- Per run
- $0.0337
- Per month
- $506.25
Estimate what an AI agent costs to run. Agents loop through multiple steps and tool calls, so cost adds up quickly. Set the steps, tokens per step, and tool usage to see cost per run and per month.
How this is calculated
This calculator uses the agents formulas described in our methodology. All figures are estimates for planning; verify current pricing with each provider before relying on them.

Frequently asked questions
Why do agents cost more than a single call?+
Each step is a full LLM call that usually includes the growing context of previous steps, so a 5-step agent can cost several times a single request.
How do I reduce agent cost?+
Reduce steps, trim context passed between steps, use a cheaper model for routine steps, and cache stable context.
