Example of Price to Book Value Formula

Let’s take an example to find out the price-to-book value ratio for a company X: –

The book value per share can be found by dividing the Book Value of the Equity of the company by the total shares outstanding in the market.

Book Value of Equity = Total Assets – Total Liabilities

Book Value of Equity = Total Shareholder’s equity in the company

Assuming the Book Value of Assets for company X = Rs 30 million

Total Shares Outstanding in the market = 1 million

Market Share price = Rs 100


Book Value per share is calculated as

Book Value per share = Book Value of Equity / Total Shares Outstanding

Book Value per share = 30 / 1

Book Value per share = Rs 30 per share

Price to Book Value is calculated as

Price to Book Value = Market price per share / Book Value per share

Price to Book Value = Rs 100 / Rs 30

Price to Book Value = 3.33

Taking assumed values for the following: –


P/B Value






Industry Average


A comparison of P/B is generally made between the peer group and the industry average. Company X has a P/B lower than the industry average and lower than its peer group, which highlights that X might be undervalued. Company Y has P/B equal to industry-valued, and it can be assumed that Y’s stock is correctly valued. Company Z has P/B greater than its peer group and higher than the industry average. Hence it can be assumed that the company’s stock is overvalued in the market. But it must be remembered that P/B is one of the indicators for the valuation of a company or stock. Still, it should not be the sole criterion to judge whether a stock is overvalued or undervalued.


Price to Book Value alone indicates nothing substantial about the company’s financial health. It is used for relative valuation, where companies operating in a similar industry can be compared. Often firms with low price-to-book values compared to their peers are considered value stocks, while firms with a high price-to-book value are considered growth stocks. The more optimistic the investors are about the firm’s future growth, the greater its price-to-book value ratio.

Price to Book Value is generally the preferred metric for financial companies, banks, etc. This is because, due to regulations, they have to mark to market their assets regularly; their book value accurately reflects the market value of their assets. This is not true for other companies; hence, the price-to-book value becomes an essential metric when comparing financial companies.

Adjustments are also made to the P/B ratio while comparing different stocks. One of the adjustments made is using tangible book value, where intangible assets are subtracted from the book value of equity. Goodwill and patents are a few examples of intangible assets which need to be removed from the book value of equity for better comparison. Also, another example of adjustments is the removal of off-balance sheet assets and liabilities. Inventory adjustments are also required while comparing the P/B ratios of companies in the same industry. A company using First In First Out (FIFO) for inventory valuation cannot be compared with another company in a similar industry using Last In First Out (LIFO) for its inventory valuation.

Advantages of Price to Book Value Formula

Book value is an amount that is generally positive even when the company reports a loss in its Profit and Loss statement. Hence P/B is an effective measure in comparing companies when P/E cannot be used for these firms.

Book value does not frequently change, which is useful in comparing companies whose EPS is particularly low, high, or volatile.

Book value is an effective measure of valuing banks, financial companies, etc., since they are marked to market frequently and give an apt comparison.

P/B measure is effective in the valuation of companies that are about to go out of business.

P/B can be useful in valuing companies expected to go out of business.

Research suggests that P/B explains the dissimilarities in long-run average stock returns.

There are sometimes significant differences in the business models of various firms operating in the same industry. For example, a company might be outsourcing its production. Hence, this firm will have fewer assets and lower book value, which would overstate its P/B value than another company doing its in-house production.

Also, various accounting conventions used by different companies can conceal the true investment in the company by its shareholders, which decreases the comparability of P/B across firms and countries. For example: – In the United States, the convention followed is that Research and Development costs are expensed, which can understate capital investment.

External factors such as inflation and technological changes can significantly alter the book and market value of assets, decreasing the importance of book value as a measure of shareholder’s investment. This would decrease the comparability between firms using the P/B ratio.

Value investors generally use the P/B ratio since the basic foundational belief of value investing is that markets are inefficient. Hence, the actual book value of a company is not priced into the market price of the share. A P/B ratio below the market averages may indicate that a firm is undervalued and represents a buying opportunity.
