    KMS

    The billing of KMS is based on two factors: CMK storage and API calls, as detailed below:

    Item Price
    CMK storage (USD/key/day) Tencent Cloud managed CMKs Free
    Customer managed CMKs 0.06 USD/key/day
    API calls (USD/10,000 calls) First 20,000 calls Free
    API calls 0.18 USD/10,000 calls

    Settlement cycle

    KMS is a monthly pay-as-you-go service. The fees for one month are calculated, billed, and charged on the 3rd to 5th days of the following month.

    CMK storage fees

    This refers to the fees for storing the CMKs created in KMS. The CMK storage fees are billed daily, that is, the cumulative CMKs under a specified account will be billed on a daily basis.

    • Tencent Cloud managed CMKs: free of charge.
      A Tencent Cloud managed CMK is a CMK that is automatically created for you when a Tencent Cloud service (such as COS or TDSQL) calls the KMS service.
    • Customer managed CMKs: 0.06 USD/key/day.
      A customer managed CMK is a CMK that you create in the console or through APIs.

    Note:

    • Limit on the total number of CMKs: up to 200 CMKs can be created under each account in each region, excluding the ones in “Pending Deletion” status and Tencent Cloud managed CMKs. If you need to create more CMKs, please submit a ticket or contact your Tencent Cloud sales rep.
    • CMK billing status: only customer managed CMKs in "Pending Deletion" status are free of charge.

    API call fees

    KMS provides a free quota of 20,000 API calls. After the free quota is used up, API calls will be billed monthly, that is, the cumulative API calls under a specified account in one month will be billed on a monthly basis.

    API calls: 0.18 USD/10,000 calls, billed monthly.

    Note:

    If there are less than 1,000 API calls, fees will be billed for 1,000 calls.
