Debits and credits can seem confusing when you first learn accounting. A debit can increase one account but decrease another, while a credit can do the opposite.
The confusion usually comes from treating debit as “money out” and credit as “money in.” That may seem logical when looking at a bank account, but it is not how debits and credits work in accounting.
This guide explains debits and credits for beginners using clear rules, practical examples, T-accounts, and a repeatable four-step method. You will learn what debits and credits mean, how they affect each account type, and how to decide which account to debit or credit.

Debits and credits are the two sides used to record transactions in double-entry accounting. A debit is recorded on the left side of an account, while a credit is recorded on the right.
Assets and expenses normally increase with debits. Liabilities, equity, and revenue normally increase with credits. Total debits must equal total credits in every complete journal entry.
| Account Type | Debit | Credit | Normal Balance |
|---|---|---|---|
| Assets | Increase | Decrease | Debit |
| Expenses | Increase | Decrease | Debit |
| Liabilities | Decrease | Increase | Credit |
| Equity | Decrease | Increase | Credit |
| Revenue | Decrease | Increase | Credit |
Do not memorize “debit = increase” or “credit = decrease.” Identify the account type first, then determine whether the account increased or decreased.
What Are Debits and Credits in Accounting?
In accounting, a debit is an entry on the left side of an account, and a credit is an entry on the right. Neither term automatically means an increase or decrease. The effect depends on the type of account.
Suppose a business pays $1,000 cash for equipment. Equipment increases, while Cash decreases. Both accounts are assets, but they move in opposite directions.
Equipment increases with a debit. Cash decreases with a credit.
| Account | Debit | Credit |
|---|---|---|
| Equipment | $1,000 | — |
| Cash | — | $1,000 |
This example shows why you should not define debit as “money out” or credit as “money in.”
What Does Debit Mean?
A debit, abbreviated as Dr., is an entry on the left side of an account.
A debit can increase or decrease an account depending on the account type. It increases assets and expenses but decreases liabilities, equity, and revenue.
For example, when a business receives cash from a customer, its Cash account increases. Because Cash is an asset, the increase is recorded as a debit.
What Does Credit Mean?
A credit, abbreviated as Cr., is an entry on the right side of an account.
Credits increase liabilities, equity, and revenue. They decrease assets and expenses.
For example, when a business pays cash to a supplier, its Cash account decreases. Because Cash is an asset, that decrease is recorded as a credit.
Account type → Increase or decrease → Debit or credit
How Do Debits and Credits Work in Accounting?
Debits and credits work through double-entry bookkeeping. Transactions are recorded so that total debit amounts equal total credit amounts.
This system records the full financial effect of a transaction instead of recording only one side.
Double-Entry Bookkeeping
The IRS explains double-entry bookkeeping as a system that uses journals and ledgers, with debits recorded on the left side of an account and credits on the right.
Suppose a business borrows $10,000 from a bank.
- Cash increases by $10,000.
- Loan Payable increases by $10,000.
Cash is an asset, so its increase is recorded as a debit. Loan Payable is a liability, so its increase is recorded as a credit.
| Account | Debit | Credit |
|---|---|---|
| Cash | $10,000 | — |
| Loan Payable | — | $10,000 |
Total debits are $10,000 and total credits are $10,000. The business did not earn $10,000 of revenue. It received cash and also created a liability that must be repaid.
Debits, Credits, and the Accounting Equation
Debits and credits also support one of the most important ideas in Accounting Basics : the accounting equation.
In the borrowing example, Cash increases assets by $10,000. Loan Payable increases liabilities by the same amount. The equation remains balanced.
The SEC presents the same basic balance-sheet relationship: assets equal liabilities plus shareholders’ equity.
Debit and Credit Rules for Each Account Type
Assets and expenses normally increase with debits. Liabilities, equity, and revenue normally increase with credits.
These categories also align with major financial statement elements described in the FASB Conceptual Framework.
| Account Type | Increase With | Decrease With |
|---|---|---|
| Assets | Debit | Credit |
| Expenses | Debit | Credit |
| Liabilities | Credit | Debit |
| Equity | Credit | Debit |
| Revenue | Credit | Debit |
Assets
Assets are economic resources a business owns or controls. Common examples include:
- Cash
- Accounts Receivable
- Inventory
- Supplies
- Equipment
- Prepaid Expenses
Assets increase with debits and decrease with credits.
