On published price lists checked August 2026, 100 TB of monthly delivery costs $415 on BlazingCDN and $6,965 on the Amazon CloudFront pay-as-you-go rate card for transfer alone. The billing model, more than the headline per-GB rate, explains most of that gap. This brief compares the six CDN pricing models: per GB, volume tiers, commits, flat rate, feature add-ons and reseller. It then works the math at 10 TB, 100 TB and 1 PB a month and ends with a checklist for reading a quote before you sign. - **Commit break-even:** a commit at a 30 percent discount only beats pay-as-you-go if you use at least 70 percent of the committed volume. - **Small volumes:** below about 46 TB a month, flat plans such as Amazon CloudFront Business ($200 for 50 TB) or Cloudflare Pro ($25 a month) can cost less than any metered per-TB rate. - **Request fees:** 100 TB of 50 KB images is 2 billion requests. At an illustrative $0.01 per 10,000 requests, that adds $2,000 to the month. ## **How content delivery network pricing works: the six CDN pricing models** Every CDN invoice comes down to three inputs: the bytes delivered, the requests served and the features switched on. The model decides how those inputs turn into dollars and who carries the risk when traffic moves. | Model | How the bill is computed | Fits | Main risk | | --- | --- | --- | --- | | Pay-as-you-go per GB | Metered bytes times a rate, often with regional multipliers and request fees | Unpredictable, seasonal or early-stage traffic | A traffic spike becomes a billing spike | | Volume tiers (progressive or blended) | Rate falls as monthly volume rises | Growing, high-volume delivery | Blended tiers create cliffs; region tables hide the real rate | | Committed volume | Discounted rate for a monthly or annual minimum | Stable, forecastable baselines | Paying for unused volume; true-ups at renewal | | Flat rate | Fixed monthly fee, sometimes with a bundled traffic allowance | Small and mid-size sites, budget certainty | Fair-use limits, throttling or forced upgrades | | Feature-based add-ons | Delivery plus separate lines for image optimization, edge compute, security, logs, support | Teams that need a few specific capabilities | Invoice sprawl; add-ons can exceed delivery cost | | White-label or reseller | Wholesale commit resold under the reseller's brand | Agencies, hosting companies, telecom operators | Margin depends on filling the wholesale commit | The model that fits your traffic shape matters more than the lowest per-GB rate on any single line. ### Progressive vs. blended tiers Progressive tiers work like tax brackets: each rate applies only to the traffic inside its band, so the monthly total always rises smoothly with volume. Blended tiers bill the whole month at the rate of the band you reach. That creates cliffs where 99 TB can cost more than 101 TB, which rewards pushing traffic over a boundary and punishes landing just under it. ### The commit break-even rule A commit pays off only when actual usage exceeds the committed volume multiplied by the commit rate divided by the pay-as-you-go rate. At a 30 percent discount, that is 70 percent utilization. At 20 percent, it is 80 percent. Size commits to your trailing 90-day minimum, not to your average, and never to your peak. ## **What CDN pricing looks like in published price lists (August 2026)** Published CDN pricing for North America and Europe runs from about $2.50 per TB at high volume to more than $100 per TB at entry volumes, on price lists checked August 2026. Most vendors discount with volume. Many charge more for Asia, South America and Oceania, and some add per-request fees on top. Convert every quote to effective cost per delivered GB before comparing. The $415 BlazingCDN month at 100 TB is $0.00415 per GB. The $6,965 CloudFront pay-as-you-go month is about $0.07 per GB. The Fastly published rate card reaches about 20 TB, where the month costs $2,087, or roughly $0.10 per GB. Akamai publishes no CDN price list. Cloudflare Enterprise is widely reported to start near $5,000 a month. ## **Content delivery network cost at 10 TB, 100 TB and 1 PB a month** ### 10 TB a month: flat plans often win At this volume a metered rate is rarely the cheapest option. Cloudflare Pro at $25 a month and Amazon CloudFront Business at $200 for up to 50 TB are both published flat plans, as checked August 2026. On metered pricing, BlazingCDN comes to $47.50 (5 TB at $5 plus 5 TB at $4.50). Published per-GB rates put bunny.net at about $50 on its Volume network and $100 on Standard. CloudFront pay-as-you-go comes to roughly $765 after its 1 TB allowance (our estimate from the same rate card). At 10 TB, the deciding question is what the flat plan's fair-use terms allow, not the metered rate. ### 100 TB a month: where the models diverge | Vendor | Cost at 100 TB/month | Billing model | Strength | Honest limitation | | --- | --- | --- | --- | --- | | BlazingCDN | $415 | Progressive tiers, one global rate, no request fees | NVMe SSD servers, onboarding in about one hour | No HTTP/3 or WebSockets; no WAF or DDoS mitigation | | bunny.net | $500 Volume, $1,000 Standard | Per GB, network tier chosen per zone | Broad self-serve add-on catalog | The $500 price uses the smaller Volume network | | CDN77 | $990 | Plan covering up to 250 TB | Predictable monthly figure | At 100 TB the effective rate is $9.90 per TB | | Amazon CloudFront | From $1,000 Premium flat; $6,965 pay-as-you-go | Flat plans or regional per-GB plus request fees | Deep AWS integration, security bundled in flat plans | Pay-as-you-go adds regional rates and per-request charges | | Gcore | About EUR 2,000 at list | Plan-based, negotiated at volume | Wide edge platform beyond delivery | List price is a starting point for negotiation | | KeyCDN | $2,600 NA and Europe; $5,200 into Asia | Per GB by region, no contract | Simple self-serve billing | Asian traffic doubles the bill at this volume | At 100 TB a month on published price lists checked August 2026, the cheapest and the most expensive delivery-only options differ by more than 12x for the same bytes. BlazingCDN publishes this blog, so verify this ranking on your own traffic; the 14-day testing period exists for exactly that. As of September 2026, BlazingCDN bills on progressive marginal tiers from $5 per TB down to $2.50 per TB at volume, with one rate for the US, Europe and Asia and no request fees: 100 TB costs $415 and 1,000 TB costs $3,315. Current rates are on the [**BlazingCDN pricing page with the full tier table**](https://blazingcdn.com/pricing/). ### 1 PB a month: commit territory At 1,000 TB almost every buyer negotiates, so list prices set the ceiling rather than the deal. Run through the published CloudFront pay-as-you-go tiers, 1 PB comes to roughly $38,965 for transfer alone (our estimate, before private pricing). BlazingCDN lists $3,315 at 1,000 TB as of September 2026. Above 500 TB its Enterprise X plans are individually quoted, with discounts of up to 60 percent against entry pricing. At this scale, compare contract flexibility and true-up terms alongside rate. The detailed [**BlazingCDN vs Amazon CloudFront cost comparison**](https://blazingcdn.com/vs/aws-cloudfront/) walks through the same volumes line by line. ## **Effective cost per delivered GB: the line items that move the bill** The headline rate covers only bytes. These lines decide whether the invoice matches the spreadsheet: - **Request fees.** Object size drives them. 100 TB of 50 KB images is 2 billion requests, or $2,000 at an illustrative $0.01 per 10,000. The same 100 TB as 1 GB installers is 100,000 requests, which rounds to zero. - **Regional multipliers.** Traffic into Asia, South America, Oceania or Africa often bills at 1.5x to 3x the North American rate on regional price cards. - **Origin egress.** Your cloud bills every cache miss. At a 90 percent hit ratio, 100 TB of delivery pulls 10 TB from origin. At 96 percent, it pulls 4 TB. At typical cloud egress of $0.05 to $0.09 per GB, that gap is worth roughly $300 to $540 a month (estimate). - **Origin shield and request coalescing**, when sold as an add-on. - **Edge compute, image processing and log delivery**, often billed per invocation, per transformation or per GB of logs. - **Security bundles.** WAF, DDoS mitigation and bot management carry separate fees on most platforms. - **Support tiers and minimum monthly spend**, which set the floor of the invoice regardless of traffic. ## **Best fit by workload: a pricing-model decision matrix** | Workload | Traffic shape | Best-fit model | Check before signing | | --- | --- | --- | --- | | Media and streaming | High, steady volume; large segments | Progressive per-TB tiers, or a commit at baseline | Storage, DRM, transcoding and live features billed apart | | SaaS web apps and APIs | Small objects, many requests | Flat plan or per-GB without request fees | Request pricing; which security features are bundled | | Software downloads and updates | Large files, release-day bursts | Pay-as-you-go progressive tiers | Overage penalties, burst caps, per-object size limits | | Gaming builds and patches | Launch spikes far above baseline | Baseline commit plus metered overflow, or pure metered | Commit sized to the quiet months, not launch week | | Enterprise, multi-product | Mixed; security and compliance needs | Negotiated annual commit | True-up terms, cost reporting, exit clauses | | Agencies, hosts, telecom operators | Aggregated customer traffic | White-label wholesale commit | Margin at realistic utilization, branding rights | | Sites under about 46 TB a month | Modest, mostly web traffic | Published flat plan | Fair-use wording and upgrade triggers | Traffic volatility and object size, not industry label, should pick the pricing model. ## **Checklist for reading a CDN quote** 1. Convert every line to effective dollars per delivered GB at your trailing 90-day volume. 