Microsoft’s Agent Usage Estimator tool was launched in preview in June 2025. It’s now out of preview and works in largely the same way – you answer some questions about your use of internal or external Agents and you’re given a breakdown of your likely Copilot Credit consumption. Now, however, as well as seeing the results in the tool, you can download a PDF of the estimate too.
