The
price-to-book ratio, or
P/B ratio, is a
financial ratio used to compare a company's current market price to its
book value. It is also sometimes known as a Market-to-Book ratio. The calculation can be performed in two ways, but the result should be the same each way. In the first way, the company's
market capitalization can be divided by the company's total book value from its
balance sheet. The second way, using per-share values, is to divide the company's current share price by the book value per share (i.e. its book value divided by the number of outstanding shares).
