Everything your servers, storage and CDN send to users and other services on the internet.

Each provider's own CDN: CloudFront, Cloud CDN, Front Door, Cloudflare or Spaces CDN.

Traffic inside the cloud

GB / month

Replication, backups and calls to services in a different region.

GB / month

Service-to-service calls, load balancing and database replicas in other zones of the same region.

NAT and servers

GB / month

Outbound calls, package and image pulls from private subnets.

Usually one per availability zone.

Sets pooled transfer allowances and Cloud NAT's per-VM fee.

Monthly data transfer on Cloudflare$0.00This traffic fits in the included allowances

Cloudflare runs no servers, so region, zone and NAT traffic is priced on whatever compute sits behind it.

How is cloud data transfer billed?

As of September 28, 2026, on Cloudflare internet egress is free; Cloudflare CDN starts at $0 per GB; and there is no managed NAT gateway to pay for. Your bill is each traffic type's gigabytes times its rate, tier by tier, plus any hourly charges.

monthly = tiered(internet egress) + CDN delivery + misses × origin fetch + inter-region GB × rate + cross-AZ GB × rate + NAT gateways × hourly × 730 + NAT GB × processing rate

This page uses the same method as the Cloud Egress Cost Calculator, which explains each term and assumption in full.

Worked example

A workload in North America on Cloudflare: 10 TB a month to the internet, 500 GB to another region, 1,000 GB across zones, 500 GB through NAT, on 3 servers.

  1. 1Every line falls inside the free allowances.

$0.00 a month on Cloudflare, $0.00 a year. The cheapest cloud listed that runs servers, DigitalOcean, would cost $0.00 a month.

Frequently asked questions

What does Cloudflare charge for bandwidth?

At list prices, internet egress is free; Cloudflare CDN starts at $0 per GB; and there is no managed NAT gateway to pay for. Cloudflare charges nothing for bandwidth on its CDN or for egress from R2 storage; R2 bills storage ($0.015 per GB-month) and operations instead. It does not rent virtual machines, so there is no NAT, zone or region traffic to price: those lines apply to whatever compute sits behind it.

Is Cloudflare bandwidth really free?

For the CDN and for R2 storage, yes: Cloudflare charges no per-GB fee for data delivered to the internet on any plan, and R2 has no egress fee. R2 bills storage at $0.015 per GB-month and operations at $4.50 per million writes and $0.36 per million reads. Cloudflare does not rent servers, so your compute and its internal traffic still sit with another provider.