Liabilities
Liabilities are obligations a business owes to other parties. Common examples include:
- Accounts Payable
- Notes Payable
- Loans Payable
- Wages Payable
- Unearned Revenue
Liabilities increase with credits and decrease with debits.
Equity
Equity represents the owners’ residual interest in a business after liabilities are deducted from assets.
Account names may include Owner’s Capital, Common Stock, or Retained Earnings.
Equity normally increases with credits and decreases with debits.
Revenue
Revenue represents amounts earned from providing goods or services. Examples include Service Revenue, Sales Revenue, Interest Revenue, and Rental Revenue.
Revenue normally increases with credits and decreases with debits.
Expenses
Expenses are costs incurred while operating a business. Examples include Rent Expense, Utilities Expense, Wages Expense, Advertising Expense, and Insurance Expense.
Expenses normally increase with debits and decrease with credits.
What Is a Normal Balance?
A normal balance is the debit or credit side on which an account normally increases and usually carries its balance.
Assets and expenses normally have debit balances. Liabilities, equity, and revenue normally have credit balances.
For example, Cash normally has a debit balance because increases in Cash are recorded as debits. Accounts Payable normally has a credit balance because increases in that liability are recorded as credits.
For a practical liability example, see our complete guide to Accounts Payable .
How to Know Whether to Debit or Credit an Account
To determine which account to debit or credit, identify the accounts affected, classify each account, decide whether it increased or decreased, and then apply the correct debit and credit rule.
Use the same four-step reasoning process for nearly every beginner transaction.
Consider this transaction: A business pays $800 cash for rent.
Identify the Accounts Affected
Ask what changed because of the transaction. The affected accounts are Rent Expense and Cash.
Classify Each Account
Rent Expense is an expense account. Cash is an asset account.
Determine Whether Each Account Increased or Decreased
Rent Expense increased because the business incurred rent. Cash decreased because the business paid $800.
Apply the Debit and Credit Rules
Expenses increase with debits. Assets decrease with credits. Therefore, Rent Expense is debited and Cash is credited.
| Account | Debit | Credit |
|---|---|---|
| Rent Expense | $800 | — |
| Cash | — | $800 |
Finally, verify the totals: Total debits = $800 and total credits = $800.
Do not ask, “Is this transaction a debit or credit?”
Ask: “Which accounts changed, what type are they, and did each increase or decrease?”
How Debits and Credits Work in a T-Account
A T-account is a simple visual tool that shows debit and credit activity for one account. Debits appear on the left, while credits appear on the right.
Suppose a Cash T-account contains a $5,000 debit and an $800 credit.
| Debit — Left | Credit — Right |
|---|---|
| $5,000 | $800 |
Cash is an asset. The $5,000 debit increases Cash, while the $800 credit decreases Cash.
The resulting balance is: $5,000 − $800 = $4,200 debit balance.
T-accounts become especially useful when you study journal entries and how individual account activity eventually appears in the general ledger .
Debits and Credits Examples
The easiest way to understand debits and credits is to apply the rules to real transactions.
For each example, follow the same pattern: Accounts → Account types → Increase or decrease → Debit or credit.
Example 1: Owner Invests Cash
An owner invests $10,000 in a sole proprietorship. Cash increases, and Owner’s Capital increases.
| Account | Debit | Credit |
|---|---|---|
| Cash | $10,000 | — |
| Owner’s Capital | — | $10,000 |
Cash is an asset, so it increases with a debit. Owner’s Capital is an equity account, so it increases with a credit.
Learn more about contributions, profits, and withdrawals in our guide to owner’s equity .
Example 2: Business Pays Rent
The business pays $1,200 cash for monthly rent. Rent Expense increases, while Cash decreases.
| Account | Debit | Credit |
|---|---|---|
| Rent Expense | $1,200 | — |
| Cash | — | $1,200 |
The fact that cash went out does not make the entire transaction a “debit.” Each account is analyzed separately.
