Detailed Billing Reports - AWS Data Exports

Detailed Billing Reports


The Detailed Billing Reports feature is unavailable for new customers as of July 8, 2019.

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

AWS stores DBR in Amazon S3 as CSV files using the following naming convention:

AWS recreates Detailed Billing Reports (DBR) multiple times a day, overwriting the reports. When AWS overwrites reports, line items might be in a different order than they were in previous reports. A final report is created at the end of the month. For the next month, AWS 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.
