How we calculate your bill

We bill you monthly according to that month's use of Fastly's services. Your bill 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 shielding or compression).

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.


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.

About the monthly minimum charges

We bill a minimum of $50 per month so we can fully support all of our customers. This is the minimum price you'll pay in any month once you've completed your testing trials.

For example, say that you're done testing Fastly's services and you've begun to push production-level traffic through Fastly. If most of your site's traffic for the current month is in North America and Europe and your site uses 10GB of traffic over 10 million requests, the combined bandwidth and request charges would be $8.70 for the month. Because this amount falls below the $50 monthly minimum (you'll see this appear as a "commit shortfall" on your bill), we would charge you $50 for that month, not $8.70.

Bandwidth and request prices for some billing regions are slightly higher. If most of your site's traffic were in these other regions instead, then at the above traffic levels your bandwidth and request usage charges would still fall below the monthly minimum and we would charge you $50 for that month.


If you're using Fastly for content delivery via Heroku's cloud development services, see Heroku's add-ons pricing plan for additional details.

When we charge you for Fastly services

Fastly bills in arrears, not in advance, meaning that we bill you for services after you've used them, not before. For example, if you sign up for and start using Fastly services in January, the bill you receive in February reflects January's charges and services, your March bill reflects February's charges and services, and so forth.

How account cancellation affects your bill

If you ever cancel your account, you'll be billed for any outstanding charges accrued through the day you canceled, or at least the monthly minimum, whichever amount is greater.

Estimating your month-to-date bill

You can estimate your month-to-date (MTD) bill via the web interface or via the API.

Via the web interface

To view an estimated report of account usage for the current partial month, use any standard web browser to log in to your Fastly account and navigate to:


A small number of billing plans cannot be calculated month-to-date and only include an end-of-month generated invoice. If you have one of these billing plans, the web interface will clearly tell you that you can’t see the report due to your account’s status.

Via the API

As part of our API, a billing endpoint exists to generate a report of your usage for the current partial month (known as month-to-date, or MTD). Full details of this endpoint's output format can be found in our Billing API documentation. Generating a report via API usually takes only a few seconds, but can potentially take up to 60 seconds. During this time, the API call will return an HTTP 202 Accepted response.
