Input
Enter token totals to calculate the estimate.
Estimates depend on actual tokenization, selected model, cache behavior, and current pricing data. For Anthropic cache writes, generic cache-write tokens use the 5-minute cache-write reference unless duration buckets are available.
What counts as output?
Output tokens are what the model generates, including code, explanations, structured JSON, or streamed assistant text.
What about cache?
Cache reads and writes are usually visible in provider or proxy usage logs. Enter them separately when your workflow reuses large contexts.
Start with a small test balance.
Run one known workflow, compare the calculator against real usage logs, then scale only after the estimate matches your setup.
