Book Value: Formula, Book Value per Share, and Example
What shareholders would own on paper if the company sold its assets and paid its debts. It is calculated straight from the balance sheet — total assets minus total liabilities — and dividing by the share count gives book value per share, the anchor for the price-to-book ratio.
The book value formula
Book value = total assets − total liabilities. Both numbers come straight off the balance sheet, and the result is the same line accountants call shareholders' equity: what would be left for shareholders, on paper, after everything owed is paid.
Book value per share (BVPS) = book value ÷ shares outstanding. Price-to-book (P/B) = share price ÷ book value per share — the ratio that compares what the market charges for the company against what the accounting says it is worth.
Tangible book value goes one step stricter: it subtracts intangible assets — goodwill from past acquisitions, brands, patents — leaving only assets with a hard resale value. Lenders and bank analysts usually work from the tangible number.
A worked example
A hypothetical manufacturer's balance sheet shows $500 million of assets and $300 million of liabilities.
- Book value = $500M − $300M = $200 million.
- With 50 million shares outstanding, book value per share = $200M ÷ 50M = $4.00.
- At a stock price of $8.00, price-to-book = $8.00 ÷ $4.00 = 2.0 — the market prices the company at twice its on-paper worth.
- If $100M of the assets are goodwill from an old acquisition, tangible book value is $100M — $2.00 per share — and the same $8.00 stock trades at 4.0× tangible book.
The same company can look twice as expensive depending on which book value is used. The composition of the assets matters as much as the total — which is why the number needs the balance sheet behind it.
Book value vs market value
Market value — the market cap — is what the market says the company is worth today; book value is what the accounting records say. The gap between them is the market's verdict on everything the balance sheet cannot hold: future earnings power, brands built rather than bought, network effects, or looming losses.
A stock trading below book value (P/B under 1) is priced as if the company is worth more dismantled than operating — sometimes a genuine bargain, more often the market doubting that the assets would fetch their stated values or that the business can earn a decent return on them.
The ratio's meaning is sector-relative. Banks and insurers are analyzed on book value because their assets are financial and marked close to reality; software and consumer-brand companies routinely trade at many times book because their most valuable assets — code, brands, customer relationships built in-house — barely appear on the balance sheet at all.
Where book value misleads
Book value records what assets cost, not what they are worth. Real estate bought decades ago sits at old cost; specialized equipment may be unsellable at its carrying value; goodwill reflects the price paid for past acquisitions, which says nothing about their value now.
For modern asset-light businesses, book value can be close to meaningless — years of research and brand-building are expensed as they happen, so they never accumulate as assets. Heavy buybacks can even push accounting equity negative while the business itself stays healthy, because repurchases reduce equity regardless of how the company is performing.
Book value vs adjacent terms
Market cap — Market cap is the market's live price for the whole company; book value is the accounting residual on the balance sheet. Comparing them — the price-to-book ratio — asks how much of the price rests on things the accounting cannot see.
Balance sheet — The balance sheet is the full snapshot of what the company owns and owes; book value is one derived line of it — the difference between the two sides. A book value figure is only as trustworthy as the asset values feeding it.
Fair value — Fair value is an analytical judgment of what the business is worth as a going concern, usually anchored on its future cash flows. Book value is a backward-looking accounting total; the two can sit far apart for entirely legitimate reasons.
Why this term matters
Financial-statement terms describe how the business itself is doing — how much money comes in, what survives the costs, and how much cash is really left at the end.
In a Monsaic report, you’ll meet book value in the “Current outlook” section of the simplified read, and the Fundamentals and Balance Sheet analyses of the full report. Inside a report, tapping any underlined term shows this same definition in place — the reading never has to stop for a search.
How Monsaic uses the balance sheet
A Monsaic report works through the balance sheet in its Fundamentals and Balance Sheet analyses — what the company owns, what it owes, and how solid the residual is — rather than quoting a single book-value figure out of context.
Balance-sheet claims in a report carry claim-level citations to the filing they came from, so a stated asset or equity figure can be traced to its source.

FAQ
What is the formula for book value?
Book value = total assets minus total liabilities, both taken from the balance sheet. The result equals shareholders' equity: what shareholders would own on paper if the company sold its assets at their recorded values and settled every obligation.
What is book value per share?
Book value per share (BVPS) is book value divided by shares outstanding — the accounting worth attached to each share. Comparing it with the share price gives the price-to-book ratio; a $4.00 book value per share against an $8.00 stock is a P/B of 2.0.
What is the difference between book value and market value?
Book value is what the accounting records say the company is worth; market value (market cap) is what the market is paying for it today. The gap reflects everything the balance sheet cannot capture — future earnings, home-grown brands and technology, or expected losses.
What is tangible book value?
Tangible book value is book value minus intangible assets such as goodwill, brands, and patents. It answers a stricter question — what would the hard assets cover — and is the version lenders and bank analysts usually rely on.
What is a good price-to-book ratio?
There is no universal threshold — the ratio is sector-relative. Banks and insurers are judged near book value because their assets are financial and marked close to market; asset-light software or brand companies routinely trade at many times book because their key assets never appear on the balance sheet. A P/B below 1 signals the market doubts the stated asset values or the returns earned on them.
