What Is the Price‑to‑Book Value (P/BV) Ratio Meaning, Formula & Examples

The price-to-book value (P/BV) ratio is a valuation metric used to compare a company's market price with its book value. This ratio helps investors assess whether a stock is under or overvalued relative to its intrinsic worth. Commonly used in asset-heavy sectors, the P/BV ratio relates equity value with investor sentiment. This page explores its meaning, calculation, interpretation, and practical implications.

The P/BV ratio stands for Price-to-Book Value ratio. It measures the relationship between a company’s market price per share and its book value per share. It reflects how much investors are willing to pay for each rupee of a company’s net assets.

The “price” is the market value per share, while the “book value” is derived from a company’s balance sheet—total assets minus total liabilities. It shows the value shareholders might receive if the company were liquidated.

This ratio provides insights into how the market values a company's net worth. A P/BV ratio:

• Below 1 may imply undervaluation or underlying issues
  

• Around 1 suggests parity between book value and market price
  

• Above 1 indicates expected future growth or profitability
  

It helps assess if the market is overpricing or underpricing a stock relative to its tangible asset base.

The P/BV ratio is calculated using:

P/BV Ratio = Market Price per Share ÷ Book Value per Share

It may be calculated on a historical or projected basis, based on available data.

To calculate book value per share:

Book Value = Total Assets - Total Liabilities
Book Value per Share = Book Value ÷ Total Number of Outstanding Shares

These figures are found in a company’s financial statements.

This result is then used to derive the P/BV ratio.

A high or low P/BV must be understood in industry context:

• High P/B (>3): Indicates strong market expectations
  

• Low P/B (<1): Suggests undervaluation or potential risk
  

The P/B ratio is most useful when comparing similar companies in the same industry.

Example 1: High P/BV

Company A’s stock price is ₹500 and its book value is ₹100:

P/BV = 500 ÷ 100 = 5.0

This suggests optimism about the company’s growth.

Example 2: Low P/BV

Company B’s stock price is ₹75 and book value is ₹100:

P/BV = 75 ÷ 100 = 0.75

This may indicate undervaluation or performance concerns.

The P/BV ratio has a few limitations:

• Excludes Intangibles: Ignores brand, goodwill, or intellectual property
  

• Accounting Differences: Methods affect asset and liability values
  

• Not universal: Less effective in intangible-heavy sectors like tech
  

• Static View: Does not capture growth potential
  

It’s best used alongside ratios like P/E, ROE, or EV/EBITDA.

The ratio is effective in:

• Asset-heavy industries: Such as banking and real estate
  

• Peer comparison: Within industry averages
  

• Distress screening: Spotting potential turnaround cases
  

P/BV is a helpful valuation check when used with other tools.

The price-to-book value ratio offers an asset-focused view of a company’s valuation. It compares the market's perceived value to the firm’s tangible net worth. Though limited in scope, it adds useful context to equity evaluation.
