Portfolio value
estimator.
Estimate your whole portfolio in one go, not one domain at a time. Transparent scoring, instant results, runs entirely in your browser.
Indicative heuristic estimate, not a market appraisal.
One per line, or comma separated. Everything is estimated in your browser; nothing is sent anywhere.
What moves the estimate
Shorter names score far higher. Three and four character names are rare and valuable.
.com leads by a wide margin, then .io, .ai, .co, and other strong TLDs.
Hyphens and numbers reduce value. Clean, pronounceable names score better.
In-demand terms (ai, app, pay, shop, cloud) add a premium.
For a second opinion on individual high-value names, cross-check against real sales comps and read our guide on when to drop a domain.

OpenFrequently asked questions
How is the portfolio value estimated?
The estimator scores each domain on the signals that most affect value: length (shorter is better), extension (.com leads, then .io, .ai, and so on), structure (hyphens and numbers reduce value), pronounceability, and a set of in-demand keywords. It sums the per-domain estimates into a portfolio total. It is a transparent heuristic, not a market appraisal.
Is this an accurate appraisal of what my domains will sell for?
No, and no free tool can promise that. Actual sale price depends on buyers, comparable sales, and demand that no algorithm sees. Use this to spot which names in your portfolio are relatively strong or weak, then cross-check the valuable ones against real sales data like NameBio before acting.
Why estimate the whole portfolio at once?
Most appraisal tools value one domain at a time. Investors and founders think at the portfolio level: what is the whole thing worth, and which names carry it. This tool is built for that bulk, portfolio-first view.
Is my list sent anywhere?
No. The estimate runs entirely in your browser. Your domain list never leaves your device for this tool.
How can I keep my best domains organised?
Import your portfolio into Lemon Domains, tag your strongest names, and track renewals across every registrar so you never let a valuable domain lapse by accident.
