What is a journal entry?

A journal entry is fundamentally a record of a transaction in the accounting system that captures the accounts involved and their respective amounts. This is a crucial element of the double-entry accounting system, where each transaction affects at least two accounts—one account is debited, and another is credited. The journal entry includes specific details such as the date of the transaction, the accounts impacted, the amounts debited and credited, and a brief description of the transaction.

This detailed record allows businesses to maintain accurate financial records and ensures that the financial statements reflect all activities accurately. This tracking is essential not only for bookkeeping but also for financial analysis and reporting, which are vital for making informed business decisions. The clarity and organization provided by journal entries enable accountants to trace back any transaction, verify its accuracy, and ensure compliance with accounting standards.

Other options describe different aspects of accounting but do not define what a journal entry is. For instance, summarizing transactions for a fiscal year refers more to financial statements or ledgers rather than the individual entries themselves. A report on financial ratios relates to the analysis of financial performance, while an analysis of market trends deals with external business factors and strategic planning, neither of which directly describes a journal entry.
