What makes a domain name valuable?
Scarcity, mostly. One real word, very short names and four-digit numbers carry the price. A hyphen costs you. The one factor no tool can see is the buyer.
Scarcity makes a domain valuable. One real word beats two words by more than three to one, and four-digit numbers beat nearly everything with more than four characters. What doesn't move the price much: a made-up word instead of a real one, or a hyphen (it hurts a little). The biggest factor is something no model can see: who wants it.
We've spent a lot of time asking what a domain's value is made of. The honest answer is shorter than most guides make it. Here are the factors in the order they matter, with the numbers from 43,301 reported .com sales since January 2025. Everything is a median of sales of $1,000 or more.
1. Being one real word
This is the biggest lever we can measure. A name that is a single dictionary word sold for a median of $7,877. Two words smashed together: $2,304. Three or more: $1,825. And 44% of the one-word sales were $10,000 or more, against 6.5% of the two-word ones.
Why? There are only so many words, and a company can only have one of them. That's scarcity doing its job. The catch is volume: 471 single-word sales against 17,636 two-word ones. If you own a one-word .com, you hold something rare. If you own a two-word one, which most people do, you hold something ordinary.
2. Being very short
Three-letter .coms: a median of $39,600. Four letters: $3,000. Eight: $2,379. The curve is steepest at the short end, and flat after about eight characters. The full numbers are in domain name prices by length.
3. Being a number people collect
Four-digit numeric .coms are their own market: a median of $11,200 across 206 sales, with 92% at $5,000 or more. At five digits it's $2,144 and at six, $2,000. Mixed letters and digits ("a1b2c3") are a different story: a median of $2,238, which is ordinary.
4. Being a real word vs a made-up one
You'd expect real words to win comfortably. They win, but not by much, once you compare names of the same length:
| Length | Dictionary words | Made-up names |
|---|---|---|
| 5 letters or fewer | $3,188 (1,605) | $2,600 (1,087) |
| 6 to 8 letters | $2,500 (6,729) | $2,146 (877) |
| 9 to 12 letters | $2,081 (11,459) | $1,961 (899) |
| 13 or more | $1,828 (16,061) | $1,678 (886) |
Median price, with sales in brackets. Real-word names are worth a bit more at every length, between 6% and 23% on the medians, and more in the top tail for short names. Overall the two groups have the same median ($2,025) because made-up names tend to be shorter, which pushes the other way. So "it's a real word" is a modest edge. "It's a rare real word" is the big one.
5. Having a hyphen (it hurts)
Hyphenated .coms sold for a median of $1,725 (1,454 sales), and only 1.9% reached $10,000. That's below even the three-or-more-word group. Nobody says a hyphen name out loud without wincing. If you own one, price it as a lesser name.
What none of this sees: the buyer
Every number above describes names in bulk. It says nothing about one name, because a single sale is decided by one person's reason to buy. In our own testing of an AI appraiser, the biggest misses were names that sold for $24,000 to $40,000 when the AI had said $1,350 to $4,000: a local diner, a lab, and a few numeric names (the full test). Nothing in the letters said so. A buyer with a business and a budget did.
That's the gap we're trying to measure with human appraisals. People can know things a model can't: that the diner is a real regional chain, or that a word is suddenly everywhere in one industry. We think people will beat the robots there. We haven't measured it yet, and we'll publish the result either way.
A checklist you can actually use
- One real word? You're in the rare group. Get a broker's opinion, not a calculator's.
- Four letters or fewer? Same.
- Four digits? You're in a collectors' market. Look at what four-digit numbers sold for recently.
- Two words, ordinary, eight to twelve letters? You're in the middle. The typical price band is the one in how much is my domain worth, and you should price off real comparable sales.
- Hyphen or odd spelling? Lower the guess.
The data, for the record. Reported .com sales since January 1, 2025 (43,301), merged from multiple sources, de-duplicated, wholesale auctions excluded, at least $1,000. "Dictionary words" means every part of the name is an English word in a standard word list.
