Understanding Debits: Definition, Uses, and Examples

In accounting, a debit is an entry on the left side of an account ledger. It increases the balance of asset or expense accounts and decreases the balance of liability, equity, or revenue accounts. Debits are fundamental to the double-entry bookkeeping system, where every transaction involves at least one debit and one credit.

Key Points about Debits

  1. Associated with Increases: Increases asset and expense accounts.
  2. Associated with Decreases: Decreases liability, equity, and revenue accounts.
  3. Left Side Entry: Always recorded on the left side of a ledger.

How Does a Debit Work?

Double-Entry Bookkeeping System

The double-entry bookkeeping system requires that every financial transaction affects at least two accounts, ensuring the accounting equation (Assets = Liabilities + Equity) remains balanced.

Example: When a company purchases office supplies with cash, it records a debit in the Office Supplies account and a credit in the Cash account.

Accounting Equation:

Assets (Debit) = Liabilities + Equity (Credit)

Components of a Debit Entry

  1. Debit Side (Left Side): Records increases in assets and expenses.
  2. Credit Side (Right Side): Records decreases in assets and expenses or increases in liabilities, equity, and revenues.

Example of a Debit Entry

Office Supplies Purchase for $500

  1. Office Supplies Account: Debit $500
  2. Cash Account: Credit $500
