Earnings Per Share (EPS) Calculator

Earnings per share (EPS) is the portion of a company's net income attributable to each outstanding common share — the most fundamental measure of profitability and stock valuation. Enter net income and weighted-average common shares for basic EPS; add preferred dividends and dilutive securities (convertibles, options, warrants) for diluted EPS; supply the share price and the calculator also returns the price/earnings (P/E) ratio and earnings yield (E/P).

Basic EPS

$2.00

Diluted EPS

$1.92

P/E ratio

15.00

Earnings yield (E/P)

6.67%

Reciprocal of P/E — how much each $ of share price earns.

Earnings to common

$100M

Net income minus preferred dividends, shown in millions.

Formulas per IAS 33 (IFRS) / FASB ASC 260 (US GAAP). The diluted figure here ignores if-converted interest add-backs and is a simplified estimate; refer to the issuer's annual report for filed values.

Formula

Basic EPS = (Net Income − Preferred Dividends) ÷ Weighted-Avg Common Shares Diluted EPS = (Net Income − Preferred Dividends) ÷ (Weighted-Avg + Dilutive Shares) P/E Ratio = Share Price ÷ Basic EPS Earnings Yield (%) = Basic EPS ÷ Share Price × 100

Frequently asked

Which matters more — basic or diluted EPS?

For valuation, use diluted EPS — it captures future per-share dilution from options, convertibles and warrants and is closer to what a shareholder will actually receive per share. Basic EPS reflects the period's actual denominator and is a separate mandatory disclosure under IAS 33 / ASC 260, useful for trend comparison. Rules of thumb: (1) growth / tech names with heavy employee options and convertibles usually have a meaningfully lower diluted figure — use diluted for P/E; (2) cash-rich mature companies with no dilutive instruments have basic = diluted, so either works; (3) when a company posts a loss, all potential common shares are antidilutive by definition and diluted EPS equals basic EPS. The "EPS" headline on Bloomberg / Yahoo Finance is typically GAAP diluted.

Why does my "net income ÷ shares outstanding" not match the reported EPS?

Four common reasons: (1) the numerator must subtract preferred dividends (including accrued amounts on cumulative preferreds), not just net income; (2) the denominator is weighted-average common shares, not period-end shares outstanding — mid-year issues, buybacks and splits change the weighted figure materially; (3) diluted EPS adds potential common shares from convertibles, options and warrants; (4) many companies separately disclose Adjusted EPS that strips out one-offs (non-GAAP), which won't equal the GAAP figure. To reconcile, open the "Earnings per Share" footnote of the 10-K / annual report and read the official numerator and denominator — that's the only version that matches the headline EPS exactly.

What P/E is "reasonable" and does a high P/E mean expensive?

No single P/E is universally "fair" — you have to combine: (1) sector (utilities trade ~12-15x long-term, SaaS 40-80x); (2) earnings growth (PEG = P/E ÷ EPS-growth-% ≈ 1 is the rough yardstick); (3) interest-rate regime (higher rates compress P/E); (4) earnings quality (one-off boosts make P/E look artificially low). Long-run averages: S&P 500 ~15-17x, Hang Seng ~10-12x, Nasdaq ~25-30x. So a software stock at 35x may be fine while a bank at 35x usually signals an earnings collapse (denominator shrank) or unusually high growth expectations. P/Es below 0 or unusually small (< 3) typically signal trouble — losses, big one-time impairments, or a market expecting a sharp earnings drop.
