Definition of the Accounting Equation

The accounting equation is the foundation of double-entry bookkeeping and represents the relationship between a company’s assets, liabilities, and equity. It ensures that a company's financial records remain balanced, meaning every transaction affects at least two accounts.

The basic formula of the accounting equation is:

Assets = Liabilities + Equity

This equation applies to all businesses in Canada, whether small startups or large corporations, and ensures compliance with International Financial Reporting Standards (IFRS) or Accounting Standards for Private Enterprises (ASPE).

For example, if a company in Vancouver purchases equipment worth $50,000 with a loan of $30,000, the remaining $20,000 is covered by the owner's equity, keeping the equation balanced.

Purpose of the Accounting Equation in Financial Management

The accounting equation is essential for the following:

1. Ensuring Financial Accuracy – Keeps balance sheets in check.
2. Guiding Bookkeeping and Transactions – Supports proper double-entry accounting.
3. Assessing Financial Health – Helps businesses evaluate their financial position.
4. Facilitating Tax and Audit Compliance – Ensures accurate financial reporting for Canada Revenue Agency (CRA) audits.
5. Aiding Business Decision-Making – Provides insights for financial planning and investments.

Components of the Accounting Equation

1. Assets

Assets are resources a business owns that provide economic value. These include:

• Current Assets – Cash, accounts receivable, and inventory.
• Fixed Assets – Property, plant, and equipment.
• Intangible Assets – Patents, trademarks, and goodwill.

2. Liabilities

Liabilities are obligations a company owes to creditors or suppliers. Examples include:

• Short-Term Liabilities – Accounts payable, wages payable, and short-term loans.
• Long-Term Liabilities – Mortgages, bonds payable, and deferred tax liabilities.

3. Equity

Equity represents the owner’s or shareholders' claim on the company after liabilities are paid. It includes:

• Common Stock and Retained Earnings – The owner's investment and accumulated profits.
• Dividends Paid – Distributions to shareholders.

Expanded Accounting Equation

For businesses with revenues and expenses, the formula expands to:

Assets = Liabilities + Owner’s Equity + (Revenue − Expenses)

This version accounts for business operations, ensuring that revenue increases assets while expenses reduce equity.

Examples of the Accounting Equation in Action

Example 1: Business Loan

A company borrows $100,000 from a bank.

• Assets increase by $100,000 (cash received).
• Liabilities increase by $100,000 (loan payable).
• The equation remains balanced:

Assets = Liabilities + Equity

100,000 = 100,000 + 0

Example 2: Purchasing Equipment with Cash

A company purchases equipment for $25,000 using cash.

• Assets decrease by $25,000 (cash).
• Assets increase by $25,000 (equipment).
• The equation remains unchanged.

Assets = Liabilities + Equity

Example 3: Earning Revenue

A business earns $50,000 in sales.

• Assets increase by $50,000 (cash or accounts receivable).
• Revenue increases equity by $50,000.

Assets = Liabilities + Equity + Revenue
