Live prices from Porkbun · Dynadot · Cloudflare · Namecheap · Vercel
The real price of a domain is year two.
Registrars advertise the first year and bury the renewal. TLDMath checks every registrar live and adds the renewal, so you see what a domain actually costs before you buy.

How the math works
Ask every registrar, live
Each search queries registrar APIs directly for that exact name, including premium pricing. No stale price lists.
Add the renewal
We rank by what you pay over two years, plus any minimum term like .ai’s two years. A $1 promo that renews at $26 loses.
Buy wherever wins
We don’t sell domains. You buy directly at the registrar. Affiliate links never change the order.
Ask your AI. It’ll do the math.
