Price to Book Ratio Calculator – PB Ration

A Price to Book Ratio Calculator is a financial calculator that assists you in evaluating the market value of a company to measure its book value. The price-to-book (P/B) ratio is a popular stock market valuation metric. The ratios are primarily used to compare companies that possess significant tangible assets, such as the banking, insurance, and manufacturing sector.

The P/B ratio evaluates the information on the current price of a stock in comparison to its book value. Book value, typically, is the difference between a firm’s total assets and total liabilities as reported on the balance sheet.

A company with a low P/B ratio is comparatively cheaper to buy, whereas, a higher ratio indicates that the stock is expensive. Nevertheless, the value should not be considered on its own to identify the right time to buy or sell.

How to Use the Price to Book Ratio Calculator

Steps to identify Price to Book Ratio:

1. Input the current share price: Add the current market price of a single share of the company.

2. Input the book value per share: Insert the book value per share of the company from the financial statements or calculate the value using shareholders’ equity and outstanding shares

3. Hit the calculate tab: The calculator will prompt the results of the calculation.

4. Interpret the result: Use the results to analyse the ratio in determining how the market price of the stock compares to the book value.

For example: If the share price of the company is at ₹200 per share and the book value is at ₹100 per share the calculator will show a P/B ratio of 2.0.

Price to Book Ratio Formula

To determine the Price-to-Book ratio use the formula below:

$$

\\text{P/B Ratio}=\\frac{\\text{Market Price Per Share}}{\\text{Book Value Per Share}}

$$

Book Value Per Share:

$$

\\text{Book Value Per Share}=

\\frac{\\text{Total Assets}-\\text{Total Liabilities}}{\\text{Outstanding Shares}}

$$

In practice, however, the numerator in the book value per share calculation is the shareholders’ equity found on the firm’s balance sheet.

Example Calculation

Assuming the following financial information for a company:

• Current share price: ₹300
• Total assets: ₹50 crore
• Total liabilities: ₹20 crore
• Outstanding shares: 10 lakh
• The steps to analyse the P/B ratio are as follows:
• Step 1: Calculate Book Value per Share.
• Book value = ₹50 crore − ₹20 crore = ₹30 crore.
• Book value per share = ₹30 crore ÷ 10 lakh = ₹300.
• Step 2: Calculate the P/B ratio.
• P/B ratio = ₹300 ÷ ₹300 = 1.0

The company’s P/B ratio is at a 1.0, implying that the company’s shares are trading at a price equivalent to the book value per share.

Understanding Your Result

The P/B ratio is a good starting point in the valuation process. The following interpretation can be applied to different values.

A P/B ratio:

Below 1.0: Implies that the stock is trading below the book value and might have potential. It can also suggest poor financial management and issues within the firm.

Equal to 1.0: Implies that the firm’s market value is equal to the book value per share.

Above 1.0: Implies that investors are willing to pay more for the stock in comparison to the firm’s book value. A value significantly above 1.0 suggests that the firm has high-growth expectations.

In contrast, a value significantly below 1.0 is an indicator of value stocks. However, each company has different financial requirements, and an ideal P/B ratio differs for each company. A P/B ratio of 2.0 can be considered good for one firm but expensive for others.

Factors that affect the result

The following can affect a company’s P/B ratio:

1. Share price fluctuations: An increase or decrease in the share price will increase or decrease the ratio.

2. Total assets and liabilities: Fluctuations in either of the two will modify the ratio.

3. Profitability: A firm with higher profitability can support a higher price for the stock.

4. Industry: Industries with large assets such as the banking sector and other asset-heavy sectors are perfect to analyse using the P/B ratio.

5. Intangible assets: Patents, intellectual property, brand image are few examples of intangible assets that contribute to the value of the firms.

6. Risk: Higher levels of debt, assets impairment, or losses in earnings can modify the perceived valuation of a stock by investors.

Benefits and Practical Examples

The Price to Book Ratio Calculator offers a number of benefits:

1. Evaluate a company’s valuation: You can use the calculator to determine the P/B ratio of a company.

2. Compare stocks of companies in the same industry: You can compare two companies to identify the most attractive valuation.

3. Value stock picking: Identifies cheap stocks that are worth exploring further.

4. Compare the market value to the accounting value: Use the calculator to understand how the market values a company in comparison to the book value.

5. Shortlist stocks for valuation: You can utilise the ratio as a screening tool to shortlist stocks for further analysis.

To obtain a better valuation analysis it is advised to complement the P/B ratio with the Price to Earnings ratio (P/E), Return on Equity (ROE), Debt to Worth ratio, Earnings Growth, and Cash Flow.

Accuracy, Assumptions and Limitations

The Price to Book Calculator provides an accurate result based on the current share price and the book value per share. It is important that the inputs provided to the calculator are accurate.

Book value is based on the accounting information of the firm and can significantly differ from the true value of a company. Furthermore, the information provided in the financial statements of the company can also be out of date, and the share price of the company is constantly fluctuating throughout the trading day.

A negative book value will also prompt an inaccurate result. A negative book value is typically not interpreted to be useful in conventional P/B analysis. Similarly, a P/B ratio is not appropriate to use in cases where a significant portion of a company’s value derives from intangible assets. Hence, the calculator should be utilised as a screening tool for valuation.
