What PBR is
The price to book ratio compares a company market price per share with its book value per share. It is used to understand how the market values a company relative to the net assets recorded on the balance sheet.
Formula
The original calculator uses these two formulas:
- PBR = Market Price per Share / Book Value per Share
- Book Value per Share = (Total Assets - Total Liabilities) / Outstanding Shares
This means the calculator first derives net assets from total assets minus total liabilities, then converts those net assets into a per share figure before dividing market price by that value.
Interpretation
- PBR above 1 means the market values the company above book value
- PBR below 1 means the market values the company below book value
- PBR equal to 1 means market price is aligned with book value
Interpretation depends on context. Growth expectations, intangible assets, profitability, and risk can all change how investors view the same book value.
Factors affecting PBR
Industry structure
- Asset heavy sectors often trade closer to book value
- Intangible heavy sectors can trade well above book value
Market conditions
- Strong market sentiment can lift the price side of the ratio
- Weak sentiment can compress the ratio even if balance sheet values are stable
Company quality
- Profitability and return on equity often influence valuation multiples
- Balance sheet concerns or weak earnings can lower the multiple
Typical ranges
PBR differs by industry and business model.
- Technology firms can show higher PBR values because intangible value is not fully reflected in book value
- Financial firms are often compared more directly on book value and can trade closer to 1
- Manufacturing businesses often sit somewhere in between depending on profitability and asset efficiency
