Agent calculator
AI Agent Cost Calculator
Estimate the cost per completed AI agent task. Model loops, retries, repeated context, dynamic tool output, and generated responses.
Estimate agent cost per task
Why agents need a separate calculator
An agent task can trigger many model calls. The core estimate istasks * calls per task * retry multiplier * token cost.
- Repeated context can dominate input cost if it is sent on every step.
- Retries and tool outputs make costs grow faster than simple chat usage.
- Cost per completed task is usually more useful than cost per prompt.
Model every hidden call
Planning, tool use, critique, and final response steps can each trigger model calls.
Add failure overhead
Retries, validation failures, and tool errors can increase spend above clean-path estimates.
Track cost per task
Use task-level cost before pricing agent workflows or setting usage limits.
FAQ
Why are AI agents more expensive than simple chat?
Agents often make multiple model calls per task, pass repeated context at each step, process tool output, and retry failed steps. That multiplies token usage.
What is the best unit for agent cost?
Cost per completed task is usually more useful than cost per request because one user-visible task can contain many hidden model calls.
