Earnings Per Share Calculator
Calculate basic and diluted EPS from net income, preferred dividends, and shares outstanding. Enter values for instant results with step-by-step formulas.
Formula
Basic EPS = (Net Income - Preferred Dividends) / Weighted Average Common Shares Outstanding
Basic EPS divides earnings available to common shareholders by the weighted average common shares outstanding. Diluted EPS uses the same numerator but includes all potentially dilutive securities in the denominator. P/E Ratio = Stock Price / EPS. PEG Ratio = P/E / EPS Growth Rate.
Worked Examples
Example 1: Basic and Diluted EPS Calculation for a Growth Company
Problem: A technology company reports net income of $50 million, preferred dividends of $2 million, 10 million basic shares, and 12 million diluted shares (including 2 million from stock options). Stock trades at $80.
Solution: Earnings Available = $50,000,000 - $2,000,000 = $48,000,000\nBasic EPS = $48,000,000 / 10,000,000 = $4.80\nDiluted EPS = $48,000,000 / 12,000,000 = $4.00\nDilution Impact = ($4.80 - $4.00) / $4.80 = 16.7% reduction\nP/E Ratio (Basic) = $80 / $4.80 = 16.67x\nP/E Ratio (Diluted) = $80 / $4.00 = 20.00x\nEarnings Yield = $4.80 / $80 = 6.0%
Result: Basic EPS: $4.80 | Diluted EPS: $4.00 | P/E: 16.67x (Basic), 20.0x (Diluted) | 16.7% Dilution
Example 2: EPS Growth Analysis and PEG Ratio Valuation
Problem: A company had EPS of $3.50 last year and reports current EPS of $4.20. The stock trades at $84. Revenue is $500 million with $60 million net income. Calculate growth rate and PEG ratio.
Solution: EPS Growth = ($4.20 - $3.50) / $3.50 = 20.0%\nP/E Ratio = $84 / $4.20 = 20.0x\nPEG Ratio = 20.0 / 20.0 = 1.00\nEarnings Yield = $4.20 / $84 = 5.0%\nProfit Margin = $60M / $500M = 12.0%\nMarket Cap = $84 x shares outstanding\nForward P/E (at same growth) = $84 / ($4.20 x 1.20) = $84 / $5.04 = 16.67x
Result: EPS Growth: 20.0% | P/E: 20.0x | PEG: 1.00 (Fair Value) | Forward P/E: 16.67x
Frequently Asked Questions
What is earnings per share and why is it the most important profitability metric?
Earnings per share (EPS) measures the portion of a company net income allocated to each outstanding share of common stock, calculated by dividing net income minus preferred dividends by the weighted average number of common shares outstanding. EPS is considered the most important profitability metric because it normalizes earnings across companies of different sizes, enabling direct comparison. A company earning $10 billion with 5 billion shares ($2.00 EPS) is directly comparable to one earning $500 million with 100 million shares ($5.00 EPS). EPS is the denominator in the price-to-earnings ratio, making it the foundation of equity valuation. Wall Street analysts track EPS estimates obsessively, and even small deviations from consensus estimates can cause significant stock price movements.
What is the significance of EPS beats and misses during earnings season?
When a company reports quarterly EPS above analyst consensus estimates (a beat) or below (a miss), it can trigger significant stock price movements because EPS surprises force analysts to update their valuation models and price targets. Historical data shows that stocks beating EPS estimates by more than 5% outperform the market by an average of 2-3% in the following month, while misses of similar magnitude underperform by a comparable amount. However, the magnitude of the price reaction depends heavily on the quality of the beat or miss. Revenue-driven EPS beats (higher sales) are valued more than cost-cutting beats. Forward guidance often matters more than the actual EPS number, with companies guiding above consensus seeing larger positive reactions than the EPS beat alone would warrant. Institutional investors track earnings revision momentum as a systematic factor.
