    “extensive data in format that is easy to understand”

    Martin Grovdahl, USAOct 2026

  • Trustpilot · translated ★★★★★
    “I appreciate the good overview and the wealth of metrics when you want to look at a stock more closely. The fair value estimate is sometimes more cautious than elsewhere, which I see as a positive. There is even personal contact: a human replies, not a bot. Very satisfied, and I recommend this portal.”

Frequently Asked Questions

Is it still worth investing in stocks now?

That depends less on the calendar than on the price. We calculate the fair value of 40,000+ stocks every day and show how far the whole market, each sector and each single stock sit from it. An expensive market does not rule out undervalued single stocks, it only changes how much you put in at once. See the market and the cheap sectors →

What is Fair Value Calculator?

Fair Value Calculator estimates what a stock is really worth from its fundamentals, not its daily price. For 40,000+ stocks worldwide it shows a fair value, a quality score and how much evidence backs each estimate, so you can spot over- and undervalued companies at a glance. See the methodology →

How is a stock's fair value calculated?

We estimate a company's intrinsic worth from 26 independent valuation models running on its reported financials, then blend them into one figure weighted by how much trustworthy data backs it. That way the result never hangs on a single formula. See the methodology →

What can I use for free?

Browsing, searching and seeing fair values is free and needs no sign-up. The full analysis, with every valuation model and the history, is open for 8 stocks a month without an account and 13 with a free account. You also get a free watchlist: 5 stocks without an account, 10 with one.

What additional features are included with Pro?

Pro ($9.90 per month or $99 a year, first month $1) adds the full screener across 27,000+ stocks, watchlist alerts when a holding flips to Review, diversification and market-valuation checks, and every quality factor. You can cancel anytime. See Pro →

Is fair value a buy recommendation?

No. A fair value is an analytical estimate of what a business is worth, not advice to buy, hold or sell. It is a starting point for your own research. Nothing on the site is financial advice, and past results are no guarantee of future outcomes.
