Transit Gateway Pricing for various environments that I have

Question

Hi there,
I am planning to create a Transit gateway and there would be 5 VPCs which I will be attaching to the Transit Gateway. What would be the pricing of the transit gateway in that case?

Accepted Answer

AWS Transit Gateway Charges you, here is the calculation for TGW Attachment for 5 VPCs as I assume that you would be having at least 5 attachments in that case.

```
Price per AWS Transit Gateway attachment ($)	$0.07
Price per GB of data processed ($)	$0.02
```
```
730 hours in a month x 0.05 USD = 36.50 USD (Transit Gateway attachment hourly cost)
1 GB per month x 0.02 USD = 0.02 USD (Transit Gateway data processing cost)
36.50 USD + 0.02 USD = 36.52 USD (Transit Gateway processing and monthly cost per attachment)
5 attachments x 36.52 USD = 182.60 USD (Total Transit Gateway per attachment usage and data processing cost)
Total Transit Gateway per attachment usage and data processing cost (monthly): 182.60 USD
```
Along with that you will be paying for the Data Processing as well with 0.03 USD/GB. Please note that the pricing may vary based on the AWS Region that you will select.
