ROI formulas
ROI = (Final Value + Income − Cost) / Cost × 100%
CAGR = (Final Value / Cost)^(1/years) − 1
Rule of 72: Years to double ≈ 72 / Annual ROI%
CAGR = (Final Value / Cost)^(1/years) − 1
Rule of 72: Years to double ≈ 72 / Annual ROI%
CAGR (Compound Annual Growth Rate) accounts for compounding and is more meaningful than simple ROI for investments held longer than a year.
