What this calculator measures
ROAS reports attributed advertising revenue per unit of ad spend. It does not subtract product cost, agency fees, or overhead.
Formula
ROAS = Revenue from Ads / Ad Spend
Worked example
- 1Ads generate $21,000 from $5,000 spend.
- 2$21,000 / $5,000 = 4.2, shown as 4.2:1 and 4.2x.
How to interpret the result
A sustainable target must reflect gross margin, attribution quality, returns, and operating costs.
Common mistakes and limits
- Mixing attribution windows, counting total revenue instead of attributed revenue, or treating ROAS as profit.
Frequently asked questions
Is 4x ROAS profitable?
Only if the revenue's contribution after other costs exceeds the ad spend.
Can platforms disagree?
Yes. Attribution models and conversion windows differ.
Why is zero spend invalid?
A return per unit of spend cannot be calculated without spend.
