Hi,
In Azure portal, please navigate to your Subscription. On left, expand Cost Management and then click on Cost analysis blade. On right, at top, click on View -- Cost by resource
After several seconds you should see a list of resources with their accumulated charges for this month, sorted by highest to lowest. If you would like to change to show a different date range, you may click the date filter at the top and change it.
There are many different views of cost data and ways to filter/sort it. Please see article below to get started:
