What is the price to earnings ratio?
Price/earnings ratio  often called the price to earnings ratio or the P/E ratio  is a finance indicator that measures a company's stock price concerning earnings per share. Simply put, it shows the balance between price and earnings from the stocks. Thanks to this ratio, we can see how profitable it is to buy shares of a specific company.
Also, we can use the P/E ratio to determine if shares are over or undervalued. For example, if you consider two companies in the same industry but with entirely different values of the P/E ratio, it might mean that the valuation of one of them is not believable.

Price/earnings ratio formula
To calculate the price/earnings ratio, you need two elements:
 Price per share  the market price of a stock. This value heavily depends on the supply and demand of the market.
 Earnings per share  the profit that a company gains from each outstanding share of common stock. If a company doesn't have any net income but only net losses, it won't have a P/E ratio. Visit our earnings per share calculator to learn more about earnings per share.
If you want to know what is the P/E ratio of a certain company, you need to divide the share price by the earnings according to the P/E ratio formula below:
P/E ratio = share price / earnings per share
.
How to calculate the price/earnings ratio?
Let's analyze the example of a company that has been on the market for several years. To find out what is their price/earnings ratio, you need to do the following:

Determine the market share price. Let's assume that it is equal to $25.

Determine the earnings per share over the last 12 months. In our example, we'll set this value to $1.80.

Use the price/earnings ratio formula:
P/E ratio = 25/1.80 = 13.90
 As you can see, the P/E ratio in our example is roughly 14x the earnings.
Of course, you could simply input the values in the pricetoearnings ratio calculator and have the value calculated for you 😉.
Interpreting the results of P/E ratio formula
Now that we have arrived at a result, we can try to interpret it. As a general rule, a company with a high P/E ratio is considered more profitable on the market  it means that investors are willing to pay more per share because they anticipate fast growth and higher future earnings.
To determine whether the price/earnings ratio is high or low, you need to compare it with the P/E ratios of other companies in the same industry. For instance, if your company has a P/E of 14x the earnings and most of its competitors have 12x the earnings, you could say that your business is considered more valuable by the market.
