When you store objects in Object Storage Service (OSS), you are charged storage fees based on the storage classes, sizes, and storage durations of the objects.

Note This topic describes the billable items and billing methods of OSS. For more information about OSS pricing, see Object Storage Service pricing.

Billable items
