Calculate Market Size with SurveyMars

Understanding what is market size is a fundamental step for any business, from startups seeking investment to established companies launching new products. Market size is the total volume or value of a specific market, and accurately calculating it is critical for assessing opportunity, allocating resources, and convincing stakeholders. While topdown research using industry reports is common, a more accurate and targeted approach involves gathering data directly from your potential customers. This is where SurveyMars becomes an indispensable tool, enabling you to move from abstract estimation to datadriven calculation.

Defining Your Target with Customer Profiles

Before you can calculate anything, you must define who you are selling to. This is the process of building detailed customer profiles (or buyer personas). Use SurveyMars to create a screening survey that helps you segment the total population into your target audience. This survey should include demographic questions (age, income, location), psychographic questions (interests, values), and, most importantly, behavioural questions related to your product or service (e.g., "How often do you purchase organic skincare products?"). Distributing this survey widely helps you understand the proportion of the general population that fits your ideal customer profile.

The SurveyMars Approach to Market Sizing

How to calculate market size typically involves two main figures: Total Addressable Market (TAM) and Serviceable Addressable Market (SAM). SurveyMars helps you gather the data needed for both.

1.  Estimating Total Addressable Market (TAM): Your TAM is everyone who could possibly buy your product. To estimate this with SurveyMars, create a survey designed to measure demand. Include questions like:

"How likely are you to buy a product that does [X]?" (on a 15 likelihood scale).

"How much would you expect to pay for this?"

"How often would you make this purchase?"

By applying the percentage of positive responses (e.g., those answering 4 or 5 on likelihood) to the total population of your target region, you can estimate the number of potential customers. Multiply this by the expected annual spend per customer to get a valuebased TAM.

2.  Refining to Serviceable Addressable Market (SAM): Your SAM is the segment of the TAM you can actually reach with your distribution channels. Your initial customer profile survey already helps define this. Use SurveyMars to further refine this by asking about shopping habits (e.g., "Where do you typically buy these products: online, in specialty stores, or in bigbox retailers?"). If you are an onlineonly business, your SAM is the portion of your TAM that prefers to shop online. This creates a more realistic and achievable market size figure.

Turning Insights into Action

SurveyMars doesn't just collect data; it helps you analyze it. The platform’s reporting dashboard allows you to filter responses, crosstabulate data (e.g., viewing purchase intent by age group), and export everything for further analysis in spreadsheets. The key to accurate market sizing is the quality of your questions and the reach of your survey. By strategically deploying surveys with SurveyMars, you transform vague guesses into a validated, databacked estimate of your business opportunity, providing a solid foundation for your entire business strategy.
