 For billing purposes, {% data variables.product.prodname_codespaces %} storage is counted in GB-months. This is a cumulative measure of the total storage each codespace consumes from creation to deletion, plus the storage for prebuilds.

+### Where did my monthly storage go?
+
+Deleting codespaces you're not using will avoid using up the free storage included in your personal account unnecessarily. However, if you have set up prebuild configurations, your included storage may continue to diminish during your monthly billing cycle. 
+
+Although prebuilds are not listed on the "Your codespaces" page, prebuilds created for a repository consume storage even if you do not currently have any codespaces for that repository. To avoid this, you can delete the prebuilds configurations you set up. For more information, see "[AUTOTITLE](/codespaces/prebuilding-your-codespaces/about-github-codespaces-prebuilds)" and "[AUTOTITLE](/codespaces/prebuilding-your-codespaces/managing-prebuilds#deleting-a-prebuild-configuration)."

 ## Understanding your {% data variables.product.prodname_codespaces %} usage
 
 You can check the cumulative {% data variables.product.prodname_github_codespaces %} usage for your current monthly billing cycle in your {% data variables.product.prodname_dotcom %} settings. For more information, see "[AUTOTITLE](/billing/managing-billing-for-github-codespaces/viewing-your-github-codespaces-usage)."
