FAQ

Questions about llm token cost calculator

Multiply the input tokens by the input price per million tokens, add the output tokens times the output price, and divide by one million. The calculator does that for the model you pick.

From the OpenRouter model list, read through looot on the date shown under the calculator. Prices change, so check that date before you quote a number.

Yes. It runs in your browser, needs no account and makes no API call. There is no limit on how often you use it.

Most providers price output higher because the model generates it one token at a time. The calculator shows both prices so you can see which side drives your bill.

It depends on the model's tokenizer and the language. Count real prompts with the model's own tokenizer when the number matters, then type that count here.

Batch variants appear as their own rows when the model list has them. Cached input and per-search fees are not in this list, so the calculator leaves them out.

Copy the prompt above. Your agent runs the OpenRouter model list endpoint through looot and works out the same numbers with today's prices.

Switch the model and the numbers update at once. For a table of many models, the model price page on looot lists every row of the same snapshot.
