Estimated price-to-book ratio based on market price per share divided by book value per share.

Price-to-book ratio2.34x

Market price used$42.50

Book value used$18.20

InterpretationAbove book value

$42.50 divided by $18.20 in book value per share gives a price-to-book ratio near 2.34x.
P/B is often more useful when paired with earnings, return-on-equity, and tangible-book-value metrics instead of being used on its own.
Different industries can carry very different normal P/B ranges, so the comparison is usually most useful against similar businesses or periods.

This is a basic valuation estimate, not investment advice. Book value definitions and share-price context can change how meaningful the ratio is.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Translate share price into a book-value multiple

A multiple can be easier to compare than a stock price on its own when businesses have different per-share book values.

Compare peers with similar asset-heavy models

Price-to-book is often most useful when the businesses being compared have somewhat similar accounting and asset structures.

Use it with other per-share valuation tools

Price-to-book often makes more sense beside earnings, cash-flow, and tangible-book tools.

FAQ

Common questions

How is price-to-book calculated here?

The calculator divides market price per share by book value per share.

Why can price-to-book be more useful in some industries than others?

Because businesses with large tangible asset bases often make book-value comparisons more meaningful than businesses where intangible value drives more of the economics.

Why should I compare this with other metrics too?

Because book value alone does not tell you about profitability, cash generation, growth quality, or whether the assets are producing strong returns.
