A compute plan lets you pre-purchase compute capacity for ApsaraDB for ClickHouse Enterprise Edition at a significant discount. Compared to pay-as-you-go pricing in the Chinese mainland, a compute plan saves approximately 46.66% on compute costs. Even in regions with higher offset factors, the effective cost remains well below the pay-as-you-go rate.
What a compute plan covers
A compute plan offsets the cost of Enterprise Edition compute resources only. It does not cover storage, networking, or other non-compute charges.
Eligible resources: ApsaraDB for ClickHouse Enterprise Edition compute resources
Billing method: Subscription-based, with a fixed validity period of three years
Automatic offset: After purchase, the plan automatically offsets eligible compute resource usage across all supported regions under your account
Overflow billing: After a plan is fully consumed, compute resources are billed at the pay-as-you-go rate
Supported regions
Compute plans support the following nine regions:
Region group | Regions |
The Chinese mainland | China (Beijing), China (Hangzhou), China (Shanghai), China (Shenzhen) |
Asia Pacific | China (Hong Kong), Singapore, Japan (Tokyo) |
Americas | US (Virginia) |
Europe | Germany (Frankfurt) |
Key rules
Rule | Details |
Minimum capacity | 3,000 CCU (Compute Capacity Unit) |
Validity period | 3 years (non-renewable) |
Stacking | Purchase and stack multiple plans without limit |
Refunds | Not supported. Plans cannot be unsubscribed. |
Because compute plans cannot be renewed or refunded, estimate your resource usage carefully before purchasing. You can always purchase additional plans and stack them if your usage grows.
Pricing
The prices in this topic are for reference only. For the actual prices, see the console.
The unit price of a compute plan is USD 0.03611/CCU*H, which is approximately 46.66% lower than the pay-as-you-go unit price for Enterprise Edition compute resources in the Chinese mainland.
How offset works
Compute plans are priced the same in all regions. However, each region has a different offset factor (regional pricing multiplier) that determines how much plan capacity is consumed per unit of actual usage.
Offset formula
Plan capacity consumed = Actual CCU usage x Offset factorFor example, if an instance uses 10 CCU*H in Singapore (offset factor 1.49), the plan capacity consumed is 10 x 1.49 = 14.9 CCU*H.
Regional offset factors
Region | Offset factor |
China (Beijing), China (Hangzhou), China (Shanghai), China (Shenzhen) | 1.00 |
US (Virginia) | 1.16 |
Singapore | 1.49 |
Germany (Frankfurt) | 1.56 |
China (Hong Kong) | 1.62 |
Japan (Tokyo) | 1.64 |
In regions where the offset factor is greater than 1, the plan consumes more capacity than the actual resource usage. However, the total cost is still lower than the pay-as-you-go price. See Example 1 below for a detailed comparison.
Offset examples
Example 1: Cost savings in a single region
This example compares the cost of running an Enterprise Edition instance in Singapore with and without a compute plan.
Scenario: An instance runs at 10 CCU for 1 hour in Singapore.
Pay-as-you-go cost:
Item | Value |
Usage | 10 CCU*H |
Unit price (Singapore) | USD 0.20595/CCU/H |
Total cost | USD 2.0595 (10 x USD 0.20595) |
For pay-as-you-go prices by region, see Enterprise Edition pricing.
Compute plan cost:
Item | Value |
Actual usage | 10 CCU*H |
Offset factor (Singapore) | 1.49 |
Plan capacity consumed | 14.9 CCU*H (10 x 1.49) |
Unit price (plan) | USD 0.03611/CCU*H |
Total cost | USD 0.538039 (14.9 x USD 0.03611) |
Savings: USD 2.0595 - USD 0.538039 = USD 1.521461, a cost reduction of approximately 73%.
Example 2: Multiple instances sharing a plan
This example shows how a single compute plan offsets usage across instances in different regions.
Setup: Your account has a compute plan of 360 CCU*H and three Enterprise Edition instances.
Usage for one hour:
Instance | Usage | Offset factor | Plan capacity consumed |
Singapore | 8 CCU for 1 hour | 1.49 | 8 x 1 x 1.49 = 11.92 CCU*H |
US (Virginia) | 12 CCU for the first 30 min, then 8 CCU for the last 30 min | 1.16 | (12 x 0.5 x 1.16) + (8 x 0.5 x 1.16) = 11.6 CCU*H |
China (Hangzhou) | 16 CCU for 1 hour | 1.00 | 16 x 1 x 1.00 = 16 CCU*H |
Total | 39.52 CCU*H |
Remaining plan capacity: 360 - 11.92 - 11.6 - 16 = 320.48 CCU*H

View offset usage
To check how much plan capacity has been consumed and how much remains:
Log on to the User Center.
In the left navigation pane, click Manage Reserved Instances.
On the Manage Reserved Instances page, select Resource Packages as the resource type.
On the Instances tab, find your compute plan in the Product Name and Resource Package Name columns. This tab shows the total and remaining capacity.
To view a detailed breakdown of each offset, click the Details tab. This tab shows the offset amount, the original instance usage, and the offset factor for each deduction.
In the console, compute plans are listed under resource plans. The terms "resource plan" and "compute plan" refer to the same product when used in the context of ApsaraDB for ClickHouse Enterprise Edition.
