Concept 1

The Accounting Equation

The accounting equation is the foundation of all financial reporting:

Assets = Liabilities + Equity

The equation must always remain in balance. Every financial transaction affects at least two accounts, ensuring accuracy and internal consistency throughout the accounting system.

Examples

Concept 2

Understanding Account Types

Students learn how each major account category operates within the accounting equation.

Assets

Resources owned by the business such as cash, inventory, accounts receivable, equipment, and prepaid expenses.

Liabilities

Obligations owed to others such as accounts payable, loans, credit cards, and payroll liabilities.

Equity

Owner’s claim on the business, including contributed capital, retained earnings, and owner withdrawals/dividends.

Concept 3

The Chart of Accounts (COA)

The Chart of Accounts is a structured list of all accounts used by the business. It organizes financial data into standardized categories and numbering.

Typical Structure

Students learn how QuickBooks, Xero, and other software implement the COA behind the scenes.

Concept 4

The Double-Entry System

The double-entry system ensures that every transaction has two equal sides:

Total debits must always equal total credits.

This maintains the accounting equation and prevents imbalance or misstatement of financial records.

Concept 5

Debits and Credits

The “Golden Rules” of debit and credit behavior:

Account Type Debit ↑ Credit ↑
Assets Increase Decrease
Liabilities Decrease Increase
Equity Decrease Increase
Revenue Decrease Increase
Expenses Increase Decrease

This week teaches students to apply these rules to every journal entry.
