You find earnings per share by subtracting preferred dividends from a company’s net income and dividing that result by the weighted average number of common shares outstanding.
Investors look at this number to judge profitability. It tells you exactly how much profit belongs to each individual share of stock you own. You do not need a degree in finance to work this out. The formula is straightforward, and the data sits publicly on company financial statements.
Many beginners rely on financial news sites to see this number. However, knowing how to calculate it yourself gives you a sharper edge. You can spot trends, adjust for one-time events, and understand the true quality of a company’s earnings.
The Core Formula Behind EPS
The math requires three specific numbers from a company’s financial reports. You must locate the Net Income, the Preferred Dividends (if any), and the Weighted Average Shares Outstanding.
The standard formula looks like this:
EPS = (Net Income – Preferred Dividends) / Weighted Average Shares Outstanding
Net income represents the total profit after all expenses and taxes. Preferred dividends are payments made to preferred shareholders before common shareholders get anything. The weighted average shares account for any stock buybacks or new issuances during the year.
You might see variations of this, such as Diluted EPS. Basic EPS uses the shares currently on the market. Diluted EPS assumes that all stock options and convertible bonds turn into stock, which increases the share count and lowers the earnings per share.
How To Calculate Earnings Per Share Accurately
You can perform this calculation manually using the company’s income statement. Follow this logical process to get the correct figure.
- Locate Net Income — Find this line item at the bottom of the company’s Income Statement; it shows total profit for the period.
- Subtract Preferred Dividends — Check the equity section or footnotes to see if the company paid dividends to preferred stockholders and deduct this amount.
- Find Share Count — Look for the “Weighted Average Shares Outstanding” line on the income statement, usually just below net income.
- Divide The Result — Take your adjusted net income (profit minus dividends) and divide it by the share count to get the EPS value.
Quick check: If a company has no preferred stock, the math is simply Net Income divided by Shares Outstanding. Many tech companies fall into this category, making the math easier.
Where To Locate The Financial Data
You need accurate source documents to perform this analysis. Public companies must file these reports with the SEC in the United States. They are free to access.
The 10-K And 10-Q Reports
The most reliable source is the company’s annual report (Form 10-K) or quarterly report (Form 10-Q). You can find these on the SEC EDGAR database or the “Investor Relations” page of the company’s website.
Open the report and scroll to the “Consolidated Statements of Operations” or “Income Statement.” This single page usually contains every number you need. Companies are legally required to list both Basic and Diluted EPS at the bottom of this statement.
Financial News Portals
Sites like Yahoo Finance, Google Finance, or Morningstar provide these numbers instantly. They pull data directly from the filings. While convenient, these portals sometimes average out numbers or use “Adjusted EPS,” which might exclude certain expenses. Always verify with the official filing if you are making a large investment decision.
Basic vs. Diluted EPS Explained
You will often see two different EPS numbers listed side by side. Understanding the difference prevents you from overestimating a stock’s value.
Basic EPS ignores the potential for new shares to enter the market. It only counts the shares that currently exist. This number is often higher.
Diluted EPS is the more conservative number. It asks, “What if every employee exercised their stock options and every convertible bond turned into stock?” This scenario increases the denominator in your fraction, which lowers the final EPS. Professional investors almost always use Diluted EPS because it represents the “worst-case” share count.
Real-World Calculation Example
Let’s look at a hypothetical scenario for “TechCorp Inc.” to see the math in action.
TechCorp reported a Net Income of $10 million. They paid $1 million in dividends to preferred shareholders. During the year, they had a weighted average of 4.5 million shares outstanding.
Step 1: Adjust The Income
$10,000,000 (Net Income) – $1,000,000 (Preferred Dividends) = $9,000,000.
Step 2: Divide By Shares
$9,000,000 / 4,500,000 shares = $2.00 per share.
This means for every share of TechCorp you own, the company generated $2.00 of profit. If the stock trades at $20.00, the Price-to-Earnings (P/E) ratio is 10.
Why This Metric Matters For Valuation
Earnings per share drives the stock price more than almost any other metric. It connects the company’s total profit to your specific stake in the business.
The Link To P/E Ratio
The Price-to-Earnings ratio is the most common valuation tool. To find it, you divide the current stock price by the EPS. If you do not have the EPS, you cannot calculate the P/E ratio. A rising EPS often leads to a rising stock price, assuming the valuation multiple stays the same.
Tracking Growth Over Time
Investors care about the direction of the EPS. Is it growing year over year? A company that grows its EPS from $2.00 to $2.50 shows a 25% increase in profitability. This growth often fuels stock rallies. If EPS stays flat while revenue grows, it might indicate the company is issuing too many new shares, diluting your value.
