Estimate a Cloudflare bill from plan fee, Argo smart routing and the origin egress that caching still leaves behind.
Cloudflare's headline model is a flat plan fee with no per-GB delivery charge, so the variable part of the bill comes from optional add-ons like Argo and — crucially — from the origin egress your own cloud still bills on every cache miss. Raising the hit ratio therefore cuts the bill even though the CDN itself does not meter bytes. Comparing a flat-fee CDN with a per-GB one only works if you count origin egress on both sides, which is where most CDN comparisons go wrong. Plan pricing, Argo rates and enterprise commits all change, so confirm current pricing with Cloudflare and your origin provider.
Cloudflare CDN Cost
cost = plan fee + add-ons + (Argo price × delivered GB if enabled) + (1 − cache hit ratio) × delivered GB × origin egress price.
