What counts as egress?

Egress is data transferred out of a cloud region to the public internet or to other cloud providers. Traffic between services within the same region, or to the same-cloud CDN, is typically free or very low cost and is not modeled here.

Why does pricing change at 10 TB and 50 TB?

All three providers use tiered pricing where the first 10 TB/month is the most expensive bracket. Volumes above that threshold get lower per-GB rates. This calculator applies each tier correctly so large volumes are not over-estimated.

Are these real published prices?

Yes — rates reflect standard US-East internet egress list prices from each provider's public pricing pages. They do not include reserved capacity discounts, committed-use deals, or CDN pricing.

Why is GCP sometimes cheaper at high volumes?

GCP's egress tiers drop more aggressively beyond 10 TB ($0.06/GB) and beyond 150 TB ($0.05/GB). AWS and Azure have a smaller drop. At very high volumes GCP's rates can undercut the others.

Does this include CDN or CloudFront costs?

No — CDN egress has its own pricing (often lower). This calculator covers direct origin egress only. If you use a CDN you will typically pay less than the estimates shown here.

Rates are standard US-East internet egress list prices (no free tier, no reserved capacity, no CDN pricing). AWS: $0.09 / $0.085 / $0.07 / $0.05 per GB by tier. GCP: $0.085 / $0.06 / $0.05 per GB by tier. Azure Zone 1: $0.087 / $0.083 / $0.07 / $0.05 per GB by tier. Verify current rates at each provider's pricing page before making financial decisions.

Summary

Enter your monthly data transfer volume and cloud provider to estimate your egress bill based on published per-GB rates.

How it works

Enter your estimated monthly data transfer volume in GB or TB.
The calculator applies each provider's published tiered egress rates automatically.
Tiered pricing means the first 10 TB costs more per GB than the next 40 TB and beyond.
Results show a cost breakdown by tier for each provider side by side.
A savings summary highlights the cheapest provider for your volume.
Adjust the volume to model different traffic growth scenarios.

Use cases

Estimate the egress bill before launching a video streaming or file hosting service.
Compare providers when migrating a high-traffic API from one cloud to another.
Model egress cost at 2x or 5x traffic to plan for growth.
Understand how tiered pricing kicks in at the 10 TB and 50 TB boundaries.
Identify which provider is cheapest at your current transfer volume.
