- Cost per call = input tokens × input price + output tokens × output price (prices per million tokens).
- Model usage = conversations × calls per conversation × cost per call.
- Total = model usage + other cost per conversation × conversations + fixed monthly cost.
- Cost per conversation = total ÷ conversations.

How it's calculated
- Cost per call = input tokens × input price + output tokens × output price (prices per million tokens).
- Model usage = conversations × calls per conversation × cost per call.
- Total = model usage + other cost per conversation × conversations + fixed monthly cost.
- Cost per conversation = total ÷ conversations.
- Assumes: Prices are the ones you enter: check your provider's current price list, including any discounts for cached input or batch requests.
- Assumes: Every call uses the average token counts you enter; in long conversations input grows with the history.
- Assumes: People's time to review conversations or take over from the agent is not included.

Good to know
What to consider
- Token prices are the ones you enter: check your provider's current price list, including cached-input and batch discounts.
- Input tokens usually dominate in long conversations, because each call resends the history.
Questions
About the AI Agent Cost Calculator
Where do I find my token counts?
Your provider's usage dashboard or API responses report input and output tokens per call. Take an average over a week of real conversations rather than a single test.
Can I share the calculator with my team or a client?
Yes. The Room keeps the calculator live: anyone with the link can change the numbers and see the result update, with the method and assumptions on the same page.
