This document describes COS billing modes, billable items, billing cycles, and prices.


Billing Mode

COS supports two billing methods: Pay-As-You-Go (postpaid) and Resource Packages (Prepaid). Details are as follows:
Billing Mode
Description
Pay-As-You-Go (postpaid)
This is the default billing mode of COS supported in all regions as described in Regions and Access Endpoints, where you use resources first and pay later. Fees of various billable items are calculated, settled, deducted, and billed daily. For more information, see Pay-As-You-Go.
Resource Packages (Prepaid)
COS offers discounted resource packs for various billing items, which are purchased in advance and used later. During settlement, the system will first deduct the usage of the resource pack, and any extra usage outside of the resource pack will be billed according to the actual usage. Resource packs are only applicable to public cloud regions and are not applicable to financial cloud regions. For more information, please see Prepaid Packages.


Billable Items

Note:
For details about the COS resource package usage period and deduction instructions, please refer to Resource Packages (Prepaid).
Starting from September 1, 2022, COS storage usage, request, and data retrieval fees are settled daily. For more information, see Daily Billing for COS Storage Usage, Request, and Data Retrieval.
