About & methodology

LLM Cost Calculator is an independent tool for developers budgeting LLM features. It is not affiliated with any model provider.

Where prices come from

Every price is taken from the provider's official pricing page or documentation and stored with its source URL and the date it was checked. We use standard list prices: no enterprise discounts, regional surcharges or priority tiers.

Limits

Token counts differ between tokenizers, so the same text can be more tokens on one model than another. The token counter documents which counts are exact and which ratios are assumed. Estimates are for planning; your invoice is the source of truth.

Guides

The use-case guides rank models with the same cost engine as the calculator. Each one lists its workload assumptions; none of them measures model quality.
