COS is billed in a pay-as-you-go manner. This document describes the pay-as-you-go billing details. This billing method is applicable to all regions where the COS service is provided. COS fees are charged for billable items such as storage capacity, requests, and traffic daily or monthly.
The billable items in COS and their billing formulas are as detailed below:
|Billable Item||Description||Billing Formula|
|Storage capacity fees||Calculated based on the storage capacity used at a unit price that varies by storage class||Storage capacity fees = storage capacity unit price * monthly storage capacity used|
|Request fees||Calculated based on the number of requests at a unit price that varies by storage class||Request fees = unit price per 10,000 requests * monthly accumulated number of requests / 10,000|
|Data retrieval fees||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 * monthly amount of data retrieved|
|Traffic fees||Calculated based on the public network downstream traffic, CDN origin-pull traffic, and cross-region replication traffic at a unit price that varies by traffic type||Traffic fees = unit price per GB * daily accumulated traffic|
