Everything you need to know about calculating TAM with real company data

Total Addressable Market (TAM) is the total revenue opportunity for a product or service. It represents the maximum amount of revenue a business can generate by selling its product or service in a specific market, assuming 100% market share.

TAM is calculated by multiplying the total number of potential customers by your Average Contract Value (ACV). Our calculator uses Hunter's B2B database to identify companies matching your criteria, then multiplies that count by your ACV to estimate your total addressable market.
