How to Write a Market Analysis for a Business Plan
A comprehensive market analysis proves there's demand for your product and shows investors you understand your competitive landscape.
Your market analysis is arguably the most research-intensive section of your business plan. It answers critical questions: How big is your market? Who are your customers? Who are you competing against? And most importantly—is there room for your business to succeed?
Investors scrutinize this section carefully because it demonstrates whether you've done your homework and understand the market dynamics that will make or break your business.
Understanding Market Size: TAM, SAM, and SOM
The most credible way to present market size is using the TAM-SAM-SOM framework:
TAM (Total Addressable Market)
The entire revenue opportunity if you captured 100% of the market. This is the broadest view.
Example: Global project management software market = $6.5B annually
SAM (Serviceable Addressable Market)
The portion of TAM your business model can actually serve. This accounts for geographic, product, and business model constraints.
Example: Project management software for remote teams in North America = $890M annually
SOM (Serviceable Obtainable Market)
The realistic portion of SAM you can capture in the near term (3-5 years), considering competition and resources.
Example: Our realistic 3-year market capture = $45M (5% of SAM)
⚠️ Common Mistake
Don't just cite the TAM and assume investors will be impressed. They want to see you've thought critically about what's actually achievable. A realistic SOM with a clear path to capture it is far more convincing than inflated TAM numbers.
Defining Your Target Customer
Create detailed customer personas that go beyond basic demographics. Investors want to see you understand your customers deeply.
B2C Customer Profile
Demographics
Age, gender, income, education, location
Psychographics
Values, interests, lifestyle, behaviors
Pain Points
Problems they're trying to solve
Buying Behavior
How they research and make purchase decisions
B2B Customer Profile
Firmographics
Industry, company size, revenue, location
Decision Makers
Who influences and approves purchases
Business Challenges
Operational pain points your product solves
Buying Process
RFP cycles, budget timing, stakeholders involved
Conducting Competitive Analysis
Identify direct competitors (same product/market) and indirect competitors (different solution to same problem). Analyze each using this framework:
| Competitor | Strengths | Weaknesses | Market Share | Your Advantage |
|---|---|---|---|---|
| Competitor A | Established brand, large user base | Outdated UI, poor mobile experience | 35% | Modern interface |
| Competitor B | Low price point | Limited features, no integrations | 15% | Superior features |
| Competitor C | Enterprise-focused, robust security | Expensive, complex setup | 25% | Easier onboarding |
Pro Tip: The Competitive Matrix
Create a 2x2 matrix positioning competitors based on two key dimensions (e.g., price vs. features, or simplicity vs. power). This visual instantly shows your unique positioning and market gap.
Example: Position competitors on axes of "Price" (low to high) and "Feature Complexity" (simple to advanced). Show where you fit and explain why that space is underserved.
