How it is calculated
ROI = (revenue − ad spend) ÷ ad spend × 100%. This is the standard ROI formula applied to an ad campaign: it shows by what percentage revenue exceeded the budget spent on advertising.
The formula equals (ROAS − 1) × 100%, since ROAS = revenue ÷ spend: if you've already computed ROAS, ad campaign ROI can be derived from it directly, with no need to recompute from scratch.
This is revenue-based ROI, not profit-based — it doesn't account for the cost of goods sold. For a profit-based figure on ad performance, use the separate ROMI calculator, which subtracts not just ad spend but margin costs from revenue too.
