A Microsoft offering that enables tracking of cloud usage and expenditures for Azure and other cloud providers.
High charges can still appear even when nothing seems active because Azure can bill for resources that remain allocated or for usage that was already incurred in the billing period. Deleting or stopping visible workloads does not always remove every billable item.
Common supported reasons are:
- Resources may still exist and be generating charges Review the cost details to identify the exact resource or meter that produced the storage and networking charges.
- Unexpected charges should be investigated in Cost analysis
In the Azure portal:
- Go to Subscriptions.
- Select the affected subscription.
- Select Cost analysis.
- Use the Invoice details view to compare invoiced charges with usage.
- Filter by the invoice period and invoice number to see which items were billed.
- Review the invoice and usage CSV
If the subscription is a paid individual subscription and the files are available:
- In the Azure portal, search for Subscriptions.
- Select the subscription.
- Under Billing, select Invoices.
- Download the invoice and CSV usage file. The CSV shows charges by billing period and daily usage, which helps identify the storage or networking line items.
- Check for hidden resources
If visible resources were already deleted, hidden resources can still block full cleanup and continue to exist. In the Azure portal:
- Go to Subscriptions.
- Select the subscription.
- Select Resources.
- Select Manage view.
- Turn on Show hidden types.
- Review and delete any remaining resources. Deletion is destructive and can permanently remove data.
- Review audit logs and permissions if the charges are unrecognized For unexpected usage, the documented steps are to review the invoice, review invoiced charges in Cost analysis, find people responsible for the resource, analyze audit logs, and analyze permissions on the parent scope.
- Open a billing support request If the billed storage and networking items still do not make sense after checking Cost analysis and the usage file, create a support request so billing support can help identify the charge source.
