# TLDMath

> Live domain price comparison by the real two-year cost (registration plus the first renewal), across Porkbun, Namecheap, Dynadot, Cloudflare, Vercel, NameSilo, Name.com and Hostinger. Plus a launch kit (DNS records and live checks for your site and email), email hosting comparisons and renewal reminders. Free, no sign-in. TLDMath compares only and does not sell domains.

Prices are per year in USD, live from registrar APIs, refreshed daily for the TLD tables. A renewal more than 1.5x the registration price is flagged as a promo.
