Object Storage Service:Billing overview

Last Updated:Oct 31, 2023

This topic describes the billing methods, billable items, and pricing of Object Storage Service (OSS).

Billing methods

OSS supports the following billing methods:

  • Pay-as-you-go: By default, the pay-as-you-go billing method applies to all billable items. You are charged for the actual usage of each billable item. Fees are paid after you use resources. This billing method is ideal for scenarios in which resource usage is difficult to predict. For more information, see Pay-as-you-go.

  • Subscription (resource plans): OSS provides resource plans to offset fees generated for specific billable items. You can purchase resource plans that cover specific billable items at favorable prices. Resources are consumed before fees are offset by resource plans. Resource plans are ideal for scenarios in which resource usage is easy to predict. For more information, see Overview.

  • Storage capacity units (SCUs): You can use SCUs to offset storage fees that are generated for using OSS and other Alibaba Cloud storage services. For more information, see SCUs.

Note
  • Compared with the pay-as-you-go billing method, resource plans and SCUs are more cost-effective.

  • Each resource plan and SCU has a quota for resource usage. If your resource usage exceeds the quota, you are charged for the excess resource usage based on the pay-as-you-go billing method. We recommend that you purchase resource plans and SCUs based on your workloads and business scale.

Billing cycle

OSS calculates all resource usage by hour and charges fees for actual usage. Bills are generally generated within 1 hour after a billing cycle ends. The time when bills are generated is determined by the system. For example, you are billed at 09:30:00 for the fees that are generated from 08:00:00 to 09:00:00 of the same day.

Important

The bill that you receive at 09:30:00 may include only the fees that are generated from 07:00:00 to 08:00:00 because of system latency.

Billing formulas

You are charged fees by hour based on actual usage. Fees are calculated based on the following formula: Fees = Actual usage (GB) × Unit price per hour.

Important

Storage fees are calculated in USD per GB-month, as indicated on the OSS pricing page. When you use the pay-as-you-go billing method, fees are calculated based on the following formula: Fees = Actual usage (GB) × Unit price per hour. Therefore, when you calculate storage fees charged based on actual storage usage, you must convert GB-month to GB-hour to calculate the fees based on the following formula: Unit price in USD per GB-hour = Unit price in USD per GB-month/30/24. For example, the unit price for the storage of Standard LRS objects is USD 0.0173 per GB-month, and the unit price in GB-hour is USD 0.000024 per GB-hour (0.0173/30/24).
