Market Sizing Analysis FAQs

Question 1

What is the difference between TAM, SAM, and SOM?

Accepted Answer

TAM (Total Addressable Market) is the total revenue opportunity with 100% market share. SAM (Serviceable Available Market) is the portion you can actually reach with your current product and geography. SOM (Serviceable Obtainable Market) is the realistic market share you expect to capture within 3-5 years.

Question 2

When should I use Value Theory for market sizing?

Accepted Answer

Value Theory is best for disruptive innovations or new market categories where established research doesn't exist. It calculates market size based on the economic value created and the customer's willingness to pay to solve a specific problem.

Question 3

Which market sizing methodology is most credible for investors?

Accepted Answer

Investors generally prefer the Bottom-Up methodology because it builds the market size from granular customer data and specific pricing assumptions, making it more defensible than broad industry reports used in Top-Down analysis.

Question 4

How do I validate my market sizing calculations?

Accepted Answer

The skill recommends 'triangulation,' which involves comparing results from at least two different methodologies. If your top-down and bottom-up numbers are within 30% of each other, your model is likely well-calibrated.
