Calculate your total addressable market using bottom-up or top-down methods
Pick bottom-up (customer count x revenue) for granular, investor-ready accuracy, or top-down (industry revenue narrowed by segment) for a macro view. We recommend running both.
Input your target customer count, average annual revenue per customer, serviceable percentage, and realistic year-3 market share. Not sure? Try a pre-built example first.
Instantly see all three market tiers. Click Export CSV to download results for your pitch deck, business plan, or strategy presentation.
Both bottom-up (customer-level) and top-down (industry-level) approaches. Run both and compare for the most defensible market size estimate investors trust.
Export TAM, SAM, and SOM results as CSV instantly. Drop the data straight into investor presentations, business plans, or strategy documents.
