The Double-Entry System

Master the rules of debit and credit at the heart of the double-entry system.

The double-entry system is the foundation of modern accounting: every transaction has two equal effects — one debit and one credit. It is guided by the accounting equation: Assets = Liabilities + Owner's Equity.

Key idea

Assets & expenses increase on the debit; liabilities, equity & income increase on the credit. Drawings reduce capital — so drawings are debited.

Example transaction

The business buys goods for RM1,000 in cash:

  • Debit Purchases RM1,000 (an expense increases).
  • Credit Cash RM1,000 (an asset decreases).

Example

The owner brings in RM20,000 cash as capital: debit Cash RM20,000 (asset up), credit Capital RM20,000 (equity up).

More examples

Paying rent of RM800 in cash: debit Rent (expense up), credit Cash (asset down). Buying furniture worth RM3,000 on credit from Indah Furniture: debit Furniture (asset up), credit Indah Furniture (liability up). In each case one account is debited and another credited by the same amount, keeping the accounting equation in balance.

Remember

For every transaction, total debits MUST equal total credits. This keeps the accounting equation in balance.
