How To Calculate Total Addressable Market (and make a great TAM slide for investors)

About This Video

A great TAM slide doesn't just show a big number --- it tells a story about market opportunity that makes investors lean in. TK Kader teaches you how to calculate your total addressable market using defensible methodology and then, crucially, how to present it in a way that builds credibility rather than skepticism. This video covers both the math and the narrative: the step-by-step calculation process for bottom-up TAM, the data sources that carry weight with sophisticated investors, and the slide design principles that make your market opportunity instantly understandable. Kader explains why the standard "three circles" TAM slide often backfires and shows you how to build a TAM slide that demonstrates deep market understanding rather than just big numbers. He also covers how to handle the inevitable questions investors will ask --- from "how did you get that number?" to "why isn't the market bigger?" --- so you're never caught off guard in a pitch meeting.
