How to Value a Domain Name

You've spotted a name you like. Maybe it's in an expired auction that ends Friday, or maybe it's already in your account and someone just sent an offer. You need a number, and the free appraisal tool just gave you one that feels a little too good.

This guide shows you how to turn that number into a decision: what to bid, what to ask, and which extension is worth paying for. It's the hands-on chapter of our domain investing guide, and the whole check takes about 15 minutes per name.

 

What a domain name appraisal tells you

A domain name appraisal is an estimate of what a name could sell for, based on its traits and on past sales of similar names. In practice, you're juggling three different numbers, and mixing them up is how beginners overpay.

• Tool estimate: the instant figure an algorithm gives you. It's quick and free, and it's a signal to look closer.
• Wholesale value: what another investor would pay.
• Retail value: what the business, organization, or person who will actually use the name pays for it.

Wholesale always sits well below retail. Visual 1 shows how the three numbers stack up, and why the tool estimate floats. It can land above, between, or below the other two.

 

Five checks that move value

Before you research anything, run a quick yes/no screen. If a name fails two or more of these, it probably isn't worth your 15 minutes.

• The say-it-once test: Say the name out loud to a friend. Can they type it without asking how it's spelled? Hyphens tend to fail here, and in Dynadot's Q2 2026 Domain Intelligence Report, not one sale above $5,000 on our marketplace had a hyphen.
• Extension and buyer pool: Who would buy this exact extension? A great word in the wrong extension has fewer buyers. More on that in the TLD section below.
• Commercial intent: Could a business make money under this name? A quick demand check helps: count how many other extensions the same string is already registered in. That cross-TLD count was the report's strongest signal at the top of the market.
• Brandability: Does it sound like a company you'd trust? Short helps a lot. Close to 58% of the report's $5,000+ sales were five characters or shorter.
• History and trademark: Look up the name's past on the Wayback Machine and its registration record with a WHOIS lookup, then search the USPTO's Trademark Search for live marks. A name built on someone else's brand invites a legal dispute, and serious buyers walk away from it.

 

Evaluate a name in 15 minutes

Here's the routine, start to finish. Visual 2 shows the four steps, plus the detour you take when there are no close sales to compare with.

1. Get a baseline (2 minutes): Run the name through Dynadot's free domain appraisal tool. It weighs memorability, length, keyword popularity, TLD value, historical aftermarket sales, search trends, and character combinations, and it keeps improving from user feedback. If the name might be unregistered, check domain search first. You may be able to simply register it. Write the number down and move on.
2. Find 3 to 5 sold comps (8 minutes): Search NameBio for sold names that share your name's length, extension, and keyword category. Use sold prices only, never asking prices, since an asking price is just what a seller hopes for. Then note where each sale happened. NameBio's trends reports count sales at venues like Dynadot, GoDaddy, Namecheap, DropCatch, and NameJet as wholesale, and sales at Afternic, Sedo, Dan, and brokers at $1,000 or more as retail. That split gives you both ends of your range.
3. Check history (3 minutes): Run the history and trademark check from the screen above if you haven't yet. Spam history or a trademark conflict ends the evaluation right here.
4. Write a low/high range (2 minutes): The low end comes from your wholesale comps. The high end comes from your retail comps. One line in your notes is enough: "Wholesale low to high, retail ceiling if an end user appears."

 

When NameBio shows no close sales

This happens a lot with brandable names. When it does, widen the search.

• Break the name apart: Search each word on its own and look at how names using that word sold.
• Check other extensions: See whether the same word sold in a different TLD. Treat it as a loose guide, since extensions don't price alike.
• Count cross-TLD registrations: If the string is registered in dozens of other extensions, people clearly want it. In the Q2 report, the median $5,000+ sale was registered in 26 other TLDs, against 2 market-wide.
• Ask the community: Investor forums like NamePros run appraisal threads where experienced eyes will tell you what they'd pay.
• Price from the wholesale end: No comps means more risk, so your range should lean low.

 

Before you bid

Set your maximum bid from the wholesale end of your range, then make sure the purchase still makes sense once you add the cost of holding the name. That's the whole rule.

Most beginners buy at expired domain auctions and backorders, which are wholesale venues by definition. Dynadot's expired auctions run for 7 days, add 5 minutes whenever someone bids in the final 5 minutes, and support proxy bids. The listings also show handy filters such as Dynappraisal, backlinks, age, and a dotDB TLD count (that cross-TLD signal again). Use them to build a shortlist, then run your 15-minute check on the names that make the cut.

