NAT Gateway Pricing Calculator - Estimate AWS NAT Gateway Costs

A single NAT Gateway in us-east-1 costs $0.045/hour, which equals approximately $32.85/month (730 hours) for the hourly charge alone. You also pay $0.045 per GB of data processed. For a typical workload processing 100 GB/month, expect around $37.35/month total. Prices vary by region.

NAT Gateway data processing is charged for every GB that passes through the NAT Gateway, regardless of direction. In us-east-1, the rate is $0.045/GB. This is in addition to hourly charges and standard EC2 data transfer charges.

NAT Instance can be cheaper for low-traffic scenarios. A t3.nano NAT instance costs roughly $3.80/month versus $32.85/month for NAT Gateway. NAT Gateway provides higher bandwidth, automatic scaling, built-in redundancy, and no maintenance overhead.

Use Gateway VPC endpoints for S3 and DynamoDB, Interface endpoints for PrivateLink-supported services, single-AZ deployment for non-production workloads, andIPv6 egress-only internet gateways where possible.

For production high availability, AWS recommends deploying a NAT Gateway in each AZ where you have private subnets. For non-production workloads, a single NAT Gateway is often sufficient if you accept cross-AZ data transfer charges.

NAT Gateway supports up to 100 Gbps bandwidth and can handle up to 10 million packets per second. It scales automatically within these limits.
