Direct answer: ROAS equals attributed revenue divided by advertising spend. Break-even ROAS in this simplified calculator is approximately one divided by gross-margin rate; real profitability also depends on fulfilment, returns, taxes and operating costs.
How to interpret ROAS
High ROAS is not automatically profit. Margin, fulfilment, returns, taxes and operating costs matter. This calculator uses a simplified gross-margin model; validate with finance data.
ROAS formulas
ROAS = attributed revenue ÷ ad spend. Contribution after ads is estimated as revenue multiplied by gross margin, minus ad spend.
When ROAS misleads
- Revenue is attributed under inconsistent windows.
- Returns or cancellations are ignored.
- New and returning customers are mixed.
- Margin varies materially by product.
- Agency, creative and fulfilment costs are omitted.
Frequently asked questions
What is a good ROAS?
There is no universal target; it depends on margin, operating costs, repeat purchase and business objectives.
How is ROAS calculated?
Divide attributed revenue by advertising spend for the same scope and period.
What is break-even ROAS?
It is the ROAS at which contribution covers advertising cost under stated margin assumptions.
Is ROAS the same as profit?
No. ROAS does not automatically include other costs.
Should tax and returns be included?
Use finance-approved net revenue and cost definitions for decision-grade reporting.