Example 3: Business Buys Equipment for Cash
The business buys equipment for $4,000 cash. Equipment increases, while Cash decreases. Both accounts are assets.
| Account | Debit | Credit |
|---|---|---|
| Equipment | $4,000 | — |
| Cash | — | $4,000 |
This transaction shows why a debit does not automatically mean an expense. Equipment receives a debit even though it is an asset.
Example 4: Business Buys Supplies on Credit
The business buys $800 of supplies and agrees to pay the supplier later. Supplies increases, and Accounts Payable increases.
| Account | Debit | Credit |
|---|---|---|
| Supplies | $800 | — |
| Accounts Payable | — | $800 |
No cash moves when the purchase is initially made. The credit creates Accounts Payable , a liability representing the amount owed to the supplier.
Example 5: Business Earns Cash Revenue
A company provides services and receives $2,500 immediately. Cash increases, and Service Revenue increases.
| Account | Debit | Credit |
|---|---|---|
| Cash | $2,500 | — |
| Service Revenue | — | $2,500 |
The Cash asset increases with a debit, while Service Revenue increases with a credit.
Example 6: Business Provides Services on Account
Under accrual accounting, suppose a company provides $3,000 of services to a customer and allows the customer to pay later.
The company has earned the revenue but has not collected the cash. Accounts Receivable increases, and Service Revenue increases.
| Account | Debit | Credit |
|---|---|---|
| Accounts Receivable | $3,000 | — |
| Service Revenue | — | $3,000 |
Example 7: Customer Later Pays the Receivable
The customer later pays the $3,000 balance. Cash increases, while Accounts Receivable decreases.
| Account | Debit | Credit |
|---|---|---|
| Cash | $3,000 | — |
| Accounts Receivable | — | $3,000 |
Service Revenue is not credited again. Under accrual accounting, the revenue was recorded when it was earned. Collecting the receivable simply exchanges one asset—Accounts Receivable— for another asset—Cash.
Example 8: Business Pays Accounts Payable
The business pays the $800 amount owed to the supplier from Example 4. Accounts Payable decreases, and Cash decreases.
| Account | Debit | Credit |
|---|---|---|
| Accounts Payable | $800 | — |
| Cash | — | $800 |
The debit reduces the liability, while the credit reduces the Cash asset.
How to Remember Debits and Credits
A useful way to remember debits and credits is to group assets and expenses on the debit side and liabilities, equity, and revenue on the credit side.
One common memory aid is DEALER.
Debit Increases
- D — Dividends or Drawings
- E — Expenses
- A — Assets
Credit Increases
- L — Liabilities
- E — Equity
- R — Revenue
The mnemonic is useful, but it should support your understanding rather than replace it.
Account type → Increase or decrease → Debit or credit
Why Do Bank Debits and Credits Seem Backwards?
Bank debits and credits can seem backward because your bank statement reflects the bank’s accounting perspective, not your own bookkeeping perspective.
Suppose you deposit $1,000 into your checking account.
In your accounting records, your Cash asset increases. An increase in an asset is normally recorded as a debit.
From the bank’s perspective, however, the deposit represents an amount the bank owes you. That customer deposit is generally a liability for the bank. When the bank’s liability increases, the bank records a credit.
| Perspective | Accounting Effect |
|---|---|
| Your Books | Cash asset increases → Debit |
| Bank’s Books | Customer deposit liability increases → Credit |
The terminology is not actually reversed. The two parties are recording the same transaction from different accounting perspectives.
Common Debit and Credit Mistakes Beginners Make
Most beginner mistakes happen when debit is treated as “plus” and credit as “minus” without first identifying the account type.
Mistake 1: Assuming Every Debit Is an Increase
A debit increases assets and expenses, but it decreases liabilities, equity, and revenue. Always classify the account first.
Mistake 2: Assuming Every Credit Is a Decrease
Credits decrease assets and expenses but increase liabilities, equity, and revenue. A credit to Revenue normally represents an increase in revenue.
Mistake 3: Treating Debit as Money Out
Cash received by a business can create a debit to Cash. Buying equipment can also create a debit to Equipment. Debit refers to the left side of an account, not necessarily cash leaving the business.
