What does your cloud egress actually cost?

Egress is the third-largest line item on most cloud bills and the hardest to forecast because it scales with traffic, not architecture. This calculator runs the math against AWS, Azure, and GCP at current 2026 rates and shows what direct-connect would save you.

!
Why this exists: cloud egress doesn't appear in your architecture diagrams. A Kubernetes cluster spread across 3 AZs with 50 services chatting can quietly generate 10 TB of inter-zone traffic per month, billed at $0.01–0.02 per GB. Add cross-region replication and internet egress, and a "small" cloud deployment can hide $5K–$20K per month in pure network charges nobody budgeted.

Monthly Egress Volume

Total outbound data leaving your VPC / VNet / project per month.

Traffic Mix

How that egress breaks down. Internet is the most expensive; internal AZ-to-AZ is the cheapest.

To users, customers, APIs, anything outside the cloud.
Same cloud, different region (us-east-1 ↔ eu-west-1, DR replication).
Multi-cloud: data flowing AWS ↔ Azure ↔ GCP. Priced as internet egress.
Within-region cross-AZ. Cheapest but adds up at scale.

Share of internet egress that goes through a CDN. CDN egress is ~5% cheaper than origin egress.

→ Direct connect savings

Cut egress 50-80% with private connectivity

AWS Direct Connect, Azure ExpressRoute, GCP Cloud Interconnect, and Oracle FastConnect all bypass internet egress pricing. Here's what your traffic would cost on private circuits.

Note on direct-connect economics: circuit costs vary by port speed and location ($300-$3,000/month for 1-10 Gbps ports), and only traffic flowing over the circuit gets the discounted rate. The savings above apply to internet + cross-region egress only — inter-AZ stays at the same rate. For sustained high egress (10+ TB/month), direct connect typically pays for itself in 1-3 months.

Why Each Cloud Costs What It Does

Egress isn't a single rate — it's tiered by volume. Here's where your traffic lands.

▸ See pricing rates and methodology

All rates verified against official provider documentation as of April 2026. Prices may vary by region, contract term, and enterprise agreement. Cross-region rates assume same-continent transfer; cross-continent (e.g. us-east to ap-south) costs 2-4× more.

Other rates used

  • Cross-region: ~$0.02/GB AWS/Azure same-continent · ~$0.04/GB GCP (premium tier midpoint)
  • Inter-AZ: $0.01/GB each direction on AWS/Azure · $0 on GCP within region
  • CDN egress: ~5% discount vs origin (CloudFront $0.085 vs S3 $0.09)
  • Cross-cloud: priced identically to internet egress in all providers
  • Direct Connect (AWS): $0.02/GB egress port-side, replaces internet rate
  • ExpressRoute (Azure): ~$0.025/GB (Premium SKU), replaces internet rate
  • Cloud Interconnect (GCP): $0.02/GB, replaces internet rate

What this calculator does NOT include

  • NAT Gateway processing fees ($0.045/GB on AWS) — can be 50-100% of egress for some architectures
  • VPC PrivateLink charges
  • Direct Connect / ExpressRoute / Interconnect port fees (the monthly circuit cost)
  • S3 Transfer Acceleration premiums
  • Cross-continent surcharges (Asia, South America, Middle East)
  • Per-request fees on object storage (small but add up at billions of requests)
