Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Earnings per share |
|---|---|
| $12M / 5M shares | $2.40 |
| $800k / 400k shares | $2.00 |
| $50M / 20M shares | $2.50 |
| $3M / 2.5M shares | $1.20 |
How This Calculator Works
Enter the company's net income for the period and its shares outstanding. The calculator divides one by the other to give earnings per share, the profit each share earned.
The Formula
Cost per Unit
Total Amount is the full cost or price, Quantity is the number of units it covers
Worked Example
A company with $12 million of net income and 5 million shares outstanding has earnings per share of $2.40. EPS lets profit be compared across companies of very different sizes.
Key Insight
EPS feeds the price-to-earnings ratio, the most common gauge of how expensive a stock is. Watch share count too: buybacks lift EPS by shrinking the denominator, even when total profit has not grown.
Buyback-fueled EPS growth — quality matters
U.S. companies aggressively use share buybacks to grow EPS. Total S&P 500 buybacks averaged ~$800B annually 2018-2024 — substantially more than dividends. A company growing net income 3% while shrinking shares 3% annually shows EPS growth of ~6% — meaningful from an investor perspective but not from an operational perspective.
Buyback economics: companies should repurchase shares when the stock trades below intrinsic value (P/E below the equilibrium P/E that reflects sustainable growth). Companies often repurchase regardless of price — even at high P/E ratios at market peaks. Apple, ExxonMobil, Microsoft, Berkshire Hathaway all have programs that mechanically buy back without much price discipline. This can destroy value when shares are overvalued.
For honest growth analysis: EPS growth = Net Income Growth + Buyback Impact. Separate the two. Companies with 10% EPS growth driven by 5% net income growth + 5% buyback impact are different from companies with 10% EPS growth from pure operational expansion. The latter is higher quality. Most equity-research reports now separate these contributions explicitly.
Adjusted EPS — what's being added back
Most public companies report both GAAP EPS and 'adjusted' EPS (a non-GAAP measure). Adjusted EPS excludes restructuring charges, acquisition-related expenses, amortization of acquired intangibles, stock-based compensation in some cases, and other items management considers non-recurring. Adjusted EPS is consistently higher than GAAP EPS — sometimes by 50-100% for companies with significant non-recurring items.
SEC Regulation G requires public companies to reconcile non-GAAP measures to GAAP. The reconciliation table shows what's being added back; investors can assess whether each adjustment is appropriate. Stock-based compensation is the most controversial — many companies exclude it from adjusted EPS even though it represents real economic dilution. Academic literature (Damodaran, Lakonishok) generally treats SBC as a real cost.
For honest valuation: never compare GAAP EPS to adjusted EPS across companies — the adjustments differ. Use the more conservative GAAP measure when comparing across companies; use adjusted only when comparing the same company across periods where adjustments are consistent. Investor presentations often emphasize adjusted EPS because it's more flattering; sophisticated analysts focus on GAAP for cross-company comparison.

| Company | TTM EPS (GAAP) | P/E | Notes |
|---|---|---|---|
| Apple (AAPL) | ~$6.50 | ~32 | Massive buyback program |
| Microsoft (MSFT) | ~$12.00 | ~35 | |
| Alphabet (GOOGL) | ~$8.00 | ~25 | |
| Meta (META) | ~$20.00 | ~28 | |
| Amazon (AMZN) | ~$5.50 | ~40 | Reinvestment-heavy |
| Tesla (TSLA) | ~$3.50 | ~70 | Growth premium |
| NVIDIA (NVDA) | ~$3.00 | ~50 | AI premium |
| Berkshire Hathaway (BRK.A) | ~$28,000 / share | ~10 | Insurance + diverse |
EPS varies dramatically with share-split history and starting capital structure. EPS levels are not directly comparable across companies — P/E ratios (price relative to EPS) provide normalized comparison. Adjusted EPS typically excludes SBC and one-time items; the gap between GAAP and adjusted varies by company.
Frequently Asked Questions
What is earnings per share?
Earnings per share is net income divided by shares outstanding — the portion of a company's profit allocated to each share of stock.
What is the difference between basic and diluted EPS?
Basic EPS uses the current share count. Diluted EPS also counts shares that could be created from options and convertibles, so it is usually a little lower.
How does EPS relate to the P/E ratio?
The price-to-earnings ratio is the share price divided by EPS. EPS is therefore one of the two inputs behind that widely used valuation measure.
Why can EPS rise without more profit?
Share buybacks reduce the number of shares outstanding, so the same profit is divided among fewer shares — lifting EPS even when net income is flat.
Which share count should I use?
Companies typically report a weighted average of shares outstanding over the period. Use that figure for an EPS that matches official reporting.
When is this calculator unreliable?
When comparing across periods with substantial share repurchases or issuances (buybacks shrink the denominator and inflate EPS without operational improvement; issuances dilute EPS without operational change), when one-time items distort net income (use adjusted or operating EPS), or when comparing companies with very different sizes (large absolute EPS doesn't mean better business — P/E provides the normalized comparison).

Methodology & Review
Earnings per share (EPS) equals net income / weighted average shares outstanding. For diluted EPS (the standard reporting metric), use weighted average shares including dilution from stock options, restricted stock units, convertible debt, and warrants. The calculator returns EPS. EPS growth is the single most-tracked metric in U.S. equity reporting — quarterly earnings releases focus on EPS vs analyst estimates as the headline number. Stock prices typically move 3-8% on EPS surprises (beat or miss by 5%+ vs estimates). RELIABILITY: Reliable as a GAAP-reported metric. Less reliable when comparing across periods with substantial share repurchases (buybacks shrink the denominator, inflating EPS without operational improvement), when one-time items distort net income (use adjusted EPS or operating EPS), or across companies with different capital structures (heavily leveraged companies show higher EPS volatility for the same operational change).
