Shareholders' Equity = Share Capital + Retained Earnings – Treasury Stock. The share capital method is sometimes known as the investor's equation. The above formula sums the retained earnings of the business and the share capital and subtracts the treasury shares.
Shareholders' equity can be calculated by subtracting a company's total liabilities from its total assets, both of which are itemized on the company's balance sheet.
Shareholders' Equity = Total Assets – Total Liabilities Take the sum of all assets in the balance sheet and deduct the value of all liabilities.
Average shareholder equity takes the shareholder equity from a number of consecutive periods and averages them. Look at financial statements for two or more consecutive periods and find shareholder equity under "Liabilities and Equity." Add the figures together and divide by the number of statements.
The balance sheet provides the values needed in the equity equation: Total Equity = Total Assets - Total Liabilities. Where: Total assets are all that a business or a company owns.
