EPS (Earnings Per Share) Calculator

Earnings per share strips a company's profit down to what it earned for each share of common stock, and this tool reports both the basic and diluted versions of that figure. Because EPS sits at the center of how investors gauge profitability and how analysts frame valuations heading into 2026, having both numbers side by side makes comparing opportunities far easier.

Basic EPS divides net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS goes a step further by assuming that dilutive securities, such as stock options and convertible bonds, are converted into shares, which enlarges the denominator and lowers the result. That wider denominator is exactly why diluted EPS gives the more cautious read on per-share earnings.

Treating basic and diluted EPS as interchangeable hides real risk, since the gap between them shows how much existing holders could be diluted later. One detail trips up many calculations: the share figure should be the weighted average across the period, not the count sitting on the books at year-end, or the earnings will be measured against the wrong base.
