Price to Book (P/B) Ratio Calculator
Compare a corporation’s market capitalization against the net accounting value of its balance sheet assets. The Price-to-Book (P/B) multiple is a cornerstone metric for value investors evaluating commercial banks, insurance firms, and capital-intensive companies.
Current market trading price per share
Net stockholders’ equity divided by outstanding common shares
Market price divided by accounting book value per share
How to Use This Calculator
- Enter the current stock market quote per share.
- Enter the company’s Book Value Per Share (BVPS) from its latest quarterly balance sheet.
- Review the calculated P/B multiple and market premium/discount percentage.
- Compare the multiple against historical sector averages (particularly financial and industrial peers).
Formula & Calculation Methodology
Book value per share equals total corporate assets minus liabilities and intangible assets, divided by common shares outstanding. A P/B ratio under 1.0 indicates a stock trading below its reported net asset value.
Worked Example

Frequently Asked Questions
What does a Price-to-Book ratio below 1.0 indicate?↓
A P/B ratio under 1.0 means the stock is trading for less than the liquidation value of its balance sheet assets. This may indicate an undervalued opportunity or market skepticism regarding bad loans and asset write-downs.
Why is the P/B ratio less useful for modern software and tech companies?↓
Tech and service firms generate enterprise value through intangible assets (codebases, brand equity, patents, and customer networks) which GAAP accounting does not fully reflect on corporate balance sheets.
Which sectors are best suited for P/B valuation?↓
Capital-intensive sectors such as commercial banking, insurance, real estate holding firms, and utilities are the primary sectors benchmarked against book value.
What is Tangible Book Value?↓
Tangible book value strips goodwill and acquired intangible assets out of the balance sheet, reflecting only physical and financial assets that could be liquidated in a formal wind-down.
