.one domain — straight answers
How much does a .one domain cost?
The lowest first-year price is $2.57 at Porkbun, then $20.08 to renew/yr. Over 3 years the cheapest total cost of ownership is $42.73. The median renewal across the 6 registrars we compare is $20.28/yr, so picking the cheapest scores 62/100 on value.
Where is the cheapest place to renew a .one domain?
Cloudflare has the lowest ongoing renewal at $18.07/yr. Renewal — not the first-year promo — is what you pay every year, so it's the number that matters most for a domain you keep. Across all 6 registrars the annual renewal ranges from $18.07 to $22.49.
Is the first-year price a trap?
Sometimes. The cheapest first year ($2.57) is below its own renewal ($20.08), and some registrars dangle an even lower promo that renews far higher. We rank by 3-year total cost, not the headline first-year price, so the promo can't hide a steep renewal. Always check the renewal before you buy.
