Net asset value of company/share. The Book Value Calculator takes total assets, total liabilities, shares outstanding and returns book value (net assets) plus book value per share. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Financial ratios are only useful in comparison: against last year, against a competitor, or against the benchmark for your industry. Take the figures from the same set of accounts, note whether they are yearly or monthly, and read each ratio alongside the others in its family. Use the worked example below to check the maths against your own figures.
How the Book Value Calculator works
Book value is what would be left for owners if every asset were sold at its balance-sheet value and every debt repaid. Compare the per-share figure with the share price to get the price-to-book ratio.
Worked example
With the example values (total assets of $2,000,000, total liabilities of $1,200,000, shares outstanding of 100000), the book value (net assets) is $800,000.00; book value per share $8.00. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.

Frequently Asked Questions
How is book value (net assets) calculated?
book value = total assets − total liabilities; per share = book value ÷ shares outstanding.
Which figures do I need?
Total assets, total liabilities, shares outstanding. Take them from the same period and the same set of accounts or reports so the ratio is consistent, and check the example values as a guide to the units expected.
What is a good value for this ratio?
Benchmarks differ by industry, size and business model, so compare with companies like yours and with your own history. A ratio moving in the wrong direction for several periods matters more than any single number.
