How the estimate works

The calculator prices your token counts at the bundled per-token rates: cache reads at 0.1× input, cache writes at 1.25× (5-minute) or 2× (1-hour), and a premium tier above 200K/272K context. It is an estimate — your real cost depends on your exact cache-hit pattern.

Common questions

Is this calculator accurate?
It uses the same published per-token rates JP prices real usage at, so it is close — but it cannot know your exact cache reuse, which is the biggest swing factor.
