Yearly/Monthly Billing

If you expect to use resources for a longer period, you can save money by selecting yearly/monthly billing. You can pre-purchase CFW resources at discounted prices. This section describes the billing rules of yearly/monthly CFW resources.

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
For long-term projects
Workloads with predictable traffic bursts
Workloads with high data security requirements

Billed Items

You are billed for the following items on a yearly/monthly basis.

**Table 1** Items billed on a yearly/monthly basis
Billing Item		Description
Edition		Edition of the purchased service
Extended package	Protected EIPs at Internet boundary	If you have purchased a yearly/monthly CFW edition, the extended package is also billed on a yearly/monthly basis.
	Peak protection traffic at Internet boundary
	Protected VPCs

Billed Usage Period

A yearly/monthly CFW instance is billed for the purchased duration. The billing starts when you activated or renewed the subscription (accurate to seconds), and ends at 23:59:59 of the expiry date.

For example, if you purchased a one-month CFW instance on June 30, 2023, 15:50:04, the billed usage period is from June 30, 2023, 15:50:04 to July 30, 2023, 23:59:59.

Billing Examples

Suppose you purchased a one-month CFW subscription on June 30, 2023, 15:50:04 (edition: professional; extended package: one added EIP, 5 Mbit/s peak protection traffic, and one added VPC). Billing resources include the professional edition and extended package (added EIPs, added peak traffic protection capacity, and added VPCs). Your subscription is one month and you manually renew the subscription for another month before the subscription expires. The billing details are as follows:

The first billing period is from 15:50:04 on June 30, 2023 to 23:59:59 on July 30, 2023.
The second billing period is from 23:59:59 on July 30, 2023 to 23:59:59 on Aug. 30, 2023.

You will be billed for both usage periods. CFW resources are billed individually as follows:

**Table 2** Formula
Product Information	Formula
Edition	Price of the purchased service edition x Required duration
Add EIP protection capacity	Unit price of expansion package for the protected public IP address x Number of protected public IP addresses x Required duration
Add peak traffic protection capacity	Unit price of expansion package for the peak protection traffic x Traffic x Required duration
Added VPCs	Unit price of VPC expansion package x Number of VPCs x Required duration

Figure 1 shows how the total price is calculated.

The prices in the figure are just examples. The actual prices are those displayed on CFW Pricing Details.

Price Change After Specification Change

If the specifications of yearly/monthly CFW resources 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 your CFW specifications, you need to pay the difference in price.

Suppose there is no discount for resource upgrade and you purchased a one-month standard edition CFW with one EIP and 5 Mbit/s peak traffic on June 8, 2023, and added one VPC on June 18, 2023. The price of the original specifications was $462 USD/month, and that for the new specifications was $1792 USD/month. The price difference will be calculated as follows:

Specification upgrade fee = New specification price × Remaining period - Old specification 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, Remaining period = 12 (Remaining days in June)/30 (Maximum number of days in June) + 8 (Remaining days in July)/31 (Maximum number of days in July) = 0.6581. Cost of upgrade = 1792 x 0.6581 - 462 x 0.6581 = $875.273 USD

Impact of Expiration

Figure 2 shows the statuses a yearly/monthly CFW can go through throughout its lifecycle. After CFW is purchased, it enters the valid period and runs normally during this period. If CFW 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 CFW subscription expires to remind you to renew the subscription.

Impact After Expiration

If your yearly/monthly CFW instance expires and is not renewed, after it expires, it changes to the Expired state and enters a grace period. During the grace period, you can access CFW.

If you do not renew your yearly/monthly CFW instance before the grace period ends, it goes into the retention period and its status turns to Frozen. You cannot perform any operations on such instances in the retention period.

If the yearly/monthly CFW resources are not renewed by the time the retention period ends, the CFW instance and protection configurations will be released and data cannot be restored.
