Frequently asked questions

How much does an LLM feature actually cost per month?

Cost depends on the model, input and output token volume, and monthly active users. An LLM cost calculator gives you the order of magnitude in seconds: at identical volume, the gap between GPT, Claude and Gemini often exceeds a factor of 10. The calculator above estimates this from published per-million-token pricing.

How do you calculate AI cost per user?

Your AI cost per user is total token spend divided by active users over the period. It is the decisive metric when you bill a flat subscription: revenue is fixed, cost is variable. A handful of power users is enough to push an entire plan below break-even.

What margin should an LLM feature target?

A 70% gross margin after token costs is the commonly accepted SaaS benchmark. An LLM margin calculator does more than display cost: it pinpoints the lever to move — switch model, adjust price, or cap usage — to get back above the threshold. Cost alone does not tell you what to do; margin does.
