📚 CMA Final – Accounting
Journal & Ledger
Objective – Master the mechanics of double‑entry bookkeeping, the flow from the journal to the ledger, and the subtleties that appear in exam‑style problems.
1️⃣ What Are Journal & Ledger?
| Journal | Ledger | |
|---|---|---|
| Definition | A chronological book of original entry where every transaction is first recorded. | A book that aggregates all accounts (debit & credit side) and is used for posting from the journal. |
| Function | Keep a record of what happened and when. | Organize the totals for each account to compute balances. |
| Structure | T‑account format (or modern spreadsheet). | T‑accounts for each account (debit column left, credit column right). |
| Typical Entries | General Journal (for all non‑special cases). | General Ledger (every account). |
| Key Rule | Double entry: each transaction has at least one debit and one credit of equal amount. | Accounts must balance: Debit total = Credit total for every account. |
| Exam Relevance | Accurate journal entries are the source of truth. Mistakes here propagate. | Balances in ledger are used for Trial Balance, financial statements, and audits. |
2️⃣ The Double‑Entry System – “The Backbone”
2.1 Accounting Equation
[ \boxed{ \text{Assets} = \text{Liabilities} + \text{Equity}} ]
Every entry must keep this equation in balance.
2.2 The Debit–Credit Rule
| Account Type | Debit Effect | Credit Effect |
|---|---|---|
| Asset | Increase | Decrease |
| Liability | Decrease | Increase |
| Equity (Capital) | Decrease | Increase |
| Expense | Increase | Decrease |
| Revenue | Decrease | Increase |
Rule of Thumb: Debit = Credit for every transaction.
2.3 Journal Entry Syntax
Date | Account | Debit | Credit | Narration
- Narration explains why the entry was made (non‑numeric).
- If there are multiple debits/credits, list them on separate lines (same date) or in a single line separated by commas.
3️⃣ Types of Journals
| Journal | When to Use | Typical Example |
|---|---|---|
| General Journal (GJ) | All transactions not covered by special journals. | Payment for office supplies. |
| Sales Journal | All credit sales. | Sale of goods on account. |
| Purchase Journal | All credit purchases. | Buying inventory on credit. |
| Cash Receipts Journal | All cash inflows. | Cash receipts from customers. |
| Cash Disbursements Journal | All cash outflows. | Cash paid for rent. |
| Payroll Journal | All payroll transactions. | Salary paid to employees. |
Tip – In the exam, if a transaction can fit a special journal, you must use it; otherwise, use GJ.
4️⃣ The Ledger – Organizing by Account
4.1 Posting Process (Chronological Flow)
- Record the transaction in the journal.
- Post the debit side of the journal entry to debit side of the corresponding account in the ledger.
- Post the credit side of the journal entry to credit side of the corresponding account in the ledger.
- Calculate running balance after each posting (debit balance or credit balance).
- Cross‑check that the sum of all debit balances = sum of all credit balances (Trial Balance).
Common Mistake – Omission of posting (leaving a column blank) will leave the ledger unbalanced.
4.2 T‑Account Example
| Cash | |
|---|---|
| Debit | Credit |
| 10,000 (Cash received) | |
| 2,000 (Cash paid) | |
| 8,000 (Balance) |
Balance Calculation:
Debit side total = 10,000
Credit side total = 2,000
Balance = 10,000 – 2,000 = 8,000 (Debit balance)
5️⃣ Trial Balance – The Immediate Checkpoint
- Formula:
[ \boxed{ \sum \text{Debit balances} = \sum \text{Credit balances} } ] - Usage: Detects posting errors that affect the equality of totals.
- Limitations: Errors of omission, transposition, or errors that balance each other in the ledger will not be caught.
Exam Trick – If the Trial Balance is balanced, still check for other errors (e.g., wrong nature of account, wrong account number).
