ROAS Calculator

The ROAS Calculator computes true return on ad spend across any channel — Google, Meta, TikTok, or blended — accounting for contribution margin, not just topline revenue. Most brands misread their ROAS because they treat revenue as profit. This tool fixes that.

What this means

Healthy margins. You have room to scale — paid media spend can likely increase 30-50% while maintaining profitability, assuming CAC doesn't degrade significantly.

About the ROAS Calculator

ROAS is the most cited and most misunderstood metric in paid media. A 4x ROAS on a 20% margin product means you are barely breaking even. A 2x ROAS on a 60% margin product is genuinely profitable. The difference gets missed in quarterly reviews, and millions of ad dollars get misallocated as a result. Our calculator takes four inputs — revenue, spend, COGS, and other variable costs — and returns both blended ROAS and contribution-margin-adjusted ROAS so you can make allocation decisions with real numbers.

Yes — 100% free, no signup, no email wall. We built it because our operators needed it and decided to share.

No. All calculations run entirely in your browser. Nothing is sent to or stored on any server.

Reach out — we will share an embed snippet for teams that want to use this inside their own workflows.

Yes. No signup required, no data collected, nothing sent to our servers. Everything runs in your browser. We publish free tools because they build trust with operators who might eventually hire us — that's the entire business model.

The math is correct and the formulas are standard. The output is only as good as the inputs you provide — garbage in, garbage out applies here like anywhere. We recommend calibrating with at least 3 months of real data before making major decisions based on the results.

The tool lives at a stable URL that you can share with your team. We don't currently offer embeds, but the output is shareable via the copy button on calculator results. For white-label or embedded versions, contact us directly.

Three reasons. First, they help operators make better decisions even if they never hire us. Second, they let us show our thinking publicly — the frameworks behind these tools come straight from our client engagements. Third, they attract the kind of operators who later become great clients.

The free tools cover standard scenarios. For custom analysis — multi-channel attribution, cohort LTV modeling, MMM — we do this as part of paid engagements. Our CRO & Analytics service starts at $6k/month and includes custom dashboarding plus BigQuery setup if needed.
