Addressable Market
Addressable market is the portion of a total market that you can realistically reach and sell to. It's not every potential customer in the world — it's the ones your product can actually serve, in the places you can actually operate.
Addressable market refers to the portion of the total market that a company can realistically reach and convert with its current or planned product, distribution capabilities, and business model. It is synonymous with SAM (Serviceable Addressable Market) in most usage.
Addressable market calculation approach:- Start with the total potential buyer population for the problem you solve - Filter by geography (where you operate or can sell) - Filter by segment constraints (company size, industry, tech requirements your product supports) - Filter by accessibility (channels you can reach, languages supported, regulatory access) - Multiply by average annual revenue per addressable customer
Common addressable market errors:- : Defining addressable market as "companies like our current customers" — this under-estimates the real opportunity - : Including buyers you don't have distribution access to reach - : Including buyers whose willingness to pay is below your minimum price point
Temporal dimension:Addressable market expands over time as you add geographies, languages, integrations, and product capabilities. Current vs. future addressable market should be distinguished in strategic planning.
Key Takeaways
- Addressable market is a subset of total market — constrained by product fit, geography, and distribution access
- Addressable market expands as you add geographies, integrations, and product capabilities
- Investors care more about the believability of your addressable market than the size of your TAM
- Always specify the time horizon — current addressable market is smaller than 3-year addressable market
Common Questions
What's the difference between TAM and addressable market?
TAM is the theoretical maximum — all possible buyers globally. Addressable market (SAM) is the subset you can realistically reach with your product and business model. SAM is what actually drives go-to-market decisions.
How do I calculate addressable market for a new product category?
Model the buyer population who have the problem you solve and could benefit from your approach. Estimate willingness to pay through price sensitivity surveys or comparison to alternatives. Constrain by geography and current distribution capabilities.
