Cost at different volumes
Each row keeps the same token assumptions.
| Total requests per day | Requests / month | Monthly | Annual |
|---|---|---|---|
| 100 | 3.0K | $6.60 | $80.30 |

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.

How Grok API text pricing works
The estimate prices one model call as input tokens multiplied by the input rate, plus output tokens multiplied by the output rate. Include the full average input sent on each call, such as system instructions, resent chat history, or retrieved passages. The request count and token averages are values you supply.
The 200,000-token tier applies to the full request
xAI’s global rate card sets a higher input and output rate when a request contains 200,000 or more input tokens. At exactly 200,000, the higher rates apply to every input and output token in that call, not only the tokens above the threshold.
This page uses xAI’s standard uncached Global API rates. Cached input discounts, model-specific Batch prices, optional Priority Processing, U.S. regional multipliers, separately billed tool and search charges, embeddings, hosting, negotiated rates, credits, and multimodal usage are not included. Grok served through Azure, Oracle, Vertex, or another cloud host is also outside the estimate.
xAI bills reasoning tokens at the full completion rate. Include them in the output-token average you enter. The calculator does not estimate hidden reasoning-token counts.
