Calculate and compare data egress costs across AWS, Azure, GCP, and OCI with tiered pricing breakdowns.
Last verified: May 2026
Output will appear here...The calculator walks each provider's published egress pricing tiers in order, applying the per-GB rate to the portion of your volume that falls in each tier. Internet, inter-region, and inter-AZ egress are calculated separately because their rates differ by 5-20x. Tier breakpoints, regional adjustments (egress from São Paulo or Tokyo costs more on every provider), and free tiers are encoded from each provider's pricing page at the verified date.
Egress is the cloud cost that surprises engineers most. The first terabyte is often free; the next ten terabytes are a few cents per gigabyte; cross-region and cross-cloud egress is multiples more expensive than internet egress on some providers. The Multi-Cloud Egress Cost Calculator applies the published tiered pricing for AWS, Azure, GCP, and OCI to your monthly transfer volume — separating internet, inter-region, and inter-AZ egress — so you can see where the bill actually goes before it arrives.
Your application generates 40 TB of monthly outbound traffic across two AWS regions and you have been quoted a private interconnect to a colo as 'cheaper than current AWS egress.' You run the numbers: at 40 TB on AWS, the egress bill is around $3,200/month after the volume discount kicks in. The private interconnect quote is $2,400/month plus port fees, breaking even at ~30 TB. Below that you would lose money on the interconnect; above 50 TB the gap grows fast. You wait until the next quarter when projected volume hits 60 TB, then sign.
S3 → CloudFront → end user is cheaper than S3 → end user for any non-trivial volume because CloudFront egress is priced lower than direct S3 egress and includes caching. The same pattern applies to Azure Blob → CDN and GCS → Cloud CDN.
Cross-region replication of an active database can quietly add thousands of dollars per month in egress. If your DR strategy depends on continuous replication, model the egress separately and compare it against snapshot-based replication.
GCP's standard tier internet egress is competitive with AWS, but their premium-tier (global Anycast) pricing is higher and that is what enterprises actually use. Where GCP wins consistently is inter-region within the same continent — much cheaper than AWS inter-region. The tool surfaces both numbers so the comparison stays honest.
Yes for the first-terabyte free tier on AWS, the 100 GB monthly internet egress free tier announced in 2021, GCP's free-tier networking, and OCI's 10 TB monthly free outbound. These materially change the answer for small workloads; for large workloads they are noise. Toggle them in the input to see both views.
