.biz domain — straight answers
How much does a .biz domain cost?
The lowest first-year price is $6.69 at Porkbun, then $19.05 to renew/yr. Over 3 years the cheapest total cost of ownership is $44.79. The median renewal across the 5 registrars we compare is $18.98/yr, so picking the cheapest scores 58/100 on value.
Where is the cheapest place to renew a .biz domain?
Cloudflare has the lowest ongoing renewal at $16.18/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 5 registrars the annual renewal ranges from $16.18 to $19.05.
Is the first-year price a trap?
Sometimes. The cheapest first year ($6.69) is below its own renewal ($19.05), 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.
