Count delivery bytes and viewer requests separately
A CloudFront pay-as-you-go delivery estimate needs both outbound data and request volume. A site serving many tiny responses can have a different cost profile from a site sending a few large files, even if the total bytes match.
Select the applicable pricing model and delivery geography before using the estimate. The calculator focuses on US edge-location pay-as-you-go data transfer and HTTPS requests; it is not a quote for every geography or a comparison of flat-rate plans.
Worked example: a static website
Suppose a website serves 500,000 page visits during a month. A hypothetical measured visit downloads 1.2 MB across 12 HTTPS requests. The initial estimate is 600,000 MB of transfer and six million requests.
Using decimal units for the teaching example, that is 600 GB. If average downloaded payload rises to 2 MB while requests per visit stay constant, transfer becomes 1,000 GB but requests remain six million. If page requests instead rise to 20 at the original payload size, requests become ten million while bytes remain at the original estimate.
Those scenarios isolate two different drivers. Convert byte totals into the calculator’s stated unit, then enter request millions in its request field. Apply the tool’s displayed allowance once; do not subtract it manually before entering usage if the calculator already handles it.
Use observed transfer size
Browser caching, compressed responses, repeat visits, bots, and failed requests all influence actual traffic. Page asset size is a starting point rather than a billing measurement. Use delivery logs or metrics to check the average bytes and requests per visit.
The focused subtotal omits later transfer tiers, invalidations, origin activity, edge compute, and other optional services. The annual display repeats the monthly scenario; a launch spike or seasonal campaign should be modeled separately.
Frequently asked questions
Does a small page always have a small CloudFront bill? High request volume can still matter, so model both dimensions.
Can I apply the US calculator to a global audience? Only to the applicable US delivery portion. Build a geographically appropriate estimate for the remaining audience and check the selected plan’s terms.
Calculate your scenario
Use the cloudfront cost calculator. Keep the displayed region, pricing date, billing units, and exclusions alongside your result. The arithmetic examples above illustrate usage or explicitly hypothetical rates; they are not AWS quotes.
