Transactions, Accounting Equation & Double-Entry Basics

TAKEAWAYS:

• The accounting equation (Assets = Liabilities + Equity) must always balance after every transaction.
• Every transaction has two effects (dual-effect principle), recorded as a debit and a credit.
• Debits increase assets/expenses/dividends but decrease liabilities/equity/revenue.
• The accounting cycle starts with transactions, moves to journals, then ledgers, and finally financial statements.
• Real-world examples (e.g., eSewa deposits, Daraz sales) show how transactions impact businesses daily.
• Exam focus: Trace transactions through the accounting equation, identify debits/credits, and explain their impact on financial statements.

1. The Accounting Equation: The Foundation

The accounting equation is the backbone of financial accounting. It states: Assets = Liabilities + Owner’s Equity This equation must always balance. If one side changes, the other must adjust to keep it in equilibrium.

How Transactions Affect the Equation

Every business transaction impacts at least two accounts, altering the equation. For example:

• If a business buys inventory on credit, its Assets (Inventory) increase while Liabilities (Accounts Payable) increase—keeping the equation balanced.
• If a business pays rent, its Assets (Cash) decrease while Expenses (Rent Expense) increase, reducing equity.

Real-World Example: eSewa Transaction

When you deposit money into eSewa:

• Your bank account (Asset) decreases (cash leaves your wallet).
• eSewa’s liability (your eSewa balance) increases (they owe you that money).
• The accounting equation remains balanced: Your Cash (Asset) ↓ = eSewa Liability (Your Balance) ↑

2. The Dual-Effect Principle

Every transaction has two effects on the accounting equation. This is called the dual-effect principle. For example:

• Buying a laptop for cash:
  • Asset (Cash) decreases (credit).
  • Asset (Computer) increases (debit).
• Taking a bank loan:
  • Asset (Cash) increases (debit).
  • Liability (Loan Payable) increases (credit).

Why Dual Entry?

• Ensures accuracy (no single-entry errors).
• Helps track financial health (e.g., if assets grow but equity doesn’t, liabilities may be rising).
• Required by GAAP (Generally Accepted Accounting Principles).

3. Debits and Credits: The Language of Accounting

Debits (Dr) and credits (Cr) are not about increases or decreases—they depend on the account type:

Example: Opening a Business Bank Account

Suppose Mr. Thapa starts a Kathmandu Retail Shop and deposits ₹500,000 from personal savings into the business bank account.

Equation Check: Assets (₹500,000) = Liabilities (₹0) + Equity (₹500,000) ✅

4. Common Transactions and Their Effects

Let’s trace 5 real transactions for Mr. Thapa’s Kathmandu Retail Shop (in NPR):

Transaction 1: Purchasing Inventory on Credit

• Buys goods worth ₹200,000 from a supplier, to be paid later.

  Account	Dr (₹)	Cr (₹)	Explanation
  Inventory (Asset)	200,000		Asset increases (debit)
  Accounts Payable (Liability)		200,000	Liability increases (credit)

Equation Check: Assets (₹700,000) = Liabilities (₹200,000) + Equity (₹500,000) ✅

Transaction 2: Selling Goods for Cash

• Sells goods worth ₹150,000 for cash.

  Account	Dr (₹)	Cr (₹)	Explanation
  Cash (Asset)	150,000		Cash increases (debit)
  Sales Revenue		150,000	Revenue increases (credit)

Equation Check: Assets (₹850,000) = Liabilities (₹200,000) + Equity (₹650,000) ✅

Transaction 3: Paying Rent

• Pays ₹10,000 rent for the month.

  Account	Dr (₹)	Cr (₹)	Explanation
  Rent Expense	10,000		Expense increases (debit)
  Cash (Asset)		10,000	Cash decreases (credit)

Equation Check: Assets (₹840,000) = Liabilities (₹200,000) + Equity (₹630,000) ✅

Transaction 4: Taking a Bank Loan

• Borrows ₹300,000 from NMB Bank.

  Account	Dr (₹)	Cr (₹)	Explanation
  Bank Loan (Asset)	300,000		Asset increases (debit)
  Loan Payable (Liability)		300,000	Liability increases (credit)

Equation Check: Assets (₹1,140,000) = Liabilities (₹500,000) + Equity (₹630,000) ✅

Transaction 5: Withdrawing Cash for Personal Use

• Mr. Thapa withdraws ₹50,000 for personal expenses.

  Account	Dr (₹)	Cr (₹)	Explanation
  Drawing (Equity)	50,000		Equity decreases (debit)
  Cash (Asset)		50,000	Cash decreases (credit)

Equation Check: Assets (₹1,090,000) = Liabilities (₹500,000) + Equity (₹580,000) ✅

5. The Accounting Cycle: From Transactions to Financial Statements

The accounting cycle follows this flow:

Step-by-Step Breakdown

1. Transactions → Business activities (e.g., sales, purchases).
2. Journal Entries → Record transactions in the general journal (date, accounts, Dr/Cr).
3. Ledger Postings → Transfer journal entries to T-accounts (ledger).
4. Trial Balance → Summarize all ledger balances to check for errors.
5. Financial Statements → Prepare Income Statement and Balance Sheet.
6. Closing Entries → Reset temporary accounts (revenues, expenses) for the next period.

6. Real-World Applications

Example 1: Daraz Order Processing

When you place an order on Daraz:

• Daraz’s Assets (Inventory) decrease (credit).
• Daraz’s Revenue increases (credit).
• Your Liability (unpaid order) increases (debit to "Accounts Receivable" from Daraz’s perspective).

Example 2: Ncell Top-Up

When you buy a Ncell recharge card:

• Your Cash (Asset) decreases (credit).
• Ncell’s Liability (your prepaid balance) increases (debit).

Example 3: Bank Loan (NMB Bank)

When you take a ₹500,000 loan from NMB Bank:

• Your Asset (Cash) increases (debit).
• Your Liability (Loan Payable) increases (credit).
• The bank records the opposite:
  • Their Asset (Loan Receivable) increases (debit).
  • Their Equity (Profit) increases (credit).

9. Exam Tip

What Examiners Look For

✅ Correct Dr/Cr application – Always justify why an account is debited/credited. ✅ Balanced equation – Show how transactions keep Assets = Liabilities + Equity. ✅ Real-world connection – Relate to Nepali businesses (e.g., Daraz, banks, retail shops). ✅ Tracing transactions – Be able to start from a transaction and end with financial statements. ✅ Common errors – Avoid debiting liabilities or crediting assets.

High-Scoring Answers Include:

• T-accounts for ledger postings.
• Journal entries with proper explanations.
• Equation checks after each transaction.
• Real examples (e.g., "Like when Pathao pays drivers, their Cash decreases and Expense increases").
