How the calculator works

Cost per request is input tokens × the input price, plus output tokens × the output price, divided by a million. We multiply by your monthly requests. Batch applies each provider's own batch discount where it offers one; caching bills half your input at the provider's cache-read price, and models with no published cache-read price are billed at the full input rate.

Prices are list prices from each provider's pricing page, checked on 13 Nov 2026. They exclude tax, volume discounts and cache-write fees.

How many tokens is a typical request?
A short chat message with a little history is around 1,000–2,000 input tokens. A request with a few pages of documents can be 10,000–30,000.
Why does output matter so much?
Output tokens cost several times more than input on most models, so long answers dominate the bill even when prompts are much longer.
Can I share an estimate?
Yes. Copy link saves your inputs in the URL, so anyone opening it sees the same ranking.
