⌁ How the estimate works

Monthly cost combines model tokens, tools, RAG, observability, human review and retry behavior from your editable assumptions.

monthly = model + tools + RAG + observability + human review + retries

? FAQ

Why can an invoice differ? Contracts, taxes, regional pricing, tool metering and usage behavior can change the final bill.

Count the tokens that repeat

Stable prompt instructions, tool definitions and retrieved context can dominate input volume. Measure them per step and make cache treatment an explicit assumption rather than an automatic discount.

Frequently asked questions

Does API list pricing equal my monthly cost?

No. List pricing is one input. Your bill can also reflect output length, cache behavior, retries, tool calls, storage, regional or contract terms, taxes and provider-specific metering.

Why estimate cost per successful task?

Requests that fail, retry, or need manual recovery still consume resources. Cost per successful task connects technical usage to the outcome your product actually delivers.

Can I use custom pricing?

Yes. Select Custom rates in the calculator and enter your own input and output price per million tokens. This is useful for negotiated or provider-specific terms.
