This calculator gives an estimate for educational use only and is not investment advice. Reported EPS depends on accounting choices, one-off items, share buybacks and the exact weighted average used by the company, and diluted EPS can differ from the basic figure shown here. Always read the audited financial statements and speak to a qualified adviser before making any investment decision.
Enter net income, any preferred dividends, and the weighted average shares outstanding to find EPS.
Earnings per share (EPS) tells you how much of a company’s profit is attributable to each share of common stock. It is one of the most widely watched numbers in investing, feeding directly into the price-to-earnings (P/E) ratio. Enter the net income, any preferred dividends, and the weighted average shares outstanding, and this calculator returns the basic EPS along with the earnings available to common shareholders.
What is the EPS Calculator?
Earnings per share is the portion of a company’s net profit allocated to each outstanding share of common stock. The basic formula is EPS = (net income − preferred dividends) ÷ weighted average shares outstanding. Preferred dividends are subtracted first because that money belongs to preferred shareholders, not to common holders, so it is not part of the profit the common shares can claim.
The denominator is the weighted average number of shares, not the share count on the last day of the year. Companies issue and buy back shares throughout a period, so using a simple year-end figure would distort the result. The weighted average reflects how many shares were actually outstanding over time: if a company starts the year with 1,000,000 shares and issues 200,000 more halfway through, the weighted average is roughly 1,100,000, not 1,200,000.
What you get from this formula is basic EPS. Companies also report diluted EPS, which assumes that stock options, warrants and convertible securities are exercised, increasing the share count and usually lowering EPS. Diluted EPS is the more conservative figure and is the one most analysts focus on. EPS on its own says little about value, a high-priced stock and a cheap one can have identical EPS, which is why it is almost always paired with the P/E ratio to judge whether a share is expensive relative to its earnings.
When to use it
- Calculating basic EPS from a company’s income statement when you only have net income and the share count.
- Feeding EPS into a price-to-earnings (P/E) ratio to gauge how a stock is valued.
- Comparing the profitability per share of two companies in the same industry.
- Checking a reported EPS figure, or stripping out preferred dividends to see earnings available to common holders.
How to use the EPS Calculator
- Enter the company’s net income (profit after tax) for the period.
- Enter total preferred dividends, or leave it blank if the company has no preferred stock.
- Enter the weighted average number of common shares outstanding.
- Read off the earnings per share and the earnings available to common shareholders.
Formula & method
Worked examples
A company reports net income of $5,000,000, pays $200,000 in preferred dividends, and has 2,000,000 weighted average common shares.
- Earnings for common = 5,000,000 − 200,000 = 4,800,000
- EPS = 4,800,000 ÷ 2,000,000
- EPS = 2.40
Result: EPS = $2.40 (earnings available to common holders = $4,800,000)
A company has net income of $1,200,000, no preferred stock, and 800,000 weighted average common shares.
- Earnings for common = 1,200,000 − 0 = 1,200,000
- EPS = 1,200,000 ÷ 800,000
- EPS = 1.50
Result: EPS = $1.50 (no preferred dividends to subtract)
How EPS moves with net income and share count (no preferred dividends)
| Net income | Weighted avg shares | EPS |
|---|---|---|
| $1,000,000 | 500,000 | $2.00 |
| $1,000,000 | 1,000,000 | $1.00 |
| $2,000,000 | 1,000,000 | $2.00 |
| $5,000,000 | 2,000,000 | $2.50 |
| $5,000,000 | 4,000,000 | $1.25 |
Basic EPS versus diluted EPS at a glance
| Measure | Share count used | Typical use |
|---|---|---|
| Basic EPS | Weighted average common shares only | Simple per-share profit |
| Diluted EPS | Includes options, warrants, convertibles | Conservative, analyst-preferred figure |
Common mistakes to avoid
- Forgetting to subtract preferred dividends. Preferred dividends belong to preferred shareholders, not common ones. If you divide raw net income by common shares without subtracting them, you overstate EPS for the common holders.
- Using year-end shares instead of the weighted average. Shares outstanding change as companies issue or buy back stock. Using the final-day count rather than the weighted average over the period distorts EPS, sometimes significantly.
- Confusing basic EPS with diluted EPS. Basic EPS ignores potential shares from options and convertibles. Diluted EPS assumes they convert, raising the share count and usually lowering EPS. Compare like with like across companies.
- Reading EPS as a measure of value on its own. A high EPS does not mean a stock is cheap, nor a low EPS expensive. EPS only becomes a value signal when set against the share price, usually through the P/E ratio.
Glossary
- Earnings per share (EPS)
- The portion of a company’s net profit allocated to each outstanding share of common stock.
- Net income
- A company’s total profit after all expenses, interest and taxes have been deducted from revenue.
- Preferred dividends
- Dividends paid to preferred shareholders, who rank ahead of common holders and are subtracted before calculating EPS for common shares.
- Weighted average shares
- The average number of common shares outstanding over a period, weighted by how long each amount was in issue.
- Diluted EPS
- EPS recalculated as if all options, warrants and convertible securities were exercised, increasing the share count.
- P/E ratio
- Price-to-earnings ratio: the share price divided by EPS, used to judge how a stock is valued relative to its earnings.
Frequently asked questions
What is the formula for earnings per share?
Basic EPS = (net income − preferred dividends) ÷ weighted average shares outstanding. You subtract preferred dividends because that profit belongs to preferred shareholders, then divide the remaining earnings by the average number of common shares that were outstanding during the period.
Why do you subtract preferred dividends?
EPS measures the profit available to common shareholders. Preferred shareholders have a prior claim on earnings through their dividends, so that amount is removed first. What is left is the profit the common shares can actually claim, which is then spread across those shares.
What is the difference between basic and diluted EPS?
Basic EPS uses only the common shares actually outstanding. Diluted EPS assumes that stock options, warrants and convertible securities are exercised, which increases the share count and usually lowers EPS. Diluted EPS is the more conservative figure most analysts rely on.
What is a good EPS?
There is no universal threshold. EPS depends on company size and share count, so a small firm and a large one can have very different EPS while being equally profitable. What matters more is whether EPS is growing over time and how it compares to the share price through the P/E ratio.
Why use the weighted average number of shares?
Companies issue and repurchase shares throughout the year. The weighted average reflects how many shares were outstanding for how long, giving a fairer denominator than the count on a single day, which could overstate or understate EPS.
Can EPS be negative?
Yes. If a company reports a net loss, or if preferred dividends exceed net income, the earnings available to common shareholders are negative and so is EPS. A negative EPS signals the business lost money for common holders over the period.
