Notes

  1. The Global-Bucket-Hrs and Global-Bucket-Hrs-FreeTier usage types apply to general purpose buckets in commercial AWS Regions and AWS GovCloud (US).

  2. If you terminate a transfer before completion, the amount of data that is transferred might exceed the amount of data that your application receives. This discrepancy can occur because a transfer termination request cannot be executed instantaneously, and some amount of data might be in transit, pending execution of the termination request. This data in transit is billed as data transferred "out."

  3. When objects that are archived to the S3 Glacier Instant Retrieval, S3 Glacier Flexible Retrieval, or S3 Glacier Deep Archive storage class are deleted, overwritten, or transitioned to a different storage class before the minimum storage commitment has passed, which is 90 days for S3 Glacier Instant Retrieval and S3 Glacier Flexible Retrieval, or 180 days for S3 Glacier Deep Archive, there is a prorated charge per gigabyte for the remaining days.

  4. For objects that are in S3 Standard-IA or S3 One Zone-IA storage, when they are deleted, overwritten, or transitioned to a different storage class before 30 days, there is a prorated charge per gigabyte for the remaining days.

  5. For small objects (smaller than 128 KB) that are in S3 Standard-IA or S3 One Zone-IA storage, when they are deleted, overwritten, or transitioned to a different storage class before 30 days, there is a prorated charge per gigabyte for the remaining days.

  6. There is no minimum billable object size for objects in the S3 Intelligent-Tiering storage class. Objects that are smaller than 128 KB are not monitored or eligible for auto-tiering. Smaller objects are always stored in the S3 Intelligent-Tiering Frequent Access tier.

  7. When you initiate a CreateMultipartUpload, UploadPart, or UploadPartCopy request to either the S3 Glacier Flexible Retrieval or S3 Glacier Deep Archive storage classes, requests are billed at S3 Standard request rates until you complete the multipart upload. After the upload is completed, the single CompleteMultipartUpload request is billed at the PUT rate for the destination S3 Glacier storage. In-progress multipart upload parts for a PUT to the S3 Glacier Flexible Retrieval storage class are billed as S3 Glacier Flexible Retrieval Staging Storage at S3 Standard storage rates until the upload is completed. Similarly, in-progress multipart upload parts for a PUT to the S3 Glacier Deep Archive storage class are billed as S3 Glacier Deep Archive Staging Storage at S3 Standard storage rates until the upload is completed.

  8. S3 Express One Zone applies a flat per-request charge for request sizes up to 512 KB. An additional per GB charge is applied for PUT requests and GET requests for the portion of request greater than 512 KB.

  9. For information about supported features for S3 Express One Zone storage class, see Amazon S3 features not supported by directory buckets: .

  10. Usage types with units that are billed in GB are calculated in bytes in the usage reports.

  11. A GB-Month is derived by taking the total number of GB-hours, aggregating these over the course of a month, and then dividing by the number of hours in that month. To learn more see, Frequently Asked Questions: How will I be charged and billed for my use of Amazon S3?

Note

In general, S3 bucket owners are billed for requests with HTTP 200 OK successful responses and HTTP 4XX client error responses. Bucket owners aren't billed for HTTP 5XX server error responses, such as HTTP 503 Slow Down errors. For more information on S3 error codes under HTTP 3XX and 4XX status codes that aren't billed, see Billing for Amazon S3 error responses. For more information about billing charges if your bucket is configured as a Requester Pays bucket, see How Requester Pays charges work.

Tracking Operations in Your Usage Reports

Operations describe the action taken on your AWS object or bucket by the specified usage type. Operations are indicated by self-explanatory codes, such as PutObject or ListBucket. To see which actions on your bucket generated a specific type of usage, use these codes. When you create a usage report, you can choose to include All Operations, or a specific operation, for example, GetObject, to report on.
