# Billing and usage reporting for Amazon S3
<a name="BucketBilling"></a>

When using Amazon S3, you don't have to pay any upfront fees or commit to how much content you'll store. Like other AWS services, you pay as you go and pay only for what you use.

AWS provides the following reports for Amazon S3:
+ **Billing reports** – Multiple reports that provide high-level views of all of the activity for the AWS services that you're using, including Amazon S3. AWS always bills the owner of the S3 bucket for Amazon S3 fees, unless the bucket was created as a Requester Pays bucket. For more information about Requester Pays, see [Using Requester Pays general purpose buckets for storage transfers and usage](RequesterPaysBuckets.md). For more information about billing reports, see [AWS Billing reports for Amazon S3](aws-billing-reports.md).
+ **Usage report** – 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 [AWS usage reports for Amazon S3](aws-usage-report.md).
