Use the rates as an explicit assumption
The rates are stored separately from the calculator in a dated research file. They are never silently applied to your worksheet. If a model, context tier or price changes, recheck the official page and enter the new values. Snapshots older than 30 days are marked for review in the browser.
What the simple estimate excludes
Cached-token writes and hits, long-context uplifts, batch discounts, regional processing, search/tool calls, audio, images, storage, tax and negotiated terms may have separate rates. Include them as additional costs when relevant. Provider quotas and access are not guaranteed by a published price.
