How the estimate is calculated

Standard input tokens are billed at $10.00 per million, cached input at $1.00 per million, and output tokens at $50.00 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

  • Cached input represents a cache read; 5-minute and 1-hour cache writes cost $12.50 and $20 per million tokens.
  • Batch discounts, US-only inference surcharges, and third-party cloud endpoint premiums are excluded.
