What is the Price to Earnings Ratio Calculator?
Calculate P/E from price and earnings per share. To use the Price to Earnings Ratio Calculator, enter share price, eps; it returns p/e ratio, earnings yield, and shows them instantly as you type.
Valuing a stock step by step
Begin with the P/E ratio and PEG ratio to see what the market pays for earnings and growth. Then check quality with ROE and ROIC, and compare ROIC with the WACC.
For a second opinion, estimate intrinsic value with the Dividend Discount Model Calculator or the Graham Number Calculator, then compute the margin of safety against today’s price.
- Returns. EPS, EPS growth, dividend yield and payout ratio measure what shareholders earn.
- Risk. Beta, unlevered beta and portfolio beta measure sensitivity to the market.
- Position tools. Stock average, stock split and market cap calculators keep your records straight.
How to use the Price to Earnings Ratio Calculator

Formula and how it works
Example with real numbers
Here is the Price to Earnings Ratio Calculator using the default values shown in the calculator above:
Inputs
| Share price ($) | 120 |
|---|---|
| EPS ($) | 6 |
Results
| P/E ratio | 20× |
|---|---|
| Earnings yield | 5% |
With these inputs the calculator returns P/E ratio: 20×. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Share price ($) from 120 to 144 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| P/E ratio | 20× | 24× | +20% |
| Earnings yield | 5% | 4.17% | -16.7% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.

Frequently asked questions
What is a good P/E?
It depends on growth and sector; the long-run market average is roughly 15 to 20.
Is a high dividend yield good?
Not automatically. A very high yield can signal a falling price or a dividend that may be cut.
Are valuation results investment advice?
No. They are model outputs from the figures you enter. Test a range of assumptions and speak with a licensed adviser before investing.
Are the results guaranteed?
No. Results depend entirely on the numbers you enter and the formulas shown on this page. Please do not make financial decisions based on them alone; confirm important figures with a licensed professional.
