How to Write a Journal Entry

In the previous chapter, we looked at source documents and vouchers—the physical pieces of paper (like bills, receipts, and invoices) that prove a business transaction actually happened. But a business cannot run by just stuffing receipts into a drawer. Those pieces of paper need to be translated into the official language of accounting.

This translation happens in the Journal.

Think of the journal as the daily diary of a business. Every single time a financial event occurs, it is recorded here first, in chronological order (date by date), before it goes anywhere else in the accounting system. Because of this, the journal is universally known as the Book of Original Entry.

In this chapter, we are going to learn exactly how to write a journal entry. We will look at the standard five-column format, the specific grammar and punctuation used by accountants, how to record simple and complex transactions, and how to handle special cases like discounts. By the end of this, you will be able to look at any business transaction and write its journal entry flawlessly.

The Five-Column Format of a Journal

A standard accounting journal is divided into five specific columns. Every time you write a journal entry, you are filling out these five columns.

Here is what the columns are and what they do:

1. Date This column records the exact date the transaction took place. Accounting is strictly chronological. You cannot record a transaction from April 5th, then one from April 2nd, and then one from April 8th. They must flow in exact order. Usually, the year is written once at the top of the column, followed by the month and day for each entry.

2. Particulars This is the most important column. It is the wide middle section where the actual "story" of the transaction is written. Here, you will write the name of the account being debited, the name of the account being credited, and a short description of what happened (called the narration).

3. L.F. (Ledger Folio) "Folio" is just an old-fashioned word for "page number." The Ledger is the next book in the accounting cycle (which we will cover in the next chapter). The L.F. column is a cross-reference. When you eventually transfer (or "post") this journal entry into the Ledger, you will write the Ledger's page number in this L.F. column. Crucial note: When you are writing a journal entry for the first time, this column is always left blank. It only gets filled in later.

4. Debit (₹) This column holds the monetary amount that is being debited.

5. Credit (₹) This column holds the monetary amount that is being credited.

The Grammar of a Journal Entry

Writing a journal entry is like writing a sentence in a new language. There are strict rules about where words go, how they are indented, and what abbreviations are used.

Let’s look at the anatomy of a standard journal entry in the Particulars column.

Why do we write it this way?

You might wonder why we write "Dr." for the debit line, but we don't write "Cr." for the credit line. Instead, we use the word "To" and an indent.

This is purely a historical convention. Hundreds of years ago, accountants decided that indenting the credit line and starting it with "To" was enough of a visual cue to tell the reader, "This is the credit side." Writing "Cr." at the end was considered repetitive, so the practice was dropped. Today, if an account name is indented and starts with "To", every accountant in the world knows it is a credit.

Writing Simple Journal Entries

A simple journal entry is one that involves exactly two accounts: one account is debited, and one account is credited.

Let’s walk through a few practical examples. We will show how they look when written out in the standard format.

Example 1: Starting the Business

Transaction: On April 1, 2024, Ms. Priya started a business by bringing in ₹5,00,000 as cash capital.

Thought Process: Cash is coming into the business (Debit what comes in). Capital is the obligation to the owner (Credit the giver / increase in equity).

Date: April 1, 2024 Particulars: Cash A/c ... Dr. To Capital A/c (Being cash brought in by the owner as capital) L.F.: [Blank] Debit (₹): 5,00,000 Credit (₹): 5,00,000

Example 2: Purchasing Goods for Cash

Transaction: On April 4, 2024, the business purchased goods for cash worth ₹50,000.

Thought Process: Purchases are an expense (Debit all expenses). Cash is going out (Credit what goes out).

Date: April 4, 2024 Particulars: Purchases A/c ... Dr. To Cash A/c (Being goods purchased for cash) L.F.: [Blank] Debit (₹): 50,000 Credit (₹): 50,000

Example 3: Selling Goods on Credit

Transaction: On April 8, 2024, the business sold goods on credit to M/s Sharma Bros for ₹30,000.

