What is P/B Ratio Calculator?

The P/B (Price-to-Book) Ratio Calculator helps evaluate a stock's market value relative to its book value (net asset value). Book value represents the company's assets minus liabilities as shown on the balance sheet. A P/B ratio below 1 suggests the stock is trading below its net asset value, which could indicate an undervalued opportunity or financial distress. This metric is particularly useful for valuing banks, insurance companies, and capital-intensive businesses.

How to Use This Calculator

  1. Select calculation type (Calculate P/B, Fair Value, or Required Book Value)

Formula Used

P/B Ratio = Market Price per Share / Book Value per Share Book Value per Share = (Total Assets - Total Liabilities) / Outstanding Shares Fair Value = Book Value per Share × Target P/B Ratio Required Book Value = Market Price / Target P/B Ratio

Frequently Asked Questions

What is a good P/B ratio?

For value investors, P/B below 1 is attractive as you're buying assets at a discount. However, 'good' P/B varies by industry. Banks typically trade at 1-3x, while tech companies may have P/B of 5-15x due to intangible assets. Always compare with industry peers.

Why do some stocks have very high P/B ratios?

Asset-light businesses (software, services, pharma) have high P/B because their value comes from intellectual property, brand, and human capital, which aren't fully reflected in book value. A high P/B indicates the market values the company's earnings power over its tangible assets.

Is P/B ratio useful for all stocks?

P/B ratio is most useful for capital-intensive businesses (banks, insurance, manufacturing, real estate). It's less relevant for asset-light companies like IT services or pharma where intangible assets and intellectual property drive value.

What if a stock trades below book value (P/B < 1)?

P/B below 1 could mean: (1) Undervalued opportunity - market undervalues assets, (2) Distressed company - assets may be impaired or business struggling, or (3) Declining industry. Investigate why before assuming it's a bargain.

How is P/B different from P/E ratio?

P/E measures price relative to earnings (profitability), while P/B compares price to net assets (balance sheet). P/B provides downside protection view, while P/E shows earnings potential. Use both together for comprehensive analysis.
