Calculate basic and diluted Earnings Per Share from net income, preferred dividends, and share count. Essential for stock valuation and P/E analysis.
Earnings Per Share (EPS) is the portion of a company's net profit allocated to each outstanding share of common stock. It is the foundational building block of stock valuation — the denominator in the P/E ratio and a key input for dozens of other financial metrics.
Our EPS Calculator computes both basic EPS (using only outstanding shares) and diluted EPS (which includes the impact of stock options, convertible bonds, and other potentially dilutive securities). Enter net income, preferred dividends, basic shares outstanding, and dilutive shares to get both figures instantly.
Understanding EPS helps you evaluate profitability on a per-share basis, compare companies of different sizes, and track whether a company is growing its earnings over time. Diluted EPS is particularly important because it accounts for stock options, convertible debt, and warrants that could increase the share count and reduce each investor's claim on earnings. Tracking EPS trends over time reveals whether growth is genuine or driven by financial engineering.
A company earning $1 billion sounds impressive, but if it has 10 billion shares outstanding, EPS is only $0.10. Another company earning $100 million with 50 million shares has an EPS of $2.00 — far more valuable per share. EPS normalizes profitability and is essential for meaningful valuation comparisons. Without it, comparing a large conglomerate to a smaller competitor is effectively meaningless.
Basic EPS = (Net Income − Preferred Dividends) / Weighted Average Shares Outstanding. Diluted EPS = (Net Income − Preferred Dividends) / (Basic Shares + Dilutive Shares).
Result: Basic EPS: $4.90, Diluted EPS: $4.67
With $2.5 billion in net income, $50 million in preferred dividends, and 500 million basic shares, the basic EPS is $4.90. Adding 25 million dilutive shares from options and convertibles reduces EPS to $4.67 diluted — a 4.7% dilution impact.
Nearly every valuation metric builds on EPS. The P/E ratio divides price by EPS. The PEG ratio divides P/E by EPS growth. Dividend payout ratio divides dividends by EPS. Mastering EPS means understanding the building block of stock analysis.
Stock-based compensation is common in tech and growth companies. When employees exercise options, new shares are created, diluting existing shareholders. A company reporting strong basic EPS growth but widening dilution may be less attractive than the headline numbers suggest.
Revenue growth shows a company is expanding its business. EPS growth shows it is becoming more profitable per share. The best investments typically show both metrics growing — expanding revenue paired with improving or maintaining margins.
Basic EPS uses only currently outstanding shares. Diluted EPS adds all potentially dilutive securities — stock options, restricted stock units, convertible bonds — to the share count. Diluted EPS is always equal to or lower than basic EPS and is considered the more conservative measure.
EPS measures earnings available to common shareholders. Preferred stockholders receive their dividends before common shareholders, so those payments must be subtracted from net income to reflect what is actually available per common share.
EPS alone does not tell you if a stock is a good investment — it must be compared to the stock price (P/E ratio) and to the company's growth rate. However, consistently growing EPS over multiple years is a strong positive signal for any company.
Buybacks reduce the number of shares outstanding, increasing EPS even if net income stays flat. A company can report EPS growth purely from buybacks without any operational improvement. Always look at total net income alongside EPS.
Adjusted (non-GAAP) EPS removes one-time items like restructuring charges, asset write-downs, or legal settlements to show underlying operational performance. While useful, it can also be used to paint a rosier picture, so compare it to GAAP EPS.
Publicly traded companies report EPS quarterly in their earnings releases and 10-Q filings, and annually in the 10-K. Trailing twelve months (TTM) EPS sums the last four quarters for a rolling annual figure.
