For example, the price-to-earnings (P/E) ratio provides the implied valuation of a company based on its current earnings, or accounting profitability. As a result, a company will have more than one P/E ratio, so investors must be careful to compare the same P/E when evaluating and comparing different stocks. Earnings yield is sometimes used to evaluate return on investment, whereas the P/E ratio is largely concerned with stock valuation and estimating changes. In other words, we can say that an investor who purchases the company’s shares is willing to pay $20 for each dollar of earnings. The P/E ratio should be compared with the share market as a whole, focusing on other companies in the same industry as well as the same company over the last few years.
How to Calculate P/E Ratio
Hence, it’s sometimes called the price multiple because it shows how much investors are willing to pay per dollar of earnings. If a company trades at a P/E multiple of 20x, investors are paying $20 for $1 of current earnings. The trailing P/E ratio will change as the price of a company’s stock moves because earnings are released only each quarter, while stocks trade whenever the market is open. If the forward P/E ratio is lower than the trailing P/E ratio, analysts are expecting earnings to increase; if the forward P/E is higher than the current P/E ratio, analysts expect programmable brick utilities them to decline. The P/E Ratio—or “Price-Earnings Ratio”—is a common valuation multiple that compares the current stock price of a company to its earnings per share (EPS). A company’s P/E ratio is calculated by dividing the stock price with earnings per share (EPS).
What Is the Price-to-Earnings (P/E) Ratio?
The basic P/E formula takes the current stock price and EPS to find the current P/E. EPS is found by taking earnings from the last twelve months divided by the weighted average shares outstanding. Earnings can be normalized for unusual or one-off items that can impact earnings abnormally.
- If a company’s earnings per share increases but its price-earnings ratio remains constant, its share price is likely to increase.
- In the next step, one input for calculating the P/E ratio is diluted EPS, which we’ll compute by dividing net income in both periods (i.e. LTM and NTM basis) by the diluted share count.
- The P/E ratio is derived by taking the price of a share over its estimated earnings.
- The last alternative to consider is the enterprise value-to-EBITDA (EV/EBITDA) ratio.

The P/E ratio seems like a straightforward calculation, but what you use for earnings can be tricky. For one thing, earnings are reported by each company, and accounting practices are not the same across the board.
That is, the P/E ratio shows what the market is willing to pay today for the accounting equation may be expressed as a stock based on its past or future earnings. A high P/E ratio could signal that a stock’s price is high relative to earnings and is overvalued. Conversely, a low P/E could indicate that the stock price is low relative to earnings. The P/E ratio, often referred to as the “price-earnings ratio”, measures a company’s current stock price relative to its earnings per share (EPS).
Or if you’re looking at past data for one company, a higher number could mean it’s no longer a bargain. It doesn’t account for future earnings growth, can be influenced by accounting practices, and may not be comparable across different industries. It also doesn’t consider other financial aspects such as debt levels, cash flow, or the quality of earnings. For example, in February 2024, the Communications Services Select Sector Index had a P/E of 17.60, while it was 29.72 for the Technology Select Sector Index.
Understanding the P/E Ratio
The P/E ratio helps compare companies within the same industry, like an insurance company to an insurance company or telecom to telecom. However, it should be used with other financial measures since it doesn’t account for future growth prospects, debt levels, or industry-specific factors. The PEG ratio measures the relationship between the price/earnings ratio and earnings growth to give investors a complete picture.

The company’s price-to-earnings ratio is 10x, which we determined by dividing its current stock price by its diluted earnings per share (EPS). The formula for calculating the P/E ratio—or price-earnings ratio—is equal to the current stock price divided by earnings per share (EPS). In other words, you shouldn’t just zero in on the P/E ratio when you’re deciding whether to buy shares. There are many other metrics to consider, including earnings charts, sales figures and other fundamentals of a company. You can also look at the dividend rate if you’re going for dividend investing.
However, if the business is solid, the one with more debt could have higher earnings because of the risks it has taken. A main limitation of using P/E ratios is for comparing the P/E ratios of companies from varied sectors. Companies’ valuation and growth rates often vary wildly between industries because of how and when the firms earn their money.
As such, one should only use P/E as a comparative tool when considering companies in the same sector because this is the only kind that will provide worthwhile results. For example, comparing the P/E ratios of a retail company and the P/E of an oil and gas drilling company could suggest one is the superior investment, but that’s not a cogent conclusion. An individual company’s high P/E ratio, for example, would be less cause for concern when the entire sector has high P/E ratios. The earnings yield is also helpful when a company has zero or negative earnings. Since this is common among high-tech, high-growth, or startup companies, EPS will be negative and listed as an undefined P/E ratio (denoted as N/A). If a company has negative earnings, however, it would have a negative earnings yield, which can be used for comparison.
As stated earlier, there is usually an acceptable range for the P/E ratio that must be researched and considered carefully for the purposes of investment. It is, therefore, also referred to as the earnings multiple and price multiple.

Investors might also compare the current P/E to the bottom side of the range, measuring how close the current P/E is to the historic low.

To account for the fact that a company could’ve issued potentially dilutive securities in the past, the diluted share count should be used — otherwise, the EPS figure is likely to be overstated.
Another alternative is the price-to-sales (P/S) ratio which compares a company’s stock price to its revenues. This ratio is useful for evaluating companies that may not be profitable yet or are in industries with volatile earnings. Earnings yields are useful if you’re concerned about the rate of return on investment. For equity investors who earn periodic investment income, this may be a secondary concern. This is why many investors may prefer value-based measures like the P/E ratio or stocks. Bank of America’s higher P/E ratio might mean investors expected higher earnings growth in the future compared to JPMorgan and the overall market.
