You can figure out how much equity you have in your home by subtracting the amount you owe on all loans secured by your house from its current value, which you can determine with a formal appraisal or simply estimate using online tools.
How Is Equity Calculated? Equity is equal to total assets minus its total liabilities. These figures can all be found on a company's balance sheet for a company. For a homeowner, equity would be the value of the home less any outstanding mortgage debt or liens.
The formula for calculating the equity ratio is equal to shareholders' equity divided by the difference between total assets and intangible assets. The ratio is expressed in a percentage, so the resulting figure must then be multiplied by 100.
