FAQ

Does this include inter-region or CDN costs?

No. Add those separately—this focuses on outbound egress from the origin region.

How should I set the markup?

Use your provider's 95th percentile factor or any premium applied for burst windows or specific destinations.

Can I convert GB to TB?

Enter the GB value directly. If you have TB, multiply by 1,024 to convert to GB before using the calculator.
