About This Calculator

Return on investment (ROI) measures the profitability of any investment as a percentage of the original cost. This calculator handles investments with income (dividends, rent, interest) plus capital appreciation, and shows both total ROI and the annualized CAGR for fair comparison across different time periods.

Estimates only — not financial, tax, legal, or investment advice. Verify important results with a qualified professional before making decisions.

ROI = (final value + income − cost) / cost × 100; annualized ROI = (final/cost)^(1/years) − 1; net gain / loss = final value + income − cost
