VPC Pricing Calculator - Public IPv4, Endpoints, Peering & IPAM

As of February 2024, AWS charges $0.005 per hourfor all public IPv4 addresses, whether they're in-use or idle. This applies to EC2 instances, Elastic IPs, ELB, RDS, NAT Gateways, and other services. At 730 hours/month, that's approximately $3.65/month per IP. You can bring your own IP addresses (BYOIP) at no charge. Consider using IPv6 where possible to avoid these costs.

Interface endpoints (PrivateLink) cost approximately $0.01 per AZ per hour plus data processing charges of $0.01/GB for the first 1 PB. Gateway endpoints for S3 and DynamoDB are free - no hourly or data processing charges. Use gateway endpoints whenever possible to reduce costs. For a single interface endpoint across 2 AZs, expect around $14.60/month plus data charges.

VPC Peering data transfer within the same Availability Zone is free. Cross-AZ data transfer within the same region is charged at $0.01/GB in both directions (so $0.02/GB total for round-trip). Cross-region peering uses standard EC2 data transfer rates, which vary by region pair.

Traffic Mirroring costs $0.015 per ENI per hourfor each network interface with mirroring enabled. That's approximately $10.95/month per ENI. You continue to be charged until you delete the traffic mirror session - stopping the EC2 instance doesn't stop the charges. Plan your mirroring sessions carefully and clean up unused sessions.

IPAM Free Tier is available for managing IPs in a single region and account at no cost. It includes BYOIP management, Public IP Insights, and IPv6 management. IPAM Advanced Tier for multi-region/multi-account scenarios costs $0.00027 per active IP per hour (about $0.20/month per IP). Only IPs attached to running resources are counted as active.

Amazon-provided Contiguous IPv4 Blocks give you sequential public IPv4 addresses for security allowlisting needs. They cost $0.008 per IP per hour(higher than regular public IPs). A /28 block (16 IPs) costs about $92/month. You're charged for all IPs in the block from provisioning, regardless of whether they're attached to resources.
