About This Tool
Total Addressable Market (TAM) is the total revenue opportunity available if you captured 100% of your target market. For B2B sales teams, understanding TAM helps prioritize which segments to pursue, how much to invest in outbound, and whether a market is large enough to justify a dedicated go-to-market motion. This free calculator estimates your TAM, SAM (Serviceable Addressable Market — the portion you can realistically serve), and SOM (Serviceable Obtainable Market — what you can capture in year one). It also shows how many decision-maker contacts exist in your target segment and how many are reachable with verified contact data through Cleanlist's 15+ provider waterfall.

What is TAM, SAM, and SOM?
+
TAM (Total Addressable Market) is the total revenue opportunity if you had 100% market share. SAM (Serviceable Addressable Market) is the portion of TAM you can realistically serve with your current product and go-to-market — typically 40-60% of TAM. SOM (Serviceable Obtainable Market) is what you can realistically capture in year one, usually 5-10% of SAM. Investors and sales leaders use these metrics to assess market opportunity and set realistic revenue targets.
