I want to know how Amazon Elastic Block Store (Amazon EBS) volumes that are associated with my account are charged on my bill.

Resolution

You're billed for Amazon EBS volumes by the gigabyte-month (GB-month). The GB-month is a measure of how many gigabytes of EBS storage that you provision to your account. It's also a measure of how long you provision the EBS storage to your account. A GB-month is 1 GB of storage for one month.

In a 30-day month, you're billed for one GB-month in the following scenarios:

  • You provision a 30-GB volume for 24 hours.
  • You provision a 1-GB volume for 720 hours (the number of hours in 30 days).

You're billed for the total amount of storage that you provision to your account, even if you don't use the storage. For example, if you provision a 100-GB EBS volume for a month, then you're billed for 100 GB-month of EBS storage. Even if you store only 10 GB of data on that volume, you're billed for 100 GB-month of EBS storage.

For more information and pricing examples, see Amazon EBS pricing.

To minimize the amount that you're billed for Amazon EBS storage, complete the following steps:

  • Create snapshots of any volumes that you're not actively using.
  • Delete snapshots that you no longer need.
  • Audit your EBS volumes to see if you're using most of the storage in the volume. If you're not using most of your volume's storage, then migrate your data to smaller EBS volumes.
