Price-to-Book Ratio Calculator
Calculate price-to-book value ratio
About this calculator
The Price-to-Book Ratio Calculator helps investors evaluate whether a stock is undervalued or overvalued by comparing its market price to its book value per share. This fundamental analysis tool calculates the P/B ratio, which indicates how much investors are willing to pay for each dollar of net assets. A lower P/B ratio may suggest an undervalued stock, while a higher ratio could indicate overvaluation or growth expectations.
How to use
Enter the current stock price per share and the book value per share (found in company financial statements). The calculator will automatically compute the P/B ratio by dividing the market price by the book value. Compare the result with industry averages and historical ratios to assess investment attractiveness.
Frequently asked questions
What is a good P/B ratio?
Generally, a P/B ratio below 1.0 suggests potential undervaluation, while ratios above 3.0 may indicate overvaluation, though this varies by industry and market conditions.
Where do I find book value per share?
Book value per share is calculated from company balance sheets or found in financial databases, annual reports, and investment research platforms.
Is P/B ratio reliable for all stocks?
P/B ratio works best for asset-heavy companies but may be less meaningful for service companies or high-growth tech stocks with few tangible assets.
