AI Agent Cost Calculator

Agent Cost Calculator shows what running an agent will cost before you commit budget. Key features: • Compare 21 models from OpenAI, Anthropic, Google and xAI • Enter tokens per task and tasks per day • See cost per task, cost per day and a full 30-day bill • Uses official published model prices • No sign-up or login required • Instant results with no setup • Free to use for any agent or chatbot project. Rather than guessing at spend, you set your own workload and the calculator does the arithmetic. Change the model and the totals update immediately, so you can see exactly how much a cheaper or more capable option would change your monthly bill. This makes it easy to test assumptions about prompt length, response size and task volume before any code reaches production. Each result breaks the cost down so you can see where most of the money goes, whether that is input tokens, output tokens or sheer task volume. Developers, product managers, and founders building agent features can use it to plan budgets, justify model choices and set usage limits. Teams comparing vendors can run the same workload across providers in minutes. It is also useful for anyone trying to understand why a prototype that feels cheap in testing becomes expensive at scale.
