What Is VPC Peering Cost?
VPC peering cost refers to the financial implications of establishing and maintaining a peering connection between two or more Virtual Private Clouds (VPCs) within AWS. While AWS does not impose any charges for creating or maintaining the peering connection itself, the costs primarily arise from data transfer. Data transfer pricing depends on the regions involved and the volume of data exchanged, making it essential to understand the underlying pricing model.
Data transfer costs are calculated based on the amount of data transferred out of a VPC to another peered VPC. For instance, transferring data within the same AWS region is typically free, but transferring data between regions incurs charges. These charges vary depending on the specific regions involved and the data transfer volume. Additionally, data transfer costs can be influenced by factors such as the type of data being transferred, the frequency of transfers, and the overall architecture of your cloud environment.
Understanding VPC peering cost is critical for businesses aiming to optimize their cloud infrastructure expenses. By carefully analyzing and managing data transfer patterns, organizations can significantly reduce their VPC peering-related expenses, ensuring that their cloud investments yield maximum value.
How Does AWS Charge for VPC Peering?
AWS employs a straightforward pricing model for VPC peering, focusing primarily on data transfer costs. The peering connection itself is free to establish and maintain, but any data transferred between peered VPCs incurs charges. These charges are determined by the regions involved and the volume of data transferred.
For intra-region data transfers (data moving between VPCs within the same AWS region), AWS generally does not impose any charges. However, inter-region data transfers (data moving between VPCs in different AWS regions) are subject to fees. These fees are calculated based on the distance between the regions and the volume of data transferred. AWS provides detailed pricing information on its official website, allowing users to estimate their potential costs accurately.
To better manage VPC peering cost, AWS offers tools such as Cost Explorer, which enables users to monitor and analyze their data transfer expenses. By leveraging these tools, organizations can gain valuable insights into their usage patterns and identify opportunities for cost optimization.

How Much Does VPC Peering Cost?
The actual VPC peering cost varies depending on several factors, including the regions involved, the volume of data transferred, and the specific pricing tiers applicable to your account. For intra-region transfers, AWS typically does not charge for data transfer between peered VPCs. However, inter-region transfers can incur significant costs, especially for large-scale data exchanges.
As of the latest pricing updates, inter-region data transfer costs range from $0.02 to $0.08 per GB, depending on the regions involved. For example, transferring data between US East (N. Virginia) and EU (Ireland) costs $0.02 per GB, while transferring data between US East (N. Virginia) and Asia Pacific (Tokyo) costs $0.08 per GB. These costs can add up quickly for organizations with extensive cross-region data exchange requirements.
To estimate your VPC peering cost, it's essential to consider your data transfer patterns and the regions involved. AWS provides a pricing calculator that allows users to input their specific usage details and obtain accurate cost estimates. By utilizing this tool, businesses can better plan and budget for their VPC peering expenses.
