COS is billed at pay-as-you-go rates by default for all regions. Users are charged according to their actual storage usage, requests, traffic, and other billable items on a daily or monthly basis.
COS is billed on demand. For detailed pricing, see Product Pricing.
The billable items of COS and their calculation formulas are as follows:
|Billable Item||Description||Calculation Formula|
|Storage usage||Calculated based on the storage used at a unit price that varies by storage class|
|Requests||Calculated based on the number of requests at a unit price that varies by storage class||Request fees = Unit price per 10,000 requests x Monthly accumulated number of requests/10,000|
|Data retrievals||Calculated based on the volume of data retrieved at a unit price that varies by storage class. This billable item applies when data in STANDARD_IA and ARCHIVE storage classes is downloaded||Data retrieval fees = Unit price per GB x Monthly amount of data retrieved|
|Traffic||Calculated based on the public network downstream traffic, CDN origin-pull traffic, cross-region replication traffic, and global acceleration traffic at a unit price that varies by traffic type||Traffic fees = Unit price per GB x Daily accumulated traffic|
|Management feature fees||Fees generated by management features that you enabled and used, including inventory, extraction, batch operation, and object tagging||Inventory fees = Number of objects listed/One million x Unit price|
|COS extraction fees = Unit price per GB x Daily accumulated extraction traffic|
|Batch operation fees include job fees and object operation fees.
|Object tagging fees = Number of tags/10,000 x Unit price|
