The accounting equation shows that assets and liabilities of a company are equal. It is based on the dual concept that every transaction has two effects - a debit and a credit. Assets are possessions that result in economic resources flowing into the business, while liabilities are debts that result in outflows. Owners' equity represents the owners' claim on assets. To prepare an accounting equation, transactions are analyzed in terms of their impact on assets, liabilities, expenses and owners' equity, and the relevant accounts are adjusted. An example shows a business owner investing cash, increasing both the asset and owners' equity accounts by the same amount.
