Domain Value Calculator

Calculate what a domain is worth from what comparable domains actually sold for. Type a name, get a deterministic valuation with the working shown - free to start, no card needed.

Calculate a domain's value

The same domain always returns the same price - no randomness, no time-of-day drift.

How the calculation works

Instead of a black-box score, every valuation is built from published parts:

• Eight scored factors - length, TLD strength, brandability, keyword demand, pronounceability, memorability, search footprint, and legal clarity, each scored 0-100 against published rules.
• Comparable recorded sales - the calculation is calibrated against a curated corpus of real closing prices, and the report shows the closest sales it used.
• A value range - every result is a low/fair/high interval, because a single point number overstates certainty.

Check the method before you trust the number

1. The valuation factors and methodology - every factor the model counts, with the parameter sheet published.
2. Measured accuracy - the model is back-tested against held-out real sales; median error and hit rates are public, not asserted.

What the calculator uses as inputs

Only the name itself. It does not ask for traffic, revenue or a self-reported asking price, because none of those are visible to a buyer judging the name cold. From the name alone it scores the eight factors and matches the closest comparable recorded sales; the report shows both, so the calculation can be checked line by line.

Why is the result a range instead of one number?

Because a single point number overstates certainty. Every result is a low, fair and high interval with a confidence reading, and the report says which comparable sales the range rests on. Two names with the same fair value can have very different ranges: one backed by many close sales, the other by few.

Is the calculation deterministic?

Yes. The same domain always returns the same figures at a given methodology revision - there is no randomness and no time-of-day drift - so a value can be reproduced and checked later, and a certificate issued on it can be verified by anyone.

How wrong is the calculator, on average?

The measured error distribution against held-out recorded sales - median error, hit rates within a factor of two and three, and bias - is published on the accuracy page and updated with each methodology revision. The site does not compress it into one accuracy percentage.

Calculate with the evidence in view

• A worked example - a real appraisal and certificate, no account needed.
• Published appraisals - every domain appraisal page, each with factor scores and comparables.
• Domain name patterns - value bands and worked examples per name class.
• Recorded sale analyses - landmark sales read against the model.
• Bulk appraisal - paste a list and get a price for each.
