Accounting Equation

ASSETS = LIABILITIES + EQUITY

Assets: What business owns (Cash, Land, Equipment, Inventory)
Liabilities: What business owes (Loans, Accounts Payable)
Equity: Owner's stake (Capital, Retained Earnings)

Example:
Assets: Rs. 100,000
Liabilities: Rs. 40,000
Equity: Rs. 60,000
Check: 100,000 = 40,000 + 60,000 ✓

Types of Accounts

• Assets: Debit increase, Credit decrease
• Liabilities: Credit increase, Debit decrease
• Equity: Credit increase, Debit decrease
• Revenue: Credit increase, Debit decrease
• Expenses: Debit increase, Credit decrease

Double Entry Principle

Every transaction has TWO effects - every debit has a corresponding credit. Total debits always equal total credits.

Rules of Debit and Credit

Practical Examples

Transaction 1: Owner deposits Rs. 50,000 cash
Analysis: Cash increases (asset), Capital increases (equity)
Entry: Debit Cash 50,000 / Credit Capital 50,000

Transaction 2: Buy equipment for Rs. 10,000 cash
Analysis: Equipment increases, Cash decreases
Entry: Debit Equipment 10,000 / Credit Cash 10,000

Transaction 3: Sell goods for Rs. 5,000 (cash received)
Analysis: Cash increases, Revenue increases
Entry: Debit Cash 5,000 / Credit Sales Revenue 5,000

What is a Journal?

Journal is the first formal record of business transactions. Transactions recorded in chronological order with explanation (narration).

Journal Entry Format

Date: [Transaction date]
[Account to be Debited]          Debit
    [Account to be Credited]            Credit
Narration: [Explanation]

Example:
2024-01-15
Cash                             50,000
    Capital                              50,000
Narration: Capital contributed by owner

Types of Journals

• General Journal: For all types of transactions
• Cash Book: For cash and bank transactions
• Sales Journal: For credit sales
• Purchase Journal: For credit purchases
• Sales Returns Journal: For return of goods
• Purchase Returns Journal: For return of purchased goods

Journal vs Ledger

What is a Ledger?

Ledger is the principal book where accounts are maintained. Transactions grouped by account type, balance calculated.

Ledger Format

                    Account: Cash
        _____________________________________________
Date     | Narration      | Debit  | Credit | Balance
2024-01-01| Capital      | 50,000 |        | 50,000 Dr
2024-01-05| Equipment    |        | 10,000 | 40,000 Dr
2024-01-10| Sales        | 5,000  |        | 45,000 Dr

Types of Ledger Accounts

• Personal Accounts: Debtors, creditors, banks
• Real Accounts: Assets (land, building, equipment)
• Nominal Accounts: Revenue, expenses, income

Posting Process

Transfer entries from Journal to Ledger accounts.

Step 1: Take entry from Journal
        Debit Cash 50,000 / Credit Capital 50,000

Step 2: Post to Cash account (Debit side)
Step 3: Post to Capital account (Credit side)

Step 4: Calculate balances after each posting

Debit and Credit Balance

• Debit Balance: Debits exceed credits
• Credit Balance: Credits exceed debits
• Assets normally have Debit Balance
• Liabilities normally have Credit Balance

What is Trial Balance?

Trial Balance lists all ledger account balances. Tests if total debits equal total credits.

• Posting error: Posted to wrong account

Errors NOT Detected

• Entry recorded twice
• Entry not recorded in journal
• Accounting principle error

What is Income Statement?

Income Statement (Profit & Loss Account) shows revenues and expenses for a period. Difference = Profit or Loss.

Expenses

• COGS: Cost directly related to production

Need for Adjustments

Trial Balance prepared from original entries. But some items need adjustment for accurate reporting (Matching Principle).

Common Adjustments

Depreciation Example

Equipment cost: 100,000
Useful life: 10 years
Annual Depreciation = 100,000 / 10 = 10,000

Adjustment Entry:
Debit Depreciation Expense 10,000
    Credit Accumulated Depreciation 10,000

In Balance Sheet:
Equipment              100,000
Less: Accumulated Dep. (10,000)
Net Equipment           90,000

Closing Entries

Transfer revenue and expense accounts to Profit & Loss account, then to Capital.

Step 1: Close Revenue accounts
Debit Sales 200,000
    Credit Income Summary 200,000

Step 2: Close Expense accounts
Debit Income Summary 120,000
    Credit Expenses 120,000

Step 3: Close Net Profit to Capital
Debit Income Summary 80,000
    Credit Capital 80,000

What is Cost Accounting?

Cost Accounting focuses on identifying, measuring, and controlling costs to assist management in decision-making.

Types of Costs

Cost Structure

Cost of Production:
  Raw Materials          50,000
  Direct Labor           20,000
  Manufacturing Overhead 10,000
Total Production Cost    80,000

Add: Opening Inventory    5,000
Less: Closing Inventory  (8,000)
Cost of Goods Sold       77,000

Gross Profit = Sales - COGS
             = 150,000 - 77,000 = 73,000

Break-Even Analysis

Point where Revenue = Total Cost (no profit, no loss)

Break-Even Point = Fixed Costs / Contribution Margin Ratio
Contribution Margin = Selling Price - Variable Cost per Unit

Financial Ratios

Liquidity Analysis

• Current Ratio: Ability to pay short-term debts (Ideal: 1.5-2.0)
• Quick Ratio: (Current Assets - Inventory) / Current Liabilities
• Cash Ratio: (Cash + Receivables) / Current Liabilities

Profitability Analysis

• Gross Profit Margin: Gross Profit / Sales
• Operating Margin: Operating Income / Sales
• Net Profit Margin: Net Income / Sales

Efficiency Ratios

• Asset Turnover: Sales / Total Assets
• Inventory Turnover: COGS / Average Inventory
• Receivables Turnover: Sales / Average Receivables
