In our final step, we’ll calculate our SOM by making assumptions about what percentage of the SAM is obtainable. In the next part of our TAM sizing training exercise, we can now calculate the TAM, SAM, and SOM, i.e. a “top-down” revenue build. In particular, the top-down build is most applicable for early-stage to growth-stage companies, where the unit economics (or operating drivers) are not yet reliable enough for a bottom-up build to be applied.

We also explore the difference between total, serviceable, and obtainable markets—and how to use these metrics to build realistic growth plans.
Bottom-up market sizing starts small, then gradually gets built up. Then, estimations are made using assumptions (and market research) to establish growth and size.

Once you have an idea of the size of your market, you can estimate the market potential, or market volume. Market volume describes the total amount of potential transactions that you could make within a specified period of time such as per day, per month, per quarter or per year. In order to estimate your market volume, you need to know the penetration rate of your product or service. So, in this example, the estimated market size for the new smartphone charger in the target market is $10,000,000. This means that if all 1,000,000 people in the target market were potential customers and each spent an average of $10 on the charger, the total market size would be $10 million.

So, now you know that your current market value is $360,000 and you have penetrated just 6% of your target market in one month of operation. This means that, if you are able to double your market penetration in your second month of operation, you could increase your market value to $720,000.
