S3 Storage Cost/Usage Report

The S3 Storage Cost/Usage report provides you with the storage and usage costs across all of your S3 buckets.  All costs in the report are extracted from your AWS Detailed Billing reports and aggregated over a user-defined time period.   The report will provide you with the cost of storing objects in your bucket, broken down by the different storage types, as well as the costs associated with using the S3 service.


No cost data will display when you first load your report. You must click the filter button to load results. If you do not choose any filter options, by default, the report will show you your storage costs over the last 14 days for whichever account you are currently viewing.

Use the Start and End date to display a custom data range. NOTE: You will only have data available from the month you first enabled the Detailed Billing reports within AWS.

Cost Type allows you to display the costs in the report using Unblended, Blended, or List Price.

Finally, select which account you would like to view cost data for. If you are viewing this report within a consolidated billing master payer account, you will have the ability to view the report for any of your sub-accounts. There is also an “All” option, allowing you to view the report across all of your linked accounts.

Once you have chosen which data you would like to see, click the Filter button.


Once you filter the report, CloudCheckr goes out to your AWS Detailed Billing report and retrieves the relevant S3 storage and usage cost data for each bucket over whichever date range you’ve selected. The report will then display a cost chart, showing the daily costs for each storage and usage type, as well as a cost breakdown by bucket below.

You can hover over any day in the chart and it will provide you with a list of each storage and usage type cost for that day. You can also manipulate the chart by selecting or unselecting any of the cost types in the legend below the chart.

The Totals section provides a rollup of all the costs associated with each S3 storage and usage type:

  • Standard Storage – the cost for objects stored using Standard storage.
  • Glacier Storage – the cost for objects stored in S3 Glacier.
  • Reduced Redundancy Storage – the cost for objects stored using Reduced Redundancy storage.

The Cost by Bucket section allows you to get a detailed breakdown of the storage costs associated with each bucket within S3.

For each bucket you will see its total cost, as well as its standard storage, glacier storage, and reduced redundancy storage costs.
