A domain is worth what a comparable name recently sold for, adjusted for how it scores against that comparable. This calculator makes that explicit: \(\text{Estimated Value} = \text{Comparable Sale Price} \times \frac{\text{Quality Score}}{50}\), where the quality score is a weighted average of six factors — extension (25%), length (20%), name type (20%), commercial demand (15%), clean characters (10%), and age (10%), each scored 0 to 100. A score of 50 means the domain looks like the comparable and should be worth about the same. A score of 100 means roughly twice it; a score of 25, roughly half. The output is deliberately a range — the point estimate ±40% — because appraisals of the same name from different tools routinely disagree by more than that. How the individual factors score, at a glance: • **Extension** — .com 100, .io/.ai/.co 70, .net/.org 55, anything else 30 • **Length** — (20 − characters) ÷ 17 × 100, so 3 characters or fewer tops out and 20+ characters scores zero • **Name type** — exact-match keyword 100, brandable 80, two-word compound 60, random string 25 • **Clean characters** — 100 for letters only, 20 if the name contains a hyphen or a digit • **Age** — years ÷ 15 × 100, capped at 100 • **Commercial demand** — (monthly searches × CPC × 12) ÷ $60,000 × 100, capped at 100 What this model deliberately does not do is invent a comparable for you. Automated appraisal tools hide that assumption inside a proprietary score; here it is an input you have to justify. ## How to Use This Estimator: A Strong Commercial .com Take a twelve-character exact-match keyword .com with no hyphens or digits, registered twelve years ago, on a term with 40,000 monthly searches at a $6.50 cost-per-click, benchmarked against a comparable name that sold for $25,000. Length = (20 − 12) ÷ 17 × 100 = **47.1**. Extension = **100**. Name type = **100**. Clean characters = **100**. Age = 12 ÷ 15 × 100 = **80.0**. Commercial demand = 40,000 × $6.50 × 12 = $3,120,000 of annual click value, far past the $60,000 saturation point, so **100**. Quality Score = (47.1 × 20% ) + (100 × 25%) + (100 × 20%) + (100 × 10%) + (80 × 10%) + (100 × 15%) = **87.4 / 100**. Valuation Multiple = 87.4 ÷ 50 = **1.75×**. Estimated Value = $25,000 × 1.75 = **$43,706**, with a negotiating range of **$26,224 to $61,188**. Notice which factor is holding the score down. Everything except length is at or near maximum; twelve characters costs this name more than twenty points of quality score. That is the single most useful thing an auditable model tells you and an opaque one does not. ## A Second Example: A Weak Name at the Other End of the Scale Now take a fourteen-character two-word compound on .net, containing both a hyphen and a digit, registered two years ago, on a term with 500 monthly searches at a $1.20 cost-per-click, benchmarked against a $2,500 comparable. Length = (20 − 14) ÷ 17 × 100 = **35.3**. Extension = **55**. Name type = **60**. Clean characters = **20**. Age = 2 ÷ 15 × 100 = **13.3**. Commercial demand = 500 × $1.20 × 12 = $7,200 of annual click value, which is 12% of the $60,000 ceiling, so **12.0**. Quality Score = **37.9 / 100**, a multiple of **0.76×**, giving an estimated value of **$1,897** in a range of **$1,138 to $2,656** — below its own comparable, despite the comparable already being a modest sale. Two inputs do most of that damage: the hyphen-and-digit penalty and the near-zero commercial demand. Drop the hyphen and the digit alone and the score rises by eight points, which is a concrete argument for buying the clean variant instead. ## Why a Range, and Why the Comparable Matters More Than the Score Domain valuation has no observable market price. Unlike a stock or a house on a street of near-identical houses, most names trade once, privately, to a buyer with an idiosyncratic reason for wanting that exact string. Public appraisal tools paper over this by returning a single confident number generated by a model trained on past sales — which is why two of them will happily value the same name at $4,000 and $19,000. The honest response is to be explicit about the anchor. If you enter a $25,000 comparable, every number this calculator returns is denominated in that assumption; enter $8,000 instead and the estimate falls by two-thirds without a single factor score changing. So spend your effort on the comparable: find an actual completed sale of a name with the same extension, similar length, and similar commercial intent, and use that. A named-sale anchor with a mediocre score beats a great score anchored to a guess. The ±40% band is there for the same reason. Treat the low end as roughly where a motivated seller lands and the high end as roughly what an end-user buyer with a specific need might pay, and treat any single point inside it as a starting position rather than a price. ## Limitations This is a ranking model, not a market price. It performs exact arithmetic on the factors and weights shown, but those weights are a documented editorial judgement