AWS Account Activity
The AWS Account Activity Page allows you to check any billable activity you have and see how much of the Free Tier you have used for the month. You account must be eligible for the Free Tier and you must stay within the limits of the Free Tier to run your Free Cloud Desktop without charges from Amazon Web Services.
AWS will prompt you to log in to your account if you are not already signed in. Click on the Account Activity Link to view your activity to date for the month, a link to your previous months and a link to your Billing Alerts, if any.
