Calculating market size by TAM, SAM & SOM [Most common method]

There are several ways to calculate the market size, but using TAM, SAM & SOM is the most common & known method. What are TAM, SAM & SOM?

  • Total Addressable Market (TAM): This method calculates the total market demand for a product or service. It includes all potential customers and revenue opportunities.

  • Serviceable Available Market (SAM): This method calculates the portion of the TAM that a company can realistically target and serve.

  • Serviceable Obtainable Market (SOM): This method calculates the portion of the SAM that a company can realistically capture through its own efforts. Basically, the market share it can capture.

Confused? No problem, let’s look at an example of a water bottle business for a better understanding.

In the Total Addressable Market (TAM), you would look at the total market size for all water bottles sold globally. This would include all types of water bottles, from plastic to metal, and all sizes, from small to large.

To calculate the Serviceable Available Market (SAM), you would look at the portion of the TAM that your business can realistically serve, based on factors such as location, distribution channels, and target customer segment. For example, if your water bottle business is only selling online and only targeting customers in North America, your SAM would be the total market size for water bottles sold in North America online.

Finally, to calculate the Serviceable Obtainable Market (SOM), you would look at the portion of the SAM that your business can realistically capture, based on factors such as marketing budget, competitive landscape, and business model. For example, if your water bottle business has a limited marketing budget and faces strong competition, your SOM may be a smaller portion of the total North American online water bottle market.

Note: When calculating market size, it is important to consider factors such as the size and growth of the market, the target customer base, and the competition. Additionally, it is important to use reliable data sources and to clearly explain the methodology used in the calculations.

Other methods to calculate the market-size

Beyond TAM, SAM, and SOM, there are additional techniques to determine the size of your market.

  • Market Segmentation: This method involves dividing the market into smaller segments based on characteristics such as demographics, behavior, or needs.

  • Market Surveys: This method involves conducting surveys to gather data on the size of the market and consumer behavior.

  • Industry Reports: This method involves analyzing industry reports to understand market size and trends.

  • Historical Sales Data: This method involves analyzing your company’s historical sales data to estimate the size of the market.

  • Bottom-up approach: This method involves estimating the market size by starting with the number of potential customers and multiplying it by the average revenue per customer.

  • Expert Opinion: This method involves consulting with experts in the industry to gather their opinion on the size of the market.

How to craft a winning market-size slide? [Expert tips by an agency]

1. Paint the big picture

Set the stage by starting your slide with an overview of the total market size, and then break it down into smaller segments or sub-markets that are relevant to your product or service. Give your audience a sense of the vastness of the market and how your product or service fits into it.

2. Use visuals to tell a story

Use charts, graphs, and infographics to bring the market size to life and help illustrate the size and growth of the market. This will make the information more easily digestible for your audience and will help them understand the potential of your product or service.

3. Cite your sources and add credibility

Be sure to include information on where you sourced your market data from, and make sure it’s from reputable sources. This will add credibility to your presentation and give your audience confidence in the information you are providing.

4. Highlight your target market

Make sure to focus on the specific segment of the market that your product or service is targeting. This will help your audience understand the potential size of your addressable market and how it aligns with your product or service.

5. Show the growth potential

If the market is projected to grow in the future, be sure to highlight this growth potential. This will help demonstrate the potential for your business to grow along with the market and the potential for success for your product or service.

6. Keep it simple yet effective

Avoid overwhelming your audience with too much data or information. Stick to the most important and relevant information, but make sure it’s presented in an effective way that will capture the audience’s attention.

7. Make it visually appealing

Make sure that the slide is visually appealing and easy to read. Use colors, imagery, and design elements that will capture the attention of your audience and keep them engaged and interested in the information you’re presenting.
