How well did your investment perform? Our ROI calculator shows total return percentage, annualized ROI (CAGR), and absolute gains. Compare investments of different sizes and time periods to see which performed better.
Understanding ROI and CAGR
ROI (Return on Investment) shows total percentage gain or loss. CAGR (Compound Annual Growth Rate) annualizes the return for fair comparison across different time periods. An investment that doubles in 10 years has 100% ROI but only 7.2% CAGR.
