Shareholder's equity is a balance sheet metric that gauges the net value of all assets a company holds, less any liabilities. The metric is similar to book value as it gauges the net value of all of a company's "stuff". By definition, shareholder's equity differs from book value as the latter is supposed to remove intangible assets and goodwill from its calculation. However, in practice, most finance portals and publications include these intangible assets in the calculation of book value. Therefore, though technically the two are slightly different metrics, in practice, shareholder's equity is equivalent to book value.
