A company’s balance sheet says it is worth ₹800 crore. The stock market says ₹6,000 crore. Neither is lying. They are answering different questions, and understanding the gap between them is one of the more useful skills in reading financial statements.
What is Book Value?
Book value is what a company is worth according to its accounting records — total assets minus total liabilities.
Book Value = Total Assets − Total Liabilities
It is also called shareholders’ equity or net worth. Conceptually it answers: if the company sold everything at the values recorded in its books and paid off every debt, what would be left for shareholders?
The figure sits directly on the balance sheet under “Total Equity” or “Shareholders’ Funds”, so you rarely need to calculate it yourself.
Book Value Per Share
To compare against a share price, convert book value to a per-share figure:
Book Value Per Share = Total Book Value ÷ Number of Outstanding Shares
A worked example:
| Item | Amount |
|---|---|
| Total assets | ₹1,200 crore |
| Total liabilities | ₹400 crore |
| Book value (equity) | ₹800 crore |
| Shares outstanding | 10 crore |
| Book value per share | ₹80 |
If this share trades at ₹240 in the market, it is priced at three times its book value — a P/B ratio of 3.
What Sits Inside Book Value
| Component | What it represents |
|---|---|
| Share capital | Face value of shares issued |
| Reserves and surplus | Accumulated retained profits |
| Securities premium | Amount received above face value when shares were issued |
| Revaluation reserve | Upward revaluation of assets, where permitted |
| Less: accumulated losses | Reduces book value |
The largest component for most established companies is retained earnings — profits kept in the business rather than paid out as dividends. This is why a consistently profitable company that reinvests will see book value grow year after year, and why growing book value per share is itself a useful signal.
Why Book Value Diverges From Market Value
Book value records history. Market value prices the future. Four things drive them apart.
1. Depreciation is mechanical. A machine bought for ₹10 crore with a ten-year schedule loses ₹1 crore of book value each year, regardless of whether it has become more valuable or obsolete. The books march down a fixed staircase while the market does whatever it wants.
2. Land is never depreciated. Land stays on the books at original purchase cost forever. A company that bought land in a major city decades ago carries it at a fraction of its current value. This creates the largest book-vs-market gaps in older Indian companies.
3. Intangibles are largely invisible. A brand built over forty years, a software company’s engineering talent, a distribution network, customer relationships — these generate real earnings but appear nowhere on the balance sheet unless they were purchased. This is why asset-light businesses like IT services and consumer brands trade at high multiples of book value: their most valuable assets are not in the books at all.
4. Future earnings are not counted. Book value captures what a company owns today. The market prices what it expects the company to earn tomorrow.
The full story of how depreciation creates this gap is worth reading alongside this.
Where Book Value Is Genuinely Useful
| Sector | Is book value meaningful? | Why |
|---|---|---|
| Banks and NBFCs | Highly meaningful | Assets are loans and securities, carried close to real value |
| Insurance | Meaningful | Largely financial assets |
| Manufacturing, infrastructure | Moderately meaningful | Real physical assets, though depreciation distorts |
| IT services | Weak | Value sits in people and contracts, not on the balance sheet |
| Consumer brands | Weak | Brand value is largely unrecorded |
| Loss-making startups | Very weak | Accumulated losses can push book value negative |
This is why P/B ratio is a standard valuation tool for banks and almost useless for a software company. Comparing an IT firm’s P/B against a bank’s P/B is comparing two unrelated things.
Book Value vs Face Value vs Market Value
These three get muddled constantly.
| Face Value | Book Value | Market Value | |
|---|---|---|---|
| What it is | Nominal value assigned at issue | Accounting net worth per share | Current trading price |
| Typical figure | ₹1, ₹2, ₹5 or ₹10 | Varies by company | Whatever the market decides |
| Changes with | Only splits or consolidations | Profits, losses, dividends | Every trading tick |
| Used for | Dividend declarations, corporate actions | P/B ratio, bank valuation | Everything else |
Face value has almost no analytical use. A company declaring a “200% dividend” is declaring 200% of face value — on a ₹2 face value, that is ₹4 per share, which may be a trivial yield on a ₹800 share price. Always convert to dividend yield to see what it actually means.
What to Watch
- Growth in book value per share over time is a cleaner signal than the absolute number. Steady growth means the company is retaining and compounding profits.
- Negative book value means accumulated losses have exceeded equity. It is a serious warning sign outside of specific situations.
- A revaluation reserve that has suddenly inflated book value deserves scrutiny — it reflects an accounting decision, not cash earned.
- Compare within a sector, never across. A bank at P/B 2 and an IT company at P/B 8 tells you nothing about which is better value.
Key Takeaways
- Book Value = Total Assets − Total Liabilities, also called shareholders’ equity or net worth
- Book Value Per Share = Book Value ÷ Outstanding Shares
- Retained earnings are usually the largest component
- Book value records history; market value prices the future
- Land is never depreciated — the largest source of book-vs-market gaps
- Brands, talent and customer relationships are largely invisible in book value
- Most useful for banks and NBFCs, least useful for IT and consumer brands
- Growing book value per share is a better signal than the absolute figure
Frequently Asked Questions (FAQ)
Q: What is book value in simple terms?
Book value is what a company would be worth on paper if it sold all its assets at recorded values and paid off all its debts. It equals total assets minus total liabilities, and appears on the balance sheet as shareholders’ equity.
Q: What is the book value formula?
Book Value = Total Assets − Total Liabilities. To get book value per share, divide that figure by the number of outstanding shares. Both numbers come directly from the balance sheet.
Q: What is the difference between book value and market value?
Book value is the accounting figure based on historical cost minus depreciation. Market value is what the shares actually trade for. They differ because depreciation follows a fixed schedule, land is never depreciated, intangibles like brands are not recorded, and the market prices future earnings.
Q: Is a high book value good?
Not by itself. A high book value simply means large recorded net assets, which is common in capital-heavy industries. What matters more is whether those assets generate good returns — check ROCE alongside book value — and whether book value per share is growing over time.
Q: What does negative book value mean?
Negative book value means liabilities exceed assets, usually because accumulated losses have wiped out shareholders’ equity. It generally signals financial distress, though it can also occur in companies that have taken on large debt for buybacks.
Q: What is the difference between book value and face value?
Face value is the nominal value assigned to a share at issue, typically ₹1, ₹2 or ₹10, and rarely changes. Book value is the actual accounting net worth per share and changes as the company earns profits or losses. Face value has little analytical use.
Q: Why do IT companies have low book value but high share prices?
Because their most valuable assets — engineering talent, client relationships, brand and delivery capability — are not recorded on the balance sheet. Book value captures physical and financial assets, which asset-light businesses have few of. This is why P/B ratio is a poor valuation tool for the sector.
