TAM / SAM / SOM Calculator

The TAM / SAM / SOM Calculator sizes your market from the bottom up — starting with a specific customer, price, and purchase frequency — rather than a top-down industry-report number. It produces your Total Addressable Market, Serviceable Addressable Market, and Serviceable Obtainable Market with a plain-language verdict.

Why bottom-up instead of top-down?

Investors have seen thousands of top-down market slides pulled from an industry report. A number built from a specific customer, price, and behavior survives diligence far better.

What SAM and SOM percentages should I use?

SAM (the segment you can realistically serve) is commonly 10–30% of TAM; SOM (what you could capture in 2–3 years) is usually 2–10% of SAM. Adjust based on your actual go-to-market reach.

Is this a substitute for commissioned market research?

No — it is a fast first estimate. For investor-grade sizing, see our Market Research Reports.
