How are charges for Amazon EBS volumes calculated on my bill?

2 minute read

I have Amazon Elastic Block Store (Amazon EBS) volumes associated with my account. How are they charged on my bill?


Amazon EBS volumes are billed by the gigabyte-month (GB-month). The GB-month is a measure of how many gigabytes of EBS storage are provisioned to your account. It is also a measure of how long the EBS storage is provisioned to your account.

In a 31-day month, you are billed for one GB-month in the following scenarios:

  • If you have provisioned a 31-GB volume for 24 hours.
  • If you have provisioned a 1-GB volume for 744 hours (the number of hours in 31 days).

You are billed for the total amount of storage provisioned to your account, even if the storage isn't used. For example, if you provision a 100-GB EBS volume for a month, you are billed for 100 GB-month of EBS storage. Even if you only store 1 GB of data on that volume, you are billed for 100 GB-month of EBS storage.

For more information, see Amazon EBS pricing.

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