Mistake 4: Looking Only at Cash
Not every accounting transaction immediately involves cash. Buying supplies on account affects Supplies and Accounts Payable. Providing services on account under accrual accounting affects Accounts Receivable and Revenue.
Mistake 5: Recording Only One Side
A complete double-entry journal entry requires equal total debits and credits. Recording only one side leaves the entry incomplete.
Mistake 6: Assuming a Balanced Entry Must Be Correct
Equal debits and credits prove only that the entry is mathematically balanced. You can still use the wrong account even when both totals match.
Account balances are later summarized in a trial balance to compare total debit balances with total credit balances.
Mistake 7: Recording Revenue Again When Cash Is Collected
If revenue was previously recorded under accrual accounting when it was earned, collecting the related receivable does not create new revenue. The collection debits Cash and credits Accounts Receivable.
Debits and Credits Practice for Beginners
The best way to learn debits and credits is to practice identifying the account type before choosing the debit or credit side.
Question 1
A business pays $900 cash for monthly rent. Which account is debited?
Question 2
A business borrows $20,000 from a bank and receives the cash. Which account is credited?
Question 3
A company earns $1,500 cash by providing services. Which account receives the debit?
Question 4
A business buys $600 of supplies on account. Which liability account is credited?
Question 5
Under accrual accounting, a customer pays a $2,000 Accounts Receivable balance that was recorded earlier. Should Revenue be credited again?
Answers
1. Rent Expense is debited. The expense increases, and expenses normally increase with debits. Cash decreases and receives the credit.
2. Loan Payable is credited. The business created a liability. Liabilities increase with credits. Cash increases and receives the debit.
3. Cash is debited. Cash is an asset, and assets increase with debits. Service Revenue receives the credit.
4. Accounts Payable is credited. The business now owes the supplier. The liability increases with a credit, while Supplies increases with a debit.
5. No. Revenue is not credited again. The revenue was previously recorded when earned. The collection increases Cash and decreases Accounts Receivable.

Frequently Asked Questions About Debits and Credits
Are Debits Positive and Credits Negative?
No. Debits are not inherently positive, and credits are not inherently negative. Their effect depends on the account type. A debit increases assets and expenses but decreases liabilities, equity, and revenue. Credits have the opposite effect.
Do Debits and Credits Always Have to Equal?
Total debits and total credits must be equal in a complete double-entry journal entry. Equal totals keep the entry mathematically balanced. However, the entry can still be wrong if the wrong accounts or amounts were selected.
Is Cash a Debit or Credit?
Cash is an asset and normally has a debit balance. An increase in Cash is recorded as a debit, while a decrease is recorded as a credit. Receiving cash therefore normally debits Cash, while paying cash normally credits Cash.
Is Revenue a Debit or Credit?
Revenue normally has a credit balance. Revenue increases with credits and decreases with debits. The other side depends on the transaction. Earned cash revenue normally debits Cash, while revenue earned on account under accrual accounting normally debits Accounts Receivable.
Are Expenses Debits or Credits?
Expenses normally have debit balances. An expense generally increases with a debit and decreases with a credit. For example, if a business incurs and pays $500 of utilities expense, it normally debits Utilities Expense and credits Cash.
Which Side Is Debit and Which Side Is Credit?
Debit is always the left side of an account, and credit is always the right side. The left-right position never changes. What changes is whether the debit or credit increases or decreases the account, which depends on the account type.
Can the Same Account Have Both Debits and Credits?
Yes. The same account can receive both debits and credits over time. Cash, for example, is debited when it increases and credited when it decreases. In a normal transaction, debiting and crediting the same account for identical amounts would usually cancel itself out.
The Bottom Line
Debits and credits become much easier once you stop treating them as positive and negative numbers.
Remember that debit means left and credit means right. Assets and expenses normally increase with debits, while liabilities, equity, and revenue normally increase with credits.
When analyzing a transaction, use the same process every time: identify the accounts → classify them → determine whether they increased or decreased → apply the debit and credit rules.
Then verify that total debits equal total credits.
