Everytime that I needed to take a look at where I stand up from the limits of an Azure subscription I do the same thing... Open my web browser, go to the management portal and browse between my storage accounts, cloud services, etc...
Here is a quick way in PowerShell to get that information without leaving your blue and white PowerShell console window. Use the -ExtendedDetails switch when calling the Get-AzureSubscription cmdlet.
To get the details of your current subscription
Get-AzureSubscription -Current -ExtendedDetails
or to get the details for all your subscriptions
Get-AzureSubscription -ExtendedDetails
This will give you this kind of informations
