Price to Book P/B Ratio Calculator

Calculate price to book ratio (P/B) quickly and easily. With this free online calculator you can calculate the price to book ratio by entering the current share price and the book value per share. You can use the second calculator to determine the book value per share. The price book ratio is one of the most important metrics in the valuation of stocks. The P/B Ratio should be below 1 to show an undervalued stock.

To calculate the Price to Book Ratio (P/B), you need to insert the current share price and the book value per share. You can find the current share price simply via a Google search by entering the "name of the share" and "share price". Google then shows the current share price directly. To find out the book value per share, you can use the calculator below. Some stock data websites such as Yahoo Finance already offer the book value per share in the "Fundamental" category. In our premium membership, we have already calculated the P/B Ratio for more than 35,000 shares. In addition to the Price to Book Ratio (P/B), you will receive all other important ratios for fundamental Analysis.

Formula to calculate the Price to Book (P/B) Ratio

The formula for calculating the Price to Book Ratio (P/B) divides the market capitalization (current share price times the number of shares issued) by the book value. The result is the price / book ratio or P/B for short.

 

Price to Book Ratio = Market Capitalization / Book Value 

 

Alternatively, the price to book ratio P/B can also be calculated for the individual stock by dividing the current share price by the book value per share. The book value per share is obtained by dividing the equity (book value) by the number of shares issued.

 

Price to Book Ratio = share price / book value per share

 

In our book value calculator, we use the second variant. An auxiliary calculator is available for this purpose, which calculates the book value per share and then adds it to the main computer at the top. You can usually find data such as book value, number of shares issued, share price and book value per share on relevant stock websites such as: Yahoo Finance. Enter the name of the stock whose price / book value ratio (P/B) you would like to know. Under the tab "Fundamental key figures" you will find all the financial key figures that you need to calculate the price / book ratio (P/B). Enter these key figures here in our calculator and you will receive a reliable Price to Book Ratio.

Book Value per Share Calculator

To find out the book value per share, you need to enter the total equity or book value and the number of shares in the company issued into the second calculator. Equity is the capital brought into the company by shareholders and owners and is the result of the positive difference between assets and debts. The number of shares is the sum of all shares issued. This information can also be found quickly using a Google search. These key financial figures can also be found in the annual report of the respective company, which can also be easily found on Google with the "name of the company" and the keyword "Investors Relations". Relevant stock information websites also show the necessary key figures. The book value per share is also shown in our premium tool for more than 35000 stocks updated every day.

whats a good Price to Book P/B Ratio?

A Price to Book ratio (P/B) below 1 shows an undervalued stock. Since the book value represents the company's equity, if the P/B is below 1, the company cannot even expect the value of its net assets. Example: A public company has assets of 10 million Euro: Cash, real estate, machines and patents. In addition, there are 5 million Euro in debt.

It follows that the company's equity amounts to 5 million Euro. (Equity = Assets - Debt). If the share is quoted at 5 euros each and 1 million shares have been issued, the company's market capitalization is 5 million euros. The market capitalization (share price times the number of shares issued) would therefore correspond to equity, so the price of the share also corresponds to the book value per share. The price to book ratio would be 1 and the share would be valued fairly based on the price to book ratio (P/B).

If the P/B would be below 1, the market price would be lower than the net worth and the public company would be undervalued. If you buy shares with a P/B ratio of less than 1, you pay less for the company than it is actually worth on paper. If the company were to shut down and all equipment, machinery, patents, real estate, etc. were sold and the cash split up, you would still get more money than you spent buying the stock.

What does the Price to Book P/B Ratio say?

A share that has a Price to Book P/B below 1 is not automatically a good stock to buy. A low P/B can indicate both a cheap company and a company in serious trouble. A first look at the P/B can pay off to clarify whether the company is worth a closer look. Subsequently, however, it must be clarified why the company is valued so favorably. For this purpose, you can incorporate further key figures and ratios into the evaluation process. At Fairvalue-Calculator.com we have many other calculators that can help with stock analysis.

Only the holistic analysis of the public company reveals whether a company is really cheap or expensive. In the calculator for the extended fair value, for example, 7 key figures flow into the calculator at the same time in order to obtain a more meaningful result. In the premium membership, we have also automated these calculators for more than 35,000 shares. How to find cheap stocks with ease.

