Does each user pay for the AI they burn — or quietly eat your margin?
Unlike fixed-cost software, an AI app can lose margin as it grows if usage outpaces price. Forecast where the bill is heading on the API cost forecast calculator, and break down a single chat session on the chatbot cost calculator.
Free AI cost-per-user calculator — split your monthly AI bill across active users and see the gross margin left after each user pays their price.
Because AI is a usage-based cost of goods sold, not a fixed expense. Traditional SaaS margins improve with scale; an AI app can see margins shrink if per-user token usage grows faster than price. Cost per user tells you whether each customer is actually profitable at your current pricing.
Cut cost per user (smaller or cheaper models for easy requests, caching, batching, capping heavy usage) or raise price/usage limits. Watch power users and free tiers especially — a small fraction of heavy users often drives most of the bill, so usage caps or tiered pricing protect the margin.
