Market Sizing (TAM / SAM / SOM)
Calculate total addressable market for your category
TAM — Total Addressable Market
$79.2B
330,000,000 people × $240
SAM — Serviceable Addressable Market
$9.5B
39,600,000 people (target profile)
SOM — Serviceable Obtainable Market
$99.8M
415,800 realistic customers

Investors typically view TAM as a ceiling, SAM as the competitive arena, and SOM as your 3-5 year target. Be skeptical of SOM percentages above 10% in mature categories.

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.
