1M input tokens

$5.00

Input-only example at the listed standard token price.

1M output tokens

$30.00

Output-only example at the listed standard token price.

Example 1M-token mix

$11.25

Defined as 750K input tokens plus 250K output tokens.

1M cached-input tokens

$0.50

Cached-input-only example using the listed cached price.

Usage assumptions

Estimate traffic and token usage for an average request.
Active seats, customers, or internal users.
Average AI calls per user each day.
Prompt, history, and retrieved context per request.
Generated answer length; SaaS founders should test long replies.
Reusable cached prompt or context tokens per request.
Use 30 for always-on products or fewer for batch jobs.

Estimated results

Run the calculator to see projected cost and usage volume.

Enter your usage details, then select Calculate estimate to see your projected cost.

Estimated cost = input usage cost + output usage cost + supported optional charges.
