Understand your ROAS Calculator result
Return on ad spend measures attributed revenue for every euro spent on advertising. It is a revenue efficiency metric and is not the same as profit or ROI.
Worked example
€24,000 in attributed revenue from €6,000 of ad spend produces a 4.00x ROAS: €4 in revenue for every €1 spent on ads.
How to interpret it
The break-even ROAS depends on contribution margin. A 4x result may be strong for one company and unprofitable for another after product, payment and fulfilment costs.
Practical next steps
- Confirm the attribution window used.
- Compare ROAS with contribution margin, not revenue alone.
- Evaluate new and returning customers separately.
Questions to ask before deciding
Are all relevant costs included? Is the time period consistent? How would the result change if volume, price or cost moved by 10%? Save your assumptions so you can compare the estimate with actual performance later.
