Workload cost calculator
Share of input tokens served from cache. Applied only to models with a cache meter.
Rows with a rate that changes by time of day, promo window or service tier are priced for this scenario instead of their flat listed rate; a brand-colored label under the model name names which one applies. Context size for band-priced rows uses the input-token count below.
Picking a specific hour also previews time-of-day rates that are scheduled but have not started billing yet; those rows are labelled · preview with their start instant. Now only ever shows rates that are billable at this moment.
What this lane charges right now

Where this workload's cost goes
60M input tokens (90% cache hit) and 210K output tokens, at the resolved rate above.
$12.00 + $5.40 + $2.10 = $19.50
How much to trust these numbers
Released September 28, 2026. Anthropic's October 7 update cuts cache reads to $0.10/M; input/output remain $2/$10 per M. Its Batch API halves input/output and the cache-read multiplier stacks, making Batch cache reads $0.05/M.
Anthropic's October 7 release note and current Claude Sonnet 5.5 pricing page, captured 2026-10-08, confirm $2/M input, $0.10/M cache reads (down from $0.20/M), and $10/M output. Cache writes remain $2.50/M for 5 minutes and $4/M for one hour, outside this schema. The Batch API halves input and output; the 0.05x cache-read multiplier stacks with Batch to yield $1/$0.05/$5 per M.
