CDN compared: what 50 TB a month really costs on Cloudflare, Bunny and CDN77

Anyone running a site or service that shifts 50 TB a month knows that the number that really matters isn't the headline price on the homepage, but what you end up paying for the last GB. We compared three public price lists, verified today, 7 October 2026: Cloudflare Business, Bunny.net and CDN77.

Cloudflare Business: fixed fee plus overage

According to Cloudflare's official Business plan page, the plan includes custom and universal SSL certificates, PCI and SOC 2 Type II compliance, up to 10 Cloudflare Rules for customisation, a 100% uptime guarantee (SLA), and support via chat and ticket. The plan is sold per zone (domain), not per account: anyone with multiple sites pays the fee once for each one.

On the traffic side, several industry sources agree on a tiered structure for non-cacheable traffic beyond what's included in the plan: $0.040/GB up to 10 TB, and $0.037/GB from the 10 TB threshold up to 50 TB. This figure appears consistently across multiple independent analyses of Cloudflare's price list, but it isn't stated verbatim on the public plan page as checked today: anyone about to sign a contract should get it confirmed in writing by their account manager before committing, since standard cacheable HTTP traffic remains included in the base fee.

Bunny.net: no base fee, just GB

Bunny.net's official price list, published on the provider's pricing page, has no fixed monthly fee: it's a pay-as-you-go service with a $1 monthly minimum. For the standard network covering Europe and North America, the price is $0.01/GB. At 50 TB (roughly 51,200 GB), the maths is straightforward: $512 a month, all in, with no fixed charge to add on top.

Bunny also publishes a direct comparison on its own site: for 5 TB of traffic across Europe and North America, it lists $50 for bunny.net versus $165 for CDN77, $220 for BytePlus, $125 for CacheFly and over $425 for CloudFront.

CDN77: tiered plan with stated overage

CDN77 sells a "Growth" plan at a fixed price that covers a volume far higher than the tier we're examining here: according to the official price list, the plan costs $990 a month for traffic volumes up to 250 TB, with all platform features included, and any overage is billed at $3.96 per TB. At 50 TB, the Growth plan is heavily underused: you'd still pay the full $990 fee regardless of the volume actually consumed below the threshold.

The comparison at 50 TB

Provider	Cost at 50 TB/month	Note
Cloudflare Business	per-zone fee + tiered overage ($0.040/GB up to 10 TB, $0.037/GB 10-50 TB) on non-cacheable traffic	low fixed fee, variable cost depends on share of non-cacheable traffic
Bunny.net	roughly $512 (50,000 GB x $0.01/GB)	no fixed fee, you only pay for the GB used
CDN77 Growth	$990 flat up to 250 TB	only worthwhile above roughly 25-30 TB if you're filling the tier, otherwise oversized at 50 TB

Honestly, for 50 TB a month of genuinely non-cacheable traffic, Bunny.net comes out as the cheapest of the three once you do the sums, since it has no fixed fee and the per-GB price stays low across the whole Europe/North America tier. Cloudflare Business remains competitive if a large share of traffic is served from cache, since that portion doesn't generate overage. CDN77 only pays off if real volume gets close to the 250 TB included in the Growth plan; otherwise the fixed fee becomes a burden.

For anyone running hosting panels who needs to reconcile these costs with customer billing, a billing system like Koabilling makes it possible to tie the CDN traffic thresholds stated by the provider directly to resale plans, avoiding the nasty surprise of overage showing up on a customer's invoice at month's end.
