Expenses and Costs:DescribeInstanceAmortizedCostByAmortizationPeriod

Last Updated:Oct 28, 2025

Queries the monthly amortized costs of instances for a specified amortization month.

Operation description

  • Amortized costs cannot be used for settlement or reconciliation. They are used to allocate your subscription and pay-as-you-go fees based on specified allocation rules.

  • The final data for a month is available after 12:00 on the sixth day of the following month. The reason for this delay is that scenarios such as delayed billing, refunds, bill adjustments, and overdue payment write-offs can occur during the month. The data for the current month does not include unsettled pay-as-you-go fees for which bills have not yet been generated.

  • Amortized cost data from the last 12 months is available.

  • Data for attached resources is reflected in the amortized costs 48 hours after the split bill is generated. To use this feature, you must first enable split bills. Data for items that are not attached resources is updated 48 hours after the detailed bill is generated.

  • For months before August 2021, amortized costs are not updated intra-month. They are updated only after 12:00 on the sixth day of the following month. Consequently, specific costs for attached resources, such as domain names, buckets, and EIPs, for products such as CDN, OSS, and Internet Shared Bandwidth are not available for these months.

  • Amortized cost data is available for querying 48 hours after you enable the Amortized Cost feature.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
