Market Size for SaaS in 2026 [Example]

The total available market (TAM) for SaaS products globally is estimated at around $300 billion. This figure is based on the growing reliance of businesses across various industries on cloud-based software solutions. With approximately 600 million businesses worldwide, a conservative estimate considers many small to medium-sized enterprises (SMEs) that increasingly adopt SaaS, equating to a vast market of potential users beyond just corporate giants.

These businesses range from marketing, finance, healthcare, and education sectors, all of which have different SaaS needs, indicating a significant market size that includes every person associated with these businesses who might use SaaS solutions.

The serviceable addressable market (SAM) for my specific SaaS product, tailored for small businesses and solopreneurs, is estimated at $60 billion. This figure focuses on small to medium-sized businesses that specifically require SaaS solutions, which accounts for about 20% of the total SaaS market. Considering the number of small businesses worldwide is approximately 120 million, this allows us to target an audience that is more aligned with our product, ensuring a reachable segment of the overall market.

I assume that the average spending per small business on SaaS solutions is about $500 annually, which includes various tools and subscriptions that enhance productivity and operational efficiency without overestimating their budgets.

The serviceable obtainable market (SOM) represents the share of the SAM that I can realistically capture within the first year. I estimate this to be around $3 million, assuming we can acquire about 6,000 customers. This calculation is based on a conservative market penetration rate of 0.005% given the competitive nature of the SaaS sector and the limited marketing budget for a small business.

With the average revenue of approximately $500 per customer each year, this results in $3 million. This is a realistic target for a solopreneur entering the market, focusing on agile marketing strategies and building strong customer relationships to yield steady growth.
