Subscription businesses are often discussed in terms of monthly recurring revenue, but the underlying unit economics vary dramatically depending on the model. Understanding these differences is essential for anyone evaluating or building a subscription-based business.
At the lower end of the pricing spectrum, a SaaS product charging $49 per month requires a substantial user base to generate significant revenue. At that price point, reaching $100,000 in monthly recurring revenue requires approximately 2,041 paying customers. Assuming a typical free-to-paid conversion rate of 2 to 5 percent, this implies a free user base of 40,000 to 100,000. Products like PDF.ai and Chatbase have demonstrated that this is achievable in growing markets with strong organic search traffic.
Mid-tier SaaS products, priced between $99 and $299 per month, target a different segment. These tools typically serve business users who can justify the expense based on measurable productivity gains or cost savings. The customer base needed is smaller, but the sales cycle tends to be longer and may require more hands-on onboarding.
At the premium end, subscription models priced at $500 or more per month — including professional communities, coaching programs, and enterprise tools — require far fewer customers but demand a higher level of trust and demonstrated value. The economics are attractive on paper, but customer acquisition at this price point typically requires a strong personal brand or established reputation.
The agency retainer model represents another variation. Service businesses that charge monthly retainers — particularly those using AI tools to increase their output capacity — operate on a different set of economics. The revenue per client is higher, but so is the operational complexity.
A less commonly discussed model is the portfolio approach, where a builder operates multiple smaller subscription products simultaneously. Rather than concentrating risk in a single product, this strategy distributes it across several. The BoredHumans case is one example of this approach in practice.
Across all these models, the fundamental advantage of subscription revenue is its compounding nature. Each month's new customers add to the base of existing subscribers, creating a growth curve that accelerates over time — provided that churn remains manageable. The businesses that succeed tend to be those that focus as much on retention as on acquisition.
