Market Size Calculator

This tool doesn't estimate it for you — TAM (Total Addressable Market) needs to come from industry reports, government data, or your own research into the total revenue opportunity if you captured 100% of the relevant market.

SAM (Serviceable Addressable Market) is the portion of TAM you could realistically serve given your business model, geography, or target segment. SOM (Serviceable Obtainable Market) is the smaller, realistic slice of SAM you could actually capture given competition and your resources.

Because TAM and SAM are useful for showing investors/stakeholders the size of the overall opportunity, but SOM is the closest thing to a believable near-term revenue target — it's what you can realistically plan around.

Only as reliable as your own market research — this tool just does the multiplication. If your SAM% or SOM% estimates are guesses, treat the output as a rough planning figure, not a validated forecast.
