How to calculate EPS (earnings per share)

Key takeaways

Earnings per share (EPS) is one of the most widely used financial metrics in investing. It helps investors understand how profitable a company is on a per-share basis and plays a key role in stock valuation and earnings analysis.

  • EPS shows how much profit a company earns per share of common stock, making it easier to compare performance across companies.

  • The EPS calculation depends on accurate net income and weighted average shares outstanding, not just total shares at year-end.

  • EPS should generally be used alongside other metrics, such as cash flow and revenue growth, for a complete picture of financial health.

What is EPS (earnings per share)?

Earnings per share (EPS) measures how much profit a company generates per outstanding share of common stock. It represents the portion of a company’s earnings allocated to each share owned by investors.

What EPS tells investors

EPS helps investors understand:

  • Profitability on a per-share basis

  • How a company’s performance changes over time

  • How one company compares to others in the same industry

Because EPS standardizes earnings across share counts, it’s often especially useful for comparisons.

Where EPS is found

EPS is commonly reported on:

  • Income statements

  • Quarterly and annual earnings reports

  • Financial news websites and stock screeners

Most public companies report both basic and diluted EPS.

The EPS formula explained

Basic EPS formula

The standard EPS formula is:

EPS = (Net income − preferred dividends) ÷ weighted average shares outstanding

Why preferred dividends are subtracted

EPS measures earnings available to common shareholders. Since preferred shareholders have priority claims on dividends, their dividends are subtracted before calculating earnings attributable to common stock.

Why weighted average shares are used

Companies rarely have the same number of shares outstanding all year. The weighted average accounts for changes caused by:

  • Stock issuance

  • Share buybacks

  • Stock splits

Using a weighted average can prevent EPS from being distorted by timing differences.

 

Step-by-step: How to calculate EPS

Step 1: Find net income

Locate net income on the income statement. This figure generally appears at the bottom and reflects earnings after taxes and expenses.

Step 2: Subtract preferred dividends (if any)

If the company has preferred stock, subtract preferred dividends. Many companies do not issue preferred stock, in which case this step equals zero.

Step 3: Determine weighted average shares outstanding

Use the weighted average number of shares outstanding over the reporting period, not just the ending share count.

Step 4: Divide to get EPS

Divide earnings available to common shareholders by the weighted average shares to calculate EPS.

 

EPS calculation example

Simple EPS example

Let’s use the following company information as an example:

  • Net income: $10 million

  • Preferred dividends: $1 million

  • Weighted average shares outstanding: 5 million

Calculation:

($10 million − $1 million) ÷ 5 million = $1.80 EPS

What the result means

An EPS of $1.80 means the company earned $1.80 in profit for each outstanding share of common stock during the period.

 

Basic EPS vs. diluted EPS

What is basic EPS?

Basic EPS uses only the shares of common stock currently outstanding.

What is diluted EPS?

Diluted EPS includes the impact of potential additional shares issued in the form of:

  • Stock options

  • Warrants

  • Convertible bonds or preferred stock

Why diluted EPS matters

Diluted EPS reflects the potential impact on earnings per share if all convertible securities were exercised.

 

Where to find EPS on financial statements

Income statement presentation

Public companies typically report:

  • Basic EPS

  • Diluted EPS

These figures usually appear near the bottom of the income statement.

Quarterly vs. annual EPS

EPS can be reported as:

  • Quarterly EPS: performance for a single quarter

  • Trailing twelve months (TTM) EPS: combined results from the last four quarters

TTM EPS is often used for valuation ratios.

 

Why EPS is important to investors

Company profitability

Consistent EPS growth can reflect improving profitability, though it should be evaluated alongside other financial indicators.

Stock valuation

EPS is commonly used in valuation metrics such as the price-to-earnings (P/E) ratio, which compares stock price to earnings.

Earnings comparisons

EPS allows investors to compare companies of different sizes and track performance over time.

 

Limitations of EPS

EPS can be manipulated

EPS can increase without real business improvement through:

  • Share buybacks that reduce share count

  • Accounting changes that affect reported earnings

EPS doesn’t show cash flow

EPS is based on accounting profit, not actual cash generated by the business.

Industry comparisons can be misleading

Capital-intensive industries often have different EPS profiles than asset-light businesses, making cross-industry comparisons less meaningful.

 

EPS vs. other profitability metrics

EPS vs. net income

Net income shows total profit while EPS shows profit per share.

EPS vs. free cash flow per share

Free cash flow per share focuses on actual cash generation rather than accounting earnings.

EPS vs. EBITDA

EPS is more shareholder focused. Earnings before interest, taxes, depreciation, and amortization (EBITDA) focuses more on a company’s profitability from its daily operations.

Common mistakes when calculating or using EPS

Forgetting preferred dividends

This may overstate earnings available to common shareholders.

Using the wrong share count

Using end-of-period shares instead of weighted average shares may distort EPS.

Relying on EPS alone

EPS should not replace broader financial analysis.

Bottom line

EPS is a foundational metric for evaluating company profitability and stock valuation, but it often works best when used in context. Understanding how EPS is calculated along with its limitations helps investors make more informed decisions.

It’s also important to keep in mind that investments can go down as well as up in value. Past performance and earnings growth do not guarantee future results.

Frequently asked questions

Divide earnings available to common shareholders by the weighted average number of shares outstanding.

There’s no universal “good” EPS — it depends on the company, industry, and growth trends.

A higher EPS may indicate stronger profitability, but context matters. Investors often consider growth trends, industry conditions, and overall financial health.

Reporting both can show current earnings per share and potential dilution risk for shareholders.
