Egress pricing is where cloud bills surprise people. Data going in is usually free and data coming out is charged, often at a rate that makes moving a large dataset cost more than storing it for a year. The effective cost per gigabyte is the figure to compare across plans, because a low headline price with a small allowance frequently works out dearer than a higher one with generous inclusions. Content delivery networks and caching change this calculation entirely by serving repeated requests without touching origin egress. For anything served repeatedly, that is usually a larger saving than negotiating the rate.
How the Data Transfer Cost Calculator works
Monthly and annual cost of data transfer, separating the included allowance from overage. The effective cost per gigabyte is the figure that actually compares plans.

Frequently asked questions
Why is cloud egress so expensive?
Because it is priced as a product rather than a cost. Data going in is usually free and data coming out is charged, often at a rate that makes moving a dataset cost more than storing it for a year.
How do I compare data plans?
On effective cost per gigabyte at your actual usage. A low headline price with a small allowance frequently works out dearer than a higher one with generous inclusions.
How do I reduce egress costs?
Caching and a content delivery network, which serve repeated requests without touching origin egress. For anything served repeatedly that saves far more than negotiating the rate.
What counts as egress?
Data leaving the provider's network — to users, to another region, and often to another provider. Traffic within the same region and availability zone is usually free or much cheaper.
Are overage rates worse than the base rate?
Frequently, and sometimes by a lot. That is what makes the next tier up worth checking whenever you are regularly over — the calculator flags it when you are.
