    Billable items in COS include storage usage, requests, data retrievals, traffic, and management features. The following describes each billable item in detail.

    Note:

    COS offers the following object storage classes for different access frequencies and disaster recovery needs: INTELLIGENT TIERING, STANDARD, STANDARD_IA, ARCHIVE, and DEEP ARCHIVE. For more information, please see Storage Class Overview.

    Storage Usage Fees

    Billable Item Applicable Storage Class        Definition Billing Description
    Storage usage INTELLIGENT TIERING
    STANDARD
    STANDARD_IA
    ARCHIVE
    DEEP ARCHIVE
    Storage usage is the actual storage capacity consumed by your data. It is billed based on the actual size of the storage capacity used.
  • Monthly billing cycle
  • Storage usage fees = Storage usage unit price x Monthly storage usage
  • Monthly storage usage = Sum of "daily storage usage" in the month/Number of days in the month
  • Daily storage usage = Sum of "5-minute storage usage"/288 (number of statistical points)
  • Billing restrictions

    1. STANDARD_IA: Storage duration of fewer than 30 days will be calculated as 30 days. A single stored file less than 64 KB will be calculated as 64 KB; otherwise, files are calculated based on their actual sizes.
    2. ARCHIVE: available in public cloud regions only. Storage duration of fewer than 90 days will be calculated as 90 days. A single stored file less than 64 KB will be calculated as 64 KB; otherwise, files are calculated based on their actual sizes.
    3. DEEP ARCHIVE: available only in Beijing, Guangzhou, and Chengdu regions. Storage duration of fewer than 180 days will be calculated as 180 days. A single stored file less than 64 KB will be calculated as 64 KB; otherwise, files are calculated based on their actual sizes.
    4. If you successfully uploaded an object to STANDARD_IA or ARCHIVE with versioning not enabled, COS will delete the existing object (if any) that has the same name. In this case, storage fees will still be incurred for early deletion of the object.
    5. For INTELLIGENT TIERING, storage usage fees of objects are consistent with the storage class after storage class movement. In addition, you will be charged the object monitoring fees.

    Request Fees

    Request fees include the fees incurred by user requests and backend requests generated by feature configuration.

    • User requests: include requests to Tencent COS to upload, download, query, delete, and perform other operations via APIs, SDKs, or console.
    • Backend requests: include requests to delete STANDARD copies after lifecycle transition or STANDARD copies restored from ARCHIVED expired, read/write data for cross-region replication, and deliver inventory reports.
    Billable Item Applicable Storage Class        Definition Billing Description
    Number of requests INTELLIGENT TIERING
    STANDARD
    STANDARD_IA
    ARCHIVE
    DEEP ARCHIVE
    Calculated based on the number of requests sent
  • Monthly billing cycle
  • If the accumulated number of requests is less than 10,000, the bill is calculated as 10,000.
  • Request fees = Unit price per 10,000 requests x Monthly accumulated number of requests/10,000
  • Billing restrictions

    1. Both successful and failed requests are billed.
    2. The minimum counting unit for the number of requests is 10,000. Therefore, if the monthly accumulated requests is less than 10,000, you will still be billed for 10,000 requests, regardless of request success or failure.
    3. Data in the ARCHIVE and DEEP ARCHIVE storage classes cannot be read or downloaded. If you restore objects from ARCHIVE to STANDARD, you will be billed at STANDARD rates; if you restore objects in the DEEP ARCHIVE storage class, you will be billed at DEEP ARCHIVE rates.
    4. Retrieving DEEP ARCHIVED data will incur data retrieval request fees.
    5. For INTELLIGENT TIERING, request fees are subject to those of the storage class after storage class movement.

