CAGR is the most honest single number for comparing strategies across different time horizons. For reference, the S&P 500 has delivered approximately 10% CAGR over the long term, while a traditional 60/40 portfolio has delivered roughly 7–8%. Its limitation is that it conceals volatility entirely—two strategies with identical CAGR can have wildly different risk profiles.
