AI model cost calculator FAQ

How does the AI model cost calculator work?

Choose a usage scenario, set monthly traffic and token assumptions, then ModelMeter estimates monthly, annual, per-user, and per-task cost from source-labeled model pricing records.

Are cached input, batch API, and tool costs included?

The calculator includes cached input, batch, web search, and retry controls when source-backed price fields exist. Missing price dimensions are shown as warnings instead of being silently guessed.

Can I use this for production budget planning?

Use ModelMeter for early planning and team discussion. Final procurement decisions should verify provider pricing, discounts, caching, batch pricing, regional terms, and contract terms.
