How EPS turns profit into a per-share number
A company’s total profit is hard to compare across firms — a billion dollars of net income means something very different for a company with ten million shares than for one with ten billion. EPS solves that by reducing profit to a single per-share figure. It starts from net income, removes the dividends contractually owed to preferred shareholders, and divides the remainder by the common shares outstanding. The result is the earnings that genuinely belong to each common share — the foundation that valuation multiples like the P/E and PEG ratios are built on.
The EPS formula
EPS = (Net income − Preferred dividends) ÷ Shares outstanding
where Net income is total profit after tax,Preferred dividends are the amounts owed to preferred shareholders before common holders are paid, andShares outstanding is the number of common shares. The numerator — net income minus preferred dividends — is the earnings available to common shareholders.
What makes this calculator different
- It removes preferred dividends for you. Many quick calculators just divide net income by shares; this one subtracts preferred dividends first, so the numerator is the earnings actually available to common shareholders.
- It works from raw net income. Enter the figure straight off the income statement — no need to pre-compute “earnings to common” yourself.
- It shows earnings-to-common. The intermediate step — net income less preferred dividends — is surfaced, not hidden, so you can see exactly what is being divided.
- It links into valuation. EPS is the gateway to the ratios investors actually use, so the result feeds naturally into the P/E and PEG calculations.
Once you have an EPS figure, the natural next step is to compare it to price. Drop it into theP/E ratio calculatorto see how much the market is paying for each dollar of those earnings.
Frequently asked questions
What is EPS and what is the formula?+
Earnings per share (EPS) measures the portion of a company’s profit allocated to each outstanding common share. The formula is EPS = (Net income − Preferred dividends) ÷ Shares outstanding. You start with net income, strip out the dividends owed to preferred shareholders (since those are not available to common holders), and divide what remains by the number of common shares. The result is a single per-share figure that lets you compare profitability across companies of very different sizes.
What is the difference between basic and diluted EPS?+
Basic EPS divides earnings available to common shareholders by the actual shares outstanding today. Diluted EPS goes further and counts potential shares — stock options, warrants, and convertible securities — as if they had already been exercised or converted. Because dilution increases the share count, diluted EPS is always equal to or lower than basic EPS, and it gives a more conservative picture of per-share earnings.
Why do you subtract preferred dividends?+
Preferred shareholders have a higher claim on a company’s profits than common shareholders and are paid their dividends first. Net income on its own includes money that is contractually owed to those preferred holders, so it overstates what is actually left for common shares. Subtracting preferred dividends isolates the earnings genuinely attributable to common shareholders — the figure that belongs in the EPS numerator.
What is a good EPS?+
There is no universal “good” EPS number, because the figure is only meaningful relative to the share price and watched over time. A $5 EPS sounds large but tells you nothing until you know what investors paid for the stock. A higher EPS is not automatically better: it can reflect share buybacks or one-off gains rather than genuine growth. The useful signals are a rising EPS trend and an EPS that looks attractive against the price you would pay for it.
How does EPS relate to the P/E ratio?+
EPS is the denominator of the price-to-earnings (P/E) ratio: P/E = Price ÷ EPS. EPS tells you how much a company earns per share, while the P/E ratio tells you how much the market is willing to pay for each dollar of those earnings. The two are inseparable — you cannot interpret a P/E without knowing the EPS behind it, and EPS becomes a valuation tool only once you compare it to price.
Disclaimer: This calculator is foreducation and illustration only. EPS is a single accounting measure and does not capture a company’s full financial picture; figures can be affected by buybacks, one-off items, and the difference between basic and diluted share counts.
