# Data Transfer

Data Transfer is a pay-per-gigabyte billing method with an optional prepaid package. You select a monthly volume in TB, and any usage beyond the package is billed as overage. An optional bandwidth cap limits the maximum throughput.

For a detailed guide on how Data Transfer billing works, when to use it, and how it compares to other billing methods, see the [Data Transfer Billing](/welcome/elastic-compute/networking/01-overview/03-data-transfer.md) documentation.
