Tap into this business growth method to explore your market \u2014 and find where your best-fit customers really are.<\/strong><a href=\"http:\/\/www.linkedin.com\/shareArticle?mini=true&amp;url=https%3A%2F%2Fwww.salesforce.com%2Fblog%2Fsmall-business%2Ftam-sam-som%2F%3Futm_source%3DLinkedIn%26utm_medium%3Dorganic_social%26utm_campaign%3Dus_cbaw%26utm_content%3Dblog-ctt&amp;title=TAM%2C%20SAM%2C%20and%20SOM%3A%20Made%20Simple%20for%20Growing%20Businesses\" target=\"_blank\" rel=\"noreferrer noopener\"><\/a><\/p>\n\n\n\n<p>What do TAM, SAM, and SOM have in common? They all have your market in mind for growing your business. The size of a potential market is a key consideration in many business decisions. It can determine how much product to make, how much to invest in&nbsp;<a href=\"https:\/\/www.salesforce.com\/small-business\/marketing\/smb-marketing-guide\/\">small business marketing<\/a>, how things are priced, and ultimately, how much money you make. If businesses don\u2019t calculate the size of the market correctly, there can be a big disconnect between investing and how much it can pay off.<\/p>\n\n\n\n<p>In this quick guide, we\u2019ll break down what TAM, SAM, and SOM mean, why they matter for testing&nbsp;<a href=\"https:\/\/www.salesforce.com\/blog\/best-small-business-ideas\/\">small business ideas<\/a>, and how to calculate them effectively.<\/p>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-understanding-tam-sam-and-som\">Understanding TAM, SAM, and SOM<\/h2>\n\n\n\n<p>TAM, SAM, and SOM are metrics that help businesses understand the potential size of their market and set realistic goals for growth.&nbsp;<\/p>\n\n\n\n<p>Imagine you\u2019re planning a big party. You wouldn\u2019t order food for every person in town \u2014 you\u2019d first estimate how many guests might attend. Then, you\u2019d consider their dietary preferences, portion sizes, and allergies to avoid waste and ensure everyone is satisfied.<\/p>\n\n\n\n<p>Similarly, before your&nbsp;<a href=\"https:\/\/www.salesforce.com\/small-business\/what-is-an-smb\/\">small and medium-size business (SMB)<\/a>&nbsp;invests in marketing or product development, you need to know the size and composition of the market before you can make a plan and&nbsp;<a href=\"https:\/\/www.salesforce.com\/small-business\/marketing\/capture-leads\/\">capture leads<\/a>. One way to do this is by calculating TAM, SAM, and SOM. Here\u2019s the quick breakdown:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>TAM (Total Addressable Market)<\/li>\n\n\n\n<li>SAM (Serviceable Available Market)<\/li>\n\n\n\n<li>SOM (Serviceable Obtainable Market)<\/li>\n<\/ul>\n\n\n\n<p>&nbsp;Let\u2019s start with TAM.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-what-is-tam\">What is TAM?<\/h3>\n\n\n\n<p>TAM stands for \u2018total addressable market\u2019 and means the total revenue opportunity available if your business were to capture 100% of the market demand for your product or service. In other words, it represents the maximum size of your market \u2014 before narrowing it down based on factors like competition or geography.<\/p>\n\n\n\n<p>For example, if you\u2019re launching a new video game aimed at kids aged 8 to 12, your TAM would be the total number of children in that age group who play video games, multiplied by the average amount spent on games per child. While this number can be exciting to look at, not every potential customer will end up buying \u2014 which is why it\u2019s just the starting point.<\/p>\n\n\n\n<p>Understanding TAM is especially helpful when using advanced tools like&nbsp;<a href=\"https:\/\/www.salesforce.com\/artificial-intelligence\/\">Salesforce AI<\/a>&nbsp;to explore market trends and uncover high-potential segments to focus your efforts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-what-is-sam-nbsp\">What is SAM?&nbsp;<\/h3>\n\n\n\n<p>SAM stands for \u2018serviceable available market\u2019 and is the portion of the total market your business can realistically serve. It\u2019s based on factors like competition, geography, production capacity, and demographics. SAM gives you a clearer picture of your actual target audience \u2014 the people you\u2019re most likely to reach and sell to.