What this result means

Calculate return on investment (ROI) from initial cost, ending value, and optional net cash flows. ROI % = ((Ending value + Net cash flows − Initial investment) ÷ Initial investment) × 100.

  • Optional fields use sensible defaults when left blank.

ROI

ROI % = ((Ending value + Net cash flows − Initial investment) ÷ Initial investment) × 100.

Example

$10,000 grows to $14,500 with no interim flows → 45% ROI and $4,500 gain.
