How to Calculate Your Return on Investment

Return on Investment (ROI) measures the gain or loss generated on an investment relative to the amount invested. It is one of the most widely used profitability ratios in finance and investing.

Simple ROI = (Final Value − Initial Investment) / Initial Investment × 100

For investments held longer or shorter than exactly one year, the annualized ROI (or Compound Annual Growth Rate — CAGR) provides a fairer comparison by showing the average annual return.

Annualized ROI (CAGR) = ((Final Value / Initial Investment)^1/years − 1) × 100
