What Is Market Analysis?
Market analysis is the process of researching and documenting how attractive and competitive a specific market is, so a business can decide whether to enter it, how to position in it, or how much to invest in it. A complete market analysis answers four questions: how big is this market and how fast is it growing, who are the customers and what do they need, who else is competing for them, and what external forces, regulatory, economic or technological, could change that picture.
What this method is.
A precise definition, its boundaries, and when it applies -- before any formula or worked example.
Definition
Market analysis is the structured, evidence-based study of a specific market inside a specific industry: its size, growth trajectory, customer segments, competitive structure, and the economic, regulatory and technological forces acting on it.
It combines quantitative market research (numbers: size, growth rate, spending, share) with qualitative context (why customers buy, how competitors behave, what could change) into a single, decision-ready picture. The output is not raw data; it is a documented, sourced assessment used to decide whether, where, and how to compete in that market.
Scope and exclusions
A market analysis studies one market at a time (for example "cloud-based inventory-management software sold to mid-sized retailers in Brazil", not "software" in general) and typically covers demand, supply, competitors, customer segments, pricing, regulation, and forward-looking scenarios for that market.
It is not the same as: market research (the primary/secondary data-gathering activity that feeds a market analysis, but is narrower and more tactical); a full business plan (which also covers operations, team and financials, of which market analysis is one section); a company valuation (a finance exercise using different methods, e.g. discounted cash flow); or a single statistic (a market-size figure on its own is an input to a market analysis, not the analysis itself).
When to use it
- Before writing a business plan or raising investment, to size the opportunity and show you understand who you are selling to.
- Before entering a new country, city, or customer segment with an existing product.
- Before launching a new product line, to check that real, reachable demand exists.
- Ahead of an annual strategy or budget cycle, to re-test assumptions about growth, competitors, and pricing.
- When a competitor, regulation, or technology shift changes the assumptions an earlier analysis relied on.
- As supporting evidence in board decks, grant applications, and M&A due diligence.
How to apply it.
A repeatable step-by-step procedure, the underlying formula where one exists, and a worked example using illustrative numbers.
Step by step
- Define the market precisely: one product or service category, one customer type, one geography, and a time horizon. A market defined too broadly ("software") cannot be sized or analyzed usefully.
- Gather secondary data first: government and trade-association statistics, company filings, analyst reports, and any prior in-house research, to build a baseline before spending on primary research.
- Add primary research where secondary data cannot answer your specific question: customer interviews, surveys, expert calls, or store or website audits.
- Size the market using at least two independent methods, commonly top-down from an industry total and bottom-up from customer counts and spend, and reconcile the two.
- Segment the market by customer type, need, or geography, and identify which segment or segments are actually reachable and profitable for your business (this is where SAM and SOM narrow down from TAM).
- Map the competitive and supply structure: who serves this market today, how concentrated it is, and what it costs to enter or to keep serving customers.
- Scan the external environment (regulatory, economic, technological, social) for factors that could change demand or the cost of competing, for example with a PESTLE pass.
- Synthesize findings into a documented view: market size and growth, target segment(s), competitive position, key risks, and a recommendation, with every figure attributed to its source and date.
Formula
Top-down: Serviceable Market = Total Addressable Market (TAM) x Segment Relevance % x Reachable Geography/Channel %
Bottom-up: Market Size = Number of Target Customers x Average Annual Spend per Customer
If the two approaches land within roughly 20-30% of each other, the estimate is usually sound. A wider gap signals a bad assumption in one of the two methods.
Worked example
All figures below are illustrative, for demonstration only, and are not a real market estimate.
Suppose you are analyzing the market for cloud-based inventory-management software sold to mid-sized retailers (100 to 500 employees) in a single country.
Top-down: industry reports put the total business-software market in that country at $40 billion. Inventory-management software is estimated at 3% of that total, or $1.2 billion. Mid-sized retailers make up roughly 25% of buyers in that category, giving a top-down serviceable market of about $300 million.
Bottom-up: there are an estimated 15,000 mid-sized retailers in the country. Interview and survey data suggest 40% (6,000) would consider adopting cloud inventory software within three years, at an average contract value of $12,000 per year. That gives a bottom-up estimate of 6,000 x $12,000 = $72 million for the segment likely to buy soon, rising toward the $300 million top-down ceiling as adoption matures across the rest of the market.
Because the two methods land in the same order of magnitude, and the gap is explained by adoption timing (near-term buyers versus the full addressable segment) rather than by a modeling error, the analyst can present both numbers with that reasoning instead of picking one arbitrarily. The next step is to line up the two or three leading competitors already serving this segment and estimate what share of the roughly $72 million near-term pool is realistically winnable given their entrenchment; that share is the SOM.
