Investing in stocks can feel like trying to guess the winning lottery numbers, but it doesn’t have to. Valuation metrics are here to save the day. Think of them as a map that shows whether a stock is a hidden gem, overpriced hype, or something in between.
Today, we’re cracking open six essential metrics—price-to-book, price-to-earnings, price-to-sales, price-to-free cash flow, earnings yield, and dividend yield—explained with clarity and some spice.
1. Price-to-Book (P/B) Ratio
Formula: P/B = stock price / book value per share
The P/B ratio helps you determine if you’re paying too much for a company’s net assets (think of it as the stuff the company owns minus what it owes). A low P/B ratio—usually below 1—might suggest the stock is undervalued compared to its tangible assets, but it could also mean the company is struggling. This metric is especially handy for asset-heavy industries like banking or real estate.
For example, XYZ Corp.’s stock trades at $50, and its book value per share is $25. Divide $50 by $25, and you get a P/B of 2. This means investors are paying $2 for every $1 of XYZ’s net assets. If similar companies have a P/B of 1.5, XYZ might be overvalued. If its P/B is below 1, it could signal a potential bargain—or a red flag worth investigating further.
2. Price-to-Earnings (P/E) Ratio
Formula: P/E = stock price / earnings per share (EPS)

The P/E ratio shows how much you’re paying for each dollar of a company’s earnings. This is one of the most widely used valuation metrics because it tells you if the market thinks a company has big growth potential—or if it’s just plain expensive. A higher P/E often reflects optimism about future growth, while a lower P/E might indicate a bargain or slow growth.
If XYZ’s stock price is $50 and its earnings per share is $5, the P/E ratio is $50 divided by $5, or 10. This means investors are willing to pay $10 for every $1 of earnings. If the average P/E in XYZ’s industry is 20, it could mean XYZ is undervalued—or that it lacks the growth prospects of its competitors.
3. Price-to-Sales (P/S) Ratio
Formula: P/S = stock price / revenue per share (or P/S = market capitalization / total revenue)
The P/S ratio tells you how much you’re paying for each dollar of revenue the company generates. It’s particularly useful for evaluating startups or companies that aren’t profitable yet. A lower P/S can indicate an undervalued stock, but revenue growth trends are crucial to consider.
Let’s say XYZ has a market cap of $500 million and annual revenue of $250 million. Divide $500 million by $250 million, and you get a P/S ratio of 2. Investors are paying $2 for every $1 of revenue. If competitors have a P/S closer to 3 or 4, XYZ could be a bargain. If sales are declining, however, even a low P/S might not save the day.
4. Price-to-Free Cash Flow (P/FCF) Ratio
Formula: P/FCF = stock price / free cash flow per share (or P/FCF = market capitalization / total free cash flow)
The P/FCF ratio shows how much you’re paying for a company’s free cash flow—the money left over after expenses and investments. Free cash flow is crucial because it funds dividends, debt repayment, and growth initiatives. A lower P/FCF can signal a strong cash position or an undervalued stock.
If XYZ generates $50 million in free cash flow and has a market cap of $500 million, the P/FCF is $500 million divided by $50 million, or 10. This means investors are paying $10 for every $1 of free cash flow. A P/FCF below 15 is generally considered good, and if XYZ’s competitors have a P/FCF of 20 or higher, this could suggest XYZ is a better value.
5. Earnings Yield
Formula: Earnings yield = earnings per share / stock price (or earnings yield = 1 / P/E ratio)
Earnings yield flips the P/E ratio and expresses earnings as a percentage of the stock price. This makes it easier to compare stocks to bond yields or market averages. A higher earnings yield might signal a better value, especially if it beats the return on safer investments like Treasury bonds.
If XYZ has a P/E ratio of 10, its earnings yield is 1 divided by 10, or 10%. For every $100 you invest in XYZ, the company generates $10 in earnings. If Treasury bonds yield 4%, XYZ might look like a better investment—assuming its earnings are stable or growing.
6. Dividend Yield
Formula: Dividend yield = annual dividend per share / stock price
The dividend yield tells you how much income you’re getting from a stock in the form of dividends. It’s a favorite for income-focused investors who want consistent cash flow. A high dividend yield can be attractive, but watch out—unsustainable payouts might signal financial trouble.
If XYZ pays an annual dividend of $2 per share and its stock trades at $50, the dividend yield is $2 divided by $50, or 4%. That’s $4 in annual income for every $100 you invest. If competitors have a yield of 3%, XYZ might be a better choice—but only if it can keep paying those dividends.
Final Thoughts
These valuation metrics are like a financial X-ray, showing you the true value of a company beyond the hype. Use them to compare stocks within the same industry, dig into what the numbers are telling you, and understand what you’re really paying for. Master these, and you’ll be analyzing stocks like a pro in no time.
