Book value per share calculator
Shareholders' equity divided by shares, and the price-to-book ratio if you add a price. Type your own numbers; nothing is sent anywhere.
The formula
Book value per share = shareholders' equity ÷ shares; P/B = price ÷ book value per share
A worked example
Equity of $2,000,000,000 over 100,000,000 shares is $20.00 per share.
How to read it
Book value is what would remain on the balance sheet for owners if assets were valued as recorded and all liabilities were paid. It is an accounting figure, often far from what assets would fetch, and it understates companies whose value is in brands, software or people.
Educational, not investment advice. The result is arithmetic on the inputs you typed.

Questions
Which shares?
Use shares outstanding at the same date as the balance sheet. Company pages here divide by the fiscal year's weighted-average diluted shares and say so.
Can book value be negative?
Yes, after large losses or share repurchases. The ratio is then not meaningful.
