Scenario guidance
When to use this
Use this when comparing how much revenue was attributed to advertising against the spend used to generate it.
Example scenario
A marketer is reviewing a paid campaign and wants a quick ROAS estimate before checking margin and fulfillment costs.
Inputs that usually matter most
- Ad revenue, because it is the revenue attributed to the campaign or channel.
- Ad spend, which is the cost used to generate that attributed revenue.
- Attribution window and tracking method, because they affect which revenue is counted.
Common mistake to avoid
Do not treat ROAS as profit; it does not subtract product cost, labor, platform fees, refunds, or overhead.
How to interpret the result
Use ROAS to compare advertising efficiency, then evaluate margin, CAC, payback, and cash flow before making campaign decisions.
Results are estimates for planning and education. They are not business, tax, legal, or financial advice.
Formula
Return on ad spend divides revenue attributed to ads by ad spend. ROAS percentage multiplies that ratio by 100.
Example ROAS
$25,000 in ad revenue from $5,000 in ad spend is a 5.0 ROAS, or 500% return on ad spend.
Frequently Asked Questions
Is ROAS the same as profit?
No. ROAS compares ad revenue with ad spend, but it does not subtract product costs, labor, fees, refunds, or overhead.
Why is ROAS undefined when ad spend is zero?
ROAS divides by ad spend, so zero ad spend makes the ratio undefined.