Common Traps In EPS Analysis
Reviewing this number requires context. Companies can manipulate EPS without actually making more operational profit. You should watch for these specific red flags.
Share Buybacks
A company can buy its own shares from the open market to reduce the share count. If Net Income stays flat but the share count drops, EPS goes up. This creates the illusion of growth. Always check if EPS growth comes from higher income or fewer shares.
One-Time Gains
Sometimes a company sells a factory or a subsidiary. This generates a massive, one-time spike in Net Income. This inflates the EPS for that single quarter. This profit is not repeatable. You should strip out these one-time events to see the “Core EPS” or “Adjusted EPS.”
Comparing EPS Across Industries
You cannot compare the EPS of a bank to the EPS of a tech startup. The capital structures differ wildly. A bank might have billions of shares, resulting in a low EPS but a stable dividend. A tech firm might have fewer shares and high growth.
Use EPS to compare Company A against Company B only if they operate in the same sector. For example, comparing Ford to GM makes sense. Comparing Ford to Apple does not.
| Metric | Company A (Retail) | Company B (Retail) |
|---|---|---|
| Net Income | $5,000,000 | $8,000,000 |
| Shares Outstanding | 2,000,000 | 5,000,000 |
| EPS | $2.50 | $1.60 |
In the table above, Company B makes more total money. However, Company A is more efficient on a per-share basis. As a shareholder, your slice of the profit is larger with Company A.
Forward EPS vs. Trailing EPS
The calculation we discussed uses past data. This is called Trailing Twelve Month (TTM) EPS. The stock market is a forward-looking machine, so you will also hear about Forward EPS.
Trailing EPS relies on actual, reported facts. It is 100% accurate but looks backward. It tells you what already happened.
Forward EPS relies on analyst estimates for the next year. It is useful for predicting future stock prices but is essentially an educated guess. Analysts often get it wrong. When you calculate P/E ratios, clarify whether you are using the past earnings (Trailing P/E) or the estimated future earnings (Forward P/E).
Interpreting Negative EPS
A negative EPS means the company lost money. You will see this often with young biotech firms or high-growth tech startups that spend heavily on marketing.
A negative number does not always mean a bad investment. Amazon had negative earnings for years while it built its infrastructure. However, established companies with negative EPS pose a risk. It implies their expenses exceed their revenue.
When you see a negative sign (e.g., -$0.50), the P/E ratio becomes undefined. In these cases, investors switch to other metrics like Price-to-Sales (P/S) to value the business.
Steps To Automate Your EPS Tracking
You do not need to calculate this manually every quarter. You can set up tools to track it for you.
- Use Stock Screeners — Filters on sites like Finviz allow you to search for companies with EPS growth above 20%.
- Read Analyst Reports — Brokerages often provide detailed PDF reports that break down the quality of the EPS.
- Check Investor Presentations — Companies publish slide decks during earnings calls. They often explicitly bridge the gap between their GAAP EPS and their Adjusted EPS.

Frequently Asked Questions
Is a higher EPS always better for investors?
Generally, yes, but context is necessary. A higher EPS indicates more profit per share. However, if the stock price is extremely high, a high EPS might still result in a low yield. Always compare EPS to the share price (P/E ratio) and check if the growth is sustainable.
Can EPS be different on different websites?
Yes. Some sites display “Adjusted EPS,” which ignores one-time costs like restructuring charges. Others show “GAAP EPS,” which follows strict accounting rules. Always check the label to know which version you are viewing, as the difference can be significant.
What is the weighted average shares outstanding?
This number accounts for changes in share count during the year. If a company issues new shares in June, using the December share count would be inaccurate. The weighted average calculates the mean number of shares that existed throughout the entire reporting period.
How often is EPS updated?
Public companies update their EPS figures quarterly (every three months) when they release their 10-Q reports. A full-year EPS is finalized in the annual 10-K report. Analysts may update their Forward EPS estimates more frequently based on news or economic shifts.
Does Warren Buffett look at earnings per share?
Buffett looks at “Owner Earnings,” which is similar but focuses more on cash flow than accounting profit. While he considers EPS, he pays closer attention to how much cash the business generates for its owners after necessary capital expenditures.
Wrapping It Up – How Do You Find Earnings Per Share?
You calculate earnings per share to understand the true profitability of your investment. It cuts through the noise of total revenue and tells you exactly what your specific shares earned. By mastering this simple formula, you can separate growing companies from stagnant ones.
Remember to check the Diluted EPS for a safer view and verify the numbers in the official SEC filings. Do not rely solely on summary pages. With this knowledge, you are better equipped to value stocks and build a stronger portfolio.
