Methodology
Each token component is multiplied by its source-linked per-million-token price. Cached tokens use a cache-read price only when that endpoint publishes one; otherwise they retain the normal input rate.

Estimated Cost: $0.50
| Component | Tokens | Rate / 1M | Estimated cost |
|---|---|---|---|
| Uncached input | 1,000,000 | $0.10 | $0.10 |
| Cached input | 0 | $0.010 | $0.0000 |
| Output | 1,000,000 | $0.40 | $0.40 |
| Total | $0.50 | ||
Estimates exclude retries, minimum charges, taxes, tiered pricing, and price changes after the observation date.
Inputs
What the Calculation Needs
| Input | How it is used |
|---|---|
| Model and provider | The exact endpoint whose rates should be used. |
| Input tokens | All billed prompt and context tokens in the workload. |
| Cached input | The input subset eligible for a published cache-read rate. |
| Output tokens | All billed completion or reasoning output tokens. |
How to Interpret the Result
Use the result as a list-price scenario, then add retry, tool-call, storage, tax, and tier effects that apply to your contract.
Boundaries
What the Result Does Not Prove
- Price minima are not blended rates across providers.
- Unsupported currencies are not converted.
- Price changes after the observation timestamp are outside the estimate.
Catalog values retain their source and freshness on the linked model, provider, benchmark, or comparison page. Editable scenario assumptions are not Model Markets measurements.

Questions
LLM Cost Calculator FAQs
What does the LLM Cost Calculator calculate?+
Price one explicit token workload against an exact published provider endpoint. It returns a component-level cost breakdown using the selected endpoint's published currency and token units.
Does the LLM Cost Calculator use current model data?+
Where the calculation needs model facts, it uses the current Model Markets catalog snapshot updated 2026-09-02. User-entered assumptions remain clearly editable, and unsupported values stay unknown rather than being inferred.
What should I verify before using the LLM Cost Calculator result?+
Price minima are not blended rates across providers. Unsupported currencies are not converted. Price changes after the observation timestamp are outside the estimate. Open the linked canonical records and primary sources before making a production or purchasing decision.
