Market Size for Small business in 2026 [Example]

The total addressable market includes all small businesses worldwide. According to the World Bank, there are approximately 300 million small businesses globally. Assuming an average annual spending of $1,000 on products or services that support small business operations, this leads to a TAM of around $300 billion.

This figure captures a wide array of sectors such as retail, service industries, and online businesses. Each small business is likely connected to various products, making this a substantial market that extends well beyond just a single niche within small business solutions.

Considering your product focuses on a specific niche within the small business market, the serviceable addressable market is estimated at 5% of the overall TAM. This aligns with a realistic reach given the niche nature of the product and competition levels.

From the 75 million small businesses globally, targeting businesses likely to spend on your specific product brings you to around 15 million. These businesses would realistically be looking for solutions in your niche, bringing the SAM to approximately $15 billion.

In the first year, realistically capturing about 0.5% of the SAM is a conservative and attainable goal. This translates to approximately 15,000 customers converting to your offerings.

Assuming an average annual spend of $5,000 per customer for your product, the SOM could amount to $75 million. This projection considers initial marketing efforts, brand building, and the time needed to establish a customer base in a competitive marketplace.
