Total Addressable Market (TAM)
The total market demand for a product or service — the maximum revenue opportunity available if 100% market share were achieved.
Total Addressable Market (TAM) is the total revenue opportunity available for a product or service if it achieved 100% market penetration. Calculation methods: top-down (use industry reports and analyst data to estimate the total market size), bottom-up (count potential customers × average contract value × purchase frequency), and value-theory (estimate the value created for customers and price accordingly). SAM (Serviceable Addressable Market) is the portion of TAM your product can realistically serve given current capabilities and go-to-market reach. SOM (Serviceable Obtainable Market) is the realistic share you can capture near-term. For B2B marketing strategy, TAM/SAM/SOM analysis guides: where to focus sales and marketing resources, which segments offer the highest density of ideal customers, and how to prioritize geographic markets. For fund managers, TAM analysis identifies the addressable capital pool — total assets managed by target LP types that could realistically allocate to the fund's strategy.
