What the Prompt Cache Savings Calculator Checks

Repeated request count

Savings are calculated across a batch of repeated calls, not a single isolated prompt.
Cached token boundary

Cached tokens are capped at the total input token count to avoid impossible scenarios.
Write versus read rates

The calculator separates first cache write cost from later cache read cost.
Output token cost

Generated output is included in both cached and uncached totals.
Scenario clarity

The result shows absolute savings and savings rate so tiny wins are easy to spot.
