Accounting Transactions & Equation: Rules, Effects & Real-World Applications

TAKEAWAYS

• Every transaction must satisfy the accounting equation (Assets = Liabilities + Equity) and follow the dual-aspect concept (every debit has a credit).
• Transactions are recorded in journal entries (date, accounts, amounts, narration) before being posted to ledger accounts (t-accounts).
• The accounting equation expands to Assets = Liabilities + Owner’s Equity + Revenue – Expenses – Drawings when transactions occur.
• Real-world applications: eSewa uses the accounting equation to track user deposits (Assets) and service fees (Revenue); Daraz’s inventory system records purchases (Assets ↑, Liabilities ↑) and sales (Assets ↓, Revenue ↑).
• Common errors: Omitting narration, mismatched debits/credits, or ignoring trade discounts can distort financial statements.
• Exam focus: Trace transactions through the accounting cycle (journal → ledger → trial balance) and explain their impact on the equation.

1. The Accounting Equation: The Foundation of Every Transaction

The accounting equation is the mathematical backbone of double-entry accounting. It states: Assets = Liabilities + Owner’s Equity When transactions occur, this equation expands to reflect changes in revenue, expenses, and drawings: Assets = Liabilities + Equity + Revenue – Expenses – Drawings

How Transactions Affect the Equation

Every transaction impacts at least two accounts (dual-aspect concept). Use this table to predict effects:

Worked Example: Kathmandu Retail Shop (NPR)

Transaction: Mr. Bista started a retail shop in Kathmandu with cash Rs 500,000 and inventory worth Rs 300,000. He borrowed Rs 200,000 from a bank for working capital. Step 1: Write the initial accounting equation.

• Assets: Cash (500,000) + Inventory (300,000) = 800,000
• Liabilities: Bank Loan (200,000)
• Equity: Capital (500,000) + Inventory (300,000) = 800,000 Equation: 800,000 (A) = 200,000 (L) + 600,000 (E)

Step 2: Record transactions in journal entries (see next section).

2. Recording Transactions: Journal Entries and the Dual-Entry System

Every transaction is first recorded in a journal (chronological order) before being posted to ledger accounts. The rules of debit/credit are:

• Debit (Dr): Left side of an account.
  • Increases: Assets, Expenses, Drawings.
  • Decreases: Liabilities, Equity, Revenue.
• Credit (Cr): Right side of an account.
  • Increases: Liabilities, Equity, Revenue.
  • Decreases: Assets, Expenses, Drawings.

Journal Entry Format

| Date       | Particulars (Accounts)       | L.F. | Dr (Rs) | Cr (Rs) | Narration                          |
|------------|------------------------------|------|---------|---------|-------------------------------------|
| 2079-04-01 | Cash A/c                     |      | 500,000 |         | Capital introduced by Mr. Bista     |
|            | Capital A/c                  |      |         | 500,000 |                                     |
| 2079-04-01 | Inventory A/c                |      | 300,000 |         | Goods purchased for resale          |
|            | Capital A/c                  |      |         | 300,000 |                                     |
| 2079-04-01 | Bank Loan A/c                |      |         | 200,000 | Loan taken from NMB Bank            |
|            | Cash A/c                     |      | 200,000 |         |                                     |

Worked Example: Biraj Marga’s Purchase (Exam-Style)

Transaction: Biraj Marga purchased 500 chairs @ Rs 800 each and 20 sofa sets @ Rs 10,000 each on credit from SB Furniture. Trade discount: 5% on both. Step 1: Calculate total cost and discount.

• Chairs: 500 × 800 = 400,000
• Sofa sets: 20 × 10,000 = 200,000
• Total: 400,000 + 200,000 = 600,000
• Discount: 5% of 600,000 = 30,000
• Net amount: 600,000 – 30,000 = 570,000

Step 2: Journal entry.

| Date       | Particulars                  | L.F. | Dr (Rs) | Cr (Rs) | Narration                          |
|------------|------------------------------|------|---------|---------|-------------------------------------|
| 2079-04-10 | Furniture A/c                |      | 570,000 |         | Purchased chairs & sofa sets        |
|            | Discount A/c                 |      | 30,000  |         | Trade discount received             |
|            | SB Furniture A/c             |      |         | 600,000 |                                     |

Impact on Accounting Equation:

• Assets (Furniture): ↑ 570,000
• Liabilities (SB Furniture): ↑ 600,000
• Discount (Contra-equity): ↑ 30,000 (reduces cost) New Equation: A = L + E → 570,000 (Furniture) + 500,000 (Cash) = 600,000 (L) + 470,000 (E).

3. Posting to Ledger Accounts (T-Accounts)

Journal entries are transferred to ledger accounts (t-accounts) to track balances. Each account has:

• Left side (Dr): Debits.
• Right side (Cr): Credits.
• Balance: Difference between Dr and Cr.

T-Account Example: Cash Account for Mr. Bista

| Cash A/c                          |
|-----------------------------------|
| **Date** | **Particulars** | **Dr (Rs)** | **Cr (Rs)** |
| 2079-04-01 | Capital A/c       | 500,000     |             |
| 2079-04-01 | Bank Loan A/c    | 200,000     |             |
| **Total Dr** | **700,000**       |             |             |
| **Balance (Dr)** | **700,000**       |             |             |

Worked Example: Pathao’s Ride Transactions

Scenario: Pathao records a driver’s earnings and expenses.

