Pricing an AI SaaS: Cover Your Costs and Keep Your Margin
Unlike traditional software, AI features carry a real variable cost per use. That changes how you price: a flat subscription can lose money on heavy users, and a generous free tier is pure cost until it converts. This guide covers pricing an AI product so it stays profitable.
Price against heavy users, not the average
A small share of power users often drives most of your AI cost. If you price on average usage, those users erode your margin. Either price for the heavy tail, add fair-use limits, or introduce usage-based charges above a threshold.
Flat vs usage-based
Flat pricing is simple and predictable but exposes you to heavy usage; usage-based pricing tracks cost closely but can deter engagement. Many products combine them: a predictable subscription with fair-use caps or metered overages.
Free tiers and margin targets
Free users generate cost with no direct revenue, so size the free allowance to your conversion rate and serve it with a cheaper model. To hit a target gross margin, divide your per-user AI cost by (1 − target margin) to find the minimum price.

Frequently asked questions
How should I price an AI feature?+
Cover your per-request AI cost plus overhead, apply a target margin, and protect against heavy users with caps or usage-based pricing.
Can I offer unlimited AI usage?+
Only if you model the heavy tail — most 'unlimited' plans quietly carry fair-use limits to stay profitable.
