Methodology
How the numbers are made. Every one of them.
Each price is a registrar’s own listed price, read from its API, with the time it was read. Nothing is estimated, converted or projected.

Capture
Once a day
Every registrar’s list is read at 10:23 UTC. Every day is kept, so each change has a date.
Failed reads
The last good price stays, with its own time. Older than 36 hours is marked on the page.
Searched names
Priced live at every registrar for that exact name, premium included, except where marked “Std. rate”.
Definitions
- First year
- What you pay at checkout for the shortest term. Longer minimums (.ai: 2 years) are paid upfront, shown per year and in total.
- Renewal
- The registrar’s standard yearly renewal price today.
- Transfer
- Moving a domain you own to that registrar. Usually adds a year; .uk moves free and adds none.
- Restore fee
- Getting a domain back after it expires and the grace period ends, as the price list shows it.
- True cost
- First term plus yearly renewals at today’s standard prices, at one registrar, over 1, 2 or 5 years.
- Cheapest · typical · highest
- The lowest, median and highest total across registrars. A spread, not a “±”: every input is an exact price.
- Announced changes
- Shown next to the true cost as “if passed on in full”. Never added in; nothing unannounced is projected.
- Promo
- A renewal more than 1.5 times the first-year price.
- Price change
- A standard price that moves by at least $0.50 or 5% from one day to the next.
What we don’t do
No estimates
No coupon codes, and a price a registrar doesn’t list is left blank.
No conversion
USD only. A registrar that prices only in another currency isn’t included.
No paid placement
Some buy links are affiliate links. They never change the order.
The data
Changelog
Every change to what a number means or where it comes from.
| Date | Change |
|---|---|
| Oct 5, 2026 | TLDMath Renewal Index published: 20 extensions, equal weight, median standard renewal, chain-linked daily, Sep 26, 2026 = 100. Full daily price history downloadable as CSV. |
| Oct 5, 2026 | True cost over 1, 2 and 5 years on every extension page, with the spread across registrars (cheapest, typical, highest). Announced registry changes are shown apart, never added to the number. |
| Oct 5, 2026 | Every price on the extension and registrar pages shows when it was read. A price older than 36 hours (the registrar’s last refresh failed, so its last good price was kept) is marked. |
| Oct 5, 2026 | Hostinger added: 8 registrars. Its API gives standard prices only, so its prices for a searched name are labelled “Std. rate”. |
| Oct 5, 2026 | .si added: 93 extensions. Namecheap is now read at 40 extensions a minute to stay under its API limit, so every extension gets a Namecheap price each day. |
| Oct 4, 2026 | Restore (redemption) fees added where a registrar’s price list includes them: Namecheap, Dynadot and Name.com. |
| Oct 4, 2026 | 54 more extensions (92 in all), and the cheapest transfer price on the price index. |
| Oct 3, 2026 | Price history and change log per extension; a change is listed when a standard price moves by at least $0.50 or 5%. |
| Sep 23, 2026 | Daily capture of every registrar’s standard price list begins. Every day is kept. |
