AI SaaS Profitability Calculator
Every AI builder eventually asks: at $19/mo with users sending 50 messages a day, am I making money or losing it? Enter your numbers and find out, with the break-even point spelled out.
Why AI SaaS margins are different
Traditional software costs roughly the same whether a user logs in once or a thousand times. AI is the opposite: every message costs you tokens, so your costs scale with usage, not just headcount. That’s why a price that looks fine on paper can quietly lose money once power users start hammering the model. This calculator makes that visible: revenue, API cost, gross margin, and the break-even point, the usage level where a paying user stops being profitable.
The honest caveats
- The default prices are illustrative tiers (as of June 2026), editable. Put in your model’s real numbers.
- Real token counts are usually higher than you think: system prompts, conversation history, RAG context, and retries all add tokens. Estimate a single call with the Token Counter.
- This is gross margin on model cost. It ignores salaries, marketing, and Stripe fees, real businesses have more costs than tokens.
FAQ
Is this a real quote for my model?
No. The tiers are round-number bands reflecting common pricing, not a live price sheet. Every field is editable, paste your provider’s actual per-million-token rates for an accurate result.
What's the "break-even messages" number?
The messages-per-day at which one paying user’s token cost equals what they pay you. Below it you profit on that user; above it you lose money on them. It’s the single most useful number for pricing an AI product.
How do I handle a free tier?
Set the “on free tier %.” Free users generate token cost but no revenue, so they drag your margin. The calculator shows how much that free usage is costing you.
