Double-entry bookkeeping is the foundation of modern accounting. It ensures that every financial transaction is recorded in at least two accounts, keeping the books balanced. This system is used by businesses of all sizes to maintain accurate financial records, identify errors, and generate reliable financial reports.
Here’s a step-by-step explanation of double-entry bookkeeping and how it works.
Double-entry bookkeeping means that for every financial transaction, there are two entries made:
1. A debit (Dr): An increase in one account.
2. A credit (Cr): A corresponding decrease in another account (or vice versa).
The total debits must always equal the total credits to keep the accounting equation in balance:
Assets = Liabilities + Equity
This system provides:
1. Accuracy: Ensures financial records are complete and balanced.
2. Error Detection: Makes it easier to spot mistakes because debits must equal credits.
3. Financial Insight: Helps generate accurate financial statements like the income statement and balance sheet.
Every transaction affects at least two accounts—one account is debited, and the other is credited. Let’s break this down with examples:
A business purchases $500 worth of office supplies using cash.
| Account | Debit (Dr) | Credit (Cr) |
|---------------------|-------------|-------------|
| Office Supplies | $500 | |
| Cash | | $500 |
The business borrows $10,000 from the bank.
| Account | Debit (Dr) | Credit (Cr) |
|---------------------|-------------|-------------|
| Cash | $10,000 | |
| Loan Payable | | $10,000 |
The business earns $1,200 in revenue from providing services, and the customer pays in cash.
| Account | Debit (Dr) | Credit (Cr) |
|---------------------|-------------|-------------|
| Cash | $1,200 | |
| Service Revenue | | $1,200 |
The business pays $1,000 in rent using cash.
| Account | Debit (Dr) | Credit (Cr) |
|---------------------|-------------|-------------|
| Rent Expense | $1,000 | |
| Cash | | $1,000 |
All transactions fall under five main account categories:
| Account | Debit (Dr) | Credit (Cr) |
|------------------|-------------|-------------|
| Cash | $10,000 | |
| Loan Payable | | $10,000 |
At the end of an accounting period, you create a trial balance to ensure total debits equal total credits.
| Account | Debit (Dr) | Credit (Cr) |
|------------------------|-------------|-------------|
| Cash | $11,200 | |
| Office Supplies | $500 | |
| Loan Payable | | $10,000 |
| Service Revenue | | $1,200 |
| Rent Expense | $1,000 | |
| Totals: | $12,700 | $12,700 |
If the totals don’t match, there’s an error in your entries that needs correction.
