Yearly/Monthly Billing
If you expect to use resources for a longer period, you can save money by selecting yearly/monthly billing. Yearly/Monthly is a prepaid billing mode. You pay in advance for using a cloud service, and in exchange, you get a discounted rate. This topic describes the billing rules for yearly/monthly bandwidth packages.
Application Scenarios
If you want to ensure resource stability over a certain period of time, yearly/monthly billing is a good choice for the following types of workloads:
- Long-term workloads with stable resource requirements, such as official websites, online malls, and blogs.
- Long-term projects, such as scientific research projects and large-scale events.
- Workloads with predictable traffic bursts, for example, e-commerce promotions or festivals.
- Workloads with high data security requirements
Billed Item
Cloud connections are free. To enable high-quality communication across regions, you need to purchase yearly/monthly bandwidth packages. If your VPCs are in the same region, there is no need to buy a bandwidth package.
Bandwidth packages are billed by the term your purchase.
Billed Item |
Description |
---|---|
Bandwidth package |
Used for communication between regions within a geographic region or across geographic regions. The bandwidth billing option is By bandwidth. |
Billed Usage Period
A yearly/monthly bandwidth package is billed for the purchased duration. The billing starts when you activated or renewed the subscription, and ends at 23:59:59 of the expiry date.
For example, if you purchased a one-month bandwidth package on March 08, 2023, 15:50:04, the billed usage period is from March 08, 2023, 15:50:04 to April 08, 2023, 23:59:59.
Billing Example
- 15:50:04 on March 08, 2023 to 23:59:59 on April 08, 2023
- 23:59:59 on April 8, 2023 to 23:59:59 on May 8, 2023
You will be billed for both usage periods. Table 2 shows the billing formula.

Tiered pricing is used based on the bandwidth. |
Figure 1 shows how the total price is calculated.
The prices in the figure are just examples. The actual prices are displayed on Cloud Connect Pricing Details.
Price Change After Specification Change
If the specifications of a yearly/monthly bandwidth package no longer meet your needs, you can change the specifications on the console. The system will recalculate the price and either bill or refund you the difference.
- If you upgrade the bandwidth package, you need to pay the difference in price.
- If you downgrade the bandwidth package, Huawei Cloud will refund you the difference.
Assume that you purchased a one-month 150-Mbit/s bandwidth package for communication within the Chinese mainland (billed by bandwidth) on April 8, 2023 and changed the bandwidth to 200 Mbit/s on April 18, 2023. The price of the original bandwidth is $3,767.5 USD, and the price of the new bandwidth is $4,347 USD. The price difference will be calculated as follows:
Price difference = New bandwidth price × Remaining period - Original bandwidth price × Remaining period
The remaining period is the remaining days of each calendar month divided by the maximum number of days in each calendar month. In this example, the remaining period is 0.6581.
12 (Remaining days in April)/30 (Days in April) + 8 (Remaining days in May)/31 (Days in May) = 0.6581
Price difference = $4,347 USD x 0.6581 – $3,767.5 USD x 0.6581 = $377.7181 USD
For more information, see Pricing of a Changed Specification.
Impact of Expiration
Figure 2 shows the statuses a yearly/monthly bandwidth package can go through throughout its lifecycle. After a bandwidth package is purchased, it enters the valid period and runs normally during this period. If the bandwidth package is not renewed after it expires, before being deleted, it first enters a grace period and then a retention period.
Expiration Reminder
The system will send you a reminder (by email, SMS, or in-app message) 7 days before a yearly/monthly bandwidth package expires to remind you to renew the subscription.
Impact of Expiration
- Grace period
If the yearly/monthly bandwidth package is not renewed after it expires, it changes to the Expired state and enters a grace period.
- Retention period
If the yearly/monthly bandwidth package is not renewed after the grace period ends, its status turns to Frozen and it enters a retention period. You cannot perform any operations on the bandwidth package while it is in the retention period.
- Permanent release
If the yearly/monthly bandwidth package is not renewed by the time the retention period ends, the bandwidth package will be released and data cannot be restored.
