Description
The AI Agent Cost Calculator is a free, web-based tool designed to help individuals and teams understand and manage the operational costs of their AI agents, chatbots, and RAG (Retrieval Augmented Generation) applications. It allows users to estimate monthly LLM token costs across a selection of 79 different large language models (LLMs), with prices verified daily from OpenRouter and corrected against official provider pages.

The calculator addresses a common challenge for AI developers and users: the often-unexpectedly high costs associated with AI agents. Unlike simple chatbot interactions, AI agents typically operate in multiple steps, with each step potentially resending the entire conversation history as input. This iterative process can rapidly increase token consumption and, consequently, costs. The tool accounts for this by allowing users to specify parameters such as steps per task, input and output tokens per step, and tasks per day.
Key capabilities include comparing models side-by-side, understanding the impact of prompt caching (where repeated input tokens are billed at a lower cache-read price), and exploring various workload presets like customer support chatbots, RAG Q&A systems, coding agents, and research agents. Users can input their own token counts or use predefined scenarios to quickly see cost estimates. The results are sorted by monthly cost, making it easy to identify the most economical options for a given workload.
Beyond basic cost estimation, the platform provides educational resources through its "AI Agent Cost Guides." These guides offer plain-English explanations of concepts like prompt caching, strategies for reducing LLM token costs, and comparisons of the cheapest LLMs for AI agents. The site also features an LLM pricing table for all 79 models and a log of recent price changes, ensuring transparency and up-to-date information.
For those new to AI agent cost management, the calculator offers a "Find my setup" AI assistant that helps fill in initial parameters based on a project description. Additionally, a free MCP server connector is available for users of Claude or Cursor, allowing their AI agents to check costs directly. The tool is a small, independent project, with AI assisting in its development and content creation, and it operates without requiring user sign-up or storing personal data entered into the calculator.
