AWS Cost Categories now support retroactive rules application

AWS Cost Categories now support retroactive application of cost category rules. Previously, while creating a cost category, the rules applied from the start of current month. Similarly, while editing a cost category rule, the changes applied from the start of current month. With this launch, while creating a cost category, you can apply cost category rules starting any month from the previous 12 months. Similarly, while editing a cost category, you can apply cost category rules starting any month from the previous 12 months. These changes will also be reflected in AWS Cost Explorer.

AWS Cost Categories is a feature within the AWS Cost Management product suite that enables you to group cost and usage information into meaningful categories based on your needs. You can create custom categories and map your cost and usage information into these categories based on the rules defined by you using various dimensions such as account, tag, service, charge type, and even other cost categories.

This feature is available in all regions. There is no additional cost for using this feature. To get started with retroactively applying your cost category rules, visit the AWS Cost Categories page and user guide.
