Why am I being charged for Amazon EBS when all my instances are stopped?

Resolution

You are charged for Amazon EBS storage for the amount of storage provisioned to your account, measured in "gigabyte-months." Amazon EC2 instances accrue charges only while they're running. However, EBS volumes attached to instances continue to retain information and accrue charges, even when the instance is stopped. For more information about how Amazon EBS is billed, see Amazon EBS pricing.

Amazon EBS snapshots are billed at a lower rate than active EBS volumes are. You can minimize your Amazon EBS charges but retain the information stored in Amazon EBS for later use by creating a snapshot of the volume as a backup and then deleting the active volume. Later, when you need the information stored in the snapshot, you can replace the EBS volume using the snapshot for use with your infrastructure.

To stop Amazon EBS-related charges, delete EBS volumes and Amazon EBS snapshots that you don't need.

I've deleted snapshots of my EBS volume, and then I deleted the volume. Why aren't my data storage costs lower?
