Principles of Financial Accounting: The Accounting Equation and Double Entry - Expanded Accounting, Equation Assets Liabilities Common Stock Revenues Expenses Dividends

What It Is

The Expanded Accounting Equation is a fundamental concept in financial accounting that represents the relationship between a company's assets, liabilities, equity, revenues, expenses, and dividends. It is essential to understand this equation to prepare financial statements, such as the Balance Sheet and Income Statement. For example, if a company buys $10,000 of inventory on credit, the Expanded Accounting Equation would be affected as follows: Assets (Inventory) increase by $10,000, and Liabilities (Accounts Payable) also increase by $10,000.

Key Concepts & Formulas

• Assets: Resources owned or controlled by a company, such as cash, inventory, and property.
  • Example: A company has $5,000 in cash. Assets = $5,000
• Liabilities: Debts or obligations a company owes to others, such as accounts payable and loans payable.
  • Example: A company has $3,000 in accounts payable. Liabilities = $3,000
• Common Stock: The amount of money invested by shareholders in a company.
  • Example: A company has $10,000 in common stock. Common Stock = $10,000
• Revenues: Income earned by a company from its normal business operations.
  • Example: A company earns $20,000 in sales revenue. Revenues = $20,000
• Expenses: Costs incurred by a company to generate revenues.
  • Example: A company incurs $15,000 in cost of goods sold. Expenses = $15,000
• Dividends: Distributions of a company's earnings to its shareholders.
  • Example: A company pays $5,000 in dividends. Dividends = $5,000
• Gross Profit: The difference between revenues and cost of goods sold.
  • Formula: Gross Profit = Revenues - Cost of Goods Sold
  • Example: A company has $20,000 in revenues and $15,000 in cost of goods sold. Gross Profit = $5,000
• Net Income: The difference between revenues and total expenses.
  • Formula: Net Income = Revenues - Total Expenses
  • Example: A company has $20,000 in revenues and $25,000 in total expenses. Net Income = -$5,000

Common Mistakes

Mistake 1: Confusing Debits and Credits for Expense Accounts

• Correction: Debits increase assets, expenses, and drawings, while credits increase liabilities, equity, and revenues. Use the mnemonic "ADE" (Assets, Drawings, Expenses) to remember this rule.
• Example: A company incurs $5,000 in salaries expense. Dr. Salaries Expense $5,000 (not Cr.)

Mistake 2: Not Considering Normal Balances

• Correction: Assets, expenses, and dividends have normal debit balances, while liabilities, equity, and revenues have normal credit balances. Use the mnemonic "ALDER" (Assets, Liabilities, Drawings, Equity, Revenues) to remember this rule.
• Example: A company has $10,000 in cash. Assets = $10,000 (normal debit balance)

Mistake 3: Not Accounting for Accrued Expenses

• Correction: Accrued expenses are expenses that have been incurred but not yet paid. Use the formula Accrued Expenses = Expenses - Cash Paid to calculate accrued expenses.
• Example: A company incurs $5,000 in salaries expense but has not yet paid it. Accrued Expenses = $5,000

Exam Tips

Tip 1: Remember "ADE" for Debits

• Use the mnemonic "ADE" (Assets, Drawings, Expenses) to remember that debits increase assets, expenses, and drawings.

Tip 2: Watch for Reversing Normal Balances

• Be careful when reversing normal balances, as this can lead to incorrect journal entries. Use the mnemonic "ALDER" (Assets, Liabilities, Drawings, Equity, Revenues) to remember normal balances.

Tip 3: Consider Accrued Expenses

• Don't forget to account for accrued expenses, which are expenses that have been incurred but not yet paid.
