AI agent cost calculator

Agents multiply calls per task. Estimate the task once, then multiply by how often the task actually runs — the compounding is where agent budgets are won or lost.

How the estimate is computed

Token cost is arithmetic and identical for every provider: input tokens and output tokens are each priced per million tokens and summed. The per-run cost becomes a monthly projection by multiplying with runs per day and days.

monthly = (input tokens x input rate + output tokens x output rate) / 1,000,000 x runs per day x 30

What the estimate leaves out

Re-rate the calculation with your own token counts and the current per-million rates published in the model catalogue. Estimates exclude taxes, platform fees, cache rules, minimum purchases, failures and retries; verify a real bill against the provider's usage records.

FAQ

How is the AI agent cost calculator estimate computed?

Input tokens multiplied by the input rate plus output tokens multiplied by the output rate, divided by one million, then multiplied by runs per day and days. Every step is plain arithmetic you can reproduce.

What does the AI agent cost calculator estimate exclude?

Taxes, platform fees, cache-specific billing rules, minimum purchases, failed requests and retries. Verify a real bill against the provider usage records.

Where do the per-million rates come from?

Providers publish rates per million tokens; the Rynler model catalogue lists the current values. Rates change over time, so re-rate the calculation with current values before committing to a workload.
