To keep it practical, we'll show how CBS Corporation's (NYSE:CBS) P/E ratio could help you assess the value on offer. CBS has a P/E ratio of 5.37, based on the last twelve months. That means that at current prices, buyers pay $5.37 for every $1 in trailing yearly profits.

How Do You Calculate CBS's P/E Ratio?

The formula for price to earnings is:

Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)

Or for CBS:

P/E of 5.37 = $44.08 ÷ $8.21 (Based on the trailing twelve months to June 2019.)

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each $1 the company has earned over the last year. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

Does CBS Have A Relatively High Or Low P/E For Its Industry?

One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. The image below shows that CBS has a lower P/E than the average (15) P/E for companies in the media industry.

Its relatively low P/E ratio indicates that CBS shareholders think it will struggle to do as well as other companies in its industry classification. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.

How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. That means unless the share price increases, the P/E will reduce in a few years. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

CBS's 132% EPS improvement over the last year was like bamboo growth after rain; rapid and impressive. The sweetener is that the annual five year growth rate of 23% is also impressive. So I'd be surprised if the P/E ratio was not above average.

Don't Forget: The P/E Does Not Account For Debt or Bank Deposits

Don't forget that the P/E ratio considers market capitalization. In other words, it does not consider any debt or cash that the company may have on the balance sheet. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

How Does CBS's Debt Impact Its P/E Ratio?

CBS has net debt worth 55% of its market capitalization. This is enough debt that you'd have to make some adjustments before using the P/E ratio to compare it to a company with net cash.

The Verdict On CBS's P/E Ratio

CBS trades on a P/E ratio of 5.4, which is below the US market average of 17.4. While the EPS growth last year was strong, the significant debt levels reduce the number of options available to management. The low P/E ratio suggests current market expectations are muted, implying these levels of growth will not continue.
