Simple Definition

Compound Annual Growth Rate. The average yearly growth rate of an investment over a specific period.

Why It Matters

CAGR smooths out volatile returns into a single annual number, making it easy to compare investments. If your portfolio went from $10,000 to $25,000 over 10 years, the CAGR is about 9.6% - even if some years were up 30% and others down 15%. It's the standard way to compare funds, stocks, and asset classes over time.

Key Points

  • Calculate it: (Ending Value / Beginning Value)^(1/Years) - 1
  • The S&P 500 has a CAGR of roughly 10% since 1926 (before inflation)
  • CAGR ignores volatility - two investments with the same CAGR can have very different risk profiles
