Book value per share (BVPS) tells investors how much of a company's net assets each share represents. It offers a grounded, asset-based perspective on what a share is worth independent of market sentiment or earnings expectations.
Definition of Book Value Per Share
Book value per share represents the net asset value of a company on a per-share basis. It equals total shareholders' equity divided by the number of shares outstanding.
In practical terms, BVPS answers a simple question: if this company were liquidated today and all assets sold at their recorded values, how much would each shareholder receive after all debts were paid? The result is a floor estimate based purely on the balance sheet, without accounting for future earnings, brand value, or growth.
One important distinction: BVPS is derived from historical accounting data. Assets are recorded at purchase price minus depreciation, not at current market value. So BVPS reflects what the company paid for its assets, not what they would sell for today.
BVPS Formula and Example
BVPS = (Total Assets - Total Liabilities) / Shares Outstanding
Since total assets minus total liabilities equals shareholders' equity, this can also be written as total shareholders' equity divided by shares outstanding.
Worked example
Consider a company with total assets of $50 billion, total liabilities of $30 billion, and 2 billion shares outstanding. Shareholders' equity equals $20 billion, giving a BVPS of $10 per share.
If this stock trades at $15, the market is valuing it at 1.5 times book value. If it trades at $8, the market is pricing it below book value.
Tangible book value
Some analysts exclude intangible assets like goodwill and patents to get tangible book value per share. This is more conservative because intangibles can be difficult to value in a liquidation scenario. For acquisition-heavy companies, the gap between book value and tangible book value can be substantial.
Book Value vs Market Value
Book value and market value measure different things.
Book value reflects historical cost, telling you what the company's net assets are worth on paper. Market value reflects investor expectations, pricing in future earnings and growth that do not appear on the balance sheet.
The price-to-book ratio captures this relationship. A P/B above 1 means the market values the company above book value. A P/B below 1 means the stock is priced below its stated net assets.
- Market value far above book value suggests investors believe the company's earning power justifies a premium. Tech companies routinely trade at 5 to 15 times book value because their real value lies in intellectual property, not physical assets.
- Market value below book value can signal declining profitability or structural problems. But it can also indicate a value stock temporarily mispriced due to sentiment or sector-wide selling.
The relationship must be interpreted within the context of the company's business model and industry.

When BVPS Matters Most
BVPS is not equally useful across all sectors. It provides the most insight where balance sheet assets are central to the business.
Financial sector analysis
Banks and insurance companies hold portfolios of loans, securities, and cash recorded at values closely tied to their economic worth.
BVPS and P/B ratios are primary tools for valuing financials, making them a direct way to assess whether a bank appears cheap or expensive relative to peers.
Asset-heavy industries
Companies in real estate, manufacturing, utilities, and natural resources own substantial physical assets with recoverable worth. When market prices fall below BVPS in these sectors, it can signal genuine undervaluation.
Distressed or restructuring situations
When a company faces financial difficulty, investors look to book value as a measure of downside protection.
Value investors sometimes use BVPS as a screening filter to find companies where asset value provides a margin of safety.
Limitations of Book Value
Despite its simplicity, BVPS has significant limitations that investors must understand.
- Intangible assets are underrepresented. Companies driven by intellectual property or brand equity will always appear expensive on a book value basis, making BVPS misleading for tech or pharma stocks.
- Historical cost distorts reality. A building purchased 20 years ago may be worth far more than its book value, while specialized equipment may be worth less.
- Goodwill can inflate book value. Acquisitions at a premium create goodwill that inflates BVPS, but may need to be written down if the deal underperforms.
- Share dilution affects the denominator. New share issuances reduce BVPS even if total equity stays the same.
- BVPS alone does not predict returns. A stock below book value is not automatically a good buy. Using BVPS within a broader fundamental analysis framework alongside fair value estimates produces better outcomes.
Conclusion
Book value per share measures the net asset backing behind each share. It is most valuable in asset-heavy industries like banking and real estate, and least useful for asset-light businesses driven by intangible value.
Understanding the formula, knowing when it provides genuine insight, and respecting its limitations helps investors use BVPS as one reliable input within a broader framework.
FAQ
What is book value per share?
Book value per share is a company's total shareholders' equity divided by its shares outstanding. It represents the net asset value attributable to each share based on balance sheet data.
Is a stock trading below book value a good buy?
Not necessarily. It can signal undervaluation, but it can also reflect concerns about asset quality, profitability, or business viability. Further analysis is always required.
Which industries is BVPS most useful for?
Banks, insurance companies, real estate firms, and other asset-heavy businesses where balance sheet assets closely represent economic value.
