Journal & Ledger – CMA Final Study Notes
(Accounting – Core Concepts – Chapter 3)
1. Simple Explanation
| Concept | What it is | Why it matters |
|---|---|---|
| Journal | The first place where every business transaction is recorded in chronological order, using a double‑entry format (debit = credit). | Keeps a complete, time‑ordered record of all activities; the base for all subsequent posting. |
| Ledger | A collection of T‑accounts – one account per ledger heading – where journal entries are posted to accumulate balances. | Provides balances for each account, which are needed to prepare the trial balance and financial statements. |
Flow of Information
Transaction → Journal Entry → Posting → Ledger → Trial Balance → Financial Statements
- Journal → records
- Ledger → organises and accumulates
- Trial Balance → verifies the ledger (debits = credits)
2. Key Points (What to Memorise)
| # | Topic | Key Take‑away | CMA Relevance |
|---|---|---|---|
| 1 | Double‑Entry | Every debit has an equal credit. | Foundation of the accounting equation. |
| 2 | Journal Voucher Types | Sales, Purchase, Cash Receipt, Cash Payment, Bank, etc. | Standardised voucher formats appear in exams. |
| 3 | Chart of Accounts | Numbered list of account titles used in the ledger. | Must be familiar for posting and coding. |
| 4 | Posting Rules | (a) Debit side of journal → left side of ledger; (b) Credit side → right side. | Critical for accurate ledger balances. |
| 5 | Ledger Classification | (i) General Ledger (GL) – master account list. (ii) Subsidiary Ledger – detailed account (e.g., AR, AP). |
CMAs must know when to reference each. |
| 6 | Trial Balance | Summarises all ledger balances; ensures debits = credits. | A key exam item – must spot errors quickly. |
| 7 | Post‑Closing | Closing entries transfer temporary balances to retained earnings. | Important for year‑end process. |
| 8 | Internal Controls | Segregation of duties, reconciliations, approvals. | Often part of exam questions on audit & risk. |
| 9 | Electronic Journals & Ledgers | Modern software (e.g., SAP, QuickBooks) uses similar principles. | CMA may ask about system controls. |
| 10 | Narratives & Supporting Documents | Each entry should have a clear description, reference, and supporting evidence. | Audit evidence requirement. |
Tip: In the CMA exam, you are expected to draft a journal entry and post it to the ledger under time pressure. Practice this until you can do it in ≤30 seconds.
3. Worked Example
Scenario
A company, ABC Ltd., on 15 Oct 2025 sells inventory on credit worth ₹ 150,000.
- Cost of goods sold (COGS) = ₹ 90,000
- Trade discount = 5% (deducted at the point of sale)
- Sales tax (GST) = 18% on the net sale amount
3.1 Journal Entry
| Date | Account | Debit | Credit |
|---|---|---|---|
| 15‑Oct‑25 | Accounts Receivable | 150,000 | |
| Sales | 142,500 | ||
| Sales Discount Allowed | 7,500 | ||
| GST Payable (CGST & SGST) | 25,650 | ||
| Cost of Goods Sold | 90,000 | ||
| Inventory | 90,000 |
Explanation
- Gross sales = ₹150,000
- Discount = 5% × 150,000 = ₹7,500 → net sales = 142,500
- GST = 18% × 142,500 = ₹25,650
- Debit AR to capture the receivable; credit Sales, Discount, GST Payable.
- Debit COGS and credit Inventory for the cost side.
3.2 Posting to the Ledger
| Account | Date | Debit | Credit | Balance |
|---|---|---|---|---|
| Accounts Receivable | 15‑Oct | 150,000 | 150,000 | |
| Sales | 15‑Oct | 142,500 | (‑142,500) | |
| Sales Discount Allowed | 15‑Oct | 7,500 | (‑7,500) | |
| GST Payable | 15‑Oct | 25,650 | (‑25,650) | |
| Cost of Goods Sold | 15‑Oct | 90,000 | 90,000 | |
| Inventory | 15‑Oct | 90,000 | (‑90,000) |
Note: Negative balances on credit‑side accounts (Sales, Discount, GST Payable, Inventory) represent credit balances.
