AI Agent & Workflow Pricing Calculator
Price autonomous agents that loop, call tools, and consume 5–20× more tokens than a single chat turn.
Agents are the most expensive AI product to price. A single user task can fan out into 10–30 LLM calls, each with growing context. Naive 'per-task' pricing dies on the first complex run. Calcaas lets you model average tool calls, context growth, and per-step model choice.
Common pricing models
Per-task / per-run
Charge per completed agent run with a generous token budget headroom.
Compute-credit
Credits map to underlying token spend; complex tasks burn more.
Seat + included runs
Flat seat fee with an included run cap; overage bills per run.
Cost components to model
Planner LLM tokens
High-reasoning model for the planner step — usually the priciest.
Worker LLM tokens
Cheaper model for tool calls and intermediate steps.
Tool API costs
Each tool call may hit a paid API (search, browser, code execution).
Context bloat
Tool outputs accumulate in the loop — model the worst case, not the best.
Recommended models
| Provider | Model | Why |
|---|---|---|
| Anthropic | claude-opus-4-7 | Top-tier planner for hard agent tasks. |
| OpenAI | gpt-4o-mini | Cheap worker model for tool-call steps. |
| gemini-2.5-flash | Fast, cheap fallback for non-reasoning steps. |
Example scenario
Setup
$0.50 per task: 1 Opus planner call (4K in / 1K out) + 8 Haiku worker calls (2K in / 500 out each).
Watch out for
P95 task complexity — average is fine, but the long-tail user runs 30 steps and burns your margin.
