Cloud Egress Cost Calculator

About this calculator

Cloud providers like AWS, Google Cloud, and Azure generally charge nothing for data flowing into their network (ingress), but bill for data flowing out to the public internet or across regions — this is egress. Egress cost is calculated as the volume of data transferred in gigabytes multiplied by the provider’s per-GB rate, though most providers apply tiered pricing where a certain amount is free each month and the per-GB rate drops at higher volumes.

DevOps engineers and cloud architects budget for egress specifically because it is one of the most common sources of surprise cloud bills — data-heavy applications like video streaming platforms, backup services, and APIs serving large payloads to many users can rack up egress charges that dwarf compute costs, and multi-region or multi-cloud architectures that move data between regions or providers incur egress fees that a single-region setup would avoid entirely.

Enter the gigabytes you expect to transfer and the per-GB price, and this calculator estimates your egress cost before the bill arrives.
