Cloudflare CDN Pricing 2026: Cost-per-GB Breakdown & Decision Matrix

A Pro-plan site pushing 10 TB/month through Cloudflare pays an effective $0.002 per GB for cached delivery. That same site, once it adds Argo Smart Routing, Workers at moderate request volume, and Logpush to an R2 bucket, can land above $0.01 per GB — a 5× increase that never appears on the pricing page. Understanding Cloudflare CDN pricing in 2026 requires you to model the full request path, not just the plan tier. This article gives you the current plan rates, a catalog of every metered add-on that inflates your real cost, an effective-cost formula you can run against your own invoices, and a workload-profile decision matrix that maps your traffic shape to the cheapest CDN option available as of Q2 2026.

Cloudflare CDN Pricing: 2026 Plan Tiers

Cloudflare still ships four tiers as of April 2026. The flat-rate plans bundle proxied HTTP(S) delivery with no published bandwidth cap, which is the core value proposition. The plans themselves have not changed price since their last adjustment, but the ecosystem of metered products around them has grown considerably.

Plan<br>Monthly Cost<br>Bandwidth Cap<br>Key Inclusions

Free<br>$0<br>No published cap<br>Shared TLS, basic caching, limited page rules

Pro<br>$20<br>No published cap<br>WAF managed rulesets, image optimization (Polish), mobile redirect

Business<br>$200<br>No published cap<br>Custom TLS certificates, advanced WAF, SLA guarantee

Enterprise<br>Custom (typically $5,000+/mo)<br>Negotiated<br>Named solutions engineer, 100% SLA, network priority, custom cache configs

Enterprise pricing in 2026 starts around $5,000/month for most organizations, though contracts with committed bandwidth or bundled Zero Trust seats can push initial terms higher. Cloudflare does not publish enterprise rates, and discounts are volume-negotiated.

Does Cloudflare Charge per GB for CDN Delivery?

For standard proxied website traffic — HTML, CSS, JS, images served from cache — Cloudflare does not meter bandwidth on any plan, including Free. There is no published per-GB egress fee for cache-hit delivery, and no origin-pull transfer charge in the way that AWS CloudFront or Google Cloud CDN bill. This is the single largest reason Cloudflare dominates small-to-mid sites: the marginal cost of an additional cached byte is zero at the plan level.

But that framing only holds when your workload stays within pure caching. The moment you step outside of it, metered billing activates, and the "free bandwidth" story changes materially.

Cloudflare's Hidden Metered Costs in 2026

Here is the complete list of Cloudflare products that introduce usage-based charges on top of your plan fee, with approximate Q2 2026 rates:

Argo Smart Routing: $0.10 per GB of transfer through Argo-optimized paths. On a 10 TB/month site this adds $1,000/month to your bill.

Workers (Paid plan): $5/month base, then $0.30 per million requests beyond the first 10 million. CPU-intensive Workers on the Unbound model also bill per ms of compute.

Workers KV: $0.50 per million reads, $5.00 per million writes, $0.50/GB stored per month.

R2 Storage: $0.015/GB stored per month, $0.36 per million Class A operations, $0.36 per million Class B operations. No egress fee — but operational costs add up on write-heavy pipelines.

Images: $1.00 per 100,000 unique transformations delivered; storage at $5.00 per 100,000 original images stored per month.

Stream: $1.00 per 1,000 minutes of video stored, $0.01 per minute of video delivered.

Logpush / Logs: Enterprise-only; typically bundled into the enterprise contract but priced per million log lines in some configurations.

Cloudflare Spectrum (non-HTTP TCP/UDP proxying): Billed per GB of data transferred, with rates varying by plan tier.

The pattern is clear: Cloudflare's pricing model is a flat-rate core surrounded by metered peripherals. Every peripheral you enable widens the gap between your plan price and your actual invoice.

How to Calculate Your Real Cloudflare CDN Cost per GB

The only reliable metric is the effective cost per GB, computed monthly from your actual invoice:

Effective $/GB = (plan fee + all metered add-on charges) ÷ total GB delivered from Cloudflare edge

Pull total delivered bytes from the Cloudflare Analytics API (zone-level, sum of cached + uncached). Pull your invoice total from the billing dashboard. Divide. Here are three real-world profiles as of 2026:

Workload Profile<br>Monthly Spend<br>Delivered TB<br>Effective $/GB

Docs/marketing site, Pro plan, no add-ons<br>$20<br>8 TB<br>$0.0025

SaaS app, Business plan + Argo + Workers<br>$850<br>15 TB<br>$0.055

Media platform, Enterprise + Stream + Logpush<br>$12,000<br>200 TB<br>$0.058

The cache-only site gets extraordinary value. The moment Argo and compute enter, effective cost per GB rises by an order of magnitude. Track this number monthly. It...
