Description

An Excel template for founders, students and consultants who need a market size they can defend.

What is included

  • Top-Down sheet: total customers x revenue per customer gives TAM. Apply your own geography, segment and fit filters to reach SAM, then a realistic share to reach SOM.
  • Bottom-Up sheet: build revenue from sales channels, people reached, conversion and revenue per customer.
  • Summary sheet: TAM, SAM, SOM and bottom-up revenue together, a check that the two methods agree within 2x, and a one-line summary ready to paste into a slide.
  • A Source column next to every input so you can cite where each number came from.

Good to know

  • This template contains no market data. The starting numbers are examples; replace them with figures you can source.
  • Works in Microsoft Excel. No macros.
