AI Coding Cost Calculator
This free AI coding cost calculator helps developers and engineering managers answer a simple question: how much will AI-assisted development actually cost? Instead of guessing based on per-token pricing pages, our calculator models the real-world token consumption patterns of AI coding agents — including context accumulation, iterative debugging, and tool-call overhead.
The calculator covers every major AI coding workflow: using ChatGPT or Claude as a chat assistant, Cursor or Windsurf as an in-editor copilot, Claude Code or Codex CLI as terminal agents, autonomous goal-mode sessions with Grok Build, and fully cloud-based agents like Devin. Each workflow tier has a different cost profile because of how aggressively it consumes context tokens.
Results compare costs across 110+ models from 22 providers including OpenAI (GPT-5.6, GPT-o4), Anthropic (Claude Opus, Sonnet, Haiku), Google (Gemini Pro, Flash), DeepSeek, Mistral, Qwen, and others. Use the calculator to set realistic sprint budgets, pick the most cost-effective model for your needs, or justify AI tooling investments to stakeholders.
