CAGR — The True Yardstick of Investment Performance
Compound Annual Growth Rate (CAGR) smoothes the volatile annual returns of an asset into the single rate that, if compounded yearly, would have produced the observed end value. It is the only fair way to compare two investments of different durations.
Formula
CAGR = (FV / PV)^(1/n) − 1
Caveats
- CAGR hides volatility — a 12% CAGR can come from a smooth ride or a 50% drawdown followed by recovery.
- For lumpy cash-flows, use XIRR instead.
- Compare against an appropriate benchmark (Nifty TRI, debt index) — raw CAGR alone is meaningless.
