Balance-Sheet Strength
Shows the relationship between a company’s recorded assets and liabilities.
What Is Book Value?
Book value is the accounting value of a company’s net assets, calculated by subtracting its total liabilities from its total assets, using the relevant balance-sheet figures.
Book Value = Total Assets − Total Liabilities
- It is based on accounting records, not on market trading.
- It represents net assets according to the applicable accounting figures.
- It may differ from what a company could receive by selling all its assets.
- It changes as assets, liabilities and equity change.
- It is not the same as market capitalization.
HYPOTHETICAL EXAMPLE
Total Assets₹50 crore
Total Liabilities₹20 crore
Book Value₹30 crore
Calculation: ₹50 crore − ₹20 crore = ₹30 crore
What Is Book Value Per Share?
Book value per share expresses the relevant shareholders’ equity on a per-share basis, so it can be compared with a single share’s market price.
Book Value Per Share = Equity Attributable to Ordinary Shareholders ÷ Ordinary Shares Outstanding
- Use the equity figure that belongs to ordinary shareholders.
- Use a share count that matches the equity figure and reporting basis.
- Preferred equity, where applicable, may need to be excluded.
- Basic book value per share can differ from tangible book value per share.
HYPOTHETICAL EXAMPLE
Equity (Ordinary Shareholders)₹30 crore
Ordinary Shares Outstanding3 crore
₹30 crore ÷ 3 crore shares =
₹10 per share

Sector Context
It may be more relevant for asset-heavy businesses and financial institutions, and less informative where intangibles or future growth drive value.
Book Value vs Market Price
Book value per share comes from financial statements. Market price comes from trading. The two are often different.
Book Value Per Share
- Based on accounting equity and share count
- Calculated from financial statements
- Changes as the relevant accounting figures change
- Does not directly measure current investor demand
Market Price Per Share
- The price at which a share trades in the market
- Changes with demand, supply, expectations, performance and market conditions
- May be above or below book value per share
- Reflects what market participants are currently willing to pay
HYPOTHETICAL EXAMPLE
Book value per share is ₹100 and market price per share is ₹80. The price is 0.8 times book value per share. This alone does not show that the share is undervalued. Investors may be weighing profitability, asset quality, future growth, liabilities or business risks.
Price-to-Book (P/B) Ratio
The P/B ratio compares a share’s market price with its book value per share.
P/B Ratio = Market Price Per Share ÷ Book Value Per Share
- Below 1: market price is below book value per share.
- Above 1: market price is above book value per share.
- Neither result automatically means a stock is cheap or expensive.
- Interpretation depends on sector, asset quality, profitability, growth outlook, accounting methods and risks.
- P/B is generally more useful for some types of businesses than others.
HYPOTHETICAL EXAMPLE
Market Price Per Share₹80
Book Value Per Share₹100
₹80 ÷ ₹100 =
P/B Ratio = 0.8
Book Value vs Face Value vs Market Capitalization
These three figures measure different things and are usually different numbers.
| Book Value | Face Value | Market Capitalization |
|---|---|---|
| Based on recorded assets minus liabilities | Nominal value assigned to a share | Market price per share × total shares outstanding |
| Represents accounting net worth at company level | Part of the company’s share-capital structure | Reflects the market value of outstanding equity |
| Book value per share expresses relevant equity per ordinary share | Not a measure of current net assets | Changes as share price and share count change |
| Hypothetical: ₹30 crore total (₹10 per share) | Hypothetical: ₹2 per share | Hypothetical: ₹25 × 3 crore shares = ₹75 crore |
Total company book value (₹30 crore) is not the same as book value per share (₹10).
Common Book Value Mistakes
Book value ≠ market price
Book value is an accounting figure; the price is set by trading.
Not guaranteed sale value
Recorded asset values may differ from what they would fetch if sold.
Below book ≠ undervalued
A low P/B can reflect real concerns about earnings or asset quality.
Ignoring liabilities and asset quality
Look at what the assets are and how reliably they are valued.
Comparing unrelated sectors
Banks, manufacturers and software firms have very different asset structures.
Total vs per share
Company-level book value and book value per share are different figures.
Book Value Per Share Calculator
Enter figures in the same currency unit, and choose the share-count unit separately. Defaults are a hypothetical example.
Calculated Book Value (Assets − Liabilities)—
Entered Ordinary Shareholders’ Equity—
Ordinary Shares Outstanding—
Book Value Per Share—
Preferred equity, minority interests and other accounting adjustments can make ordinary shareholders’ equity differ from assets minus liabilities.
This calculator is an educational simplification. Actual book value per share depends on the relevant reported equity, share count and accounting adjustments.
Myths vs Facts
Myth: Book value is the price at which a share trades.
Fact: Book value is based on accounting equity, while market price is determined by market trading.
Myth: A stock trading below book value is always a bargain.
Fact: A low price-to-book ratio can reflect risks, poor profitability, asset-quality concerns or market expectations.
Myth: Book value equals the cash a company could receive by selling all its assets.
Fact: Accounting book value does not necessarily equal liquidation proceeds or the current market value of assets.
Myth: Book value and face value mean the same thing.
Fact: Book value is based on net assets and equity; face value is the nominal value assigned to a share.
Frequently Asked Questions
Book value is a company’s accounting net worth: total assets minus total liabilities. In the stock market, investors often look at book value per share and compare it with the share’s market price as one input among many.
Divide the equity attributable to ordinary shareholders by the number of ordinary shares outstanding. For example, ₹30 crore ÷ 3 crore shares = ₹10 per share. Make sure the equity figure and share count are on the same basis.
Not automatically. A price below book value per share can reflect weak profitability, asset-quality concerns, liabilities or other risks. It is one data point and should be studied alongside other financial information and your own research.
Book value reflects a company’s net assets and equity from its accounting records. Face value is the nominal value assigned to each share and is part of the share-capital structure. It does not measure current net assets.
