## P/E Ratio Formula and Calculation

Price-earnings ratio can be calculated by dividing the current stock price of the company by the earnings per share (EPS) of the company.

P/E ratio = Market Price Per Share / Earnings Per Share (EPS)

To calculate the price-earnings ratio you need current stock price that can be found through the stock exchange, where the stock is listed. You can get the earnings per share (EPS) from the income statement.

### Example

Suppose a company’s current stock price is quoting at $100 and the basic earnings per share of the company is $10. So P/E ratio of that particular company = $100/$10 = 10.

## What Does The P/E Ratio Tells About A Stock?

The price-earnings ration varies across different industries, for example P/E ratio for IT industry is higher than the commodity industry, because of future demand and growth.

The P/E ratio generally gives the idea about the stock, whether it is overvalued or undervalued or trading with good valuation by observing its past industry P/E.

### High P/E

A stock with higher P/E is considered as a growth stock or the investors are expecting growth with in the company in coming years. But, in some cases with decrease in earnings of a stock with good asset quality and fundamental quality leads a higher P/E. However, investing in these type of stocks is quite risky as their behavior is unpredictable. So investment in these type of stock is not recommended, unless a its quality stock.

### Lower P/E

Lower P/E ratio of a stock is generally considered as a under-valued stock or investors are expecting a slowdown in the company’s earnings. Sometimes because of some corporate governance issue or regulatory issue stock price goes down resulting lower P/E.

Company with a good fundamental having lower P/E is considered as value investing, unless the industry is facing a slowdown. The low P/E stocks can be found in mature industries or those who pay a higher rate of dividends.

### Justified P/E

Justified P/E is quite tricky to calculate. Here is the formula for the justified P/E. Justified P/E = Dividend Payout Ratio / R – G Where, R = Required Rate of Return G= Sustainable Growth Rate
