How Does NAT Gateway Pricing AWS Work?

NAT Gateway pricing AWS follows a straightforward model based on data transfer and usage. AWS charges for NAT Gateway usage in two primary ways: per-hour instance charges and per-GB data transfer charges. The hourly charge applies to each NAT Gateway provisioned in your account, regardless of whether it's actively transferring data. This ensures that you're only paying for the resources you've allocated, even during periods of low activity.

Data transfer charges, on the other hand, are based on the amount of data processed by the NAT Gateway. AWS bills these charges at a fixed rate per GB of data transferred. It's important to note that data transfer charges apply only to traffic originating from the private subnet and destined for the internet. Inbound traffic from the internet to the private subnet is not subject to these charges.
