Free AI agent cost calculator

Pick a model, enter the input tokens and output tokens for one task, and how many of those tasks you run in a day. The page multiplies by the provider's standard price and by 30. It runs in the browser. There is no account and no request is sent with your numbers.

The boxes start at 4,000 input tokens, 800 output tokens, and 10 tasks a day so the math is visible. That example is not a measured workload. Replace it with your own numbers.

  • This model has one standard input price and one standard output price on the OpenAI page. A separate long-context price is not listed on that row. Cached, batch, flex, and fast prices are not used.

Models in the list

21 models. The price is the standard per-million-token price on the provider page, not a reseller quote. Cached input, batch, flex, fast, and regional uplifts are left out on purpose, so a real invoice can be lower or higher.

Sources

Left out

  • OpenAI models that are on the pricing page but not in the dropdown, including gpt-4o, o3, and the pro variants.
  • Anthropic models marked limited availability or retired, and every cache-write price.
  • Google models other than Gemini 4 Argon and Gemini 3.8 Flash. The pricing page has more tiers, and the ones whose standard price was not clearly separated from batch and flex were not added.
  • xAI models other than grok-4.7 and grok-build-0.1. Cached-input prices on the xAI page are not used. DeepSeek and other providers are still left out, because their pricing pages were not copied into this tool on November 5, 2026.
  • Tool-call fees, search grounding, image tokens billed apart from the text price, tax, and seat licenses such as Claude Code or Codex plans.

FAQ

Is the 30-day figure a calendar month?

No. It is the daily cost times 30. A 31-day month would be one day more, and February would be less.

Do thinking tokens count?

For the two Google models, the provider says the output price includes thinking tokens. Add them to the output box. The OpenAI, Anthropic, and xAI rows on this page use the listed output price and do not add a separate thinking line, because those pricing tables do not show one for these standard rows.

Why is my provider missing?

Only prices copied from the provider pages above are included. A model that is not in the dropdown was left out rather than guessed. On November 5, 2026 that list gained gpt-6.1-terra, gpt-6-luna, grok-4.7, and grok-build-0.1. The prices already in the list matched the same pages.

Do I need an account?

No. The calculation stays in the browser. The numbers you type are not submitted.
