Journal Entries Explained: How to Record Transactions
A journal entry is the record of a business transaction in the accounting system, showing the date, the accounts affected, and equal debit and credit amounts. It is the first place a transaction enters the books, which is why the journal is called the book of original entry. Every entry follows one rule: total debits must equal total credits.
Journal entries are the foundation of double-entry bookkeeping used under U.S. GAAP. They feed the general ledger, the trial balance, and ultimately the income statement and balance sheet. Get the entry right and everything downstream balances. Get it wrong and the error propagates through every report.
What is a journal entry?
A journal entry is a dated record showing which accounts increase and decrease when a transaction occurs, with debits on the left and credits on the right and both sides equal. Each entry names the accounts, the amounts, and usually a short description. At minimum an entry has one debit and one credit; the two sides must match to the cent.
Every business transaction touches at least two accounts. When a company pays $500 in rent, cash goes down and rent expense goes up. Recording both sides is the core of double-entry accounting, a method in continuous use since Luca Pacioli documented it in 1494.
The journal captures transactions in chronological order. Later, those entries are posted (copied) to the general ledger, where they are grouped by account. The journal answers “what happened and when”; the ledger answers “what is the balance of each account”.
The debit and credit rules
Debits increase assets and expenses and decrease liabilities, equity, and revenue. Credits do the opposite: they increase liabilities, equity, and revenue and decrease assets and expenses. Debit means the left side of an account and credit means the right side. The words carry no “good” or “bad” meaning; they are only directions.
Memorize the five account types and how each responds. The table below is the rule set every journal entry obeys.
| Account type | Normal balance | Increases with | Decreases with | Examples |
|---|---|---|---|---|
| Asset | Debit | Debit | Credit | Cash, accounts receivable, equipment, inventory |
| Expense | Debit | Debit | Credit | Rent, wages, utilities, cost of goods sold |
| Liability | Credit | Credit | Debit | Accounts payable, loans payable, accrued wages |
| Equity | Credit | Credit | Debit | Common stock, retained earnings, owner capital |
| Revenue | Credit | Credit | Debit | Sales, service revenue, interest income |
A common memory aid is DEAL and CLIP: Debits increase Expenses, Assets, and Losses; Credits increase Liabilities, Income, and equity (Plus). Whatever aid you use, the balance check is the same every time: add the debits, add the credits, confirm they are equal before you post.
How to record a journal entry: 6 steps
Recording a transaction means identifying the accounts, applying the debit and credit rules, and writing a balanced entry. The process is the same whether you use paper, a spreadsheet, or software like QuickBooks or NetSuite, though software often automates the posting step.
- Identify the transaction. Confirm an economic event occurred and gather the source document (invoice, receipt, bank record). No document, no entry.
- Determine the accounts affected. Every transaction hits at least two. Name them specifically (for example, “Cash” and “Sales Revenue,” not “money in”).
- Classify each account. Label each as asset, liability, equity, revenue, or expense.
- Apply the debit and credit rules. Decide whether each account increases or decreases, then use the table above to assign the debit or credit.
- Confirm debits equal credits. Sum both sides. If they differ, stop and find the mistake before posting.
- Record with a date and description. Write the date, list debits first (left), credits second (indented), and add a brief description below.
Journal entry format
The standard format lists the date, the debit account with its amount in the debit column, the credit account (indented) with its amount in the credit column, and a one-line description. Debits always appear above credits. This layout is the general journal format taught in every introductory accounting course and used in most accounting software behind the scenes.
A single entry looks like this:
- Date: March 5, 2026
- Debit: Equipment ….. $5,000
- Credit: ….. Cash $5,000
- Description: Purchased office equipment for cash
Worked examples: common journal entries
The table below shows how five routine transactions are recorded. Each entry balances, and each debit and credit follows the rules from the debit and credit table. These cover the transactions most small businesses record every week.
| # | Transaction | Account (Debit) | Debit | Account (Credit) | Credit |
|---|---|---|---|---|---|
| 1 | Owner invests $10,000 cash to start the business | Cash | $10,000 | Common Stock | $10,000 |
| 2 | Buy $2,000 of equipment on credit (pay later) | Equipment | $2,000 | Accounts Payable | $2,000 |
| 3 | Sell services for $1,500 cash | Cash | $1,500 | Service Revenue | $1,500 |
| 4 | Pay $600 monthly rent in cash | Rent Expense | $600 | Cash | $600 |
| 5 | Pay the $2,000 owed for the equipment | Accounts Payable | $2,000 | Cash | $2,000 |
Read entry 1: cash (an asset) rises, so it is debited; common stock (equity) rises, so it is credited. Read entry 4: rent expense rises, so it is debited; cash falls, so it is credited. In every row the debit column equals the credit column, which is the test that the entry is valid.
