Why Journal Entries Matter
Ever wondered why accountants scribble those cryptic lines at the top of their books? Those lines are actually the story of every money‑move a business makes – and if you can read the story, the rest of accounting becomes a lot less scary.
💡 In Simple Words: A journal entry is like a diary entry for money. It records what happened, when it happened, and which accounts were affected, using a two‑column format called debit and credit.
What Is a Journal Entry?
A journal entry is the first official record of a financial transaction. Think of it as the first page of a comic strip: it shows the action (the transaction) and the characters (the accounts) before the story continues in the ledger.
Step‑by‑Step Guide to Pass a Journal Entry
Follow these six easy steps every time you face a new transaction.
Step 1 – Identify the Transaction
Read the problem carefully. Is the business receiving cash, buying something on credit, paying a bill, or earning revenue? Pinpoint the exact event.
Step 2 – Choose the Affected Accounts
Every transaction touches at least two accounts. One account gains value, another loses value. Common accounts include Cash, Bank, Sales, Purchases, Capital, and various expense or liability accounts.
Step 3 – Decide Debit and Credit
Remember the basic rule: Debit the thing that receives value, Credit the thing that gives value. An easy way to think of it is water flowing through pipes – the pipe that fills up (receives) is "debit," the pipe that empties (gives away) is "credit."
- Asset accounts (Cash, Equipment, etc.) increase on the debit side.
- Liability and Capital accounts increase on the credit side.
- Expense accounts increase on the debit side.
- Revenue accounts increase on the credit side.
Step 4 – Write Date & Reference Number
Start the entry with the date of the transaction. Add a short reference number (often the voucher or invoice number) so you can trace back to the original document.
Step 5 – Add a Narration
The narration is a one‑sentence description of the transaction. Keep it clear – "Cash received from sale of goods" works fine.
Step 6 – Enter the Amounts
Write the debit amount on the left column, then the credit amount on the right column. The two columns must always balance – the total debits should equal total credits.
Worked Example 1: Cash Sale of Goods
Transaction: On 5 May, XYZ Traders sold goods worth ₹12,000 cash.
Date Ref. No. Account Title Debit (₹) Credit (₹)
5‑May J1 Cash 12,000
Sales Revenue 12,000
(Cash received for goods sold)
Worked Example 2: Credit Purchase of Supplies
Transaction: On 12 May, the same firm bought office supplies on credit for ₹3,500.
Date Ref. No. Account Title Debit (₹) Credit (₹)
12‑May J2 Office Supplies 3,500
Creditors 3,500
(Supplies bought on credit)
