Frequently Asked Questions
How much does AWS Transit Gateway cost per month?
In us-east-1, a standard Transit Gateway attachment costs $0.05/hour, or about $36.50/month at 730 hours. VPC, VPN, Direct Connect gateway, and peering attachments all start from that hourly baseline in the lowest-cost regions, and you also pay $0.02/GB for supported data processed through the Transit Gateway.
What Transit Gateway traffic is charged at $0.02/GB?
AWS charges Transit Gateway data processing on traffic sent to the Transit Gateway for VPC, Site-to-Site VPN, and Direct Connect gateway attachments. This calculator models those direct Transit Gateway processing charges, but excludes adjacent charges like inter-Region transfer and other EC2/VPC data transfer fees.
Does Transit Gateway peering have data processing charges?
In the current public pricing model, peering attachments are billed hourly. This v1 calculator treats peering as hourly-only and does not add separate TGW peering data processing charges. Inter-Region transfer charges can still apply outside this calculator.
When is Transit Gateway cheaper than VPC peering?
For a small number of VPCs, VPC peering is usually cheaper because you avoid the fixed hourly attachment charge. Transit Gateway becomes attractive when you want centralized routing, simpler network operations, or many VPCs and hybrid connections in the same topology.
Who gets billed for Transit Gateway attachments?
Billing ownership depends on the attachment type. VPC attachments are billed to the VPC owner, VPN attachments to the Transit Gateway owner, and Direct Connect gateway attachments to the Direct Connect gateway owner. This calculator shows the total service cost only, not account-level attribution splits.
