Book Value
Book value is a simple way to describe a company's net assets using figures reported in its financial statements.
Start the lessonIntroduction
A snapshot of recorded net assets
A company owns assets such as cash, equipment, and inventory, and it also owes money and other obligations. In a simplified view, book value is the value of assets minus liabilities as recorded in the company's accounts. It is often described as shareholders' equity, though the precise figure used can depend on preference shares, non-controlling interests, and the question being asked.
Think of it as an accounting snapshot—not a live valuation.
Share prices change with market expectations. Balance-sheet values are prepared under accounting rules and may not equal what assets could be sold for today.
The calculation
Subtract liabilities from assets
Book Value = Total Assets − Total Liabilities
To calculate a simplified book value per share, divide the book value attributable to ordinary shareholders by the relevant number of ordinary shares. Financial data sources may make adjustments, so check their definitions and use figures from the same reporting date.
Book Value per Share = Book Value Attributable to Ordinary Shareholders ÷ Ordinary Shares
Interactive example
Try a simple ₹10 lakh example
Enter illustrative balance-sheet values and a share count to see book value and book value per share.
Illustrative calculation
Book value: ₹4,00,000
Book value per share: ₹20
(₹10,00,000 assets − ₹6,00,000 liabilities) ÷ 20,000 shares
This simplified example does not account for preference shares, non-controlling interests, or other adjustments. It is illustrative, not data from a specific company.
In context
Useful information, with limits
- Book value can help describe the net assets shown on a balance sheet at a particular date.
- Compare book value across time and with similar businesses, while checking for changes in accounting policies and business structure.
- A company's market value may be higher or lower than book value because investors also consider expected earnings, risks, growth, and intangible assets.
- Recorded asset amounts may differ from current market or resale values; book value is not automatically liquidation value.
- For a P/B ratio, analysts often use book value per share. A zero or negative book value can make the conventional ratio difficult to interpret.
- Check whether a figure is consolidated or standalone and whether it is attributable to ordinary shareholders.
Common mistakes
Avoid treating book value as a price target
Confusing it with market value
Book value comes from accounting records; market value reflects the price investors currently assign.
Assuming assets can be sold at book value
The amount recovered from selling assets may differ, and winding up a business can involve costs and other claims.
Ignoring the share count
Book value per share changes when the share count changes, even if total book value does not.
Using one number without context
Review profitability, debt, cash flows, asset quality, and the company's industry as well.
Key points
What to remember
- Simplified book value is assets minus liabilities.
- Book value per share divides the relevant equity amount by the ordinary share count.
- Book value is based on accounting figures at a reporting date.
- It is not the same as market value or guaranteed sale proceeds.
- Definitions and adjustments can differ between data sources.
- Use it with other financial information and business context.
