Book value is the recorded accounting equity left after a company subtracts total liabilities from total assets. For a company, the figure generally corresponds to the equity recorded on the balance sheet.
It provides a balance-sheet reference point. Market value and intrinsic value answer different questions because they are not determined by the accounting equity balance alone.
Book Value Formula
Book Value = Total Assets – Total Liabilities
If a company reports $120 million in total assets and $75 million in total liabilities, its book value is $45 million. The calculation describes recorded accounting equity at that reporting date.
Where Book Value Comes From on the Balance Sheet
For company analysis, book value is closely tied to shareholders’ equity. The equity section can include contributed capital, retained earnings, treasury-stock adjustments, accumulated other comprehensive income, and other equity accounts.
The composition matters. Two companies can report similar book value while reaching that balance through different histories of retained profits, losses, distributions, buybacks, issuance, write-downs, or other accounting changes.
Company Book Value and Asset Carrying Value
| Use of book value | What it refers to | Analytical boundary |
|---|---|---|
| Company book value | The recorded residual equity after total liabilities are deducted from total assets. | It describes the company-level accounting equity base. |
| Asset carrying value | The amount at which a specific asset is recorded after applicable accounting adjustments. | The recorded amount can differ from the asset’s current economic or market value. |
Book Value vs Market Value
The two figures can differ because market pricing reflects expectations about future earnings, profitability, risk, asset quality, and other economic value that may not be captured by the recorded equity balance.
Comes from recorded assets, liabilities, and the resulting accounting equity.
Comes from the current share price and the equity value assigned by the market.
Book Value Per Share and Tangible Book Value
Book value per share translates common book equity into a per-share measure by combining the relevant equity balance with share-count information.
Tangible book value removes specified intangible assets from the recorded equity base. It answers a narrower balance-sheet question and can produce a materially different reference point when goodwill or other recognized intangibles are significant.
Limits of Book Value
Historical cost, depreciation, amortization, impairment, goodwill, and the recognition rules for internally generated intangible assets can all affect the relationship between book value and the economics of the business. A stock trading below book value can therefore reflect asset problems, weak profitability, expected losses, or poor capital allocation rather than a clear valuation opportunity.
How to Read Book Value in Context
| Analytical question | Why it changes the reading |
|---|---|
| What created the equity balance? | Retained profits, losses, distributions, buybacks, issuance, and accounting adjustments can produce very different equity histories. |
| How economically relevant are the recorded assets and liabilities? | Asset quality, write-down risk, accounting values, and unrecognized internally generated intangibles can change how informative the headline number is. |
| What returns does the business earn on the equity base? | Book value becomes more useful when it is read alongside profitability, cash generation, leverage, and capital allocation rather than as a valuation conclusion by itself. |
