What is the Book Value of a Share? Explain in Simple Words
Book value of a share is the value of a company’s assets (things it owns) minus its liabilities (what it owes), divided by the number of shares.
It tells you what each share would be worth if the company was closed down and all its assets were sold and debts paid off.
Think of it like this:
Imagine a bakery. It owns ovens, furniture, ingredients, and has some cash in the bank. But it also has loans. If you subtract the loans from the total value of everything the bakery owns, you get the book value of the business. If the bakery is owned by 10 people (10 shares), divide the book value by 10 to get the book value per share.

- Find the company’s balance sheet (from its financial statements or websites like Yahoo Finance, Moneycontrol, etc.)
- Use this formula:
Example:
- Example:
- Total Assets = ₹500 crore
- Total Liabilities = ₹200 crore
- Outstanding Shares = 10 crore
So, the book value of each share is ₹30.
What Is an “Ideal” Book Value for a Good Company?
There’s no one-size-fits-all number, but you can use Book Value in combination with the stock price to make decisions.
Look at the Price-to-Book Ratio (P/B Ratio):
P/B Ratio=Market Price per ShareBook Value per Share\text{P/B Ratio} = \frac{\text{Market Price per Share}}{\text{Book Value per Share}}P/B Ratio=Book Value per ShareMarket Price per Share
- P/B < 1: Stock is selling for less than its book value – could be undervalued (but investigate why).
- P/B = 1–3: Usually seen in fairly valued or moderately growing companies.
- P/B > 3: High growth or overvalued – be cautious and look deeper.
Ideal P/B Ratio for Investment:
- For value investors, a P/B ratio below 1 or 1.5 may be attractive.
- For growth companies, even a P/B of 3 or more can be okay if earnings and future potential are strong.
Summary:
| Term | Simple Meaning |
|---|---|
| Book Value | Company’s total net worth (assets – liabilities) |
| Book Value per Share | Net worth divided by total number of shares |
| Ideal P/B Ratio | Around 1–1.5 for safe value investments (lower is better, but not always good) |