Conclusion:

The Price to Book Ratio (P/B) is one of the most important key figures in the valuation of stocks. Unfortunately, the price-to-book ratio (P/B), which is shown on stock portals, is often out of date and not always correct. Only if you calculate the P/B yourself do you know where the data for the calculation come from and how up-to-date the share price used is. A P/B of less than 1 can both indicate a cheap company and indicate serious problems in the company.

The P/B is therefore not suitable as the sole valuation indicator and only the joint consideration of various indicators provides information about whether a share is actually a bargain. We have also created additional calculators and explanations for other key figures. In the overview of all calculators you will find other useful calculators that facilitate the valuation process of stocks.

Personal Experience with the P/B Ratio as Valuation Method

The price to book ratio (P/B) together with the price / earnings ratio (P/E) and the price / sales ratio (P/S) can display not only cheap stocks but also cheap sectors, especially in a cross-sector view. The average values of these key figures indicate favorable industries, in which, as a result, cheap stocks can usually also be found. An industry-wide crisis such as a rise in the price of raw materials or temporary changes in the market environment of an industry can temporarily devalue an entire industry.

As a result, these industries often show a low price / book value ratio. In the industry, you can then look for stocks that actually show little real economic loss in the industry. However, the stock price of these companies is devalued because the entire industry is currently suffering "image damage" and is not "in vogue" due to negative reporting. These investments can then be particularly lucrative!

Practical Example of using the P/B Ratio

In 2020, the share price of the car maker Tesla skyrocketed. Like a magnet, this stock soaked up capital and made Elon Musk, the founder of Tesla Motors, the richest man in the world. The Tesla hype has caused the valuation of Tesla shares to explode. At price highs, a price / book ratio of over 40 was accepted for Tesla in order to participate in the hype.

Almost quietly and secretly, all German carmakers were devalued and the shares of Daimler and VW fell parallel to the rise of Tesla. Daimler and VW were dirt cheap with a P/B under 1. It seemed as if the old German car giants were not able to bring a decent electric car onto the market, the market participants lacked a raging story with growth fantasies. In addition, VW suffered from the final effects of the Dieselgate scandal. A double bargain?

Of course, one of the largest automakers in the world with an excellent sales network and the best engineers in the world is capable of producing at least as good electric vehicles - if they have to. With the introduction of new electric models from Mercedes and VW, the throne of the electric car pioneer is crumbling. The true intrinsic value of a stock tends to come to light sooner or later.

In 2021, Tesla's share price shows a decline and the German carmakers were able to catch up. The P/B has reliably indicated a current bargain in the car industry and in the individual stocks. In this situation, of course, one had to assess whether a "Nokia effect" could occur and the German carmaker would completely disappear from the scene and Tesla would become the new Apple of the automotive industry. The joint consideration of the price / earnings ratio shows, however, that even in these crisis years, Volkswagen's profit could always be increased. The further course of this competition will show us who will prevail.

The price of the Daimler and VW shares recovered strongly. In order to recognize such industry effects, we have set up an industry overview in the premium tool of the Fairvalue Calculator, which shows the average P/E, P/B and P/S figures for each industry. If an industry is valued favorably, the industry turns green and within seconds you can see in which industries bargains are very likely to be found.

Industries with a low Price to Book (P/B) Ratio 2021

The following industries currently have a low P/B ratio. The following list shows all sectors with a low price / book ratio and also gives the reason for the depreciation of the P/B. You can decide for yourself whether these are bargain industries or whether these industries are in a real crisis:

  • Banks with an average P/B of 0.99 (due to the corona pandemic, higher loan defaults are feared)
  • Insurance companies with an average P/B of 1.16 (here, too, higher insurance costs are feared)
  • Oil and natural gas with an average P/B of 1.33 (Oil and gas companies are cheap due to the drop in the price of oil)
  • Travel and tourism with a P/B of 1.46 (traveling is virtually impossible during the corona pandemic)

Assuming that these temporary effects can be overcome or even made up for, the P/B will help to identify such special situations and, if necessary, to find undervalued stocks from these sectors. To find these kind of Sectors and industries use the Premium Tools on this site.
