The Basic Accounting Equation
The fundamental accounting equation forms the basis of the double-entry system of accounting. It ensures that every transaction keeps the balance intact, expressing that: Assets = Liabilities + Owner’s Equity.
ASSETS
Resources owned by the business
LIABILITIES
Debts owed to creditors
OWNER'S EQUITY
Owner’s claim on total assets
Key Points to Remember
- The accounting equation must always remain balanced.
- Assets represent what the business owns or controls.
- Liabilities represent what the business owes to outsiders.
- Owner’s Equity represents the owner’s investment and accumulated profits.
- Every transaction affects at least two accounts — maintaining equality.
Types of Assets
- ✓ Current Assets (Cash, Inventory, Debtors)
- ✓ Fixed Assets (Land, Building, Machinery)
- ✓ Intangible Assets (Patents, Goodwill)
- ✓ Investments and Prepaid Expenses
Types of Liabilities
- ✓ Current Liabilities (Creditors, Bills Payable)
- ✓ Long-term Liabilities (Loans, Bonds Payable)
- ✓ Contingent Liabilities (Possible Obligations)
- ✓ Accrued & Deferred Liabilities
Owner's Equity Components
- ✓ Capital Introduced by Owner
- ✓ Retained Earnings / Reserves
- ✓ Revenues Increase Equity
- ✓ Expenses & Drawings Decrease Equity
Classification of Accounts
Asset Account
Represents all valuable resources owned by the business. Rule: Debit increases, Credit decreases.
Liability Account
Represents obligations owed to outsiders. Rule: Debit decreases, Credit increases.
Capital Account
Shows the owner's claim on the business. Rule: Debit decreases, Credit increases.
Revenue / Income Account
Represents income earned through operations or investments. Rule: Debit decreases, Credit increases.
Expense / Loss Account
Records costs incurred and losses suffered by the business. Rule: Debit increases, Credit decreases.
Golden Rules of Accounting
- For Personal Accounts: Debit the receiver, Credit the giver.
- For Real Accounts: Debit what comes in, Credit what goes out.
- For Nominal Accounts: Debit all expenses and losses, Credit all incomes and gains.

Revenue Impact
Increases both assets and owner's equity. Examples: Sales, Service Income, Interest Earned
Expense Impact
Decreases assets and owner's equity. Examples: Rent, Salaries, Utilities, Supplies
Drawings Impact
Reduces both assets and owner's equity. Personal withdrawals by the owner
Net Income
Revenue - Expenses = Net Income (adds to owner's equity if positive)
Closing Process
Revenue and expense accounts are closed to owner's equity at period end

How to Read This Table
After each transaction, observe how account balances change while the equation Assets = Liabilities + Capital always remains balanced. Green text shows increases, red text shows decreases.
Key Observations
- Cash Transactions: When buying assets for cash (T2, T3), cash decreases but another asset increases — total assets remain same.
- Credit Purchases: Buying on credit (T4, T10) increases both assets and liabilities equally.
- Expenses: Paying expenses (T5, T9) reduces both cash and capital.
- Sales with Profit: Selling goods at profit (T6) increases cash more than goods decrease, profit increases capital.
- Paying Liabilities: Paying creditors (T7) decreases both cash and liabilities.
- Drawings: Owner withdrawals (T8) reduce both assets and capital.
