CAGR — Compound Annual Growth Rate
Annualized geometric return from a starting value, ending value, and time. Optionally adjust for inflation and compare nominal vs real growth. Exact doubling time and Rule-of-72 are shown for quick intuition.
Compound Annual Growth Rate
Tip: decimals work (e.g., 1.75 years).
Used to compute a “real” (inflation-adjusted) CAGR.
Formulae: CAGR = (End / Begin)1/Years − 1; real CAGR (Fisher-style) ≈ (1+nominal)/(1+inflation) − 1; doubling time (exact) = ln(2)/ln(1+CAGR); Rule-of-72 is an approximation.
UX approach: clear inputs, instant feedback, quick presets, and progressive disclosure for advanced options.
