Book Value Per Share: Formula, Calculation & Examples
How to Calculate Book Value Per Share: Step-by-Step
Here is how to calculate book value per share using a practical example:
Step 1: Find total shareholders equity on the balance sheet. Suppose a company reports total assets of $500 million and total liabilities of $300 million. Total equity equals $200 million.
Step 2: Subtract any preferred stock. If the company has $20 million in preferred stock, subtract that from total equity. The remaining equity for common shareholders is $180 million.
Step 3: Divide by the number of shares outstanding. If the company has 50 million common shares outstanding, the book value per share equals $180 million divided by 50 million equals $3.60 per share.
This means each share of common stock is backed by $3.60 in net asset value according to the balance sheet.
Book Value Per Share vs. Market Price
One of the most important uses of BVPS is comparing it to the current stock price. This comparison reveals whether a stock is trading above or below its book value, which can signal potential investment opportunities.
When the market price is below book value per share, the stock may be undervalued. Value investors like Benjamin Graham specifically looked for stocks trading below their net asset value as potential bargains. A stock price below BVPS suggests the market is valuing the company at less than its liquidation value.
When the stock price is significantly above BVPS, the market is pricing in future growth, brand value, intellectual property, or other intangible assets that do not appear on the balance sheet at historical costs. Technology companies often trade at many multiples of book value because their most valuable assets are not reflected in traditional accounting.
The Price-to-Book ratio formalizes this comparison. A P/B below 1.0 means the stock trades below book value, while a P/B above 1.0 means it trades at a premium.
Why Book Value Per Share Matters for Value Investors
BVPS serves several critical functions for investors evaluating a company stock.
Floor Valuation: Book value provides a theoretical floor for a company stock price. If a company assets can be sold for at least their balance sheet values, shareholders should receive at least the BVPS in a liquidation scenario.
Identifying Undervalued Stocks: Stocks trading below book value may represent opportunities where the market has overly discounted a company assets. This is especially relevant for asset-heavy industries like banking, insurance, and real estate where balance sheet values closely reflect actual asset worth.
Tracking Equity Growth: Rising BVPS over time indicates that a company is building shareholder value by growing its total equity through retained earnings, reducing liabilities, or both.
Comparing Companies: Within the same industry, BVPS allows investors to compare how efficiently companies deploy their assets on a per-share basis.
Limitations of Book Value Per Share
While BVPS is a valuable metric, it has important limitations that investors should understand.
Historical Costs: Balance sheet assets are typically recorded at historical costs rather than current market values. A piece of real estate purchased decades ago may be worth far more than its book value suggests, while some assets like equipment may have depreciated below their actual resale value.
Intangible Assets: Many of the most valuable company assets including brand recognition, patents, customer relationships, and proprietary technology are intangible assets that may not appear on the balance sheet at all. This makes BVPS less meaningful for asset-light businesses with significant intellectual property.
Industry Differences: BVPS is most useful for capital-intensive industries where a company assets are primarily tangible such as banks, manufacturers, and utilities. For technology or service companies where value comes from intangible assets and human capital, BVPS may significantly understate true value.
Share Buybacks and Dilution: Companies that aggressively buy back shares can artificially inflate BVPS, while those issuing new shares for acquisitions or employee compensation may dilute it.
A variation of BVPS that some investors prefer is tangible book value per share. This metric excludes all intangible assets like goodwill and patents from the calculation, focusing only on physical, tangible assets.
Tangible BVPS equals Total Equity minus Preferred Stock minus Intangible Assets, divided by Shares Outstanding.
Tangible book value provides an even more conservative estimate of what shareholders would receive in liquidation, since intangible assets often have little or no value in a distressed sale. This is particularly useful when analyzing companies that have made large acquisitions that resulted in significant goodwill on their balance sheet.
Real-World Example: Calculating BVPS
Consider a hypothetical manufacturing company with these balance sheet figures. Total assets: $1.2 billion. Total liabilities: $700 million. Preferred stock: $50 million. Intangible assets: $100 million. Common shares outstanding: 100 million.
Standard BVPS equals $1.2B minus $700M minus $50M, divided by 100M, which equals $4.50 per share.
Tangible BVPS equals $1.2B minus $700M minus $50M minus $100M, divided by 100M, which equals $3.50 per share.
If this company stock price is $3.00, it trades below both book value and tangible book value, a potential signal that the market is undervaluing the company assets.
How to Use BVPS in Your Investment Analysis
To incorporate book value per share into your investment process effectively, compare BVPS to the current stock price using the P/B ratio. Look for companies trading near or below book value in sectors where tangible assets drive value creation.
Track BVPS trends over time. Companies that consistently grow their book value per share are building real shareholder equity, while declining BVPS may indicate value destruction through losses or excessive share dilution.
Use BVPS alongside other valuation metrics like earnings per share, return on equity, and free cash flow. No single metric tells the whole story, but BVPS provides a solid foundation for understanding what the balance sheet says about a company worth.
Tools like ValueMarkers make it easy to screen for stocks trading below book value and compare BVPS across companies in the same industry, helping you identify potential value opportunities quickly.

Frequently Asked Questions
What is a good book value per share value?
What counts as a good book value per share value depends on the industry and company type. Comparing a company's book value per share to its industry peers and its own historical range provides the most meaningful context. ValueMarkers calculates percentile rankings across all stocks so investors can see exactly where a company falls relative to the broader market.
How do I calculate book value per share?

What does book value per share tell investors?
The book value per share provides insight into a specific aspect of company performance, whether that relates to valuation, profitability, financial health, growth, or risk.

How do I interpret book value per share correctly?
