# Using Amazon billing and usage reports
<a name="billing-usage-reporting"></a>

When using Amazon EFS, you pay only for the resources you use and there are no minimum fees or setup charges. Like other Amazon services, while pricing is quoted on a monthly basis, your usage is prorated by the hour, and you are billed for your average usage over a month.

Amazon provides the following reports for Amazon EFS:
+ **Billing reports** – Multiple reports that provide high-level views of all of the activity for the Amazon services that you're using, including Amazon EFS. Amazon always bills the owner of the EFS file system for Amazon EFS fees. For more information about billing reports, see [Amazon Billing reports for Amazon EFS](aws-billing-report.md). 
+ **Usage reports** – A summary of activity for a specific service, aggregated by hour, day, or month. You can choose which usage type and operation to include. You can also choose how the data is aggregated. For more information, see [Amazon usage reports for Amazon EFS](aws-usage-report.md).