Simple vs compound journal entries
A simple journal entry has exactly one debit and one credit. A compound journal entry has three or more accounts, with multiple debits and/or multiple credits, and it is used when a single event affects several accounts at once. In both cases total debits must equal total credits.
Payroll is the classic compound entry. Suppose gross wages are $5,000, the employer withholds $1,000 for taxes, and pays $4,000 net. The entry debits Wages Expense $5,000, credits Taxes Payable $1,000, and credits Cash $4,000. One debit, two credits, and the sides balance at $5,000.
| Type | Accounts involved | Debits/credits | Typical use |
|---|---|---|---|
| Simple | Exactly 2 | One debit, one credit | Cash sale, rent payment, single-item purchase |
| Compound | 3 or more | Multiple debits and/or credits | Payroll, sales with sales tax, loan with fees |
Types of journal entries in the accounting cycle
Beyond routine transactions, several entry types appear at specific points in the accounting cycle. Knowing when each is used prevents misstated period-end financials. The main types are opening, standard, adjusting, closing, and reversing entries.
- Standard (transaction) entries record day-to-day activity as it happens.
- Adjusting entries are made at period end to record accruals, deferrals, and depreciation so revenue and expenses land in the correct period, as required by the accrual basis under GAAP.
- Closing entries zero out temporary accounts (revenue, expense, dividends) at year end and move the net result to retained earnings.
- Reversing entries are optional entries made on the first day of the new period to cancel certain prior-period accruals, which simplifies the next period’s recording.
- Opening entries carry forward the ending balances of permanent accounts to start a new set of books.
Which basis you use, cash or accrual, changes when some of these entries occur. Businesses with average annual gross receipts over the $30 million threshold (for the 2025 tax year, indexed) generally must use accrual accounting. For the details, see our guide on cash vs accrual accounting.
Why balanced entries matter downstream
Balanced entries keep the accounting equation intact: Assets equal Liabilities plus Equity. When every entry has equal debits and credits, the trial balance ties out, and the financial statements built from it are internally consistent. A single unbalanced entry throws off every report that follows.
The chain runs journal to ledger to trial balance to statements. Debits and credits from the journal flow to the income statement, where revenue and expenses meet, and to the balance sheet, where assets, liabilities, and equity settle. To see how those totals turn into reports, read how to read an income statement and how to read a balance sheet.
Frequently asked questions
What is the difference between a debit and a credit?
A debit is an entry on the left side of an account and a credit is an entry on the right side. Debits increase assets and expenses and decrease liabilities, equity, and revenue; credits do the reverse. Neither is inherently positive or negative. In every journal entry, total debits must equal total credits.
Do debits always have to equal credits?
Yes. In double-entry accounting, every journal entry must have total debits equal to total credits, down to the cent. This balance rule keeps the accounting equation (Assets equal Liabilities plus Equity) intact and lets the trial balance tie out. If the two sides differ, the entry has an error and should not be posted until it is corrected.
What is a compound journal entry?
A compound journal entry affects three or more accounts in a single entry, with multiple debits, multiple credits, or both. It is used when one event touches several accounts at once, such as payroll or a sale that includes sales tax. Despite the extra lines, total debits must still equal total credits.
What is the difference between a journal and a ledger?
The journal records transactions in date order and is the book of original entry. The ledger groups the same transactions by account to show each account’s running balance. Entries are first written in the journal, then posted (copied) to the ledger. The journal shows chronology; the ledger shows account balances.
What is an adjusting journal entry?
An adjusting journal entry is made at the end of an accounting period to record items not yet captured, such as accrued revenue, accrued expenses, prepaid amounts, and depreciation. Under the accrual basis required by GAAP, these entries place revenue and expenses in the correct period so the financial statements reflect the true position.
Can accounting software record journal entries automatically?
In many cases, yes. Software such as QuickBooks, Xero, and NetSuite often create entries automatically from actions like issuing an invoice or paying a bill, and they post to the ledger for you. Accountants still record manual journal entries for adjustments, corrections, and unusual transactions the software does not handle.
