Introduction
Understanding the difference between debits and credits is fundamental to running a successful business. Whether you’re a startup entrepreneur or managing an established company, mastering these accounting basics will help you make informed financial decisions and maintain accurate books.
Many business owners find debit and credit confusing at first – and that’s completely normal. The accounting definition of these terms differs significantly from how we use them in everyday banking. In this comprehensive guide, we’ll break down everything you need to know about debits and credits, complete with real-world examples and practical applications for your business.
What Are Debits and Credits in Accounting?
The Foundation of Double-Entry Bookkeeping
Debits and credits form the backbone of double-entry bookkeeping, a system that has been used for over 500 years. In this system, every financial transaction affects at least two accounts, and the total debits must always equal the total credits.
Debit comes from the Latin word “debere,” meaning “to owe.” In accounting, a debit is an entry on the left side of an account that increases assets and expenses or decreases liabilities, equity, and revenue.
Credit derives from the Latin “credere,” meaning “to trust” or “to believe.” A credit is an entry on the right side of an account that increases liabilities, equity, and revenue or decreases assets and expenses.
The Accounting Equation
The fundamental accounting equation underlies all debit and credit transactions:
Assets = Liabilities + Owner’s Equity
This equation must always balance, which is why the double-entry system works so effectively for maintaining accurate financial records.
How Debits and Credits Work: The T-Account Method
Understanding T-Accounts
A T-account is a visual representation of how debits and credits affect different account types. Picture a large “T” – debits go on the left side, credits on the right side.

The Five Account Types and Their Normal Balances
Understanding which accounts increase with debits versus credits is crucial:
1. Assets (Normal Debit Balance)
- Cash, Accounts Receivable, Inventory, Equipment
- Increase with debits, decrease with credits
2. Liabilities (Normal Credit Balance)
- Accounts Payable, Loans Payable, Credit Cards
- Increase with credits, decrease with debits
3. Owner’s Equity (Normal Credit Balance)
- Owner’s Capital, Retained Earnings
- Increase with credits, decrease with debits
4. Revenue (Normal Credit Balance)
- Sales Revenue, Service Revenue, Interest Income
- Increase with credits, decrease with debits
5. Expenses (Normal Debit Balance)
- Rent Expense, Office Supplies, Utilities
- Increase with debits, decrease with credits
Real-World Debit and Credit Examples for Small Businesses
Example 1: Making a Cash Sale
Your bakery sells $500 worth of pastries for cash.
Transaction Analysis:
- Cash (Asset) increases by $500 → Debit Cash $500
- Sales Revenue increases by $500 → Credit Sales Revenue $500
Journal Entry:
Debit: Cash $500
Credit: Sales Revenue $500
Example 2: Purchasing Office Supplies on Credit
You buy $200 worth of office supplies and agree to pay later.
Transaction Analysis:
- Office Supplies (Asset) increases by $200 → Debit Office Supplies $200
- Accounts Payable (Liability) increases by $200 → Credit Accounts Payable $200
Journal Entry:
Debit: Office Supplies $200
Credit: Accounts Payable $200
Example 3: Paying Monthly Rent
You pay $2,000 for office rent.
Transaction Analysis:
- Rent Expense increases by $2,000 → Debit Rent Expense $2,000
- Cash (Asset) decreases by $2,000 → Credit Cash $2,000
Journal Entry:
Debit: Rent Expense $2,000
Credit: Cash $2,000
Example 4: Receiving Payment from Customer
A customer pays $1,500 they owed you.
Transaction Analysis:
- Cash (Asset) increases by $1,500 → Debit Cash $1,500
- Accounts Receivable (Asset) decreases by $1,500 → Credit Accounts Receivable $1,500
Journal Entry:
Debit: Cash $1,500
Credit: Accounts Receivable $1,500
Example 5: Taking Out a Business Loan
Your business receives a $10,000 bank loan.
Transaction Analysis:
- Cash (Asset) increases by $10,000 → Debit Cash $10,000
- Notes Payable (Liability) increases by $10,000 → Credit Notes Payable $10,000
Journal Entry:
Debit: Cash $10,000
Credit: Notes Payable $10,000
Common Debit and Credit Mistakes to Avoid
Mistake 1: Confusing Bank Statement Terms
Your bank statement shows deposits as credits and withdrawals as debits from the bank’s perspective. This is opposite to how you record these transactions in your business books.
Mistake 2: Forgetting the Accounting Equation
Always ensure your debits equal your credits for each transaction. If they don’t balance, you’ve made an error.
Mistake 3: Mixing Up Normal Balances
Remember that assets and expenses have normal debit balances, while liabilities, equity, and revenue have normal credit balances.
Mistake 4: Recording Only One Side of a Transaction
Every transaction affects at least two accounts. Never record just a debit or just a credit without the corresponding entry.
Advanced Debit and Credit Concepts
Compound Journal Entries
Some transactions affect more than two accounts. For example, if you purchase equipment partly with cash and partly with a loan:
Transaction: Buy $5,000 equipment with $2,000 cash and $3,000 loan
Journal Entry:
Debit: Equipment $5,000
Credit: Cash $2,000
Credit: Notes Payable $3,000
Adjusting Entries
At the end of accounting periods, you’ll need to make adjusting entries to ensure accurate financial reporting. These follow the same debit and credit rules but often involve accruals and deferrals.
Closing Entries
Revenue and expense accounts are temporary and must be closed at year-end. This process transfers their balances to retained earnings using debits and credits.
How Technology Simplifies Debit and Credit Tracking
Modern Accounting Software
Today’s accounting software automatically handles much of the debit and credit complexity. However, understanding these fundamentals helps you:
- Review transactions for accuracy
- Understand financial reports
- Communicate effectively with your bookkeeper
- Make better business decisions
Integration with Banking
Bank feeds automatically import transactions, but you still need to categorize them correctly using debit and credit principles.

Frequently Asked Questions
What’s the difference between debit and credit in banking vs accounting?
In banking, a debit removes money from your account (like a debit card purchase), while a credit adds money (like a deposit). In accounting, debits and credits follow the rules of double-entry bookkeeping – debits increase assets and expenses, while credits increase liabilities, equity, and revenue.
Why do debits always equal credits?
The double-entry bookkeeping system requires debits to equal credits to maintain the fundamental accounting equation (Assets = Liabilities + Owner’s Equity). This ensures mathematical accuracy and helps identify errors quickly.
How do I know whether to debit or credit an account?
First, identify the account type (asset, liability, equity, revenue, or expense). Then determine if the transaction increases or decreases that account. Use the normal balance rules: assets and expenses increase with debits, while liabilities, equity, and revenue increase with credits.
What happens if my debits don’t equal my credits?
If debits don’t equal credits, you have an error in your books. This could be from entering wrong amounts, posting to incorrect accounts, or missing part of a transaction. You’ll need to review and correct the entries to restore balance.
Can a transaction have multiple debits or credits?
Yes, transactions can affect multiple accounts. The key rule is that total debits must equal total credits for each transaction, regardless of how many accounts are involved.
How often should I review my debit and credit entries?
Review entries daily when recording transactions, reconcile monthly with bank statements, and perform quarterly reviews of all accounts to ensure accuracy and catch any errors early.
