Can I offer an unlimited AI plan profitably?
Pricing an AI feature means working backwards from cost, and this tool helps teams tempted by unlimited plans test whether an unlimited AI plan can be profitable. It ties your per-request AI spend to the price and margin you set, so you can see the trade-off before you publish a price.

Why this isn't trivial
The part people underestimate: unlimited plans are priced on averages but abused by the heavy tail, so a few power users can wipe out the margin. In practice the biggest savings come from adding soft fair-use limits behind the 'unlimited' label, so it is worth modelling before you commit.
How it's calculated
We estimate this by comparing plan price against the AI cost of heavy-user behavior, not the average. 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
Is truly unlimited safe?+
Rarely — model the heavy tail; most 'unlimited' plans carry fair-use limits.
How do I make unlimited work?+
Price for heavy users or throttle abuse while keeping the plan generous.
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.
