How it works
The inverse of the cost calculator: fix the budget and read off the volume. Useful for setting a daily cap in your own code.
The formula
requests = budget / cost_per_request; per day over 30 daysWorked example
With the inputs the page opens on:
- budget: 500 USD
- model: claude-sonnet-5-5
- input tokens: 1500 tokens
- output tokens: 500 tokens
- cached share pct: 0%
gives
- requests: 62,500
- requests per day: 2,083
- total tokens: 125,000,000 tokens
- cost per request: $0.00800
