P/E calculator
Divide a share price you enter by earnings per share, or load diluted EPS for any of the companies Ticker Sage covers straight from its 10-K.
An illustration, not a valuation. This calculator divides a price you enter by earnings per share. It doesn't say whether any price is high, low or fair, and it doesn't predict anything.
The formula
P/E ratio = share price ÷ earnings per share
Earnings yield = earnings per share ÷ share price × 100
Where the EPS comes from
Each company's 10-K reports diluted and basic EPS for its last fiscal year at the bottom of the income statement, and every preset here links to that filing. Apple's diluted EPS for fiscal 2025 was $7.46: at a price you type, the P/E is that price divided by $7.46.

Reading the result
What a P/E ratio is covers what the ratio measures and what it leaves out, and Earnings per share, basic and diluted explains the two EPS figures.
Common questions
How do you calculate a P/E ratio?
Divide the share price by earnings per share. With Apple's fiscal 2025 diluted EPS of $7.46, the P/E is the price divided by $7.46. Source: Apple 10-K for fiscal 2025.
Why does the calculator use the last fiscal year?
Because that's the EPS a company reports in its 10-K, the audited annual report. A trailing twelve-month P/E adds up the last four quarters instead, so it can differ from the fiscal-year figure.
Why does it show n/m?
When EPS is zero or negative the company didn't earn a profit for the year, and a P/E would be meaningless, so the calculator shows n/m (not meaningful) instead of a number.
What is the earnings yield?
Earnings per share divided by the share price, as a percentage. It's the P/E turned upside down: a P/E of 25 is an earnings yield of 4%.
Does a low P/E mean a stock is cheap?
Not on its own. A low P/E can reflect slow expected growth, earnings at a cyclical high, one-time gains, debt or other risks. The ratio is a description of price against one year of profit, not a judgment.
