Equity_(finance) =In finance, equity is ownership of assets that may have debts or other liabilities attached to them. Equity is measured for accounting purposes by subtracting liabilities from the value of an asset. For example, if someone owns a car worth $9,000 and owes $3,000 on the loan used to buy the car, then the difference of $6,000 is equity. Equity can apply to a single asset, such as a car or house, or to an entire business. A business that needs to start up or expand its operations can sell its equity in order to raise cash that does not have to be repaid on a set schedule.
When liabilities attached to an asset exceed its value, the difference is called a deficit and the asset is informally said to be 'underwater' or 'upside-down'. In government finance or other non-profit settings, equity is known as 'net position' or 'net assets'.
