Detailed Billing Reports


The Detailed Billing Report feature is unavailable for new customers as of 07/08/2019.

Detailed Billing Reports (DBR) contain similar information as Amazon CUR regarding your charges, but calculates the individual line items differently. If you've signed up for both the DBR and Amazon CUR, the line items will not match. However, when the reports are finalized at the end of the month, the total cost will align.

Amazon stores the DBR in Amazon S3 as csv files, using the following naming convention:

Amazon recreates the DBR multiple times a day, overwriting the report. When Amazon overwrites a report, the line items might be in a different order than they were in the previous report. A final report is created at the end of the month. For the following month, Amazon creates a new report file instead of overwriting the final report from the previous month. Reports for previous months remain in your S3 bucket until you delete them.

For information on how to migrate your DBR to Amazon CUR, see Migrating from Detailed Billing Reports to Cost and Usage Reports.
