Amazon Transit Gateway pricing

In Amazon 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 Amazon Transit Gateway. You can create a Transit Gateway to connect to multiple Amazon Virtual Private Clouds (Amazon VPCs), Direct Connect, and Software-Defined Wide Area Network (SD-WAN) appliances, and that Transit Gateway can work across accounts. The VPC account owner is billed hourly for each hour that their Amazon VPCs are attached to an Amazon Transit Gateway.

For Amazon Direct Connect attachments, the Direct Connect Gateway owner is billed hourly. For Transit Gateway Connect attachments (SD-WAN appliances), the Transit Gateway owner is billed hourly. For peering attachments, each Transit Gateway owner is billed hourly for the peering attachment with the other Transit Gateway.

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.

Data processing charges apply for each gigabyte sent from a VPC or Direct Connect to the Amazon Transit Gateway. There are no additional data processing charges for Transit Gateway Connect other than those applied to the underlying VPC or Direct Connect attachment. Data processing charges also apply to each gigabyte received by each multicast receiver instance. Data processing charges do not apply for data sent from a peering attachment to a Transit Gateway.
