Storage fees
MaxCompute charges for stored data, such as tables and resources, and backup data based on the size of a single replica. This topic describes the billing rules for different storage types.
Billing overview
Data in MaxCompute is stored using columnar compression, with a typical compression ratio of approximately 5:1. By default, data is stored redundantly across three replicas, but you are billed for the compressed size of only a single replica.
MaxCompute supports the following storage types:
Type | Use case | Billed items | |
Single-zone storage | Standard storage | Frequently accessed hot data | Storage fee |
Infrequent Access (IA) storage | Infrequently accessed data | Storage fee + Data access fee | |
Long-term storage | Rarely accessed cold data | Storage fee + Data access fee | |
Multi-zone storage | Standard storage | Hot data that requires cross-zone disaster recovery | Storage fee |
Infrequent Access (IA) storage | Data that requires cross-zone disaster recovery | Storage fee + Data access fee | |
Long-term storage | Cold data that requires cross-zone disaster recovery | Storage fee + Data access fee | |
Backup storage | Data backups (for retention periods longer than 1 day) | Storage fee | |
Types
Single-zone storage:
Data is redundantly stored across multiple devices within a single zone. This ensures data durability and availability in the event of a hardware-level failure.
Multi-zone storage:
If a zone fails, the disaster recovery capability of multi-zone storage maintains service availability and protects data. For more information, see zone disaster recovery.
Backup storage
Billing formulas
Storage fee = Average daily storage volume × Unit price. The average daily storage volume is calculated as: (Sum of hourly storage snapshots) ÷ 24.
Data access fee = Amount of data accessed × Unit price. This fee applies only to Infrequent Access (IA) storage and Long-term storage.
Changing the storage tier of a table or partition from Infrequent Access (IA) storage to Standard storage or Long-term storage incurs a data access fee for the entire table or partition. The same rule applies when changing from Long-term storage.

Usage notes
Overdue payments and service suspension: If a project has an overdue payment, its services may be suspended. To avoid service interruptions, pay your outstanding balance promptly. For more information, see Overdue payments and service suspension.
Bill generation time: Storage bills are typically generated within three hours after a billing cycle ends, but may take up to six hours. For example, the bill for the previous day is usually generated before 06:00 on the next day. Actual generation times may vary.
After a bill is generated, the fees are automatically deducted from your account balance. You can view your consumption details on the Bill Details page.