<\/p>\n\n\n\n<p>For example, if you run an online jewelry business, your TAM would be the entire jewelry market. But your SAM might be young, professional women in a middle-income bracket who are more likely to buy your designs \u2014 rather than those shopping for high-end luxury pieces.<\/p>\n\n\n\n<p>Using AI-driven insights from&nbsp;<a href=\"https:\/\/www.salesforce.com\/\">Salesforce CRM<\/a>&nbsp;can help refine your SAM by identifying high-intent buyers and tailoring your&nbsp;<a href=\"https:\/\/www.salesforce.com\/small-business\/marketing\/\">marketing efforts<\/a>&nbsp;to the right audience.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-what-is-som\">What is SOM?<\/h3>\n\n\n\n<p>SOM stands for \u2018serviceable obtainable market\u2019 and means the portion of your SAM that your business can realistically convert within a specific timeframe. Factors like pricing, market trends, competition, and available resources \u2014 such as your marketing budget and&nbsp;<a href=\"https:\/\/www.salesforce.com\/sales\/\">sales<\/a>&nbsp;team size \u2014 influence how much of the market is truly within reach.<\/p>\n\n\n\n<p>For example, a&nbsp;<a href=\"https:\/\/www.salesforce.com\/saas\/\">software-as-a-service (SaaS)<\/a>&nbsp;startup helping restaurants reduce food waste might define its TAM as all restaurants. Its SAM could be multi-location restaurants with enough volume to benefit from the service. But its SOM \u2014 what\u2019s realistically attainable in the short term \u2014 might be environmentally conscious restaurants in one region, where demand and resources align.<\/p>\n\n\n\n<p>And, again,&nbsp;<a href=\"https:\/\/www.salesforce.com\/crm\/ai-crm\/\">AI-powered customer relationship management (CRM)<\/a>&nbsp;can help refine your SOM by predicting which customers are most likely to convert and optimizing marketing spend.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-calculate-tam-sam-and-som\">How to calculate TAM, SAM, and SOM<\/h2>\n\n\n\n<p>There are two ways to calculate market size with TAM, SAM, and SOM \u2014 from the top down or the bottom up. Let\u2019s find out what works best for you.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-top-down-market-sizing-approach\">The top-down market-sizing approach<\/h3>\n\n\n\n<p>The top-down approach relies mostly on external sources like industry reports, analyst&nbsp;<a href=\"https:\/\/www.salesforce.com\/data\">data<\/a>, and&nbsp;<a href=\"https:\/\/www.salesforce.com\/small-business\/how-to-do-market-research\/\">market research<\/a>, combined with some estimates and assumptions. You start with the total market and then narrow it down to estimate what portion your business could realistically capture.<\/p>\n\n\n\n<p><strong>Pros:&nbsp;<\/strong>The top-down approach works well when launching brand-new products or services, especially when you don\u2019t have much&nbsp;<a href=\"https:\/\/www.salesforce.com\/sales\/\">sales<\/a>&nbsp;or customer data yet. It\u2019s also a fast way to get a broad market overview for high-level planning.&nbsp;<\/p>\n\n\n\n<p><strong>Cons:<\/strong>&nbsp;This method is only as accurate as the data available. If the numbers are off, you could overestimate your potential market \u2014 or miss key insights that could shape your strategy.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-bottom-up-market-sizing-approach\">The bottom-up market-sizing approach<\/h3>\n\n\n\n<p>The bottom-up approach starts with&nbsp;<a href=\"https:\/\/www.salesforce.com\/data\">real sales data<\/a>, customer insights, and localized calculations. You then scale those numbers up to estimate your total market potential.<\/p>\n\n\n\n<p><strong>Pros:&nbsp;<\/strong>Because this approach is based on actual data \u2014 like reports from your&nbsp;<a href=\"https:\/\/www.salesforce.com\/crm\/crm-for-small-business\/\">small business sales software<\/a>&nbsp;\u2014 it tends to be more accurate.<\/p>\n\n\n\n<p><strong>Cons:&nbsp;<\/strong>It can be more time-consuming to research and calculate.&nbsp;&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-how-to-calculate-your-tam-sam-som-with-both-approaches\">How to calculate your TAM, SAM, SOM with both approaches<\/h3>\n\n\n\n<p>Let\u2019s break down how you can calculate TAM, SAM, and SOM with real-world business scenarios. Whether you\u2019re launching a&nbsp;<a href=\"https:\/\/www.salesforce.com\/saas\/\">software-as-a-service (SaaS)<\/a>&nbsp;product or&nbsp;<a href=\"https:\/\/www.salesforce.com\/small-business\/commerce\/\">opening a retail store<\/a>, these examples show how market sizing can guide your growth strategy.