Dividends paid to preferred stockholders. Enter 0 if none.
The average number of common shares outstanding over the period.
What is Earnings Per Share (EPS) and Why Does Common Stock Matter?
Earnings Per Share (EPS) is a fundamental financial metric that shows a company’s profitability on a per-share basis. The core question, “do we use common stock when calculating eps,” gets a clear answer: yes, absolutely. EPS is specifically designed to show the earnings attributable to each outstanding share of common stock. It represents the portion of a company’s profit allocated to each individual common share.
Investors and analysts heavily rely on EPS to gauge a company’s financial health and to compare its performance against other companies in the same industry. A higher EPS generally indicates greater profitability and can make a stock more attractive to investors.
The calculation intentionally excludes preferred stock from the denominator because preferred shareholders have a prior claim on earnings through fixed dividends. The formula isolates the profit that truly belongs to common stockholders.
The Basic EPS Formula and Explanation
The formula for Basic EPS is straightforward and directly answers our primary question. It explicitly uses the weighted average number of common shares as its denominator.
EPS = (Net Income – Preferred Dividends) / Weighted Average Common Shares Outstanding
This formula ensures that the earnings figure used in the numerator is the amount available exclusively to common shareholders.
Formula Variables
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Net Income | A company’s total profit after all operating expenses, interest, and taxes are deducted. | Currency (e.g., USD) | Varies widely, from negative (a loss) to billions. |
| Preferred Dividends | The total amount of dividends that a company is obligated to pay to its preferred shareholders. | Currency (e.g., USD) | Zero to millions/billions, depending on the company’s capital structure. |
| Weighted Average Common Shares | The average number of common shares held by investors over a specific period, accounting for share buybacks and issuances. | Shares (unitless number) | Thousands to billions. |
Practical Examples
Example 1: A Tech Company with No Preferred Stock
Let’s consider a growth-focused tech company that has not issued any preferred stock.
- Inputs:
- Net Income: $2,000,000
- Preferred Dividends: $0
- Weighted Average Common Shares: 5,000,000
- Calculation: ($2,000,000 – $0) / 5,000,000 shares
- Result: Basic EPS = $0.40
Example 2: An Established Utility Company
Now, let’s look at a stable utility company that uses preferred stock as part of its capital structure.
- Inputs:
- Net Income: $500,000,000
- Preferred Dividends: $50,000,000
- Weighted Average Common Shares: 200,000,000
- Calculation: ($500,000,000 – $50,000,000) / 200,000,000 shares
- Result: Basic EPS = $2.25
How to Use This EPS Calculator
Using this calculator is simple and helps illustrate how common stock is used in the EPS calculation.
- Enter Net Income: Input the company’s net income for the period (e.g., quarterly or annually). You can find this on the income statement.
- Enter Preferred Dividends: Input the total dividends paid to preferred shareholders. If the company has no preferred stock, enter ‘0’.
- Enter Common Shares: Input the weighted average number of common shares outstanding for the period. This figure accounts for changes in the number of shares over time.
- Calculate and Interpret: Click “Calculate EPS”. The result shows the profit generated for each share of common stock. The intermediate values show how the earnings available to common shareholders are derived.
Key Factors That Affect Earnings Per Share
Several factors can influence a company’s EPS, highlighting the importance of understanding its components.
- Net Income Growth: The most direct driver. Higher profits lead to a higher EPS, assuming the share count remains stable.
- Share Buybacks: When a company buys back its own common stock, it reduces the number of outstanding shares. This decrease in the denominator increases EPS.
- New Share Issuances: Conversely, when a company issues new common stock, it increases the number of outstanding shares, which dilutes or decreases EPS.
- Profit Margins: Improved operational efficiency that boosts profit margins will increase net income and, consequently, EPS.
- Changes in Preferred Dividends: An increase in preferred dividend obligations reduces the earnings available to common stockholders, thereby lowering EPS.
- Corporate Strategy: Management decisions, such as pursuing growth over immediate profitability, can temporarily lower EPS but may lead to higher future earnings.
Frequently Asked Questions (FAQ)
- 1. Why are preferred dividends subtracted in the EPS formula?
- Preferred dividends are subtracted because they represent a claim on earnings senior to that of common stockholders. The EPS calculation is meant to show the profit available specifically to common shareholders.
- 2. What is the difference between basic and diluted EPS?
- Basic EPS uses the weighted average of common shares currently outstanding. Diluted EPS is a more conservative measure that includes the impact of all potential common shares from convertible securities (like stock options and convertible bonds), which would increase the share count.
- 3. Is a higher EPS always better?
- Generally, yes. A higher EPS indicates better profitability. However, it should not be viewed in isolation. It’s important to consider the industry, the company’s growth stage, and whether the EPS growth is sustainable or due to one-time events or share buybacks.
- 4. How is the ‘weighted average’ number of common shares calculated?
- It’s calculated by taking the number of shares outstanding during a period and weighting them by the portion of the period they were outstanding. This provides a more accurate picture than simply using the number of shares at the end of the period.
- 5. Does a stock split affect EPS?
- Yes. A stock split increases the number of common shares outstanding. Companies must retroactively adjust their historical EPS data to reflect the split, ensuring comparability over time.
- 6. Why not use preferred stock in the denominator?
- Preferred stock is more like a debt instrument, often with a fixed dividend payment and no voting rights. EPS is a measure of profitability for the owners with voting rights and residual claim on assets—the common stockholders.
- 7. What if a company has a net loss?
- If a company has a net loss, it will report a negative EPS, often referred to as a “net loss per share.” The calculation remains the same: (Net Loss – Preferred Dividends) / Weighted Average Common Shares.
- 8. Where can I find the numbers for the EPS calculation?
- All the necessary information (Net Income, Preferred Dividends, and Weighted Average Shares) is typically found in a public company’s quarterly (10-Q) and annual (10-K) financial reports, specifically on the Income Statement and in its footnotes.
