Book value is a fundamental financial metric used to assess the net worth of a company or asset based on accounting records. It is calculated as the difference between total assets and total liabilities listed on the balance sheet, a key financial statement. This measure provides an estimate of the value that remains for shareholders after all obligations are paid.
How to Calculate Book Value
The standard formula for book value is:
Book Value = Total Assets – Total Liabilities
- Total Assets include cash, inventory, property, equipment, and other tangible and intangible value items recorded.
- Total Liabilities cover debts, loans, accounts payable, and other financial obligations.
Because assets on the balance sheet are typically recorded at original costs minus depreciation (rather than current market values), book value can differ significantly from what the business or asset might sell for in the market.
Why Book Value Matters
Book value offers a conservative measure of a company’s net worth and is useful for various stakeholders:
- Investors: It helps identify undervalued stocks by comparing book value per share to the market price, signaling investment opportunities.
- Creditors and Lenders: They assess financial stability and collateral value through book value analysis to make informed lending decisions.
- Management: Provides insight into the company’s financial health and equity available to shareholders.
Book Value vs. Market Value
A critical distinction is between book value and market value:
- Book Value is accounting-based and uses historical costs minus liabilities.
- Market Value reflects the current stock price multiplied by outstanding shares, influenced by future profits, market trends, and investor sentiment.
Many companies, especially those in technology or with significant intangible assets like intellectual property, will have market values much higher than their book values.
Example to Illustrate
Consider a business with $1 million in assets and $600,000 in liabilities. The book value is:
$1,000,000 – $600,000 = $400,000
This represents the net asset value on paper. However, the market might value this company differently based on growth potential or risks.
Limitations of Book Value
- Historical Cost Bias: Assets are valued at purchase price, less depreciation — not current value.
- Intangible Assets: Often understated or excluded; things like brand reputation, patents, or goodwill may not be fully captured.
- Negative Book Value: If liabilities exceed assets, it indicates financial distress.

Practical Tips
- Use book value as a reality check against market price but also review earnings, cash flow, and intangible asset considerations.
- Be cautious with industries heavy in intellectual property, where book value may undervalue true worth.
Frequently Asked Questions
Can book value be negative? Yes, if liabilities outstrip assets, book value becomes negative, signaling possible financial trouble.
What is book value per share? It’s the company’s book value divided by its total outstanding shares, indicating net asset value attributable to each share.
Does book value include goodwill? Goodwill and other intangibles may be included in assets but can distort the true economic value if improperly valued.