    Data Retrieval Fees

    Billable Item Applicable Storage Class Definition Billing Description
    Data retrieved STANDARD_IA
    ARCHIVE
    Calculated based on the amount of data retrieved
  • Monthly billing cycle
  • Data retrieval fees = Unit price per GB x Monthly amount of data retrieved
  • DEEP ARCHIVE
  • Daily billing cycle
  • Data retrieval fees = Unit price per GB x Daily amount of data retrieved
  • Billing restrictions

    Storage classes suitable for cold data include STANDARD_IA, ARCHIVE, and DEEP ARCHIVE. To read or download data in STANDARD_IA, COS needs to retrieve it first. ARCHIVED data cannot be read or downloaded until it is restored (unfrozen) to the STANDARD storage class.

    Traffic Fees

    Traffic fees are calculated based on the accumulated traffic generated by reading the data stored.

    Billable Items Applicable Storage Class Definition Billing Description
    Public network upstream traffic INTELLIGENT TIERING
    STANDARD
    STANDARD_IA
    ARCHIVE
    DEEP ARCHIVE
    Traffic generated by data transfer from the client to COS over the Internet Free
    Private network upstream traffic Traffic generated by data transfer from the client to COS over Tencent Cloud private network Free
    Public network downstream traffic Traffic generated by data transfer from COS to the client over the Internet
  • Daily billing cycle
  • Public network downstream traffic fees = Unit price per GB x Daily accumulated public network downstream traffic
  • Private network downstream traffic Traffic generated by data transfer from COS to the client over the Tencent Cloud private network Free
    CDN origin-pull traffic Traffic generated by data transfer from COS to a Tencent Cloud CDN edge server
  • Daily billing cycle
  • CDN origin-pull traffic fees = Unit price per GB x Daily accumulated CDN origin-pull traffic
  • Cross-region replication traffic Traffic generated by replicating data from a bucket in one region to a bucket in another region
  • Daily billing cycle
  • Cross-region replication traffic fees = Unit price per GB x Daily accumulated cross-region replication traffic
  • Global acceleration traffic Traffic generated by data transfer using an acceleration endpoint through the global acceleration feature. This traffic consists of upstream traffic and downstream traffic:
  • Upstream traffic is the traffic generated by uploading data to COS using an acceleration endpoint.
  • Downstream traffic is the traffic generated by viewing or downloading COS data using an acceleration endpoint.
  • Daily billing cycle
  • Global acceleration traffic fees = Unit price per GB x Daily accumulated global acceleration traffic
  • Billing restrictions

    1. ARCHIVED data cannot be read or downloaded. The data can only be read after being restored to the STANDARD storage class. Therefore, traffic generated from these requests is counted in the STANDARD storage class.
    2. Public network downstream traffic is generated when the data is returned to COS through origin-pull using a third-party CDN service.
    3. After CDN acceleration is enabled, CDN origin-pull traffic is generated when a user browses or downloads COS data on the client through a Tencent Cloud CDN acceleration endpoint.
    4. Public network downstream traffic is generated when a user downloads objects through object links or browses objects through a static website endpoint.
    5. Cross-region replication traffic is generated when you replicate data from a bucket in one region to a bucket in another region using APIs or the cross-region replication feature. The traffic fees vary, depending on the region where the source bucket resides.
    6. For INTELLIGENT TIERING, traffic fees are subject to those of the storage class after storage class movement.

    Note:

    Tencent Cloud products within the same region access each other over the private network by default and no traffic fees will be incurred. For more information on how to identify private network access, please see COS Access via Private Network and Public Network.

    The figure below shows the traffic fees incurred by data transmitted from COS to an end user with Tencent Cloud CDN acceleration endpoint enabled and disabled, respectively.

    Management Feature Fees

    Management feature fees are calculated based on the use of COS management features, such as inventory and COS Select.

    Billable Items Applicable Storage Class Definition Billing Description
    Inventory feature N/A Fees incurred from listing bucket objects after the inventory feature is enabled
  • Daily billing cycle
  • Billed per million objects listed
  • COS Select STANDARD
    STANDARD_IA
    Fees incurred from extracting objects when the COS Select feature is enabled

  • Object tagging N/A Once you enable the object tagging feature, COS will bill you based on the number of object tags set
