Planning estimate in USD, not an invoice or subscription quote. Standard API token rates; 30 days per month (22 workdays for coding). Use the additional reasoning-token control for billed thinking that is not replayed in conversation history; avoid double-counting it in visible output. Tool calls, search, images/audio, cache storage, taxes, regional surcharges and negotiated discounts are excluded. Retries mean extra full-cost attempts; actual failed-request billing varies. Compare low and high workload assumptions.
