Estimate the cost of an LLM API call from input and output token counts, using published Claude model pricing. Everything runs entirely in your browser.
How it works
Enter your input and output token counts and choose a Claude model. This tool multiplies by that model’s published per-million-token price and shows input cost, output cost, and total separately.
FAQs
Are these prices always current?
Prices are current as of when this tool was built. LLM providers revise pricing periodically — verify current rates before relying on this for budgeting decisions.
Why only Claude models?
This first version covers Claude models, which we could verify pricing for directly. Support for other providers may be added later.
Is my data sent anywhere?
No. The calculation happens entirely in your browser.
