How to Do Market Analysis for a Business Plan

A strong market analysis shows investors and lenders that you know your customers, competitors, and demand. If you are asking how to do market analysis for a business plan, you are in the right place. In this guide, you will learn how to size your market, study competitors, set smart prices, and build supportable forecasts. According to Optimus Business Plans industry data, our team has produced 2,100+ bank-ready and investor-ready business plans since 2010 across 200+ industries. We have seen what works and what raises red flags.

Your goal is simple: prove there is a real, reachable opportunity and that you can win part of it. Use the steps below to gather facts, turn them into insights, and present them clearly in your plan. Along the way, we will show you how to connect your market findings to pricing, marketing, and cost assumptions that investors expect.

Define your market and customer segments

Start by drawing a clear boundary around your market. State what you sell, to whom, and where. A “market” is not everyone. It is a defined group of buyers with a shared need and a way to reach them. If you serve both consumers and businesses, split them. Use simple terms: age ranges, income levels, locations, industries, job titles, and buying triggers. Keep it practical. If a reader cannot picture your customer after two sentences, you need more detail.

Create segments that you can target with different messages and offers. For example, a fitness studio might split the market into young professionals who want high-intensity classes and parents who prefer flexible schedules. A B2B software firm might segment by company size and industry. Good segments are measurable, reachable, and profitable. Avoid segments that are too broad or too small to matter.

• Define your primary use case (what problem you solve)
• Choose your geography (local, regional, national)
• Specify buyer types (B2C demographics or B2B firmographics)
• Note pain points and buying triggers for each segment
• List how you will reach each segment (channels, partners, or platforms)

Size the opportunity: TAM, SAM, and SOM

Investors expect to see the size of the prize. Use three simple terms:

• Total Addressable Market (TAM): all possible demand for your category
• Serviceable Available Market (SAM): the part of the TAM you can serve with your model and location
• Serviceable Obtainable Market (SOM): the realistic share you can win in the next few years

Use a bottom-up method when you can. Start with the number of target buyers in your SAM and a realistic annual spend per buyer. Multiply those two figures to estimate revenue potential. You can find buyer counts from sources like the U.S. Census, industry directories, or local economic reports. For B2B, use databases and trade associations to count target firms and locations. Cross-check your math with a top-down view from industry reports to see if your estimate seems reasonable.

Explain your assumptions in plain words. If you focus on a single metro area, show why this location fits your offer. If your buyers are hospitals, define the number of hospitals that match your criteria. Keep your SOM grounded by tying it to your planned sales capacity and marketing reach. A thoughtful, modest SOM builds more trust than a bold guess.

• Use bottom-up math (buyers × spend) for SAM
• Cross-check with top-down industry data
• Tie SOM to sales capacity and channel reach
• Show geography, constraints, and ramp timing

Analyze demand drivers and trends

A market does not grow or shrink at random. Explain the forces that drive demand. These include customer behavior, technology, regulation, seasonality, and local economics. Describe how these factors help or hinder your offer. If your product rides a clear trend, explain why that trend is durable. If there are headwinds, show how you will adapt. Investors respect a balanced view that weighs upside and risk.

Use simple tools to validate trends. Scan Google Trends for keyword interest. Read recent trade journals to note shifts in buyer priorities. Review competitor press releases and product updates to spot positioning changes. For local services, talk to nearby business owners and customers about foot traffic, buying habits, and price sensitivity. Convert your notes into two lists: what boosts demand and what could slow it down.

• Demand boosters: new tech, easier adoption, behavior shifts
• Demand blockers: regulation, switching costs, low awareness
• Seasonal effects: holidays, weather, school calendars
• Cycles: budget renewals in B2B, housing moves in B2C

Map the competitive landscape

Every buyer has options. Show that you know who else serves your customer and how you stand apart. Divide competitors into direct (sell a similar product to the same buyer) and indirect (solve the same problem in a different way). Visit their sites and stores. Note prices, features, service levels, guarantees, locations, and marketing claims. Summarize this in a short narrative that highlights the gaps you will fill.

Then, compare your positioning. What will you do better or differently? This could be speed, convenience, deeper expertise, or a unique bundle. Avoid vague claims like “better quality.” Be specific, such as “same-day delivery within the city” or “24/7 live support.” Show how your channels, partnerships, or IP help you defend your position. If competitors are strong, acknowledge it and point to underserved segments or pain points.

• Build a quick competitor matrix (features, price band, channel)
• Identify switching costs and how you reduce them
• List your top three differentiators customers will notice
• Explain how you will respond to likely competitor moves

Pricing, revenue, and cost assumptions that fit the market

Your market analysis should lead to a clear pricing approach. Describe the value drivers your customers care about and the price bands they see today. Explain the model you will use: one-time sale, subscription, tiered plans, usage-based, or bundles. Tie price to the benefits you deliver and to the alternatives customers compare. Show how promotions or discounts fit the launch stage without training customers to expect permanent deals.

Ground your cost assumptions with benchmarks. According to Optimus Business Plans industry data, typical small-business operating-expense ratios often allocate about 35% of revenue to salaries, 8% to rent, 2% to utilities, 12% to marketing, 3% to insurance, 5% to supplies, 4% to professional services, and 3% to other costs. Use these as a starting point and adjust for your model. A software firm may spend more on salaries and less on rent. A restaurant may spend more on supplies and utilities. Explain your variances so readers see you are not guessing.

• Link price to clear benefits and competitor anchors
• Choose a simple, testable model for launch
• Use expense ratios to sanity-check your forecast
• Note which costs scale with revenue and which are fixed

Validate with real customers before you forecast

Paper research is not enough. Test your assumptions with real people. Start with quick customer interviews. Ask about problem urgency, current solutions, and willingness to pay. Follow with short surveys to rank features and price ranges. For B2C, run small ad tests to measure click and sign-up interest on a simple landing page. For services, try a pilot or pre-orders to see who commits first. Keep a log of what you learned and what you changed.

Share how validation shaped your plan. Did interviews reveal a must-have feature or a deal-breaker? Did a test campaign show that one segment responds better than another? Use these insights to refine your SAM and SOM, your pricing tiers, and your launch channel mix. Investors want to see a cycle of learn-test-learn, not a fixed idea that never adapts.

• 10–15 interviews per segment can reveal patterns quickly
• Pilot offers, pre-sales, or waitlists to measure intent
• Track feedback themes and connect them to plan changes
• Cut low-interest features and double down on winners

Turn your findings into a clear market section

Now package your work for the plan. Keep it structured, visual, and brief enough to scan. Start with a short summary of the opportunity and your core customer. Follow with TAM/SAM/SOM, buyer personas, demand drivers, and competitor positioning. Close with pricing logic and the key assumptions that feed your forecast. Use charts or simple visuals where helpful, and place details in the appendix.
