Verify AMI charges on your bill

To ensure that you're not incurring unplanned costs, you can verify that the billing information for an instance in your Amazon Cost and Usage Report (CUR) matches the billing information that's associated with the AMI that you used to launch the instance.

To verify the billing information, find the instance ID in your CUR and check the corresponding value in the lineitem/Operation column. That value should match the value for Usage operation that's associated with the AMI.

For example, the AMI ami-0123456789EXAMPLE has the following billing information:

If you launched an instance using this AMI, you can find the instance ID in your CUR, and check the corresponding value in the lineitem/Operation column. In this example, the value should be RunInstances:0010.
