How to Calculate Earnings Per Share (EPS): A Step-by-Step Guide

Chris Carreck, August 21, 2024August 18, 2024

Earnings Per Share (EPS) is a critical metric that investors use to gauge a company’s profitability. It tells you how much money a company makes for each share of its stock. Understanding EPS is vital because it helps you compare the profitability of different companies, even if they have different numbers of shares outstanding.

In this article, we’ll dive into how to calculate EPS, what it means, and why it matters for investors. We’ll also touch on how stock prices relate to EPS and why you should pay attention to this metric when evaluating potential investments.

What Is Earnings Per Share (EPS)?

Earnings Per Share (EPS) is a financial ratio that measures the portion of a company’s profit allocated to each outstanding share of common stock. It’s a widely used indicator of a company’s profitability on a per-share basis, making it easier for investors to compare companies of different sizes within the same industry.

The basic formula for calculating Earnings Per Share (EPS) is:

EPS=Net Income−Preferred DividendsWeighted Average Shares Outstanding\text{EPS} = \frac{\text{Net Income} – \text{Preferred Dividends}}{\text{Weighted Average Shares Outstanding}}EPS=Weighted Average Shares OutstandingNet Income−Preferred Dividends​

Where:

  • Net Income: The total profit of a company after taxes and all expenses.
  • Preferred Dividends: Dividends that are required to be paid to preferred shareholders before any earnings can be allocated to common shareholders.
  • Weighted Average Shares Outstanding: The average number of shares a company has outstanding over a reporting period, adjusted for any stock splits or stock dividends.

There are different types of EPS calculations, including Basic EPS and Diluted EPS. Basic EPS is simpler and doesn’t take into account the potential dilution from convertible securities like options or warrants, while Diluted EPS does.

Why EPS Matters

EPS is an important indicator of a company’s profitability and a key metric used by investors to determine the financial health of a company. A higher EPS indicates better profitability, meaning the company is earning more profit per share of stock.

EPS is also used in several other important financial metrics, such as the Price-to-Earnings (P/E) ratio, which compares a company’s stock price to its EPS:

P/E Ratio=Stock PriceEPS\text{P/E Ratio} = \frac{\text{Stock Price}}{\text{EPS}}P/E Ratio=EPSStock Price​

A lower P/E ratio might indicate that a stock is undervalued, whereas a higher P/E ratio could mean that a stock is overvalued relative to its earnings.

How to Calculate EPS: An Example

Let’s walk through a simplified example to see how EPS is calculated.

Suppose we have the following information about a company:

  • Net Income: $500 million
  • Preferred Dividends: $50 million
  • Weighted Average Shares Outstanding: 200 million shares

Using the EPS formula:

EPS=Net Income−Preferred DividendsWeighted Average Shares Outstanding\text{EPS} = \frac{\text{Net Income} – \text{Preferred Dividends}}{\text{Weighted Average Shares Outstanding}}EPS=Weighted Average Shares OutstandingNet Income−Preferred Dividends​ EPS=500,000,000−50,000,000200,000,000=450,000,000200,000,000=2.25\text{EPS} = \frac{500,000,000 – 50,000,000}{200,000,000} = \frac{450,000,000}{200,000,000} = 2.25EPS=200,000,000500,000,000−50,000,000​=200,000,000450,000,000​=2.25

In this example, the company’s EPS would be $2.25. This means that for every share of stock, the company earned $2.25 over the reporting period.

The Relationship Between Stock Price and EPS

While EPS is a crucial measure of a company’s profitability, it’s important to understand how it relates to the stock price. In the stock market, the price of a stock is often influenced by the company’s EPS, among other factors like market sentiment, economic conditions, and industry trends.

For example, if a company’s stock price is $165 and its EPS is $1.89, as in the scenario you mentioned, it implies a Price-to-Earnings (P/E) ratio of:

P/E Ratio=1651.89≈87.3\text{P/E Ratio} = \frac{165}{1.89} \approx 87.3P/E Ratio=1.89165​≈87.3

A P/E ratio of 87.3 means that investors are willing to pay $87.3 for every $1 of earnings. This could indicate that the stock is overvalued, especially if the industry average P/E ratio is significantly lower. However, a high P/E ratio can also be justified if the company is expected to have high growth in the future.

Interpreting EPS in Investment Decisions

When considering EPS as part of your investment strategy, it’s crucial to look at it in context:

  1. Historical EPS Trends: Is the company’s EPS growing, shrinking, or remaining stable? A consistently growing EPS suggests that the company is increasing its profitability, which is a positive sign for investors.
  2. Comparative EPS: How does the company’s EPS compare to its competitors? This can provide insight into how well the company is performing within its industry.
  3. EPS Guidance: Companies often provide guidance on expected future EPS. This can help investors gauge future profitability and make more informed decisions.
  4. P/E Ratio Analysis: Use the P/E ratio in conjunction with EPS to determine if the stock is fairly valued, overvalued, or undervalued.

Common Pitfalls When Using EPS

While EPS is a valuable metric, it’s important to be aware of its limitations:

  • EPS Can Be Manipulated: Companies can sometimes manipulate EPS through accounting practices. For example, they might buy back shares to reduce the number of shares outstanding, thereby increasing EPS without actually improving profitability.
  • Non-Recurring Items: EPS can be affected by non-recurring items like asset sales, litigation expenses, or restructuring costs. It’s important to look at adjusted EPS, which excludes these items, to get a clearer picture of the company’s true earnings potential.
  • Focus on Diluted EPS: Always consider diluted EPS, especially if the company has a lot of convertible securities that could dilute the earnings per share if exercised.

Why the Earnings Per Share (EPS) is Important

Earnings Per Share (EPS) is a fundamental metric that every investor should understand. It provides a snapshot of a company’s profitability on a per-share basis and is a key component of the P/E ratio, which helps investors assess the value of a stock.

In the example provided, a stock price of $165 with an EPS of $1.89 gives a P/E ratio of about 87.3, indicating how much investors are willing to pay for each dollar of earnings. This high P/E ratio could suggest that the market expects significant future growth from the company.

However, as with any financial metric, EPS should not be used in isolation. It’s essential to consider the broader financial picture, including revenue growth, cash flow, debt levels, and industry conditions. By doing so, you can make more informed investment decisions that align with your long-term financial goals.

Always remember, do your own research, understand the fundamentals of the companies you invest in, and don’t rely solely on stock tips or trends. Understanding metrics like EPS is just one part of building a successful investment strategy.

Happy Investing!