<\/p>\n\n\n\n<p><strong>Example 1: A retail business expanding into eco-friendly beauty (top-down approach)<\/strong><\/p>\n\n\n\n<p>Now, let\u2019s say you\u2019re opening a chain of stores that sell eco-friendly beauty products. Since you don\u2019t have&nbsp;<a href=\"https:\/\/www.salesforce.com\/data\">existing sales data<\/a>&nbsp;yet, you take a top-down approach instead:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Identify TAM:<br><\/strong>Research shows the U.S. eco-friendly beauty industry is worth $6.5 billion. TAM = $6.5 billion<\/li>\n\n\n\n<li><strong>Refine your SAM:<\/strong><br>You plan to sell only in physical stores, and 46% of beauty shoppers prefer to buy in person. SAM = 46%<br><br><em><strong>TAM ($6.5 billion) x SAM (46%) = $2.99 billion<\/strong><\/em><\/li>\n\n\n\n<li><strong>Find your SOM:<br><\/strong>This is a two part process. You\u2019re starting with a few stores in Los Angeles, where about 1% of the U.S. population lives. First, that gives you a starting point for your SAM:<br><br><strong><em>SAM ($2.99 billion) x SOM (1%) = $29.9 million<\/em><\/strong><br><br>And next, based on competition and your marketing plans, you estimate you can capture 10% of the Los Angeles market in the first phase.<br><br><strong><em>SOM = $29.9 million x 10% = $2.99 million<\/em><\/strong><\/li>\n<\/ol>\n\n\n\n<p>Your service obtainable market (SOM) is $2.99 million. Go get em\u2019!<\/p>\n\n\n\n<p><strong>Example 2: A project management SaaS startup (bottom-up approach)<\/strong><\/p>\n\n\n\n<p>Imagine you run a SaaS company that helps IT teams stay organized. After gaining traction, you decide to expand into the manufacturing industry. Here\u2019s how you might calculate TAM, SAM, and SOM using a bottom-up approach:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Estimate TAM:<br><\/strong>Start by identifying how many manufacturing businesses exist in the U.S. \u2014 roughly 600,000. Next, use your&nbsp;<a href=\"https:\/\/www.salesforce.com\/data\">existing customer data<\/a>&nbsp;to estimate the annual revenue per customer, which is $10,000.<br><br><strong><em>TAM = 600,000 businesses \u00d7 $10,000 per customer = $6 billion<\/em><\/strong><\/li>\n\n\n\n<li><strong>Determine SAM:<br><\/strong>You know that your software works best for manufacturers with 50\u2013100 employees who don\u2019t need much customization. Research shows that 200,000 businesses fit this profile.<br><br><strong><em>SAM = 200,000 businesses \u00d7 $10,000 per customer = $2 billion<\/em><\/strong><\/li>\n\n\n\n<li><strong>Find SOM:<\/strong><br>Based on past performance and your marketing strategy, you estimate that your&nbsp;<a href=\"https:\/\/www.salesforce.com\/sales\/\">sales<\/a>&nbsp;team can realistically acquire 1,000 new customers per year.<br><br><strong><em>SOM = 1,000 customers \u00d7 $10,000 per customer = $10 million<\/em><\/strong><\/li>\n<\/ol>\n\n\n\n<p>Both approaches \u2014 bottom-up for SaaS and top-down for retail \u2014 show that accurate data and&nbsp;<a href=\"https:\/\/www.salesforce.com\/crm\/ai-crm\/\">AI-powered market analysis<\/a>&nbsp;can help you refine your strategy. Whether you\u2019re using&nbsp;<a href=\"https:\/\/www.salesforce.com\/crm\/\">CRM software<\/a>&nbsp;to track leads or&nbsp;<a href=\"https:\/\/www.salesforce.com\/crm\/crm-for-small-business\/\">AI tools for small businesses<\/a>&nbsp;to analyze trends, your insights will shape smarter decisions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-tam-sam-and-som-matter-for-business-strategy\">Why TAM, SAM, and SOM matter for business strategy<\/h2>\n\n\n\n<p>Understanding TAM, SAM, and SOM provides a data-driven approach to business strategy, helping you attract investors and scale effectively. These market-sizing insights shape everything from revenue forecasts to marketing plans, making them essential for long-term success.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-how-startups-and-investors-use-tam-sam-and-som\">How startups and investors use TAM, SAM, and SOM<\/h3>\n\n\n\n<p>Both startups and their potential investors use these market-sizing exercises to evaluate the viability and potential of business ideas.
