Frequently asked questions
What does "save scenarios" actually mean?+
A named snapshot of your inputs (MAU, pricing, model, feature mix) that you can pull up later without re-typing. Saved to your account — not to your browser — so you can access them anywhere.
Does this work with non-OpenAI models?+
Yes. Anthropic (Claude 3.5, 3.7, Opus 4), Google (Gemini 1.5 / 2.0), Meta (Llama 3.1 / 3.3), Mistral, DeepSeek, and custom pricing for self-hosted or negotiated rates. We update pricing within a week of any provider change.
What happens to my saved scenarios if I cancel?+
You keep read-only and export access for 30 days after your subscription ends. After that, scenarios stay in your account but become read-only until you resubscribe. We never delete your data.
Are the PDF exports actually investor-ready?+
Yes — clean typography, your scenario name, the inputs you used, the model(s) compared, a margin chart, and a methodology note at the bottom so the person reading it knows what they're looking at. Founders have used these in seed and Series A decks.
Will the free tier stay free forever?+
Yes. The core calculations — margin, CPAU, breakeven — will always be free. The Free tier may change at the edges (e.g., we may add things to it), but we're not going to take the calculator away from you.

Founders who got their margin back
Real stories from teams that opened the calculator and changed how they price their AI product.
“Plugged in our actual GPT-4o usage and saw our 'healthy' margin was actually 31%. Switched feature mix to Haiku for the cheap path, kept 4o for the premium tier — back to 68% in a week. This tool paid for itself the day I opened it.”
Maya Okafor
Co-founder & CTO, Lumen AI
“Our board was asking why CAC payback got worse. The power-user table here surfaced it in two minutes — top 8% of users were burning 5x our blended estimate. We capped them and the math came back.”
Daniel Reyes
Founder, Foundry Labs
“I was about to launch at $9/mo. Ran it through the simulator at our projected token usage and realized I'd lose money on every paid user past 2,000 MAU. Repriced to $19 before launch. Saved my runway.”
Priya Shah
Solo founder, Northwind
“Best $19 I spend each month. The PDF export went straight into our Series A deck — investors actually engaged with the unit-economics slide for once.”
Tom Bergmann
CEO, Parallax
