The NAT Gateway Tax
At low traffic (10 GB/month), your effective cost per GB is ~$3.33 — the fixed hourly charge dominates. At 1 TB/month, the effective cost drops to ~$0.08/GB. The NAT Gateway is most cost-effective at high throughput. For low-traffic workloads, a NAT Instance or VPC Endpoints can save 80-90%.
The Essentials
Two Charges
Per-hour ($0.045) + per-GB ($0.045) in us-east-1
Up to 100 Gbps
5 Gbps base, auto-scales to 100 Gbps
Per-AZ Deployment
One NAT Gateway per AZ for redundancy
Hidden Data Costs
Cross-AZ transfer adds $0.01/GB on top
Fully Managed
No patching, scaling, or failover to manage
NAT Instance Alternative
t4g.nano at ~$3/mo but self-managed
