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 and subscription (resource plan). By default, the pay-as-you-go billing method is used. You can use resource plans to offset resource usage fees of common paid features of OSS.
  • Pay-as-you-go: You are charged for the actual usage of each billable item. Fees are deducted after resources are consumed. This billing method is ideal for scenarios in which the usage of resources is difficult to predict.
  • Subscription (resource plan): You can purchase resource plans that are subject to specific billable items at discount prices. Resources are consumed before fees are offset by resource plans. Resource plans are ideal for scenarios in which the usage of resources is easy to predict.
Note
  • Compared with the pay-as-you-go billing method, resource plans are more cost-effective.
  • Each resource plan has a quota of resource usage. If the quota is exceeded, you are charged for the excess resource usage based on the pay-as-you-go billing method. We recommend that you purchase resource plans 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 one 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.

Notice 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.

Formula

OSS charges fees by hour based on actual usage. Fees are calculated based on the following formula: Fees = Actual usage (GB) × Unit price per hour.
Notice Storage fees are calculated in USD per GB-month, as instructed 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 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).
