Cost at different volumes
Each row keeps the same token assumptions.
| Monthly request volume | API requests / month | Monthly | Annual |
|---|---|---|---|
| 1.0K | 1.0K | $3.00 | $36.50 |
| 10.0K | 10.0K | $30.00 | $365.00 |
| 100.0K | 100.0K | $300.00 | $3,650.00 |
| 1.0M | 1.0M | $3,000.00 | $36,500.00 |
Monthly estimates use 30 days. Annual estimates use 365 days.
Estimate covers public standard text input and output rates only. If your provider bills reasoning or thinking tokens as output, include them in your output-token estimate; this calculator does not infer them. It excludes cached-token pricing, batch discounts, external tools and search, embeddings, vector stores, hosting and infrastructure, negotiated discounts, free-tier credits, and image, audio, video, or voice usage.

A request-based estimate
The request field is the full monthly count, not users multiplied by requests per user. The estimate prices one average text request at the selected model’s public direct API rate, then applies your monthly volume.
