How the calculation works
Input cost
Uncached input tokens ÷ 1,000,000 × input rate, plus cached input tokens ÷ 1,000,000 × cached rate.
Total cost
Input cost + output tokens ÷ 1,000,000 × output rate.

Understanding the result
Use rates from the provider and model you actually plan to use.
Cost per request is an average across the entered workload.
Important limitations
- Outputs are planning estimates and do not include every provider, accounting, financing, tax, legal, or operational factor.
- Invalid divisions are shown as not applicable rather than NaN or Infinity.
- Rates change and are intentionally editable; no hard-coded provider preset is claimed as current.
