Key Takeaways
- Equity is the value remaining after all liabilities are subtracted from total assets
- Shareholders' equity represents the net worth of a company belonging to its owners
- Equity can refer to stock ownership, home equity, or private equity investing
- Return on equity (ROE) measures how effectively a company uses equity to generate profit
Definition
Equity represents ownership value. In its broadest sense, equity is the amount of money that would be returned to an entity's owners if all assets were liquidated and all debts paid off. It is calculated using the formula: Equity = Total Assets - Total Liabilities.
In the context of publicly traded companies, shareholders' equity (also called stockholders' equity or book value) appears on the balance sheet and represents the net worth attributable to shareholders. It includes paid-in capital (money invested by shareholders), retained earnings (accumulated profits not distributed as dividends), and other comprehensive income.
The term equity is also used in other financial contexts. Home equity is the difference between a home's market value and the outstanding mortgage balance. Private equity refers to investment funds that buy and restructure companies. Brand equity refers to the value a recognizable brand adds to a product.
How It Works
Shareholders' equity on a company's balance sheet is calculated as: Shareholders' Equity = Total Assets - Total Liabilities. It can also be expressed as: Shareholders' Equity = Paid-in Capital + Retained Earnings + Accumulated Other Comprehensive Income - Treasury Stock.
Equity changes over time as a company earns profits or incurs losses, issues or repurchases shares, and pays dividends. When a company earns a profit, retained earnings increase, boosting equity. When it pays dividends, retained earnings decrease. Share buybacks reduce equity through an increase in treasury stock, while new share issuances increase paid-in capital.
Investors use return on equity (ROE) to evaluate how efficiently management uses shareholders' equity: ROE = Net Income / Shareholders' Equity. A higher ROE indicates more efficient use of equity capital. The price-to-book ratio compares a stock's market price to its book value per share, indicating whether the market values the company above or below its accounting equity.
Example
Consider Johnson & Johnson (JNJ) with total assets of $187 billion and total liabilities of $111 billion. Its shareholders' equity is $187B - $111B = $76 billion. If JNJ earned $17.9 billion in net income for the year, its ROE would be $17.9B / $76B = 23.6%, meaning it generated 23.6 cents of profit for every dollar of shareholders' equity. With approximately 2.41 billion shares outstanding, book value per share is $76B / 2.41B = $31.54. If the stock trades at $155, the price-to-book ratio is $155 / $31.54 = 4.91x.
Why It Matters
Equity is one of the most fundamental concepts in finance because it represents true ownership value. For investors, shareholders' equity on the balance sheet provides a baseline measure of what a company is worth from an accounting perspective. Comparing market capitalization to book value helps determine whether a stock is trading at a premium or discount to its net assets.
Growing equity over time is generally a positive sign that a company is creating value for shareholders. Companies with strong, consistent equity growth tend to be financially healthy and well-managed. Conversely, declining equity can signal financial distress, excessive debt, or operating losses.
