TAM (Total Addressable Market)
Total Addressable Market (TAM) is the total revenue opportunity available for a product or service if it captured 100% of the relevant market — used in strategic planning, fundraising, and territory design.
What is TAM (Total Addressable Market)?
TAM is the largest market figure in a typical analysis, sized as the full revenue available across all potential customers. Two related figures: SAM (Serviceable Addressable Market) is the portion of TAM your product can actually serve given current scope; SOM (Serviceable Obtainable Market) is the portion of SAM you can realistically capture in the planning horizon. TAM is most useful when sized bottom-up (count of qualifying accounts × average contract value) rather than top-down (industry analyst report × growth rate). Bottom-up TAM is auditable; top-down TAM is mostly storytelling.
Why it matters
- Foundation of strategic planning, fundraising, and territory design.
- Bottom-up sizing is auditable; top-down sizing is mostly storytelling.
- TAM, SAM, and SOM each serve a different planning purpose.
Use cases
- Fundraising narrative. TAM sizing as a key component of investor story.
- Territory design. TAM by geography or segment informs how to carve sales territories.
- Strategic planning. TAM by product or vertical informs portfolio decisions.
