What Are Debits and Credits in Accounting?

Debits and credits are the two sides used to record transactions under double-entry bookkeeping.

Every financial transaction affects at least two accounts.

For each transaction:

Debit Meaning in Accounting

In accounting, a debit is an entry made on the left-hand side of an account.

Whether a debit increases or decreases the account depends on what kind of account it is.

As a general foundation:

• Debits increase assets.
• Debits increase expenses.
• Debits decrease liabilities.
• Debits decrease equity.
• Debits generally decrease income or revenue accounts.

This is why the meaning of a debit cannot be understood correctly without first identifying the account being affected.

For example, receiving cash increases the Cash account. Because Cash is an asset, the increase is recorded as a debit.

What Does Credit Mean in Accounting?

A credit is an entry made on the right-hand side of an account.

Again, its effect depends on the account type.

As a general foundation:

• Credits decrease assets.
• Credits decrease expenses.
• Credits increase liabilities.
• Credits increase equity.
• Credits increase income or revenue accounts.

A credit is therefore not automatically positive or negative.

It is simply one side of the accounting entry.

Learning this pattern can make transaction analysis considerably easier.

Instead of trying to memorise every transaction individually, first identify the accounts involved and then determine whether each account is increasing or decreasing.

What Is Double-Entry Bookkeeping?

Double-entry bookkeeping records both sides of every financial transaction.

If one account is debited, another account must be credited by the corresponding amount.

For example, suppose a business buys £500 of equipment and pays immediately in cash.

Two accounts are affected:

• Equipment increases.
• Cash decreases.

Both are assets.

The entry would therefore be:

The total debit is £500 and the total credit is £500.

The transaction remains balanced.

Why Does Every Transaction Have Two Sides?

Every transaction changes the financial position of an organisation in some way.

If a business receives something, there is normally another side explaining where it came from or what was exchanged for it.

For example:

Example: Receiving a Bank Loan

Suppose a business receives a £10,000 bank loan.

Two accounts change:

• Cash increases by £10,000.
• Loan liability increases by £10,000.

The entry is:

Cash is an asset, so its increase is debited.

The bank loan is a liability, so its increase is credited.

Example: Paying Rent

Suppose a business pays £1,000 in rent.

The transaction affects:

• Rent Expense
• Cash

Rent expense increases, while cash decreases.

Expenses generally increase on the debit side.

Assets such as cash decrease on the credit side.

Example: Making a Cash Sale

Suppose a business makes a £2,000 cash sale.

At a simplified introductory level:

• Cash increases.
• Sales revenue increases.

The entry is:

Cash is an asset and therefore increases with a debit.

Revenue increases with a credit.

Depending on the nature of the business and transaction, additional entries may also be needed, such as those relating to inventory and cost of sales.

Asset Accounts

Assets are resources controlled by a business.

Examples include:

• Cash
• Bank balances
• Inventory
• Equipment
• Vehicles
• Property
• Trade receivables

Asset accounts generally:

Liability Accounts

Liabilities represent obligations owed by the business.

Examples include:

• Bank loans
• Trade payables
• Accrued expenses
• Other amounts owed

Liabilities generally:

Income and Revenue Accounts

Income or revenue represents amounts earned through business activities.

Examples may include:

• Sales revenue
• Service income
• Fee income

Revenue generally increases with a credit.

This is why a cash sale can result in a debit to Cash and a credit to Sales Revenue.

Expense Accounts

Expenses represent costs incurred in operating the organisation.

Examples can include:

• Rent
• Utilities
• Wages
• Advertising
• Office expenses

Expenses generally increase with a debit.

Understanding this relationship becomes particularly important when learning how transactions eventually feed into profit and loss reporting.

For focused follow-on study, our Profit and Loss Accounts course explores this area in greater depth.

Debit Does Not Mean Debt

“Debit” and “debt” sound similar, but they do not mean the same thing.

A debt is an amount owed.

A debit is one side of an accounting entry.

A debit can relate to cash, equipment, expenses or many other accounts. It does not necessarily indicate that the business owes money.

Recognising this difference can prevent a common source of confusion when first studying accounting.

Debit Does Not Always Mean Money Out

Another common misconception is that debit always means money leaving a business.

It does not.

Consider cash received from a customer.

Cash increases, and an increase in an asset is recorded as a debit.

The everyday banking use of the words “debit” and “credit” can therefore create confusion when learners first encounter accounting terminology.

In accounting, always consider the account type and the effect of the transaction.

The Accounting Equation

Debits and credits support the accounting equation:

From Transactions to Financial Statements

Debits and credits are not isolated bookkeeping exercises.

They form part of the process that eventually produces financial information.

A simplified sequence is:

What Is a Ledger?

A ledger organises accounting entries into individual accounts.

Instead of viewing transactions only in chronological order, the ledger makes it possible to see activity relating to a specific account.

For example, the Cash ledger account collects entries affecting cash.

A business can then review:

• Opening balance
• Debits
• Credits
• Closing balance

Ledgers are central to the accounting process because they help organise transaction data before financial information is summarised.

What Is a Trial Balance?

A trial balance lists ledger account balances and separates them into debit and credit columns.

If the double-entry records are arithmetically balanced:

Common Debit and Credit Mistakes

When learning debit and credit accounting, several mistakes are particularly common.

Treating Debit as “Bad” and Credit as “Good”

Neither term indicates whether something is favourable.

They describe the side of an accounting entry.

Assuming Debit Always Means Cash Out

An increase in Cash is normally a debit.

Ignoring the Account Type

You cannot determine the correct entry without knowing whether the account is an asset, liability, equity, income or expense.

Recording Only One Side

Double-entry bookkeeping requires corresponding entries.

Confusing Bank Statements with Business Accounting Records

A bank may describe transactions from the bank's perspective, which can differ from the way the business records its own cash account.

A Simple Method for Analysing Transactions

When faced with a transaction, work through it systematically.

Step 1: Identify the Accounts

Ask which accounts are affected.

Step 2: Classify Each Account

Determine whether each is an:

• Asset
• Liability
• Equity account
• Income account
• Expense account

Step 3: Decide What Changed

Did each account increase or decrease?

Step 4: Apply the Debit and Credit Rules

Use the account classification to determine which side should be debited and which should be credited.

Step 5: Check the Totals

Make sure total debits equal total credits.

This method is more reliable than trying to memorise isolated journal entries.
