The Basic Accounting Equation Accounting data is represented by the following relationship among the assets, liabilities and owners’ equity of a business: Assets = Liabilities + Owners’ Equity The equation must be in balance after every recorded transaction in the system.

The Double Entry System Accounting information is based on the double entry system. An account is an arrangement of transactions affecting a given asset, liability or other element. Under this system, the two-sided effect of a transaction is recorded in the appropriate accounts. The recording is done by means of a “debit-credit” convention (set of rules) applying to all accounts.

The Double Entry System The system records the two-sided effect of transactions Transaction Two-sided effect Bought furniture for cash Decrease in one asset Increase in another asset Took a loan in cash Increase in an asset Increase in a liability

The Double Entry System Note that the accounting equation equality is maintained after recording each transaction.
