How the estimate is calculated

Standard input tokens are billed at $1.50 per million, cached input at $0.15 per million, and output tokens at $9.00 per million.

monthly cost = 30 × requests/day × (input cost + cached input cost + output cost)

What this estimate excludes

Provider account tiers, regional taxes, tool calls, storage, fine-tuning, data transfer, and other product-specific charges are excluded unless explicitly represented in the calculator.

Pricing notes

  • Output pricing includes thinking tokens; this calculator uses the standard paid tier rather than Batch, Flex, or Priority pricing.
  • Context cache storage costs $1 per million cached tokens per hour and is not included.
