The Grouping functionality allows you to flexibly explore the financial costs in your AWS ecosystem. With this functionality you can group your costs by account, by region, by AWS service, by a specific tag, or by a user defined view. The flexibility of this functionality allows you to investigate cost spikes, report on cost centers, and fully understand your AWS bill.

In this guide you will be taken through exploring your EC2 usage costs by AWS account by AWS region. At the bottom of this guide is a reference to the different Stax Data page columns and the types of data that you can find in them.

  5. In the data so far there is a mixture of usage and credits which can make your numbers seem different to AWS. To explicitly show the cost of instance usage without the cost of credits select the "Group By" button and select "Kind".

  6. Select the "Filter" button and select "Kind" and then select "Usage" the costs that you are seeing are now the usage for the EC2 service broken down by account and by region.
