A market analysis is the section of your business plan that proves demand exists. Without it, every revenue figure you project is speculation. Investors know this, which is why the market analysis often determines whether they keep reading or close the document.
Most founders treat market analysis as a formality. They paste in a generic TAM/SAM/SOM triangle, cite an industry report they found on Google, and move on. That approach fails because it answers the wrong question. The question is not "how big is the market" but "why will customers in this market choose you." Every paragraph in your market analysis should build toward that answer.
What a market analysis covers
A market analysis for a business plan typically addresses five areas. Each one builds on the previous, creating a logical chain from broad industry context down to your specific positioning.
Industry overview. Start with the current state of your industry. Size it using revenue figures, not vague descriptors. "The UK meal kit delivery market generated 1.4 billion in revenue in 2025" tells investors something. "The food industry is growing rapidly" tells them nothing. Include growth rate, major trends driving that growth, and any regulatory shifts that affect market entry.
Target market definition. Narrow from the industry to your specific customer segment. Demographics matter, but psychographics matter more. A 35-year-old professional in London is a demographic. A 35-year-old professional in London who orders takeaway four nights a week because they get home at 8pm and have no energy to cook is a target customer. The difference between those two descriptions is the difference between a mediocre market analysis and a good one.
Market size (TAM, SAM, SOM). Total Addressable Market is everyone who could theoretically buy your product. Serviceable Addressable Market is the subset you can actually reach with your distribution model. Serviceable Obtainable Market is what you can realistically capture in year one to three. Investors pay attention to SOM because it reflects your actual business model constraints, not market fantasy.
Competitive landscape. Map your direct and indirect competitors. Direct competitors offer the same product to the same customer. Indirect competitors solve the same problem with a different approach. A meal kit company competes directly with other meal kit companies and indirectly with ready meals, grocery delivery, and restaurants. Missing indirect competitors signals that you have not thought deeply about your market.
Your competitive advantage. After mapping the competition, explain what positions you differently. This must be specific. "Better quality" and "superior customer service" are not competitive advantages because every company claims them. A competitive advantage is something structural: proprietary technology, exclusive supplier relationships, a cost structure competitors cannot replicate, or a distribution channel they have not discovered.
How to research your market without a budget
Founders often assume market research requires expensive databases and consulting firms. It does not. The best market analyses combine free data sources with original primary research that costs nothing but time.
Government data. The Office for National Statistics (ONS) in the UK, the Census Bureau and Bureau of Labor Statistics in the US, and Eurostat for Europe all publish free industry data. These sources carry weight with investors because the methodology is transparent and the data is verifiable.
Industry associations. Most industries have a trade body that publishes annual reports. The British Retail Consortium, the National Restaurant Association, the International Franchise Association. These reports contain market sizing, growth projections, and consumer trend data specific to your sector.
Competitor filings. If your competitors are publicly traded, their annual reports and investor presentations contain market data they paid analysts to compile. Companies House in the UK publishes financial statements for every registered company, including revenue figures that help you estimate market share.
Customer interviews. Talk to 15 to 20 potential customers. Ask them how they currently solve the problem you are addressing, what they spend on it, and what frustrates them about existing solutions. This primary research is more valuable than any industry report because it reveals buying triggers and objections that secondary data cannot capture.
Google Trends and keyword tools. Search volume data shows real demand. If 12,000 people per month search for "meal kit delivery London," that is evidence of market pull that complements your top-down sizing. Trends over time reveal whether demand is growing or plateauing.
Sizing your market with real numbers
The TAM/SAM/SOM framework works when applied rigorously. It fails when founders use it as a vehicle for optimistic guessing. Here is how to build each figure from verifiable data.
Calculate TAM bottom-up. Count the total number of potential customers in your market and multiply by the average annual revenue per customer. If there are 8.2 million households in London and 23% regularly order meal kits at an average of 45 per week, your TAM is 8,200,000 x 0.23 x 45 x 52 = approximately 4.4 billion. That number is defensible because every input can be sourced.
Define SAM by constraints. You cannot serve all of London in year one. If you are launching with next-day delivery from a single kitchen in East London, your delivery radius caps your serviceable market. If that radius covers 1.2 million households with the same 23% penetration, your SAM drops to roughly 645 million. This figure reflects operational reality, not aspiration.
Estimate SOM conservatively. SOM depends on your marketing budget, conversion rates, and operational capacity. If you can produce 500 kits per week in year one and average 45 per kit, your year-one SOM is about 1.17 million. That number does not sound impressive on its own, but it is credible. Investors prefer a founder who says "I will capture 1.2 million in year one" over one who says "we are going after a 4 billion market."
