Understanding ROAS
How we calculate. ROAS = attributed ad revenue ÷ ad spend (often shown as a multiple, e.g. 4.0x). The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical ROAS case uses attributed ad revenue 20000 and ad spend 5000. Enter the same figures below to reproduce the worked path.
What is ROAS?
A core paid-media efficiency metric. ROAS is not the same as profit ROI unless revenue is replaced with profit.
- Match attribution windows for revenue and spend
- 4.0x = 400% return framing—label which style you report
- Platform ROAS can differ from blended analytics ROAS
The Formula
Worked Example
Common Use Cases
- Campaign reviews: kill or scale ads
- Budget planning: target ROAS floors
- Channel compare: Meta vs Google efficiency
Pro Tips
- Use profit ROAS when margins are thin
- Exclude brand halo carefully
- Track incremental lift for true incrementality
Limitations: ROAS results are educational marketing planning aids—not guarantees of campaign performance. Platform definitions and attribution models vary.
FAQ
ROAS vs ROI?
ROAS divides revenue by ad spend. ROI usually uses (profit − cost) ÷ cost and may include non-ad costs.
Is 3x good?
It depends on margin. A 3x ROAS can lose money if contribution margin is low.
