If you are using an Azure free account, your free services and quantities expire at the end of 12 months. You can check when your free services expire:
- Sign in to the Azure portal.
- In the left navigation area, select All services.
- Select Subscriptions.
- Select the subscription that was created when you signed up for free account.
- Scroll down to find free services grid. Select the tooltip located on the top left of the grid.
Microsoft will send you an email notifying you when it's time to upgrade.
Once your free services and quantities expire, you're charged pay-as-you-go rates for any services you're using. You can use the Azure portal to delete the resources for the services that you don't use. If you don’t intend to use any Azure service, you can cancel your subscription.
