Marketing ROI Calculator
Calculate marketing ROI as a percentage return on spend, with a clear distinction from ROAS and from accounting profit.
This ROI nets your marketing cost out of the revenue it generated and expresses the result as a percentage return — a 200% ROI means you got back 3x your spend total (your original spend plus 200% more). ROAS, by contrast, is a plain ratio of revenue to spend (e.g. "4x") with no subtraction. Neither of these is the same as accounting profit — this calculation only accounts for marketing cost, not cost of goods sold, overhead, or any other expense.

Calculate marketing ROI as a percentage return on your marketing spend — (Revenue − Marketing Cost) ÷ Marketing Cost × 100. A negative result means the campaign lost money relative to its own cost.
This is a different metric from ROAS, which is a plain revenue-to-spend ratio with no subtraction — and neither one is the same as accounting profit, since this calculation only nets out marketing cost, not cost of goods sold or other overhead.
