In AWS Transit Gateway you are charged for the number of connections that you make to the Transit Gateway per hour and the amount of traffic that flows through AWS Transit Gateway. You can create a Transit Gateway to connect to multiple Amazon Virtual Private Clouds (Amazon VPCs), Direct Connect and VPNs, and that Transit Gateway can work across accounts. The VPC account owner is billed hourly for each hour that their Amazon VPCs attached to an AWS Transit Gateway.
For AWS VPN attachment, the Transit Gateway owner is billed hourly for VPN attachments. For AWS Direct Connect attachment, the Direct Connect Gateway owner is billed hourly for Direct Connect attachment.
Hourly billing will also start when the Transit Gateway owner accepts your VPC and it stops when the attachment is deleted. Each partial VPC Transit Gateway hour consumed is billed as a full hour. Similarly, a VPN attachment will be charged hourly.
AWS Site-to-Site VPN connection pricing still applies in addition to AWS Transit Gateway VPN attachment pricing. Please see the product page for AWS Site-to-Site VPN pricing.
Data processing charges apply for each gigabyte sent from a VPC, Direct Connect or VPN to the AWS Transit Gateway.
