Outbound data transfer refers to data that flows from Alibaba Cloud networks to the ports or virtual border routers (VBRs) that are associated with your data center. This topic describes the billing rules for outbound data transfer.
Overview
Item | Rule |
Billing cycle and bill generation time | If you use the service for less than 1 hour, the usage duration is rounded up to 1 hour. In most cases, bills are generated within 1 hour after a billing cycle ends. The time it takes for bills to be generated is determined by the system. |
Billable item and billing formula | You are charged for outbound data transfer in all regions within your Alibaba Cloud account. The outbound data transfer fee for a region is calculated by using the following formula:
|
Deduction rule for outbound data transfer fees | If you deploy Express Connect circuits in multiple regions within an Alibaba Cloud account, the amount of outbound data transfer in the region where you create connections over Express Connect circuits first are offset by the free quota and then the remaining data transfer are billed. |
Usage notes
In addition to the billing for outbound data transfer, the following changes are made to the billing for Express Connect:
You are no longer charged an initial installation fee of USD 1,500 for an Express Connect circuit. This reduces the costs of connecting data centers to Alibaba Cloud.
You can create additional VBRs free of charge to meet the requirements of complex networking.
You are not charged for data transfer from your data centers to Alibaba Cloud. You are charged only for data transfer from Alibaba Cloud to your data centers. This reduces the cost of data transfer when you use an Express Connect circuit to connect to Alibaba Cloud.
Alibaba Cloud provides an outbound data transfer quota for each Alibaba Cloud account. After you enable billing for outbound data transfer, you can use 50 TB of outbound data transfer free of charge each month until the end of December 31, 2024. Starting January 1, 2025, you are charged for all of the outbound data transfer in your service based on the billing rules. For more information, see Enable billing for outbound data transfer.

Enable billing for outbound data transfer
Before you enable billing for outbound data transfer, make sure that your Alibaba Cloud account completes real-name registration. For more information about real-name registration, see FAQ about real-name registration on the Alibaba Cloud international site (alibabacloud.com) .
If you use a Resource Access Management (RAM) user, make sure that you are granted the
AliyunExpressConnectFullAccesspermission or thevpc:OpenPhysicalConnectionServicepermission.
Log on to the Express Connect console
In the top navigation bar, select a region and click Physical Connection in the left-side navigation pane.
In the Enable Outbound Data Transfer Billing section, click Enable Now.
On the page that appears, read and agree to Terms of Service and click Activate.
Example of outbound data transfer fees
You have two data centers. One is located in the China (Beijing) region and the other is located in the US (Virginia) region. You want to use an Express Connect circuit to connect the data center in the China (Beijing) region to an Elastic Compute Service (ECS) instance in a virtual private cloud (VPC) that is deployed in the same region. You also want to connect the data center in the US (Virginia) region to an ECS instance in a VPC that is deployed in the same region. After you use the same Alibaba Cloud account to establish connections over Express Connect circuits in the preceding regions, data is transmitted from Alibaba Cloud to the data centers. 100 TB of outbound data is transferred in the China (Beijing) region and 80 TB of outbound data is transferred in the US (Virginia) region per month.
Before the free quota of outbound data transfer expires, the outbound data transfer fee that you must pay each month is calculated by using the following formulas:
China (Beijing): USD 0.0125 per GB × (100 - 50) × 1,024 GB = USD 640
US (Virginia): USD 0.0190 per GB × 80 × 1,024 GB = USD 1,556.48
Total fee = USD 640 + USD 1,556.48 = USD 2,196.48
After the free quota of outbound data transfer expires, the outbound data transfer fee that you must pay each month is calculated by using the following formulas:
China (Beijing): USD 0.0125 per GB × 100 × 1,024 GB = USD 1,280
US (Virginia): USD 0.0190 per GB × 80 × 1,024 GB = USD 1,556.48
Total fee = USD 1,280 + USD 1,556.48 = USD 2,836.48
