Egress Exposure Calculator

An Excel calculator for cloud egress cost, the break-even for a dedicated link, and a 12-month projection.

First page of Egress Exposure Calculator

What's inside

  • Five inputs: monthly data-out volume in TB, egress rate per GB, dedicated link monthly cost, projection horizon and annual data growth.
  • Pay-as-you-go egress cost per month and per year, with and without growth.
  • The data volume at which a dedicated interconnect costs less than pay-as-you-go, with a yes/no verdict and the annual saving.
  • A month-by-month projection with cumulative cost for both options.
  • A 2-page PDF guide: what egress cost is, how to use the calculator in four steps, a worked example at 50 TB a month, and five costs the calculator leaves out.

Format: PDF (2 pages) and Excel workbook.

How to use it

Run it before committing to a provider or region, or when deciding whether a dedicated interconnect pays back.
