      Billable Items

      COS billable items are calculated as follows:
      Billable Item
      Description
      Calculation Formula
      Storage usage fees
      Calculated based on the storage usage at a unit price that varies by storage class.
      Storage usage fees = monthly unit price / 30 * daily storage usage * number of days
      Daily storage usage = sum of "5-minute usage" / 288 (number of statistical points)
      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 * daily 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 the STANDARD_IA or ARCHIVE storage class is downloaded.
      Data retrieval fees = unit price per GB * daily amount of data retrieved
      Traffic fees
      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 * daily accumulated traffic
      Management feature fees
      Fees incurred by management features that you enabled and used, including inventory, extraction, batch operation, and object tagging.
      Inventory fees = unit price per million objects listed * number of objects listed / 1 million
      COS extraction fees = unit price per GB * daily accumulated amount of data extracted
      Batch operation fees include job fees and object processing fees.
      
      Job fees = unit price per job * number of jobs created
      Object processing fees = unit price per 10,000 objects processed * number of objects / 10,000
      Object tagging fees = unit price per 10,000 tags * number of tags / 10,000

      Examples

      Assume that on March 1, 2019, user A activated COS and uploaded 100 GB of files to the STANDARD storage class in a bucket in Beijing region. On March 15, the user downloaded 10 GB of data over the public network. 10,000 STANDARD read/write requests were generated. Apart from these operations, the user did not perform any other operations in March.
      Therefore, the following fees were incurred in March:
      STANDARD storage usage fees: The storage usage fees for 100 GB of data in the month.
      Traffic fees: The public network downstream traffic fees for 10 GB of data in the month.
      Request fee: The request fees for 10,000 STANDARD read/write requests in the month. Among them, uploading data generated STANDARD write requests, and downloading data generated STANDARD read requests.
