      Billing Mode and Calculation Formula

      Billing Mode Calculation Formula
      Pay-as-you-go
    • Monthly billing cycle
    • Storage usage fees = Unit price x Monthly storage usage
    • Monthly storage usage = Sum of the "daily storage usage" in the month/Number of days in the month
    • Daily storage usage = Sum of the "5-minute usage"/288 (number of statistical points)
      		•

      Billing Examples

      Note：

      • Prices in the examples below are for reference only. For the actual prices, please see COS Pricing.
      • The storage capacity is calculated in binary. For example, 1 TB = 1,024 GB.
      • The minimum number of billable requests is 10,000. Therefore, if the number of monthly accumulated requests is less than 10,000, you will still be billed for 10,000 requests, regardless of whether the request succeeds or fails.

      Example 1: STANDARD storage usage fees + STANDARD request fees

      Assume that on November 1, 2020, user A uploaded 10 GB of data to a bucket residing in the Guangzhou region in the STANDARD storage class, generating 100 requests. Apart from this, user A did not perform any other operations in November. As storage usage fees and request fees are calculated and billed on the 1st in the next month, the storage usage and request fees will be calculated and billed on December 1, 2020, as follows:

      • Pay-as-you-go:
        • STANDARD storage usage fees = 0.024 USD/GB/month x 10 GB = 0.24 USD
        • STANDARD request fees = 0.002 USD/10,000 requests x 10,000 requests = 0.02 USD

      In summary, the total bill for user A in November is calculated as follows: 0.24 + 0.02 = 0.26 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 (i.e. 10,000 pieces of 34 KB objects) to a bucket residing in the 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 storage usage fees and request fees are calculated on the 1st in the next month, the storage usage fees and request fees will be calculated and billed on December 1, 2020 as follows:

      • Pay-as-you-go:
        • STANDARD_IA storage usage = 10 GB + 10,000 x 30 KB = 10.286 GB
        • STANDARD_IA storage usage fees = 0.018 USD/GB/month x 10.286 GB = 0.19 USD
        • STANDARD_IA request fees = 0.01 USD/10,000 requests x 10,000 requests = 0.01 USD

      In summary, the total bill for user B in November is calculated as follows: 00.19 + 0.01 = 0.2 USD.