1. Driver earns Rs 15,000 (revenue):

   | Cash A/c       |       | Driver Revenue A/c |
   |----------------|-------|-------------------|
   |                | 15,000|                   |
   

   Equation: A ↑ (Cash), R ↑ (Revenue).

2. Pathao pays Rs 5,000 for bike maintenance (expense):

   | Maintenance Expense A/c |       | Cash A/c       |
   |-------------------------|-------|----------------|
   | 5,000                   |       |                |
   

   Equation: A ↓ (Cash), X ↑ (Expense).

4. The Accounting Cycle: From Transactions to Financial Statements

Transactions follow this cycle:

Key Steps Explained

1. Journal: Chronological record of transactions.
2. Ledger: Individual accounts with Dr/Cr entries.
3. Trial Balance: List of all ledger balances to check arithmetic accuracy.
4. Adjusting Entries: Record accruals/deferrals (e.g., unpaid salaries, prepaid rent).
5. Financial Statements: Income Statement (Revenue – Expenses) and Balance Sheet (Assets = Liabilities + Equity).

6. Real-World Applications of Transactions and the Accounting Equation

Example 1: eSewa (Digital Payments)

• Transaction: User deposits Rs 10,000 into eSewa wallet.
  • Journal Entry:

    | Dr: Cash A/c (Bank)       | 10,000 |
    | Cr: User Deposit Liability | 10,000 |
    

  • Equation: A (Cash) ↑, L (User Deposits) ↑.
• Why it matters: eSewa must track deposits as liabilities until users withdraw funds.

Example 2: Daraz (E-Commerce Inventory)

• Transaction: Daraz purchases 100 laptops @ Rs 50,000 each on credit.
  • Journal Entry:

    | Dr: Inventory A/c         | 5,000,000 |
    | Cr: Supplier A/c          | 5,000,000 |
    

  • Equation: A (Inventory) ↑, L (Supplier) ↑.
• Real impact: Inventory is an asset until sold; unsold stock appears in the balance sheet.

Example 3: Ncell (Telecom Revenue Recognition)

• Transaction: Ncell sells a Rs 2,000 SIM card on credit.
  • Journal Entry:

    | Dr: Accounts Receivable   | 2,000 |
    | Cr: Revenue               | 2,000 |
    

  • Equation: L (Receivable) ↑, R ↑.
• Adjustment: If the customer pays late, Ncell records:

  | Dr: Cash                   | 2,000 |
  | Cr: Accounts Receivable   | 2,000 |
  

  Equation: A (Cash) ↑, L (Receivable) ↓.

Example 4: Bank Loan (NMB Bank)

• Transaction: A business takes a Rs 500,000 loan.
  • Journal Entry:

    | Dr: Cash                   | 500,000 |
    | Cr: Bank Loan              | 500,000 |
    

  • Equation: A (Cash) ↑, L (Loan) ↑.
• Interest payment: Monthly interest of Rs 5,000:

  | Dr: Interest Expense       | 5,000 |
  | Cr: Cash                   | 5,000 |
  

  Equation: X ↑, A (Cash) ↓.

8. Exam Tip: How to Score Full Marks

1. Show the accounting equation for every transaction. Examiners love seeing:
   • Before transaction: A = L + E
   • After transaction: A ± X = L ± Y + E ± Z
2. Use proper formats:
   • Journal entries: Date, accounts, Dr/Cr, narration.
   • T-accounts: Clear Dr/Cr sides with totals.
3. Trace transactions through the cycle:
   • Start with journal → ledger → trial balance.
4. Highlight real-world ties:
   • Relate to eSewa (liabilities), Daraz (inventory), or banks (loans).
5. Watch for hidden details:
   • Trade discounts, outstanding amounts, or contra-entries (e.g., discount received).
6. Practice numericals:
   • Solve past exam questions on purchases/sales with discounts and credit terms.

Past Exam Question Solved: Q: Goods costing Rs 60,000 were sold at 10% profit. Rent paid Rs 30,000, outstanding rent Rs 6,000. Show the accounting equation. Solution:

1. Sale at profit:
   • Cost of goods sold (COGS) = 60,000
   • Profit = 10% of 60,000 = 6,000
   • Revenue = 60,000 + 6,000 = 66,000
   • Journal:

     | Dr: Cash/Bank A/c       | 66,000 |
     | Cr: Revenue             | 66,000 |
     | Dr: COGS A/c            | 60,000 |
     | Cr: Inventory A/c       | 60,000 |
     

2. Rent expense:
   • Paid rent: 30,000 (expense)
   • Outstanding rent: 6,000 (accrued expense)
   • Total expense: 36,000
   • Journal:

     | Dr: Rent Expense A/c    | 30,000 |
     | Cr: Cash                | 30,000 |
     | Dr: Rent Expense A/c    | 6,000  |
     | Cr: Rent Payable A/c    | 6,000  |
     

3. Accounting Equation:
   • Before transactions: A = L + E
   • After sale:
     • A (Cash) ↑ 66,000
     • A (Inventory) ↓ 60,000
     • R ↑ 66,000
     • New Equation: (A + 6,000) = L + (E + 66,000 – 60,000)
   • After rent:
     • X ↑ 36,000
     • L (Rent Payable) ↑ 6,000
     • Final Equation: A = L + (E + 66,000 – 60,000 – 36,000) + 6,000