Thought Process: M/s Sharma Bros is receiving the goods without paying yet, making them a debtor (Debit the receiver). Sales are an income (Credit all incomes).

Date: April 8, 2024 Particulars: M/s Sharma Bros A/c ... Dr. To Sales A/c (Being goods sold on credit to M/s Sharma Bros) L.F.: [Blank] Debit (₹): 30,000 Credit (₹): 30,000

Writing Compound Journal Entries

In business, things are rarely as simple as one debit and one credit. Often, a single transaction affects three, four, or even more accounts.

When a journal entry has more than one debit, or more than one credit, or both, it is called a Compound Journal Entry.

Compound entries are used to save time and space. If three different expenses are paid in cash on the exact same day, it is inefficient to write three separate journal entries. We combine them into one.

Example 4: Multiple Debits, One Credit

Transaction: On April 30, 2024, the business paid ₹10,000 for Rent and ₹25,000 for Salaries, both by cheque.

Thought Process: Rent and Salaries are both expenses (Debit all expenses). The payment is going out of the Bank (Credit the giver / decrease in asset). Instead of writing two entries, we combine them.

Date: April 30, 2024 Particulars: Rent A/c ... Dr. Salaries A/c ... Dr. To Bank A/c (Being rent and salaries paid by cheque) L.F.: [Blank] Debit (₹): 10,000 (for Rent) 25,000 (for Salaries) Credit (₹): 35,000 (for Bank)

Notice how the total of the debits (10,000 + 25,000) perfectly equals the total of the credit (35,000).

Example 5: One Debit, Multiple Credits (The Cash Discount)

Transaction: On May 5, 2024, the business owed ₹20,000 to a supplier, Mr. Gupta. The business paid Mr. Gupta ₹19,500 in cash in full settlement of his account.

Thought Process: We are settling a ₹20,000 debt for only ₹19,500. This means Mr. Gupta allowed us a discount of ₹500. Mr. Gupta is the receiver of the payment, so we debit his account to close it (Debit the receiver). Cash is going out (Credit what goes out). The discount we received is a gain for us (Credit all incomes and gains).

Date: May 5, 2024 Particulars: Mr. Gupta ... Dr. To Cash A/c To Discount Received A/c (Being cash paid to Mr. Gupta in full settlement and discount received) L.F.: [Blank] Debit (₹): 20,000 Credit (₹): 19,500 (for Cash) 500 (for Discount)

The Trap of Trade Discount vs. Cash Discount

This is one of the most frequently tested concepts in accounting exams. You must understand how discounts affect journal entries. There are two types of discounts, and they are treated completely differently in the journal.

1. Trade Discount

A trade discount is a bulk-buyer discount given by a manufacturer or wholesaler at the time of purchase. It is deducted directly from the catalog price or invoice price. The Rule: A trade discount is NEVER recorded in the journal. You simply subtract the discount amount in your head (or on a calculator) and write the journal entry for the net amount.

Example: Purchased goods with a list price of ₹1,00,000 at a 10% trade discount. Calculation: 10% of 1,00,000 = 10,000. Net price = ₹90,000. Journal Entry: You will debit Purchases and credit Cash/Creditor for ₹90,000. The ₹10,000 trade discount completely vanishes from the accounting records.

2. Cash Discount

A cash discount is an incentive given to encourage a debtor to pay their bill quickly (e.g., "Pay within 7 days and get 2% off"). The Rule: A cash discount MUST be recorded in the journal. It appears as a specific account called "Discount Allowed" (an expense, so it is debited) or "Discount Received" (a gain, so it is credited).

Special Journal Entries You Must Know

Certain transactions have specific conventions for how they are journalized. Here are the most common special cases you will encounter.

1. Goods Given as Charity or Free Samples

When a business gives away its own trading goods for charity or as free samples for advertising, it is not making a sale. Therefore, we cannot credit the Sales account. Instead, we are reducing the stock of goods we originally purchased.

