Market Sizing Template
Turn scattered research into a structured market estimate, so your team makes go or no-go decisions with real numbers behind them.
Entrepreneurs and strategy teams that size markets through scattered research often reach different conclusions depending on who runs the numbers. That makes estimates hard to defend or align around. Typeform's market sizing template gives teams a consistent framework to work through every variable and land on a defensible estimate.
The form captures market definition, target customer segment, addressable population, pricing assumptions, purchase frequency, and penetration rate estimates. Typeform walks respondents through one variable at a time, so nothing gets skipped and the logic stays clear. Conditional logic adapts questions based on the sizing approach selected. A team running a top-down analysis sees different follow-up questions than one working from the bottom up.
Customize the form with your market categories, sizing methodology, and any internal benchmarks your team uses as inputs. Share it via a direct link, embed it in a strategy doc, or send it ahead of a planning session. Every response flows automatically into Google Sheets via Zapier, so inputs are ready to drop into your model. Your team arrives at every pitch, planning session, or board meeting with a market estimate they can actually stand behind.
A market sizing template guides teams through the variables needed to estimate the revenue potential of a specific market. It captures market definition, target segment, addressable population, pricing assumptions, and penetration rate in a single flow. Think of it as a repeatable starting point for any market entry decision.
Ad hoc market sizing produces estimates that are hard to compare, challenge, or build on. A structured template ensures every analysis starts from the same framework, so inputs are consistent and conclusions hold up under scrutiny. It also creates a record of the assumptions behind each estimate, which matters when revisiting a market later. Use it for new product launches, market entry decisions, investor presentations, and strategic planning sessions.
A complete market sizing template covers:
- Market definition and geographic scope
- Target customer segment and profile
- Total addressable market (TAM) estimate
- Serviceable addressable market (SAM)
- Serviceable obtainable market (SOM) and penetration rate assumptions
- Pricing and revenue model inputs
- Key assumptions and data sources
Set up conditional logic to branch the form by methodology, so each team only answers questions relevant to their approach. A team running a top-down analysis sees questions about total industry size, market share assumptions, and macro data sources. One working bottom-up sees questions about unit economics, customer acquisition, and sales capacity instead. This keeps the form focused without forcing every team through the same question set regardless of how they work.
Connect the form to Google Sheets via Zapier so every response populates your model automatically. Map each form field to a variable in your TAM, SAM, or SOM formula so new responses slot straight in. From there, your team runs scenarios, tests assumptions, and shares a live model without starting from scratch each time.