Analyzing your competition effectively
A competitive analysis that lists company names and bullet points of their features is surface-level work. Investors want to see that you understand why competitors succeed, where they fail, and how those gaps create your opportunity.
Build a competitor matrix. List your top five to eight competitors across the columns. Down the rows, track: pricing model, target customer, distribution channels, key features, funding raised, estimated revenue, and notable weaknesses. This matrix becomes the foundation for identifying patterns and gaps.
Study their customers, not their marketing. Read competitor reviews on Trustpilot, G2, Reddit, and app stores. The one-star and three-star reviews reveal pain points that the company has not solved. These pain points are your market entry strategy. If a competitor's customers consistently complain about delivery reliability, and you can solve that problem, you have found a positioning angle backed by evidence.
Map the value chain. Understand how competitors source, produce, distribute, and acquire customers. This reveals cost structures and potential efficiencies. If every competitor uses the same third-party logistics provider and you can build in-house logistics at lower cost, that is a structural advantage worth highlighting.
Identify the white space. After mapping competitors, look for customer segments or needs that nobody is serving well. White space is not always a new product. Sometimes it is a pricing model (subscription vs pay-per-use), a channel (B2B vs B2C), or a geographic market that incumbents have ignored.
Common mistakes in market analysis sections
After reviewing hundreds of business plans, certain patterns of weak market analysis repeat consistently. Avoiding these errors puts your plan ahead of the majority.
Citing only top-down market size. Saying "the global SaaS market is worth 300 billion" does not help your business plan. Investors want to know your slice, calculated from the bottom up. Top-down numbers without bottom-up validation are treated as fiction.
Ignoring indirect competitors. If you claim you have "no competitors," investors hear "I have not done my research." Every business competes with something, even if it is the customer doing nothing. A project management tool competes with spreadsheets, post-it notes, and email threads.
Using outdated data. Citing a 2019 market report in a 2026 business plan signals laziness. Markets shift rapidly, especially post-pandemic. Use the most recent data available and note the publication date for every source.
Describing customers in demographics only. "Women aged 25 to 45" is not a target market. "Working mothers who need dinner on the table by 6:30pm and will pay a premium for convenience" is a target market. The first is a census category. The second is a buying trigger.
Skipping the "so what" connection. Every piece of market data should connect to your strategy. If the industry is growing at 12% annually, explain why that growth rate benefits your specific business model. Raw data without interpretation wastes the reader's time.
Writing a market analysis for different audiences
The depth and emphasis of your market analysis should shift depending on who will read your business plan.
For investors. Lead with market size and growth rate. Investors are evaluating whether the opportunity is large enough to justify their return expectations. A venture capital investor typically needs a 100 million or larger addressable market. An angel investor may be satisfied with smaller, more focused markets. Emphasize defensibility and competitive moats. Show that you understand unit economics within your market segment.
For bank loans. Banks care less about total market size and more about demand stability. They want evidence that customers exist and will continue to exist. Focus on local market conditions, proven demand (pre-orders, waitlists, letters of intent), and competitive positioning that suggests stable revenue. Include data on market maturity, because banks prefer established markets with predictable cash flows.
For internal planning. When the market analysis serves your own strategy rather than an external audience, go deeper on competitive dynamics and customer segments. This version should inform your marketing spend allocation, pricing decisions, and product roadmap. Be honest about weaknesses and threats, because this document is a planning tool, not a sales pitch.
Presenting market data clearly
How you present your market analysis matters as much as the data itself. Dense paragraphs of statistics lose readers. Clean formatting keeps them engaged.
Lead with the headline number. Open each subsection with the most important figure. "Your target market includes 340,000 small businesses in the UK that spend an average of 2,400 per year on accounting software." That single sentence communicates market size, customer profile, and spending behaviour.
Use tables for competitor comparisons. A well-formatted competitor matrix communicates more in a single page than three paragraphs of prose. Highlight the column where your business outperforms on the dimension that matters most to your target customer.
Source everything. Every market figure should have a citation. "Source: ONS Business Population Estimates, 2025" takes five seconds to add and dramatically increases credibility. Unsourced numbers are treated as opinions, not facts.
Visualize growth trends. A simple line chart showing five years of industry growth is more persuasive than a paragraph describing the same trend. Charts belong in your market analysis. They break up text, improve scannability, and make growth patterns immediately obvious.
Build a market analysis that proves demand
The purpose of a market analysis is not to demonstrate that you can search the internet for statistics. It is to prove, with evidence, that real customers exist who will pay real money for what you are building.
Start with the customer. Talk to them. Understand their spending habits, frustrations, and decision-making process. Then layer on industry data, competitive intelligence, and market sizing to build a case that is both rigorous and specific to your business.
