# TAM

Concept · [Business and metrics](https://ecosystem.samcarlton.com/business)

Also called: total addressable market, market size, SAM, SOM, TAM SAM SOM, serviceable market

Total addressable market. All the money that could be spent on a product like yours if every possible customer bought it. SAM and SOM are smaller slices: the part you could actually reach, and the part you could realistically win.

**For example:** For a dog-walking app, TAM is everything dog owners in the country spend on dog walking. SAM is that spending in the cities you serve. SOM is the share of those owners you can realistically sign up.
