Calculate AI API Cost

Estimate prompt tokens, output tokens, per-call API cost, monthly spend, and how many calls fit inside a budget. Pricing is a practical snapshot for popular text-generation APIs, with a custom model option for anything not listed.

Prompt and Usage

Token counts are estimates. Your provider's API usage response is the billing source of truth. Currency conversion uses the exchange rate you enter so the calculator remains useful for every ISO currency without relying on live financial data.

How to use

  • Paste or upload your prompt text.
  • Choose a model, expected output size, currency, and budget.
  • Review the cost per call, monthly estimate, and calls available within budget.
  • Use the custom pricing fields for enterprise rates or models not listed. Select Custom under Model provider and then update the Custom input $/1M, Custom output $/1M.

Is this exact billing?

No. It is an estimate for planning. Exact billing depends on provider tokenization, cached tokens, tools, search, batch discounts, regional pricing, taxes, and the usage values returned by the API.
