Method
How to calculate ROAS
Return on ad spend divides revenue attributed to advertising by advertising spend. It measures revenue efficiency, not profitability, because it does not deduct product, fulfillment, staffing, or operating costs.
Formula
ROAS ratio = Revenue from ads ÷ Ad spend ROAS percentage = ROAS ratio × 100
Assumptions
- Attributed revenue and ad spend cover the same campaign and attribution period.
- Advertising spend is greater than zero.
- ROAS measures attributed revenue, not gross profit or net profit.
- The attribution method used to assign revenue remains consistent.
The ratio and percentage calculations retain full numeric precision. The ROAS ratio and percentage display two decimals; currency displays two decimals.
How to interpret the result
A 4.00x ROAS means the campaign generated $4.00 in revenue for every $1.00 spent on advertising. Whether that result is profitable depends on product cost, fulfillment, payroll, commissions, transaction fees, overhead, attribution quality, and other expenses.
ROAS measures revenue, not profit
A campaign can have a positive ROAS and still lose money after cost of goods, payment fees, fulfillment, discounts, staffing, and overhead. Compare campaign ROAS with a break-even target based on your own economics.
Use one attribution basis
Keep revenue and spend aligned to the same campaign, date range, currency, and attribution method. Differences between advertising platforms and analytics systems can change the amount of revenue credited to a campaign.
ROAS and ROI compared
The two measures answer different performance questions.
| Measure | Formula | What it shows |
|---|---|---|
| ROAS | Attributed revenue ÷ Ad spend | Revenue returned for each advertising dollar spent. |
| ROAS percentage | ROAS ratio × 100 | The same revenue return expressed as a percentage. |
| ROI | Net return ÷ Investment cost × 100 | Profitability after the costs included in the analysis. |
