Pricing

The fees in this topic are for reference only. For actual fees, see the console.

A computing resource plan is priced at USD 0.03611/CCU*H. Compared with the pay-as-you-go unit price of computing resources for ApsaraDB for ClickHouse Enterprise Edition in the Chinese mainland, the approximate discount is 46.66%.

Offset rules

A computing resource plan is priced the same in all regions, including the Chinese mainland, China (Hong Kong), and regions outside China. However, the offset factor varies with the region, so the amount of resources that a computing resource plan can offset also varies with the region.

After you purchase a computing resource plan, the plan automatically starts to offset eligible computing resource fees.
Computing resource usage that exceeds the computing resource plan is billed at the pay-as-you-go unit price.
After a computing resource plan is fully offset, the billing method of the computing resources of the instance reverts to normal pay-as-you-go billing.
The plan capacity that an instance consumes is calculated as follows:

Resource plan amount required to offset the CCU usage of an instance = Actual CCU usage of the instance * Offset factor of the region in which the instance resides

Regional offset factors

The offset factor is used to convert the capacity that a resource plan can offset in different regions.
In a region whose offset factor is greater than 1, the resource plan amount required for the offset is greater than the actual resource usage, but the final fee is still lower than the pay-as-you-go fee. For more information, see .
In a region whose offset factor is 1, the resource plan amount required for the offset equals the actual resource usage. In a region whose offset factor is less than 1, the required resource plan amount is less than the actual resource usage.

Region	Offset factor
China (Beijing), China (Hangzhou), China (Shanghai), China (Shenzhen)	1.00
China (Hong Kong)	1.62
Singapore	1.49
Japan (Tokyo)	1.64
US (Virginia)	1.16
Germany (Frankfurt)	1.56

Example 1: How a computing resource plan reduces costs

You have an Enterprise Edition instance in Singapore whose computing resources are used at 10 CCU for 1 hour. The fees in different cases are as follows:

In pay-as-you-go billing, your fee is USD 2.0595 = 10 CCU*H * USD 0.20595/CCU*H.
If you use a computing resource plan for the offset, the required resource plan amount is 14.9 CCU*H = 10 CCU*H * 1.49, and the resource plan fee is USD 0.538039 = 14.9 CCU*H * USD 0.03611/CCU*H.
For the pay-as-you-go fees of computing resources, see Fees for Enterprise Edition.

The preceding analysis shows that although the computing resources of your instance are used at 10 CCU, 14.9 CCU*H of the resource plan is required for the offset. However, compared with pay-as-you-go billing, using a computing resource plan for the offset saves you USD 1.521461 = USD 2.0595 - USD 0.538039, which is more than 73% of the cost.

Example 2: How a computing resource plan is offset

Assume that your account has the following resources:

A computing resource plan of 360 CCU*H.
An Enterprise Edition instance in Singapore.
An Enterprise Edition instance in US (Virginia).
An Enterprise Edition instance in Hangzhou.
The computing resource usage of each instance within one hour and the computing resource plan amount required to offset the actual computing resource usage are described in the following table.

Instance	Computing resource usage	Resource plan amount required for the offset
Enterprise Edition instance in Singapore	8 CCU for 1 hour.	`8 CCU` * `1 H` * `1.49` = `11.92 CCU*H`
Enterprise Edition instance in US (Virginia)	12 CCU for the first 30 minutes, and the computing resource load decreases to 8 CCU for the last 30 minutes.	`12 CCU` * `0.5 H` * `1.16` + `8 CCU` * `0.5 H` * `1.16` = `11.6 CCU*H`
Enterprise Edition instance in Hangzhou	16 CCU for 1 hour.	`16 CCU` * `1 H` * `1` = `16 CCU*H`

After this hour ends, the remaining capacity of the computing resource plan changes from 360 CCU*H to 360 CCU*H - 11.92 CCU*H - 11.6 CCU*H - 16 CCU*H = 320.48 CCU*H.
