What Is Book Value Per Share (BVPS)?
What Is Book Value Per Share (BVPS)?
Book value per share tells you what a company would theoretically be worth, per share, if it sold off everything it owns and paid off everything it owes. It's the other half of what feeds into the Graham Number, alongside earnings per share, and it comes at valuation from a completely different angle: not what the company earns, but what it actually owns.
Where EPS is about profit, BVPS is about net worth. A company can have a bad year and post weak earnings while still sitting on a solid pile of real assets, and BVPS is the number that captures that second part.
How It's Calculated
BVPS = Shareholder Equity ÷ Shares Outstanding
Shareholder equity is what's left over on a company's balance sheet after subtracting everything it owes (liabilities) from everything it owns (assets). You'll sometimes see it called "net assets" or simply "equity," and it's reported directly on the balance sheet in every company's financial statements, so you don't need to calculate it yourself. Shares outstanding is the same figure used in the EPS calculation, the total number of shares currently held by all investors.
Take a company with €180 million in shareholder equity and 10 million shares outstanding:
€180,000,000 ÷ 10,000,000 = €18.00 per share
That €18.00 is the BVPS figure that plugs into the Graham Number formula.
What BVPS Is Really Measuring
Book value comes from accounting records, not from the market. It reflects what the company's assets are worth on paper, based on what they originally cost (sometimes adjusted for depreciation), not what they'd actually fetch if sold today or what the market thinks the business is worth as a going concern.
That distinction matters. A stock trading below its BVPS is sometimes described as trading "below book," which value investors have historically treated as a signal of a potential bargain, the idea being you could theoretically buy the whole company for less than its assets are worth on paper. A stock trading well above its BVPS is described as having a high price-to-book ratio, common for companies whose real value lies in things the balance sheet doesn't fully capture, like a strong brand or a growing customer base.
BVPS also says nothing about how profitably that book value is being put to work, which is what return on equity measures.
Where BVPS Gets Distorted
A few things can make BVPS a less reliable number than it looks.
Intangible assets are the biggest one. Modern companies often carry significant value in things like brand reputation, software, patents or acquired goodwill, and accounting rules don't always capture these the same way they capture a factory or a piece of equipment. Two companies can be worth wildly different amounts in the real world while showing similar book values, simply because one holds more of its value in things the balance sheet undercounts.
Share buybacks also affect the number. When a company buys back its own shares, it typically reduces shareholder equity while also reducing shares outstanding, and depending on the price paid for those shares, BVPS can move in ways that don't reflect any real change in the underlying business.
And book value is backward-looking by nature. It reflects historical costs recorded on the balance sheet, not current market prices, which is why a company's real estate, for example, might be worth far more (or less) today than the figure still sitting on its books.
