ROI Formula Explained with Example

ROI, or return on investment, measures how profitable an investment is compared to its original cost.

The formula

ROI = (Profit / Investment) × 100

What each part means

  • Profit = Final Value − Initial Investment
  • Investment = Original amount invested

Example

If you invest $10,000 and your final value becomes $12,000, your profit is $2,000. ROI = ($2,000 / $10,000) × 100 = 20%.
