What is a domain appraisal?

A domain appraisal is an estimate of what a domain name would sell for. Ours is instant, free, and transparent: a value in USD, the three prices a name can fetch, a 0–100 name score, and every factor that moved the number, shown as it is here.

How much is my domain worth? Nine names, nine answers

Domains are worth wildly different amounts for reasons that are easy to explain once you see them. These nine span the range, from a one-word .com to the biggest sale on record, and the numbers are the model’s own. Click one to see its appraisal.

How the domain value estimator works

  1. Type a domain

    Any name on any extension: one you own, one you’re eyeing, or one you’re about to register. The appraisal appears as you type.

  2. Read the breakdown

    A value in USD with a quick-sale, marketplace, and brokerage range, a 0–100 name score, and every signal the model read, with strengths and watch-outs.

  3. Check it against the market

    Live availability and price, the domain’s own reported sale if it has one, keyword sale history, extension competition, Domain Rating, and age.

What makes a domain name valuable

The model reads more than a dozen signals about the name, its extension, its history, and the live market before it settles on a number. Here is what it found for voice.ai.

  • LengthShort names earn a steep premium; long ones lose a little per character.
  • Word typeOne dictionary word is the top tier, then a natural coined name, then a two-word compound. Random letters price near zero.
  • Familiarity and brandabilityCommon, concrete nouns (clay, voice) and action verbs (grow, deploy) read as brands. Abstract words don’t.
  • Keyword demandWords with a track record of real domain sales carry a capped premium, from NameBio’s sale statistics.
  • Extension.com is the benchmark. .ai holds a clear premium over .io and .co; extensions with no resale market are capped.
  • PenaltiesDigits, hyphens, a leading stopword, and generic prefixes like get or my (getharbor) all take value away.
  • FloorsA reported sale, a top-10,000 website, or a one- to three-letter .com lifts the estimate above what the letters alone earn.

A range, not a number that only looks precise

An appraisal of $158,328 suggests an accuracy no tool has. A domain has three prices depending on who is buying and how fast, so the result shows all three.

joyride.comOne name, three prices
Auction$5.3KWhat it fetches fast, from another investor: an expired-domain auction or a wholesale flip.
Marketplace$16KThe expected price as a listing on a marketplace, our headline number.
Brokerage$43KA broker’s ask to the one end user who needs this name. The ceiling, not the average.

The three numbers are $5.3K, $16K, and $43K: the same name is worth 8 times more to the right buyer than in a quick sale. A single figure would hide that.

What the model can’t see

The factors are calibrated against reported sales from 2025 and 2026, and where we had to choose, the model errs low: a compound word that sold for six figures was a survivor, and most names built the same way never sell at all. What no name-based model can price is the buyer. A company that has already named itself after your word will pay many times the estimate, a trademark can make the name unusable, and private deals never appear in any dataset.

So the result is honest about its limits. A reported sale, a place in the world’s top 10,000 websites, and a short .com each override the letters-only estimate, the summary says when that happened, and every result carries the month its data was built.

Check domain value against the live market

An estimate is only useful next to a real price. Every appraisal runs a live registry check, so the result says whether the name is available, premium, listed, or taken, and how the price compares.

  • AvailableFree to register at the standard price. When the estimate is well above that, the result says so.
  • PremiumAvailable, but priced by the registry or a reseller. The price shows next to the estimate.
  • For saleListed on the aftermarket. The asking price shows, with a note on whether it sits below, near, or above the estimate.
  • TakenRegistered and not listed. Someone wanted this name, which is a demand signal in itself.
  • Extension competitionHow many of the popular extensions of the same name are already registered. A name taken on twenty extensions is in demand.
  • Domain ratingA 0–100 measure of a domain’s backlink strength, from a live source. It separates an operating website from a parked name.
  • Domain ageThe registration date, straight from the registry. Long-held names signal stability and search-engine trust.

Where the numbers come from

No black box. Four kinds of data go into every appraisal, and the result page shows which ones it used.

  • 38,000+ sales
    Recorded salesRealized prices from public domain sales going back to 1998, from single words to record-setting names. A domain’s own sale shows on its result.
  • 32,000 words
    Word knowledgeWord frequency from a trillion-word web corpus, plus concreteness ratings for 14,545 words and 2,490 verbs: how the model tells clay from durable.
  • Top 10,000 sites
    Established websitesA global ranking of the most-visited domains. A name on the list is priced as a business, not as letters.
  • Per lookup
    Live signalsAvailability and price from our own registry check, plus registration dates and domain ratings from live sources.

The dataset is rebuilt every month. This one was built in September 2026, and every result says so.
