Book Value Per Share Calculator
Determines the net asset value attributable to each outstanding share of stock. Use it when comparing a stock's market price to its underlying balance-sheet worth.
About this calculator
Book Value Per Share (BVPS) represents the portion of a company's net assets allocated to each common share outstanding. The formula is: BVPS = Total Shareholder Equity / Outstanding Shares. Total Shareholder Equity is the difference between a company's total assets and total liabilities as reported on the balance sheet. Investors compare BVPS to the current market price to calculate the Price-to-Book (P/B) ratio — a stock trading below its BVPS may be undervalued, while one trading far above it commands a premium for intangible assets or future earnings potential. BVPS is especially meaningful for asset-heavy industries like banking, insurance, and manufacturing, where tangible assets dominate the balance sheet.
How to use
Suppose a company has total shareholder equity of $4,000,000 and 500,000 shares outstanding. Apply the formula: BVPS = $4,000,000 / 500,000 = $8.00 per share. If the stock is currently trading at $12.00, the Price-to-Book ratio is $12.00 / $8.00 = 1.5x, meaning investors are paying 50% above book value. If equity dropped to $3,000,000 due to losses, BVPS would fall to $6.00, and a $12.00 stock price would imply a P/B of 2.0x — signaling a richer valuation.
Frequently asked questions
What does it mean when a stock trades below its book value per share?
A stock trading below BVPS means the market values the company at less than its net assets on the balance sheet, which can signal undervaluation or investor skepticism about asset quality. In some cases, book value may include intangible or overvalued assets that the market discounts. Value investors often screen for stocks with low Price-to-Book ratios as potential bargains, particularly in capital-intensive sectors. However, a persistently sub-book valuation can also reflect legitimate concerns about profitability or balance-sheet risk.
How does book value per share differ from earnings per share?
BVPS is a balance-sheet metric representing accumulated net assets per share, while Earnings Per Share (EPS) is an income-statement metric showing profit generated per share over a period. BVPS reflects what shareholders would theoretically receive per share if the company were liquidated today, whereas EPS measures ongoing profitability. Investors use both together — BVPS for asset-based valuation and EPS for earnings-driven valuation — to build a comprehensive picture of a stock's worth.
Why is book value per share less meaningful for technology or service companies?
Technology and service companies derive most of their value from intangible assets such as intellectual property, brand equity, software, and human capital, which are often not fully captured on the balance sheet. BVPS is grounded in recorded tangible assets and shareholders' equity, so it can dramatically understate the true economic value of intangible-heavy businesses. This is why companies like software firms or consumer brands frequently trade at very high Price-to-Book multiples. For such firms, metrics like EV/EBITDA or Price-to-Earnings are generally more relevant valuation tools.
