Deleted ALL Resource Groups but still seeing continuous charges in Cost Analysis under the Subscription

Hello @Arvind Kumar

Deleting the resource groups does not immediately remove their names or historical charges from Azure Cost Analysis. Cost Management retains cost and usage records for resources and resource groups that have already been deleted, so seeing a deleted resource-group name in Cost Analysis does not necessarily mean that the resource group still exists or is generating new usage.

There can also be a delay between when usage occurs and when it appears in Cost Management. EA/MCA usage is typically available within 8–24 hours, while Pay-As-You-Go usage can take up to 72 hours. As a result, charges appearing after deletion may reflect usage incurred before you deleted the resources.

Since you deleted the resource groups 4–5 days ago, check whether the cost is still ongoing rather than just looking at the accumulated monthly total.

In Cost Management > Cost analysis, change the granularity to Daily, then group/filter by Resource, Resource type, or Meter. Look at the usage dates of the newest charge rather than the resource-group name.

This is particularly important for your case because these resource groups contained Azure Databricks workspaces. When you delete a Databricks workspace, most compute resources (VMs and disks) are cleaned up, but some resources can remain. For Unity Catalog-enabled workspaces, the default workspace catalog and associated storage/access connector can also remain unless you force-delete the workspace.

So check the latest cost line item and identify its Resource name, Resource type, Meter, Usage date, and Charge amount.

If the newest usage date is from before the resource groups were deleted, you're most likely seeing delayed/historical billing data.

If the usage dates are after deletion and continue increasing each day, then something is still producing billable usage. In that case, check the subscription's Resources view and enable Show hidden types, because subscriptions can contain active hidden resources even when the normal resource view appears empty.

If no resources, including hidden resources, remain but new Databricks-related usage continues several days after deletion, open an Azure Billing support request and provide the Cost Details line items. I specifically recommend a support request when you can't identify usage or charges.

If possible, please share a screenshot of Cost Analysis grouped by Resource or Meter with Daily granularity for the period beginning one day before deletion through today. Please hide your subscription ID and other identifying information. That should tell us whether these are delayed historical charges or new post-deletion consumption.
