Accounting Equation Definition

The accounting equation, also known as balance sheet equation, shows the relationship between assets, liabilities, and equity.

Accounting equation is the foundation of double-entry accounting system and a basic principle of accounting that states a company’s total assets are equal to the sum of all total liabilities and equity.

Based on the accounting equation, the total dollar amounts of the two sides are always equal. For example, an increase in an asset account can be matched by an equal increase to a related liability or equity account. 

Every transaction affects at least two accounts in a way that keeps the accounting equation in balance.

Accounting Equation Components

The accounting equation is made up of three main components and they are: Assets, liabilities, and Equity.

A company owns assets that may be partially owned by owners (stockholders) and/or partially owned by outsiders (debtors).

Whenever a company purchases an asset, there are two ways to pay for it: either it pays for the asset with equity (its own money) or through liability (other people money)

  • Assets (what it owns): Assets are any item of value or resources that a company owns or controls such as cash, accounts receivable, inventory, prepaid insurance, investments, land, buildings, equipment, and goodwill.
  • Liabilities (what it owes to others): Liabilities are debts or obligations that a company owes to others such as accounts payable, notes payable, salaries and wages payable, interest payable, and income tax payable.
  • Equity (the difference between assets and liabilities): Represents the residual interest or the leftover when a company sells all its assets and pays the liabilities. How much owners have invested into the company along with any retained profit or losses.

The basic format for the accounting equation is:

Assests = Liabilities + Equity
