How the calculation works

Standard input tokens are multiplied by the model's input price. Eligible cached tokens use the cached-input price, and output tokens use the output price. Request cost is then multiplied by daily requests and days per month.

monthly cost = cost per request × requests per day × days per month

Prices are loaded from the same local dataset used by the model pricing pages. Review the source link and verification date shown beside every result.

For GPT-5.6 models, V1 quotes Standard short-context pricing through 272,000 input tokens per request. Larger requests use OpenAI long-context pricing and are not quoted at the short-context rate.
