What AI bill should I expect at launch?
Teams about to launch use this to estimate the AI bill to expect at launch. Because AI cost scales with usage, doubling users roughly doubles spend unless you change the model or the token budget — this page shows the curve so you can plan the levers.

Why this isn't trivial
The part people underestimate: launch usage is uncertain, so the bill hinges on how many users actually engage the AI features versus sign up. In practice the biggest savings come from modeling a conservative and an optimistic activation scenario, so it is worth modelling before you commit.
How it's calculated
We estimate this by multiplying expected active users by per-user AI cost for the launch month. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
How do I estimate before any data?+
Use per-user cost times a range of activation rates to bracket the bill.
What if launch goes viral?+
Have a cheaper-model fallback ready so a spike doesn't blow the budget.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