about what the aftermarket rewards — they are not fitted to a sales database, and no automated model can capture the reason most premium domains actually sell, which is that one specific buyer needed that specific string. It also cannot see several things that decisively move real prices: trademark exposure (a name that infringes a mark is worth less than nothing, since it invites a UDRP transfer), existing traffic and backlink profile, prior use for spam that has left the domain penalised, renewal cost on premium extensions, escrow and transfer fees, and how long you can afford to hold the name before selling. Check a trademark database before buying, and never let a calculator talk you past that step. Finally, the commercial demand factor uses search volume and CPC as a proxy for value. That proxy works for exact-match commercial keywords and breaks down badly for brandable names, where the entire value is in memorability that no keyword tool measures. If you are valuing a brandable, expect this factor to understate it and weight your comparable accordingly. ## Related Calculators A domain is usually the first line of a larger budget, not the whole of it. Once you have a name, the [Website Hosting Cost Calculator](/calculators/website-hosting-cost-calculator) prices the monthly bill for actually running a site on it. If you are buying a domain as part of an existing online business rather than on its own, the [Business Valuation Calculator](/calculators/business-valuation-calculator) values the revenue and profit alongside the name. And if you entered a cost-per-click figure above, the [Breakeven ROAS Calculator](/calculators/breakeven-roas-calculator) is a quick way to sanity-check what traffic at that price would actually have to return. ## Frequently asked questions ### How do I calculate what a domain name is worth? Score the domain on extension, length, name type, commercial demand, clean characters, and age, weight those into a single 0–100 quality score, then multiply a real comparable sale price by score ÷ 50. A score of 50 means the domain is worth roughly what the comparable sold for; 100 means about twice it. ### Why do domain appraisal tools give such different numbers? Because there is no observable market price for a domain. Most names sell once, privately, to a buyer with a specific reason for wanting that exact string, so appraisal models are extrapolating from thin and unrepresentative sales data. Two reputable tools valuing the same name thousands of dollars apart is normal, which is why this calculator returns a range rather than a single figure. ### How much does a hyphen or a number reduce a domain's value? A lot. This model scores a name containing either at 20 out of 100 on the clean-characters factor against 100 for letters only, costing eight points of overall quality score. The real-world penalty is often larger, because hyphenated and numeric names are harder to say aloud, easier to mistype, and routinely lose type-in traffic to the clean variant. ### Is a .com really worth that much more than a .io or .net? In resale terms, generally yes — which is why extension carries the heaviest weight here at 25%. This reflects observed aftermarket pricing rather than any technical difference: .com is what buyers default to typing and what acquirers ask for. A .io or .ai can still be the right choice for a product launch; it is simply a weaker asset to resell. ### What should I use as the comparable sale price? An actual completed sale of a name with the same extension, similar character length, and similar commercial intent, taken from a public domain sales database. This is the single most important input — every result is denominated in it. A well-chosen comparable with a rough score beats a precise score anchored to a guess. ### Does domain age really affect value? It is a modest factor, weighted at 10% here and capped at fifteen years. Age correlates with an established backlink profile and a clean history, both of which buyers pay for, but a twenty-year-old name on a weak term is still a weak name. Treat age as a tiebreaker between similar candidates rather than a value driver on its own. ### Does this calculator check for trademark problems? No, and no valuation tool can. A domain that infringes an existing trademark is worth less than nothing — it invites a UDRP complaint that can transfer the name away from you. Search a trademark database before buying any name, regardless of what a valuation model says it is worth. ### Why does the estimate use a range instead of one number? Because a single number implies a precision the domain aftermarket does not have. The ±40% band is a rough negotiating range: treat the low end as where a motivated seller tends to land and the high end as what an end-user buyer with a specific need might pay, and use the midpoint only as an opening position. ## Related concepts - **Comparable Sale** — A completed public sale of a similar name, used as the dollar anchor for a valuation.
