Understanding Journal Entries in Accounting

Journal entries are the foundation of accounting. Every financial transaction recorded in the books begins with a journal entry. The purpose of a journal entry is to apply the double-entry system, where every transaction affects at least two accounts — one debit and one credit.

The basic rule is simple:
Debit what comes in, expense, or asset increase.
Credit what goes out, income, or liability increase.

A standard journal entry includes the date, accounts debited and credited, amounts, and a short narration explaining the transaction.

Simple Journal Entries for Beginners

A simple journal entry involves only two accounts — one debit and one credit.

Example 1: Started business with cash $50,000

Cash is coming into the business, so it increases (Debit). Capital represents the owner’s investment (Credit).

Journal Entry:
Cash A/C Dr 50,000
To Capital A/C 50,000

Example 2: Purchased furniture for cash $5,000

Furniture is an asset increase (Debit). Cash decreases (Credit).

Furniture A/C Dr 5,000
To Cash A/C 5,000

Example 3: Paid rent $2,000

Rent is an expense (Debit). Cash decreases (Credit).

Rent A/C Dr 2,000
To Cash A/C 2,000

These are simple entries because only two accounts are affected.

Compound Journal Entries Explained

A compound journal entry involves more than two accounts.

Example 1: Purchased goods for $10,000, paid $4,000 cash and remaining on credit.

Goods (Purchases) increase (Debit 10,000). Cash decreases (Credit 4,000). Creditors increase (Credit 6,000).

Purchases A/C Dr 10,000
To Cash A/C 4,000
To Creditors A/C 6,000

Example 2: Paid salaries $5,000 and electricity bill $1,000 in cash.

Salaries expense and electricity expense both increase (Debit). Cash decreases (Credit).

Salaries A/C Dr 5,000
Electricity A/C Dr 1,000
To Cash A/C 6,000

Compound entries save time and record multiple effects in one transaction.

Understanding journal entries builds a strong accounting foundation. Once transactions are properly recorded in journals, they are posted to ledger accounts for further processing.
