What is a Journal Entry? Accounting Explained

Michael Bush

In the world of accounting, a journal entry is a record of a business transaction that is made in the company’s general ledger. The general ledger is a collection of hundreds or thousands of accounts, each of which is related to a specific area of the business, such as sales, payroll, or office supplies. Journal entries are the first step in the accounting cycle and are used to record all business transactions and accounting events for a company.

Understanding the concept of journal entries and how they are used in accounting is crucial for anyone studying or working in the field of finance. This glossary entry will provide an in-depth and comprehensive explanation of journal entries, including their purpose, the different types, how they are recorded, and their importance in financial reporting.

Definition and Purpose of Journal Entries

A journal entry, in accounting, is a logging of transactions into accounting journal items. The journal entry can consist of several recordings, each of which is either a debit or a credit. The total of the debits must equal the total of the credits. It may seem complex, but it’s fundamental to the double-entry system that underpins the balance of the accounting equation.

The main purpose of journal entries is to keep a day-to-day, chronological record of a business and its transactions. Journal entries are the basis for all the changes that occur in a company’s financial statements. They provide a record of the company’s financial transactions for a given period, which can be a month, a quarter, or a year.

Components of a Journal Entry

A journal entry is composed of several important elements that make up the structure of this accounting tool. These components include the date of the transaction, the accounts affected by the transaction, the amount of the transaction, and a brief description of the transaction. Each of these components plays a crucial role in providing a clear and complete record of the company’s financial activities.

It’s important to note that each journal entry must always have at least one debit and one credit. This is a fundamental rule of the double-entry bookkeeping system, which states that for every financial transaction, amounts must be recorded in a minimum of two accounts. The total amount debited must always equal the total amount credited.

Types of Journal Entries

There are several types of journal entries that are used in accounting. These include simple journal entries, compound journal entries, adjusting journal entries, reversing journal entries, and closing journal entries. Each type of journal entry serves a different purpose and is used at different times during the accounting cycle.

Simple journal entries are those that involve only two accounts – one debited and one credited. Compound journal entries involve more than two accounts. Adjusting journal entries are used at the end of an accounting period to adjust the balances in the company’s general ledger accounts. Reversing journal entries are used at the beginning of a new accounting period to reverse the effect of certain adjusting journal entries made in the previous period. Finally, closing journal entries are used at the end of an accounting period to transfer the balances in temporary accounts to permanent accounts.

Recording of Journal Entries

The process of recording journal entries begins with identifying the accounts that are affected by a business transaction. Once these accounts have been identified, the next step is to determine whether each account should be debited or credited. This is done based on the rules of debit and credit, which state that assets and expenses increase with a debit and decrease with a credit, while liabilities, equity, and revenue increase with a credit and decrease with a debit.

After determining the debits and credits, the journal entry can be recorded in the general ledger. The date of the transaction is written first, followed by the account names, which are indented to the right for credits and to the left for debits. The amounts are then written in the debit and credit columns, followed by a brief description of the transaction. It’s important to note that the total debits must always equal the total credits in a journal entry.

Example of a Journal Entry

Let’s consider a simple example of a journal entry. Suppose a company purchases office supplies worth £500 on credit. In this case, the accounts affected are Office Supplies (an asset account) and Accounts Payable (a liability account). Since assets increase with a debit, the Office Supplies account is debited. On the other hand, liabilities increase with a credit, so the Accounts Payable account is credited. The journal entry would be recorded as follows:

Date: 1st January 2022
Debit: Office Supplies £500
Credit: Accounts Payable £500
Description: Purchased office supplies on credit

This journal entry shows that the company has increased its office supplies by £500 and has a liability to pay £500 to the supplier.

Importance of Journal Entries in Financial Reporting

Journal entries play a crucial role in financial reporting. They are the foundation of all financial statements, including the balance sheet, income statement, and cash flow statement. Without journal entries, it would be impossible to prepare these financial statements, which are essential for assessing a company’s financial health and making informed business decisions.

Journal entries provide a chronological record of all business transactions, making it easier to track the company’s financial activities. They also ensure the accuracy of financial statements by recording transactions in accordance with the rules of debit and credit. By providing a clear and complete record of all financial transactions, journal entries help to prevent errors and fraud in financial reporting.

Role of Journal Entries in Auditing

Journal entries also play a significant role in the auditing process. Auditors review a company’s journal entries to verify the accuracy of the financial statements and ensure that the company is complying with accounting standards and regulations. They look for any irregularities or discrepancies in the journal entries that could indicate errors or fraud.

Auditors also use journal entries to understand the company’s business transactions and assess the risk of material misstatement in the financial statements. By examining journal entries, auditors can gain insights into the company’s financial activities and identify any areas of concern that need further investigation.


In conclusion, journal entries are a fundamental part of accounting. They provide a detailed record of all business transactions, ensuring the accuracy and integrity of financial reporting. Understanding how to create and interpret journal entries is essential for anyone studying or working in the field of finance.

While the process of recording journal entries can seem complex, it becomes much easier with practice. By following the rules of debit and credit and understanding the different types of journal entries, you can effectively use this important accounting tool to keep track of a company’s financial activities and prepare accurate financial statements.
