Cloud Egress Cost Calculator
Enter your monthly data transfer volume to calculate exact egress costs across all major cloud providers. The calculator applies tiered pricing automatically, deducts free tier allowances, and shows you a per-tier breakdown so you can see exactly where your money goes. Switch between AWS, Azure, and GCP or compare all providers side by side.

How the Calculator Works
Tiered Pricing
Cloud providers charge different rates based on your monthly volume. The first few TB are the most expensive. As your volume increases, the per-GB rate decreases. Our calculator applies each tier sequentially, just like your actual cloud bill.
Free Tier Deduction
AWS and Azure both provide 100 GB/month of free internet egress. GCP provides similar allowances. The calculator automatically deducts these free allowances before calculating billable data transfer, giving you the actual cost you would see on your invoice.
US Region Pricing
All calculations use standard US-region internet egress rates. Azure Zone 2 and Zone 3 regions, GCP Asia/Australia regions, and premium networking tiers may have different rates. Check the provider-specific pages for regional pricing details.
What This Calculator Does Not Include
This calculator focuses on standard internet egress pricing. Several additional data transfer charges are not included but can significantly impact your total bill. Be aware of these costs when planning your architecture:
NAT Gateway processing
AWS charges $0.045/GB for data processed through NAT Gateways, on top of standard egress. Learn more
Cross-AZ transfer
AWS charges $0.01/GB each way for cross-AZ data transfer. This is invisible on most bills but adds up fast. Learn more
Negotiated discounts
Enterprise customers on AWS EDP, Azure MACC, or GCP CUDs may have lower rates than published pricing. Learn more
Service-specific charges
Some services like API Gateway, Load Balancers, and CloudFront have their own data processing fees in addition to egress. Learn more
Frequently Asked Questions
How do I calculate my cloud egress costs?
Enter your monthly data transfer volume in GB, TB, or PB into our calculator. Select your cloud provider (AWS, Azure, or GCP) or compare all at once. The calculator applies tiered pricing automatically, showing you the exact monthly and annual cost including the free tier deduction.
What does the egress calculator include?
The calculator covers standard internet egress pricing for AWS (S3, EC2, ECS, Lambda), Azure (Blob Storage, VMs, App Service), GCP (Cloud Storage, Compute Engine), Cloudflare R2, Backblaze B2, and Wasabi. It applies tiered pricing, deducts free tier allowances, and shows per-tier breakdowns.
How accurate is this calculator?
The calculator uses official published pricing from each provider's documentation, verified as of March 2026. It calculates standard internet egress from US regions. Actual costs may vary based on specific services, regions, negotiated discounts, and special pricing programs.
Does the calculator account for free egress allowances?
Yes. AWS and Azure both provide 100 GB/month of free internet egress, and GCP provides similar free tier allowances. The calculator deducts these free allowances before calculating billable data transfer costs.
