Earnings Per Share Calculator - Basic and Diluted EPS

Earnings per share, or EPS, expresses the portion of a company's profit attributable to each common share. This Earnings Per Share Calculator starts with net income, subtracts dividends owed to preferred shareholders, and divides the amount remaining by common shares outstanding. EPS is a foundational measure in company reporting and equity analysis because it connects overall profitability with the ownership claim represented by one share. It is most helpful when evaluated over time and alongside revenue growth, margins, cash flow, share-count changes, and the quality of reported earnings. Basic EPS uses earnings available to common shareholders divided by shares outstanding. If net income is $1,000,000, preferred dividends are $50,000, and one million common shares are outstanding, basic EPS is $0.95. Diluted EPS uses a larger share count when convertible securities, options, warrants, or other instruments could become common shares. A larger denominator lowers EPS unless those instruments are anti-dilutive under applicable accounting rules. The calculator accepts an estimated number of dilutive securities for a simple comparison, while formal financial statements use weighted-average shares and detailed rules for each instrument. An optional market price produces a price-to-earnings ratio by dividing price per share by basic EPS. P/E is a valuation shorthand, not a conclusion about whether a share is cheap or expensive. A high P/E can reflect expectations for faster future growth, lower risk, temporary earnings pressure, or overvaluation. A low P/E can signal value, cyclical peak earnings, weak prospects, or accounting differences. Compare EPS and P/E with peers that have similar business models, capital structures, growth rates, and accounting policies. Use reported figures from the same period and distinguish basic shares from weighted-average shares. Stock splits, repurchases, share issuances, acquisitions, one-time gains, discontinued operations, and preferred-conversion terms can all affect a meaningful EPS comparison. Negative net income requires special presentation and can make P/E not meaningful; this simple calculator is intended for non-negative scenarios. It does not replace GAAP or IFRS disclosures, audited financial statements, valuation analysis, or investment advice. Review company filings to understand how management calculated diluted shares and whether earnings are supported by sustainable operations and cash flow.
