For API use, the price depends on the provider, model, token category and service mode—and your request’s input, output, caching and tool usage. Providers usually quote rates per million tokens, so estimate the whole request rather than treating a token as a fixed-dollar unit.
How to calculate the cost of an API request
Apply the selected model’s rate to each usage category separately, divide each product by one million when the rate is quoted per million tokens, then add any separately billed tools or services:
Estimated request cost = (input tokens × input rate + cached input tokens × cached input rate + output tokens × output rate) ÷ 1,000,000 + separately billed tool or service charges
Use the exact categories on the model’s rate card. Some providers distinguish cache reads from cache writes or charge for cache storage; some count reasoning tokens as output. Do not assume every input token is cached or that providers count images, audio, video and other modalities alike.

Example using GPT-6 Sol rates
OpenAI lists GPT-6 Sol at $2.00 per million standard input tokens, $0.20 per million cached input tokens and $10.00 per million output tokens for short context. A request with 10,000 standard input tokens and 1,000 output tokens, with no cached input or separately billed services, would cost $0.03 at those listed rates: ($2.00 × 10,000 + $10.00 × 1,000) ÷ 1,000,000. This is an illustration of the calculation, not a promised invoice. Check the current OpenAI API pricing page for the applicable model, context and service-mode row.

What can change your total
Input and output mix
Input and output rates can differ substantially. Calculate them separately; multiplying all conversation tokens by the input rate can understate or overstate the cost.

Reused prompt prefixes may qualify for a lower cached-input rate, but cache writes or storage can have separate charges. OpenAI describes automatic prompt caching for supported models on prompts longer than 1,024 tokens; that does not mean every token in every request is cached. Check the provider’s prompt caching documentation and rate card.
Processing mode
Some models offer discounted batch or lower-priority processing, while faster or priority modes can cost more. Eligibility and rates vary by model; compare the specific mode you will use, rather than assuming a discount applies to every request. OpenAI’s pricing documentation describes applicable service modes.
Context length and processing region
Long requests or regional endpoints may have different rates. OpenAI says GPT-6 Astra requests above 272K input tokens are charged at twice the input and cache rates and 1.5 times the output rate for the full request. Its pricing documentation also lists a 10% uplift for eligible regional-processing and FedRAMP endpoints. These conditions apply to the stated model and endpoint cases, not API requests generally; confirm the current terms on OpenAI API pricing.
Tools and other modalities
Images, audio, video, search grounding and other tools may use different billing rules or add charges. Gemini’s pricing page lists separate grounding and tool fees. Check whether retrieved content is included in token billing for the specific tool and endpoint.

Tokenization and reasoning
The same text can produce different token counts on different models, and models may generate different amounts of output or reasoning. A lower price per token therefore does not guarantee a lower cost for a completed task. OpenAI recommends testing representative work and comparing total usage and cost in its usage guidance.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Estimate and verify your own API cost
- Choose the exact setup. Record the provider, model, endpoint and service mode. Confirm that the rate card applies to your account and region.
- Collect usage by category. Use the request response or provider dashboard to find input, output, cached input and any other reported usage categories.
- Apply each rate separately. Multiply each category’s token count by its matching rate. Divide by 1,000,000 when the rate is per million tokens.
- Add non-token charges. Include separately billed tools, cache storage and modality fees where applicable.
- Check conditions on the rate. Verify context thresholds, regional processing, batch eligibility, account terms and effective dates.
- Test representative tasks. Compare the total cost to complete the same kind of work on each candidate model—not only the visible answer or input-token price.
- Reconcile the estimate. Compare your estimate with actual usage in the provider dashboard or request response. OpenAI documents both account-level dashboard review and request-level usage inspection in its usage guidance.
How to compare providers fairly
Use the same representative workload and compare the costs that actually apply to it. Include model capability for the task, input and output rates, cache reads and writes, context thresholds, service-mode eligibility, region and contract terms, and separately billed tools or modalities. A single input-price column cannot establish which provider will be cheapest for your work.
