An at-cost registrar sells domains at exactly what the registry charges them — no markup, no promotional-to-list-price jump.
How domain pricing works normally
The chain: Registry → Registrar → You.
Verisign is the registry for .com. They charge registrars $10.26/yr per .com domain (2026 wholesale rate). ICANN adds a mandatory $0.18 fee. Total cost to the registrar: $10.44/yr per .com.
A conventional registrar then adds margin. Namecheap charges $13.98/yr (margin: $3.54). GoDaddy charges $21.99/yr (margin: $11.55). The margin funds the business: marketing, support, infrastructure, profit.
The at-cost model
Cloudflare charges $10.44/yr — exactly what the domain costs them. No margin. Zero. The business logic: Cloudflare makes money from Workers, Pages, Zero Trust, and other platform services. Registration is a loss-leader that keeps domains on Cloudflare DNS. The registrar product is profitable only indirectly.
This model is structurally sustainable for Cloudflare but impossible for a pure-play registrar. If Namecheap removed its margin, it would need to cut its entire support, marketing, and infrastructure budget.
What at-cost means for you
First-year vs renewal: no surprise. An at-cost registrar charges the same rate every year. There’s no promotional-to-list-price jump. $10.44 in year one is $10.44 in year five.
Long-term TCO advantage: the savings compound. Over 10 years at 10 domains, Cloudflare at-cost saves you $354 vs Namecheap ($10.44 vs $13.98, 10 domains, 10 years: $354 difference).
No affiliate commission: Cloudflare doesn’t pay affiliate commission. This is why at-cost registrars are underrepresented on comparison sites. Every site that ranks registrars by commission payout will structurally underweight Cloudflare. Including, sometimes, us — except we flag our commission status on every row.
Is Porkbun at-cost?
Porkbun’s .com renewal ($9.73) is actually below Cloudflare’s at-cost price ($10.44). This is unusual. Porkbun subsidises .com pricing from margin on other TLDs and services. They’re not technically “at-cost” in the Cloudflare sense — they’re “below-cost on .com, cross-subsidised.”
Why it matters when picking a registrar
At-cost pricing is the strongest structural guarantee that your renewal price won’t surprise you. No promotional pricing, no year-2 jump, no anniversary email hiding a 22Ã- increase. If long-term price predictability is a priority — especially for domains you plan to keep for 5+ years — at-cost registrars are the correct category to evaluate first.
