The AWS Cost & Usage Report is a single location for accessing comprehensive information about your AWS costs and usage.The AWS Cost & Usage Report lists AWS usage for each service category used by an account and its IAM users in hourly or daily line items, as well as any tags that you have activated for cost allocation purposes. You can also customize the AWS Cost & Usage Report to aggregate your usage data to the daily or monthly level.
The AWS Cost & Usage Report contains the most granular set of AWS cost and usage data available, including additional metadata about AWS services, pricing, and reservations (e.g., Amazon EC2 Reserved Instances (RIs)).
AWS delivers the AWS Cost & Usage Report (in CSV format) to whichever Amazon Simple Storage Service (S3) bucket you specify, and updates the reports at least once per day. You can download any of the reports using the Amazon S3 console, or you can retrieve the reports programmatically using the Amazon S3 APIs. The AWS Cost & Usage Report can also be ingested directly into Amazon Redshift or uploaded to Amazon QuickSight.
The AWS Cost & Usage Report gives you the ability to delve deeply into your AWS cost and usage data, understand how you are using your AWS implementation, and identify opportunities for optimization. View the full data dictionary
