Export the right columns
At minimum you need a model identifier plus input and output tokens. Optional cached tokens, request counts, and invoice cost columns make variance analysis possible.
Keep data local
The Usage CSV analyzer parses files in your browser. That keeps prompts and customer identifiers off CentsPerToken servers—still scrub secrets before sharing screenshots.
Read the variance carefully
List-price estimates will not match negotiated discounts, taxes, or image/audio lines. Use variance as a signal to investigate, not as accounting truth.
FAQ
Are token columns totals or per request?
CentsPerToken treats them as per-request figures and multiplies by the requests column (default 1).
