      Storage usage refers to the used storage capacity. You are charged by the objects' size and how long you stored them. For different storage classes, the unit price, minimum object size, and minimum storage duration are different as described below. The actual costs depend on the use case and storage class of the object.
      Note:
      For more information on storage classes, see Storage Class Overview.
      The billing unit of the storage capacity billing item and storage capacity packages is GB, and the capacity unit conversion ratio is 1:1,024.For example, 1 TB of standard storage capacity equals 1,024 GB. A standard storage capacity package of 1 TB can deduct fees of 1,024 GB of standard storage capacity.

      Early deletion

      Description
      Involved Storage Class
      Early deletion
      refers to the deletion of an object in the STANDARD_IA, MAZ_STANDARD_IA, ARCHIVE, or DEEP ARCHIVE storage class performed before it meets the minimum storage duration requirement after being uploaded.
      
      
      Note: Early deletion fees will be incurred in storage classes with the minimum storage duration requirement, i.e., STANDARD_IA, MAZ_STANDARD_IA, ARCHIVE, and DEEP ARCHIVE.
      
      
      Billing rule:
      If an object is deleted before it meets the minimum storage duration requirement, the storage usage fees incurred by it will be calculated based on the minimum storage duration as detailed below:
      STANDARD_IA or MAZ_STANDARD_IA storage of data for less than 30 days will be calculated as 30 days.
      ARCHIVE storage of data for less than 90 days will be calculated as 90 days.
      DEEP ARCHIVE storage of data for less than 180 days will be calculated as 180 days.
      
      The following operations may cause early deletion:
      1. You delete an object in advance before it meets the minimum storage duration requirement.
      2. You modify the attributes of an object before it meets the minimum storage duration requirement, such as custom header or storage class. In this case, COS will delete the original object after successful modification, and storage fees incurred by early object deletion will be charged.
      3. When an object does not meet the minimum storage duration, you can perform data transition through the lifecycle feature, deleting the original object of the same name after data transition. At this time, storage usage fees incurred by the early deletion of the object will be charged.
      4. You upload an object with the same name as an existing object to a bucket with versioning not enabled before the existing object meets the minimum storage duration requirement. In this case, COS will delete the existing object, and storage fees incurred by early object deletion will be charged.

      STANDARD Storage Usage Fees
      STANDARD_IA Storage Usage Fees
      There are several types of storage capacity packages:
      STANDARD capacity package: Used to deduct the STANDARD capacity. It cannot be used to deduct the MAZ_STANDARD capacity.
      STANDARD_IA capacity package: Used to deduct the STANDARD_IA capacity. It cannot be used to deduct the MAZ_STANDARD_IA capacity.
      Within the validity period of the storage capacity package, the storage space occupied each day (including the purchase day) can be deducted from the specifications of the storage capacity package. The insufficient part will be billed on a pay-as-you-go basis.
      Note:
      Billing days: If settled monthly, billing is based on 30 days per month. If settled daily, billing is based on the actual number of days in each month.
      Bill fluctuation: With unchanged usage each month, storage capacity bills will fluctuate. For a full month's use, January is billed for 31 days, February for 28 (or 29) days, and April for 30 days.

      Billing Examples

      Note:
      Prices in the examples below are for reference only. For the actual prices, see Pricing | Cloud Object Storage.
      The storage capacity is calculated in binary, for example, 1 TB = 1024 GB.
      

      Example 1: STANDARD Storage Usage Fees + STANDARD Request Fees

      Assume that on January 1, 2024, user A uploaded 10 GB of data of the STANDARD type to a COS bucket in Guangzhou region, and spent 0.1216 USD on the same day to purchase a 10-GB STANDARD capacity package valid for one month and universal in the Chinese mainland (with a validity period of 32 days, effective from 2024-01-01 0:00:00 to 2024-02-01 23:59:59). On the same day, 0.01 ten thousand STANDARD read/write requests were made, with no other activities for the rest of the time, and the 10-GB data was stored in COS throughout. User A's pay-as-you-go charges are not discounted and are billed at the published price; the resource package enjoys an official discount.
      
      Settlement is based on the charges incurred on the previous day. Therefore, user A's total fees for January 2024 include:
      STANDARD storage usage fees: The STANDARD storage usage fees from 2024-01-01 0:00:00 to 2024-01-31 23:59:59, settled daily.
      STANDARD request fees: The STANDARD read/write request fees from 2024-01-01 0:00:00 to 2024-01-31 23:59:59, settled daily.
      
      The published prices for the relevant billing items in the Guangzhou region are as follows:
      STANDARD capacity: 0.016 USD/GB/Month (Daily published price = Monthly published price/30)
      STANDARD capacity resource package: 0.1216 USD
      STANDARD read/write requests: 0.002 USD/10,000 Times
      
      Fees analysis:
      1. STANDARD capacity fees: Using the STANDARD capacity resource package, 10 GB is deducted daily. Total: 0.1216 USD.
      2. STANDARD request fees: Pay-as-you-go, (0.002 USD/10,000 times) x (0.01 x 10,000 times) = 0.00002 USD.
      3. Total fees: STANDARD capacity fees + STANDARD request fees = 0.1216 USD + 0.00002 USD = 0.12162 USD
      
      In conclusion, user A's total fees in January is 0.12162 USD.
      

      Example 2: STANDARD_IA storage usage fees + STANDARD_IA request fees

      Assume that on November 1, 2020, user B uploaded 10 GB of data (including 10,000 pieces of 30 KB objects) to a bucket residing in Guangzhou region in the STANDARD_IA storage class, generating 100 requests. Apart from this, user B did not perform any other operations in November. As fees for a day were settled the next day:
      STANDARD_IA storage usage fees: Settled daily starting from November 2, 2020.
      STANDARD_IA request fees: Settled on November 2, 2020.
      Fees analysis:
      STANDARD_IA storage usage = 10 GB + 10,000 * 30 KB = 10.286 GB
      STANDARD_IA storage usage fees = 0.018 USD/GB/month / 30 * 10.286 GB * 30 days = 0.19 USD
      STANDARD_IA request fees = 0.01 USD/10,000 requests * 100 requests / 10,000 = 0.0001 USD
      In summary, the total bill for user B in November is calculated as follows: 0.19 + 0.0001 = 0.1901 USD.
