How we calculate your delivery bill
Last updated 2023-12-12
Your bill for content delivery and streaming delivery services is affected by a combination of things including the actual traffic Fastly has served on your behalf, the products you've purchased, the features you've enabled, and the specific configuration settings you've chosen (like enabling compression).
NOTE
Billing limits for this product may be different if you've purchased a packaged offering or are using a product or feature trial.
We charge for egress traffic from our POPs, including traffic served to end users and, if shielding is enabled, traffic served from the shield POP to other POPs. Specifically, we charge for each response and for the size of the response (which includes the header and body). Each response is billed as a single request, and the response size in bytes is billed as bandwidth. We charge for bandwidth and requests for content delivered to clients from the CDN and for bandwidth for traffic sent from the CDN to our customers' origins.
NOTE
If you're using Anycast IP addresses, these IPs use our global network and will route a request to the nearest POP located in a billing region that may charge a higher rate. Our billing regions can be found on the Fastly Pricing page. We announce new billing regions regularly via our service status page.
Charges for any options you've chosen are applied in addition to the bandwidth and request usage we charge for normal content delivery and streaming and may be adjusted according to any packaged offering you've purchased. In accordance with local laws, Fastly may also collect sales tax based on your shipping or billing address on file.
About the measurements and calculations we use
We measure months according to Coordinated Universal Time (UTC). For usage-based charges, bandwidth is recorded in bytes and presented in gigabytes (GB), and requests are recorded individually and presented in units of 10,000.
Fastly uses The International System of Units (SI Units) to measure bandwidth. In our calculations, 1 gigabyte (GB) = 109 (1,000,000,000) bytes, 1 terabyte (TB) = 1012 bytes (or 1,000 GB), and 1 petabyte (PB) = 1015 bytes (or 1,000 TB). Your invoice shows your usage and that matches the usage shown on the Observability page.
