What is Total Addressable Market (TAM)?
The total revenue opportunity available if you captured 100% of your target market.
Definition
Total Addressable Market (TAM) represents the maximum revenue opportunity for your product or service, assuming 100% market share. SAM (Serviceable Addressable Market) is the portion of TAM you can realistically serve given your product's features and geographic reach. SOM (Serviceable Obtainable Market) is the portion you can capture in the near term. For B2B outbound, understanding TAM helps you prioritise which market segments to target first.
Why Total Addressable Market (TAM) Matters
Knowing your TAM prevents two mistakes: targeting too broadly (wasting resources on unqualified accounts) and targeting too narrowly (missing growth opportunities). For Indian B2B companies, a well-defined TAM informs ICP definition, sales team sizing, and growth projections.
