Enter any domain to get two value estimates side by side: a real-market AI valuation (HumbleWorth, trained on 3M+ historical domain sales) plus a transparent algorithmic breakdown showing exactly how length, TLD, brandability, and keyword premium drive the price. No signup required. Additional insights available in settings.
Every domain has the same skeleton: a name and a TLD. The value of that combination comes from a small number of measurable factors that the market consistently rewards or punishes.
This calculator runs six factor checks and multiplies them against a baseline value. Each factor either boosts the estimate (multiplier > 1) or reduces it (multiplier < 1). The result is a value range — a low and high estimate — because no domain has a single fixed price; it's worth what someone will pay for it.
The brutal truth: domain value is set by a buyer with budget, not by an algorithm. A perfectly average 8-character .com might sell for $50,000 if a fintech startup decides it's their brand. A premium-looking name might sit on a marketplace for five years and never move.
Use this calculator as a sanity check. It will reliably tell you whether a domain is roughly "hand-reg territory," a credible brand candidate, or a premium asset. It cannot predict a specific bid.
For real-world comparables, browse NameBio (~2M historical sales) and DNJournal (weekly top sales). Cross-referencing your estimate against recent comparable sales is the closest you can get to a real number.
The calculator gives an algorithmic estimate, not a guaranteed sale price. It produces a value range based on length, TLD, brandability, keyword premium, dictionary word matches, and penalty factors (hyphens, digits, repeats). Real-world sale prices vary wildly because the actual value depends on a specific buyer who wants that exact name — which no algorithm can predict. Use the estimate as a sanity check, not a quote.
The biggest factors are length (short names are worth dramatically more — a 4-char .com is worth far more than a 10-char one), TLD (.com is worth ~2-10× any other extension), brandability (short, pronounceable, memorable names), and whether the name contains commercially valuable keywords (bank, AI, shop, crypto, etc). Penalty factors like hyphens and digits significantly reduce value.
.com is the universal default. About 53% of all domains registered worldwide are .com, and the vast majority of high-value domain sales (six and seven figures) happen on .com. Other TLDs like .io, .ai, and .app have value in tech and AI niches but still trade for a fraction of .com prices on average.
Both. The Market Value section uses HumbleWorth's AI model — a machine-learning system trained on over 3 million historical domain sales — to estimate auction, marketplace, and brokerage prices. The Brand Value Estimate section uses a transparent deterministic algorithm: length, TLD, brandability, keyword premium, dictionary words, and penalty factors. You can see every component of the algorithmic side in the breakdown below the result.
Listing your domain at a premium marketplace is the most reliable path: Sedo and Afternic are the two biggest brokers and handle high-value sales. For lower-value domains, Dan.com (acquired by GoDaddy) is fast. You can also list directly on marketplaces like Atom (formerly Squadhelp). Premium asking prices typically take months to find a buyer — algorithmic estimates are starting points, not closing prices.
No. The calculator only scores brand strength and market-comparable factors. It does not check trademarks, social handle availability, or any legal claims. Before buying or selling a domain for serious money, run a federal trademark search (USPTO TESS for US) and consider consulting a trademark attorney — generic brandable names can still infringe on existing marks.
Looking to buy instead of sell? If your estimate came back low and you want a stronger name, try the AI company name generator to find brandable, available domains across .com, .io, .app, and more.
