AWS Egress Cost Calculator — Data Transfer Out
Estimate monthly AWS outbound data-transfer costs by scenario: internet egress, CloudFront delivery, or inter-region transfer. The calculator makes the modeled free tier and per-GB assumptions visible so you can compare them with your AWS bill.
Internet egress
Models outbound data sent from AWS to the public internet.
CloudFront comparison
Compare a CDN delivery scenario with direct internet egress.
Inter-region transfer
Estimate the separate cost of moving data between AWS regions.
Worked example: 1,000 GB leaving AWS in a month
For the modeled internet scenario, the first 100 GB uses the included allowance and the remaining 900 GB is charged at $0.09/GB. CloudFront and inter-region scenarios use their own rates instead of treating all outbound traffic as one bucket.
Planning estimates: $81 internet egress, $76.50 via CloudFront, or $20 inter-region before service-specific tiers.
How to use this estimate
- 1
Choose the traffic path
Select internet, CloudFront, or inter-region transfer based on where the bytes go next.
- 2
Enter monthly GB
Use outbound data only; downloads, replication, and CDN origin traffic can belong to different line items.
- 3
Compare with billing
Match the estimate against region, service, tier, and committed-use details in Cost Explorer.
What can change the result
Region and service
AWS transfer pricing varies by region, source service, destination, and direction.
Free tiers are scoped
The modeled first 100 GB allowance is a planning assumption, not a promise that every AWS service shares one pool.
Architecture changes cost
Caching, compression, replication, and multi-region design can move bytes between different pricing categories.
AWS pricing varies by service, region, tier, and contract. Use the official AWS pricing page and your billing console as the final source of truth.
Methodology & sources
This is an independent estimate. The calculator applies the rates shown in its breakdown; platform contracts, country, account tier, taxes, and promotions can change the final amount. Confirm the current terms before making a financial decision.
Rates and platform terms can change. Use the linked official source when available and verify the current terms before transacting.
