Token usage → gross margin + breakeven, instantly
It answers one question: given your model pricing, token usage, and what you charge users, what is your gross margin per user and how many users do you need to cover your fixed costs?
This tool does not calculate LTV, CAC, churn, runway, or investment projections. It is a gross margin and breakeven calculator — nothing more.
The number of times a single user calls your AI feature in a month. If a user sends 5 chat messages per day and your app runs for 30 days, that's roughly 150 requests.
Input tokens are the tokens in your prompt (system prompt + user message). Output tokens are the tokens in the model's response. Providers charge different rates for each. Enter the average per request.
Prices are sourced from provider documentation and updated periodically, but they change. Always verify against your provider's current pricing page before making decisions. Use the Custom option to enter your own figures.
Any non-API cost that scales with users — for example, third-party data lookups, per-user storage fees, or support costs. Leave it at 0 if you only have API costs.
The minimum number of paying users at your current pricing where your gross profit covers your fixed monthly costs. If your gross profit per user is zero or negative, breakeven is not reachable at that pricing.
