AI Agent Cost Estimator

Estimate monthly AI agent cost from model usage, tools, orchestration, and support overhead.

AI Agent Configuration

Configure your AI agent stack to estimate monthly costs.

Human Support Hours / Week

Support Hourly Cost ($)

How It Works

Model Cost = (Input Tokens x Input Price + Output Tokens x Output Price) x Monthly Queries

Tool Call Overhead = Additional tokens from tool calls (approx 30% per call of base query cost)

Total Monthly = Model + Tool Calls + Orchestration + Vector DB + External APIs + Human Support

Cost per Query = Total Monthly Cost / Monthly Query Volume

Understanding AI Agent Cost Structures

AI agents are more expensive than simple API calls because they make multiple LLM calls per interaction (tool use, reasoning loops, RAG retrieval). A single user query might trigger 3-10 LLM calls internally. Understanding each cost component helps you optimize spending and choose the right model for each task.

Model Selection Matters Enormously

Current standard API input prices range from $0.20 per million tokens for GPT-5.6 Luna to $10 for Claude Fable 5. For many agent tasks (routing, classification, simple extraction), smaller models perform nearly as well. Use expensive models only where quality demands it, and route simpler subtasks to cheaper models.

Hidden Costs: Orchestration and Human Oversight

Platforms like LangChain Cloud, CrewAI, or custom orchestration layers add fixed monthly costs. Vector databases for RAG (Pinecone, Weaviate, Qdrant) scale with data volume. And the most overlooked cost is human oversight: reviewing agent outputs, handling failures, and maintaining prompt chains. Budget 10-20 hours per week minimum for production agents.
