Codex vs Copilot
Codex vs Copilot Cost Calculator
Codex-style agent work and Copilot-style coding assistance can both save time, but they may create cost in different places.
Use this page to compare agentic task budgets against GitHub-native coding assistance.
Cost drivers to model
- Repository context, selected files, logs, and documentation included in the task.
- Generated code, tests, explanations, review comments, and follow-up edits.
- Retry rate, failed runs, cache writes, cached input, and monthly repetition.
- Subscription price, included credits, API rates, or any internal team budget.
Recommended calculation flow

FAQ
Is this exact provider pricing?
No. The calculator is designed for planning. Keep the assumptions editable and verify current provider pricing before making billing decisions.
What is the most important input?
For coding agents, repeated repository context is often the hidden driver. A small patch can still involve a large amount of input context and several retries.
