What Is An Accounting Journal Entry?

Blog post

An accounting journal entry is more than just numbers – these numbers tell exactly which accounts were affected, by how much, and when. Journal entries are often referred to as the most important skills for accountants to learn because they determine the company’s financial statements. Based on how accurate those journal entries are, plans can be built out for possible business expansions and new hires and can answer questions about the company’s finances.

Understanding An Accounting Journal Entry

As the name suggests, journal entries were recorded in journals long before software and in that journal would be a record of all transactions in chronological order. To this day, every journal entry recorded is to be equal in debits and credits to keep the classic equation of Assets = Liabilities + Shareholders’ Equity in balance. For each journal entry, consider these elements:

  1. Which accounts are affected by the transaction?
  2. Does the affected account increase or decrease?
  3. How much is changed in each account?
  4. Are the overall debits and credits in balance?

What are Debits and Credits?

An accounting journal entry follows the previously mentioned equation:

Assets = Liabilities + Shareholders’ Equity

Debits will fall to the left side of the equation and Credits on the right. Debits add to expense and asset accounts and subtract from liability, revenue, and equity balances. On the other hand, Credits subtract from expense and asset balances, while adding to liability, revenue, and equity accounts. This concept of a transaction affecting two accounts, where one is debited, and the other is equally credited is known as double-entry bookkeeping.

The 6 Types of Journal Entry Format

All six types of journal entries have their unique purpose in accounting. Combined all together, these journal entries produce an accurate understanding of the company’s finances.

  1. Opening Entries: These entries carry over the closing balance from the previous accounting period as the opening balance for the current account period. So, in the case that $5,000 was the ending balance of the Cash account from the previous accounting period – the $5,000 balance will now be the opening entry for the current accounting period.
  1. Transfer Entries: These entries move or allocate an expense or income from one account to another. If JK Inc. wanted to transfer cash from its main account to a subsidiary, a transfer journal entry is required to make this happen.
  1. Closing Entries: These entries mark the end of an accounting period at a particular balance which is later transferred from a temporary to a permanent account. Temporary accounts can be the following: expense and loss accounts, revenue, income and gain accounts, income summary accounts, and dividend or withdrawal accounts.
  1. Adjusting Entries: Entries that record changes to accounts that do not otherwise account for in the journal, in compliance with the accrual method of accounting. Adjusting entries are entered at the end of the accounting period into the general ledger per matching and revenue recognition principles.
  1. Compound Entries: These entries affect more than two accounts where certain accounts may be credited or debited more than once. Thus, compound entries do not follow the traditional rule of a journal entry and often have an unequal number of debits and credits.
  1. Reversing Entries: Used to clarify bookkeeping, reversing entries are made at the start of a new accounting period to reverse adjusting entries made in the previous period.

Journal Entry Format and Elements

Below is the general format used to create an accounting journal entry:

  • At the very top is the Header – descriptor of the entry type and the date of entry to the journal.
  • A unique identifier – usually known as the Reference Number.
  • The account(s) and the amount(s) to be debited by the transaction and the date(s) these debits are made.
  • The account(s) and the amount(s) to be credited by the transaction and the date(s) these credits are made.
  • Description of the transaction.

An accounting journal entry tells the story of credits and debits moving through the books.
