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.