2. Confirm whether tiers are progressive or blended, and model the month just below each boundary. 3. List every region with its own rate and apply your real geographic traffic split. 4. Price requests from your actual object-size distribution, not an average. 5. Ask what happens above the commit or the plan allowance: overage rate, throttling or forced upgrade. 6. Find the minimum monthly spend and any setup fee. 7. Separate delivery from add-ons: shield, image processing, logs, security, support. 8. Read contract length, auto-renewal and true-up clauses. 9. Estimate origin egress at the hit ratio the vendor can show on your traffic. 10. Check the exit path: how fast you can shift traffic away, and what it costs. ## **Contract risk, switching cost and where pricing is heading** The expensive mistakes are contractual, not per-GB. Annual commits sized to a peak quarter, auto-renewals without a usage review and bundles that make security depend on the delivery contract all raise switching cost. The cheapest insurance is architectural: keep a second CDN behind DNS with a weighted split, so a renewal is a negotiation rather than a migration. BlazingCDN can run in that second-CDN role for heavy files while an existing provider keeps security and dynamic traffic. Pricing is drifting in two directions at once. Flat bundles that include security are spreading at low volumes, while metered per-TB rates keep falling for high-volume static delivery. This blog's call: hyperscaler CDNs will still charge per request on pay-as-you-go plans through the end of 2027, so small-object workloads should keep request counts in every cost model. ## **FAQ: Content Delivery Network Pricing and Contracts** ### How much does a content delivery network cost for 100 TB a month? Published CDN prices for 100 TB a month range from about $415 to $6,965, on price lists checked August 2026. BlazingCDN lists $415 as of September 2026, bunny.net $500 on its Volume network, CDN77 $990 and Amazon CloudFront $6,965 on pay-as-you-go transfer alone. Regional traffic mix and request fees can move the real total well above the headline figure. ### Is flat-rate or per-GB CDN pricing cheaper for small sites? Flat-rate CDN pricing is usually cheaper below about 46 TB a month. Cloudflare Pro costs $25 a month and Amazon CloudFront Business costs $200 for up to 50 TB, as checked August 2026. Read the fair-use terms first, because some flat plans restrict large file or video delivery, throttle heavy users or push accounts to a higher plan. ### When does a CDN volume commit pay off? A CDN commit pays off when actual usage exceeds the committed volume times the commit rate divided by the pay-as-you-go rate. At a 30 percent discount, you must use at least 70 percent of the commit. Size it to your lowest recent month, not the average, and negotiate how overage and unused volume are handled at renewal. ### Do CDN providers charge request fees on top of bandwidth? Some CDN providers charge request fees and others do not. Hyperscaler pay-as-you-go plans typically bill per 10,000 requests on top of per-GB transfer, which matters for small objects. A workload of 50 KB images makes 20,000 requests per GB delivered, so request fees can rival bandwidth cost, while large installers or video segments barely register. ### How do progressive and blended CDN pricing tiers differ? Progressive CDN pricing tiers charge each rate only on the traffic inside its band, so totals rise smoothly with volume. Blended tiers charge the entire month at the rate of the highest band reached, which creates cliffs where slightly more traffic can cost less. Always model the month just below each tier boundary before accepting a blended quote. ## **Price your own traffic across CDN pricing models** This week, export 90 days of CDN or origin logs. Pull four numbers: monthly TB at the minimum and the peak, the geographic split, the request count and the object-size distribution. Run those numbers through each model in the checklist above, including origin egress at your current hit ratio. That gives you effective cost per delivered GB for flat, metered, tiered and commit options, which is the figure to bring to procurement and to every renewal call. If the math points at high-volume static delivery, the [**BlazingCDN CDN cost calculator**](https://blazingcdn.com/cdn-cost-calculator/) prices the same monthly volume on progressive tiers from $5 per TB, with one global rate and no request fees.
