Calculate ROI
Return on investment is a quick way to compare projects, purchases, campaigns or asset performance. Enter the initial investment, final value and any extra costs to see net return, ROI percentage and return multiple. It is a lightweight planning tool for simple scenarios where you need a fast percentage, not a full finance model.
Simple ROI formula
The calculator subtracts investment and extra costs from final value, then divides the net return by the total invested amount.