Entry: Charity A/c (or Advertisement A/c) ... Dr. To Purchases A/c (Being goods distributed as free samples/charity) Note: We credit Purchases to reduce the expense of goods bought, since they weren't sold for profit.

2. Goods Taken by the Owner (Drawings)

If the owner takes cash from the till for personal use, we debit Drawings and credit Cash. But what if the owner takes a laptop from the store's inventory for their child? Just like charity, this reduces our purchased stock.

Entry: Drawings A/c ... Dr. To Purchases A/c (Being goods withdrawn by the owner for personal use)

3. Bad Debts

When a customer who owes you money goes bankrupt and cannot pay, the money is lost forever. This is a business loss called a "Bad Debt".

Entry: Bad Debts A/c ... Dr. To [Customer's Name] A/c (Being the amount due from customer written off as unrecoverable)

4. Bad Debts Recovered

Sometimes, a miracle happens. A customer whose account you wrote off as a Bad Debt two years ago suddenly walks in and hands you the cash. Because you already closed their personal account in the past, you do NOT credit their name. You credit a special gain account.

Entry: Cash A/c ... Dr. To Bad Debts Recovered A/c (Being cash received against a debt previously written off)

The Opening Entry

A business doesn't start from scratch every single year. At the end of a financial year (usually March 31st in India), a business has assets (like machinery, cash, and stock) and liabilities (like bank loans and creditors).

On the very first day of the new financial year (April 1st), the accountant must bring all these balances forward into the new year's books. This is done via a massive compound journal entry called the Opening Entry.

The Rule for Opening Entries:

• Debit all Asset accounts.
• Credit all Liability accounts.
• Credit the Capital account.

If the problem gives you the assets and liabilities but doesn't tell you the Capital amount, you must find it using the Accounting Equation: Capital = Assets - Liabilities.

Example of an Opening Entry: Date: April 1, 2024 Particulars: Cash A/c ... Dr. (₹50,000) Bank A/c ... Dr. (₹1,50,000) Stock A/c ... Dr. (₹2,00,000) Machinery A/c ... Dr. (₹3,00,000) To Creditors A/c (₹1,00,000) To Bank Loan A/c (₹2,00,000) To Capital A/c (₹4,00,000) [Calculated as Total Assets 7L - Total Liab 3L] (Being the balances brought forward from the previous year)

Casting and Carry Forwards

In the real world, a journal is a physical book with hundreds of pages. When an accountant reaches the bottom of page 1, they cannot just flip to page 2 and continue blindly. They must ensure that the mathematical accuracy (Debits = Credits) is maintained across pages.

This process is called Casting (totaling).

At the bottom of the page, the accountant draws a line and totals the Debit column and the Credit column. In the Particulars column, they write: Total c/f (which stands for Total Carried Forward).

At the very top of the next page, before writing any new transactions, they write those same totals into the new columns. In the Particulars column, they write: Total b/f (which stands for Total Brought Forward).

This ensures that if a mathematical error happens, the accountant knows exactly which page it occurred on, rather than having to check the entire year's book.

Quick Revision

• Book of Original Entry: The Journal is where transactions are recorded first, in chronological order.
• Five Columns: Date, Particulars, L.F. (Ledger Folio), Debit (₹), and Credit (₹).
• Formatting Rules: Debits are written flush left with "Dr." at the end. Credits are indented on the next line and start with "To".
• Narration: A short explanation in brackets starting with "Being", written below every entry.
• L.F. Column: Left blank while journalizing; filled later with the page number of the Ledger during posting.
• Compound Entry: An entry with more than one debit, more than one credit, or both.
• Trade vs. Cash Discount: Trade discounts are deducted directly and NEVER shown in the journal. Cash discounts are recorded as "Discount Allowed" or "Discount Received".
• Goods Given Away/Taken: If goods are used for charity, free samples, or owner's drawings, credit the Purchases A/c, not Sales.
• Opening Entry: The first entry of the year. Debit all assets, credit all liabilities, and credit Capital for the balancing figure.
