What it means
At its core, market analysis answers four questions: how large is the market, how fast is it growing, who buys and why, and who else is selling. The output is usually a short written assessment sitting on top of a sizing model that anyone can inspect and challenge.
It belongs in a business plan, an investment paper or a strategy review. It matters because most expensive strategic mistakes come from assuming demand rather than measuring it.
A properly built analysis reveals whether a plan quietly depends on capturing an unrealistic share of the available market, which is one of the first things an experienced investor tests. The standard sizing frame is TAM, SAM and SOM: total addressable market, serviceable addressable market and serviceable obtainable market.
Each narrows the one before it, first by product fit and geography, then by realistic share given your sales capacity and competition. There are two ways to build the numbers.
Top-down starts from a published industry total and cuts it down with percentages, while bottom-up counts potential customers and multiplies by realistic spend per customer. Bottom-up is the version investors trust, because every assumption is visible and can be argued with individually.
Sizing is only half the job. The rest covers competitive structure, buyer behaviour, pricing benchmarks, distribution routes and any regulatory or technology shifts on the horizon.
Together those tell you whether profit in that market is defensible or whether it will be competed away.
In practice
Real-world examples.
Example
A fitness equipment brand considering entry into a new country counts gyms and studios in that market, multiplies by average annual equipment spend, and finds the serviceable market is only a third of what a published headline figure suggested. It scales the launch budget accordingly.
Example
A fintech start-up preparing a funding round presents a bottom-up sizing built from company registry data and published average spend. Investors accept the numbers precisely because each assumption is separately visible, in contrast with an earlier deck that simply claimed a share of a large global figure.
Example
A packaging manufacturer reviewing whether to keep a product line finds the market has been shrinking by roughly 4% a year as customers switch materials. The analysis prompts a decision to harvest the line for cash rather than reinvest in new machinery.
Think of it
“Market analysis is studying the playing field-understanding the market before you compete in it.
Formula
Calculation
TAM = Number of Potential Customers x Average Annual Revenue per Customer
SOM = SAM x Realistic Market Share
A company sells a compliance tool to accountancy practices. Research identifies 40,000 practices that could use it, at an average annual contract value of $6,000.
TAM = 40,000 x $6,000 = $240,000,000.
Only 12,000 of those practices are in the countries the company can currently serve and are large enough to need the product, so:
SAM = 12,000 x $6,000 = $72,000,000.
Given a small sales team and two established competitors, a realistic share within three years is 5%:
SOM = $72,000,000 x 0.05 = $3,600,000.
That $3,600,000 is the figure the three-year plan should be built on. It also implies roughly 600 customers, because $3,600,000 / $6,000 = 600, which the team can then sanity-check against how many deals each salesperson can realistically close in a year.Case study
Seen in the real world.
The following is an illustrative and clearly fictional example. Ridgepoint Analytics, an invented software company, planned to launch a scheduling tool for veterinary practices. Its first business case cited a $2,000,000,000 "practice management software market" and assumed the company would take 1% of it within three years, producing a $20,000,000 revenue target.
A non-executive director asked for a bottom-up rebuild. Counting actual veterinary practices in the target countries, applying a realistic average contract value and allowing for the share already locked into multi-year contracts with two incumbents, the serviceable market came out at $48,000,000 and a realistic three-year share at 6%, or roughly $2,900,000.
Ridgepoint kept the project but resized everything around it: a smaller sales team, a narrower launch and a funding request one-seventh the size of the original. The illustrative lesson is that a large headline market number is not an opportunity; the opportunity is the part you can actually reach and win.
Watch out
Common mistakes.
- Quoting a huge global market figure and assuming a share of it. A market you cannot reach with your current product, licences and sales capacity is not addressable, however large it is.
- Relying entirely on top-down percentages. Cutting a published total by convenient-looking percentages produces a number that cannot be checked and that experienced readers discount immediately.
- Treating the analysis as a one-off document. Markets, competitors and prices move, so a sizing model that has not been refreshed in two years is often more misleading than having none.
Questions
People also ask.
How often should a market analysis be updated?
Once a year for a stable market and every quarter in a fast-moving one, with the sizing assumptions revisited whenever actual sales differ sharply from the model.
What is the difference between market analysis and market research?
Market research gathers the raw evidence such as surveys, interviews and data purchases, while market analysis interprets that evidence into a sized, structured view of the opportunity.
Is competitor information really necessary?
Yes, because market size alone says nothing about whether you can win any of it; pricing pressure and incumbent contracts often matter more than the total available spend.
