How to Calculate SOM (Serviceable Obtainable Market)
Understanding Market Share and SAM
To begin calculating SOM, you must first determine your company's market share from the previous year. This involves analyzing market sales data relative to your company’s sales. Next, assess this year's Serviceable Available Market (SAM), which represents the portion of the total available market that your business can serve. SAM calculation requires identifying customers well-suited to your products or services and estimating their average annual spending.
Calculating SOM
Once you have established the market share and this year's SAM, calculate SOM by multiplying the two. Use the formula SOM = Last Year's Market Share × This Year's SAM. This approach provides a realistic projection of the segment of the market you can potentially acquire this year, based solely on present conditions and company performance.
Required Tools and Resources
To effectively perform these calculations, you will need specific tools and resources. A calculator, market research reports, and government or trade association data are essential for accurate analysis. Online tools that analyze competitors and customer search behavior can offer valuable insights. Additionally, accessing financial reports from publicly listed companies or employing market research firms can furnish crucial data to support your calculations.
Importance of Market Research and Analysis
Advanced market research is vital in determining both SAM and SOM accurately. Techniques such as a bottom-up analysis, where you start with the most fundamental data and build upwards, are crucial. Gathering comprehensive data about potential customers and current industry performance shapes a more detailed and effective market penetration strategy.
Summary
Calculating SOM is an integral part of strategic planning for startups looking to understand their potential in specific markets. By meticulously analyzing past performance related to broader market possibilities, companies can set realistic acquisition targets and improve their market strategies based on solid analytical foundations.
How to Calculate SOM
Understanding the Serviceable Obtainable Market (SOM) is crucial for businesses aiming to pinpoint their effective market reach. The SOM represents the portion of the market your products or services currently capture.
Determine Market Share
Begin by determining your company’s market share from the previous year. This involves assessing what percentage of the market you served or how many units of product you sold compared to the total market.
Estimate This Year's SAM
Next, calculate this year's Serviceable Addressable Market (SAM). SAM is defined as the segment of the Total Addressable Market (TAM) that your products or services can reach. Depending on available data, use either the top-down, bottom-up, or value theory approach to estimate TAM, then narrow down to identify the SAM.
Calculate SOM
Multiply your determined market share by this year’s SAM value to find SOM. Use the formula SOM = Market Share × SAM. For instance, if your market share last year was 10% and the SAM for this year is $500,000, the SOM is calculated as SOM = 10% × $500,000 = $50,000.
This calculation offers a realistic assessment of your obtainable market based on current service capacity and market conditions.

How to Calculate SOM
Calculating the Self-Organizing Map (SOM) involves several steps, including initializing weights, competitive learning, and weight adjustment. Below are examples illustrating these key processes in creating and utilizing a SOM.
Example 1: Initializing Weights
Initialization sets the starting point for SOM training. Assign random values to the weight vectors for each neuron in the map, ensuring they match the dimensionality of the input vectors. For instance, if the input vector is two-dimensional, each weight vector might start as w = [0.6, 0.4].
Example 2: Competitive Learning
The core of the SOM algorithm is competitive learning, where each input vector is compared to all weight vectors. The neuron whose weight vector is closest to the input vector wins. For an input v = [0.8, 0.2], and two neurons with weights w1 = [0.7, 0.3] and w2 = [0.4, 0.6], w1 is closer to v, making it the winning neuron.
Example 3: Weight Adjustment
After identifying the winning neuron, adjust its weight vector to make it even closer to the input vector. This adjustment is guided by the learning rate and the neighborhood function. For the winning neuron with initial weight w = [0.7, 0.3], a learning rate of 0.1, and the input v = [0.8, 0.2], the new weight would be calculated as w' = w + 0.1 * (v - w), resulting in w' = [0.71, 0.29].
Example 4: Iterative Process
Repeat the competitive learning and weight adjustment steps for numerous iterations or until convergence. Each iteration refines the SOM, improving its topology preservation and feature mapping capabilities. This iterative process is fundamental to the training of a self-organizing map.