• Set your ceiling before the bidding heats up: Write it down from your wholesale comps and stick to it.
• Count the hold: In most cases an expired win includes a one-year registration term, but every year after that costs a renewal. Most names won't sell to an end user for years, if ever, so budget for the wait.
• Use a proxy bid: Enter your maximum once and walk away. Those 5-minute extensions are exactly where auction fever kicks in.
• Backorders follow the same rule: Placing one is free, and you only pay if we catch the domain. If several people backorder it, it goes to a backorder auction, and your ceiling doesn't change.

Good names really do turn up this way. Expired auctions produced four of the ten largest sales on Dynadot's marketplace in Q2 2026, including betzz.com at $15,210.88 and 2290.com at $12,909.88. Both are short and hyphen-free, and competitive bidding set their prices.

 

Before you sell

Set a floor from your wholesale comps and an asking price from the retail end of your range. The floor is what you'd happily accept from another investor today. The ask is what the right end user might pay after a real sales effort.

Then figure out who's actually in front of you. Quote an investor your retail price and you'll likely hear nothing back. Quote a business your wholesale price and you've left money on the table. When you list a name, a Buy-It-Now price at the retail end is a sensible default: in the Q2 report, Buy-It-Now handled 60% of sales above $5,000.

Listing tactics, pricing formats, and transfers are covered in our step-by-step guide to selling a domain.

 

Choosing a TLD: same name, different buyers

Judge an extension by who would buy it. The same word can be a great buy in one TLD and a slow seller in another, simply because each extension has its own buyer pool. Visual 3 compares three common choices.

• .com: It has the broadest buyer pool, made up of businesses everywhere plus other investors, so it's the fastest to resell at both wholesale and retail. It also carried 70.6% of orders on our marketplace in Q2 2026.
• Country code (ccTLD): Buyers are mostly businesses in that country or language, plus a few sectors that adopted an extension as their own, like tech startups with .io. Demand is steady inside that market. .io had the strongest median in the Q2 report, more than three times the market median.
• Niche extension: Buyers are businesses in that industry or community. The pool is narrower but focused, so resale is slower and you'll wait for the right buyer. Comps are scarce too, so stay near the low end when you bid.

Whatever the extension, compare it only with sales in that same extension. Pricing a .co from .com comps is how ranges go wrong. For a fuller picture, see how domain extensions differ.

 

Beginner mistakes, and what tools can't see

Appraisal tools miss the "cognitive value" a person spots instantly: wordplay, cultural meaning, or a fit with a trend that's just starting. That cuts both ways, so a tool can underprice a clever brandable and overprice a clunky keyword string. Your judgment fills that gap. Here are the mistakes we see most often.

• Treating the tool number as a price: It's a starting signal. Comps set the price.
• Comparing with asking prices: Only completed sales count.
• Bidding at retail: You'd need an end user to pay your exact ceiling just to break even.
• Ignoring renewal costs: A cheap win that sits for years gets expensive.
• Falling for your own taste: Ask who the buyer is. If you can't name one, that's your answer.
• Rushing: Fifteen minutes of checking is cheaper than one bad bid.

The verdict

A domain name appraisal is worth doing every time you're about to spend or accept money, and it works best as a three-number habit: check the tool, find the comps, then decide where you stand between wholesale and retail. Buy at wholesale, sell toward retail, and let your comps settle any arguments.

Domain name appraisal FAQ

 

Does domain age make a name more valuable?

Not by itself. In Dynadot's Q2 2026 data, names from 1 to 20 years old sold at the market median with no upward trend. Names older than 21 years carried a modest premium, so age raises the odds of a standout sale more than it raises the typical price.

 

Are hyphens or numbers bad for value?

Hyphens usually hurt. Hyphenated names averaged about 0.7x the market price in the Q2 report, and none sold above $5,000. Pure numeric names are different: they were rare but averaged roughly 2.5x the market price.

 

Is a .com always worth more than other extensions?

Usually, because .com has the largest pool of buyers. It isn't automatic, though. In Q2 2026, .io posted a higher median than .com, and non-.com extensions made up a bigger share of sales above $5,000 than of sales under $50.

 

How much should I bid on an expired domain?

Bid up to the wholesale end of your comp range, minus what you expect to spend on renewals while you hold it. Set that number as a proxy bid before the auction's final minutes, and let the name go if bidding passes it.

 

What is NameBio, and is it free?

NameBio is a searchable database of reported domain sales, and investors use it as the standard source for comps. You can search it for free, and paid tiers add more results per search and sales under $100. It doesn't capture every sale, so treat it as a strong sample of the market.
