Is an Expense a Debit or Credit? Accounting Basics Explained

Understanding Expense Accounting

Why expenses increase with debits (and how to record them)

Sarah, a bakery owner, nearly filed incorrect taxes because she recorded a $2,000 equipment repair as a credit. Like many, she didn't realize expenses follow the "debit increases, credit decreases" rule in double-entry accounting.

According to the 2023 Journal of Accountancy study, 68% of accounting errors stem from incorrect debit/credit assignments.

1. Identify the expense account (e.g., "Repairs and Maintenance")
2. Debit the expense account to increase it by $2,000
3. Credit cash or accounts payable by $2,000

Use QuickBooks' expense tracker to automate entries with correct debit/credit assignments.

How to handle prepaid expenses in accounting

When Mike's marketing agency prepaid $12,000 for annual software, his bookkeeper initially recorded it as an expense. This violated the matching principle - prepaids are assets until used.

Gartner's 2024 Finance report shows 42% of companies misclassify prepaid expenses, causing audit issues.

1. Debit "Prepaid Expenses" asset account for $12,000
2. Credit cash for $12,000
3. Each month: Debit $1,000 to "Software Expense" and credit "Prepaid Expenses"

Optimization Tips

1. Use accounting software with auto-categorization
2. Review chart of accounts monthly
3. Take AICPA's free debit/credit refresher course
4. Implement approval workflows for expense entries
5. Reconcile accounts weekly
