The Accounting Equation

The accounting equation is the foundation of all accounting. It shows the relationship between what a business owns and how those assets are financed. The basic accounting equation is:

Assets = Liabilities + Owner’s Equity

Assets are things the business owns, such as cash, equipment, inventory, or buildings. Liabilities are what the business owes, such as loans or unpaid bills. Owner’s equity is the owner’s claim on the business after liabilities are paid.

Think of buying a house. The house is an asset. The mortgage loan is a liability. Your own money invested is equity. Together, they balance.

For example, if a business owns $50,000 in assets and owes $20,000 in liabilities, the owner’s equity is $30,000. The equation must always balance.

Every transaction affects the equation. If a business borrows money, assets increase and liabilities increase. If the owner invests cash, assets increase and equity increases. If expenses are paid, assets decrease and equity decreases.

This equation helps ensure accuracy. If the equation does not balance, there is an error. In simple terms, the accounting equation acts like a scale that must stay balanced at all times.
