Debits and Credits Explained Using T-Accounts in Double Entry Accounting

Ask most people what a "debit" means and they'll say "money going out" — because that's what their bank statement says. Ask them what a "credit" means and they'll say "money coming in." Both answers are wrong in accounting terms, and that one misunderstanding causes more confusion in bookkeeping than almost anything else.

Let's fix that once and for all — with T-accounts, real examples, and a memory trick that means you'll never have to guess again.

This article is part of a series. If you're new to double entry, you might want to start with how profit or loss affects capital in double entry accounting first — then come back here. If you're ready to dig into debits and credits specifically, you're in the right place.

What Are Debits and Credits?

Definition

In double entry accounting, a debit is an entry on the left side of a ledger account, and a credit is an entry on the right side. Whether a debit increases or decreases an account depends entirely on the type of account — not on whether money is coming in or going out.

This is the single most important thing to understand about debits and credits. They are directions — left and right — not value judgements. A debit is not "good" or "bad." A credit is not "good" or "bad." The meaning depends on which type of account you're applying them to.

💡 Why Your Bank Statement Confused You

Your bank says "credit" when money arrives in your account. That's because from the bank's perspective, your account is a liability — they owe you that money. When your balance increases, their liability increases — and liabilities increase with credits. The bank isn't wrong. But their accounting is from their side, not yours. In your books, cash arriving is a debit to your Cash account — because cash is an asset, and assets increase with debits.

What Is a T-Account?

A T-account is a visual representation of a ledger account — drawn in the shape of the letter T. Every account in your books has a T-account behind it. The account name goes at the top. Debits go on the left. Credits go on the right.

T-accounts are used by accountants, students, and bookkeepers to map out transactions before recording them. They're the fastest way to check whether your debits and credits are correct before posting to the ledger. For more on how ledger accounts work in the full system, see our guide on what a ledger account is and how businesses use them.

The Rule Every Bookkeeper Lives By: DEAD CLIC

Here's the memory trick. Once you've learned it you won't forget it:

The DEAD CLIC Mnemonic — Which Accounts Increase with Debit vs Credit

DEBIT increases:

• Drawings (owner takes money out)
• Expenses (rent, wages, fuel)
• Assets (cash, equipment, receivables)
• Dividends (distributions to shareholders)

CREDIT increases:

• Capital (owner's equity)
• Liabilities (loans, payables)
• Income (sales, fees, revenue)
• Creditors (amounts owed to suppliers)

Memorise DEAD CLIC and you can work out the correct side for any transaction without hesitating. The opposite is always true for decreases — if an asset normally increases with a debit, it decreases with a credit. Every time, without exception.

Account Type	Increases with	Decreases with	Normal Balance
Assets	Debit (left)	Credit (right)	Debit
Liabilities	Credit (right)	Debit (left)	Credit
Capital / Equity	Credit (right)	Debit (left)	Credit
Revenue / Income	Credit (right)	Debit (left)	Credit
Expenses	Debit (left)	Credit (right)	Debit
Drawings	Debit (left)	Credit (right)	Debit

This table connects directly to the accounting equation (Assets = Liabilities + Capital). Notice that assets are on the left side of the equation — and they increase with debits, which go on the left side of the T-account. Liabilities and capital are on the right side of the equation — and they increase with credits, which go on the right. It's the same logic, just two different presentations of the same truth.

Debits and Credits for Expenses

This is where most beginners trip up. Expenses increase with debits. Not because paying for something is "positive" — but because expenses reduce profit, which reduces capital. And since capital lives on the credit side, anything that reduces it sits on the opposite side: debit.

Every expense entry follows this pattern:

DR Expense Account     CR Cash / Bank (or Accounts Payable)

The expense goes up on the debit side. The payment source goes down on the credit side (cash reduces) — or a liability goes up on the credit side (if paying later).

Three Expense Examples in T-Accounts

Notice that example 2 — the unpaid fuel — uses the exact same debit to Fuel Expense. The only difference is the credit side: instead of reducing cash (which hasn't left yet), it creates an Accounts Payable liability. Same expense, same debit. Different credit depending on whether you've paid yet or not.

Debits and Credits for Revenue

Revenue is the opposite of expenses. Revenue increases with credits — because revenue increases profit, which increases capital, which lives on the credit side.

DR Cash / Bank (or Accounts Receivable)     CR Revenue Account

When you earn income, your asset goes up (debit) and your revenue goes up (credit). Whether the cash has arrived yet or not, the revenue is credited the moment it's earned.

Transaction	Debit	Credit	Why
Client pays $3,600 cash for project	Bank $3,600	Sales Revenue $3,600	Asset up / Income up
Invoice $5,000 sent (not yet paid)	Accounts Receivable $5,000	Sales Revenue $5,000	Receivable up / Income up
Commission earned $150 cash	Cash $150	Commission Income $150	Asset up / Income up
Revenue entry reversed (return)	Sales Revenue $400	Accounts Receivable $400	Income down / Asset down

Revenue stays credited in its account until the end of the accounting period, when it gets transferred to the Income Statement. This transfer is part of the closing entry process — the same process covered in our article on how profit or loss affects capital.

Drawings — When the Owner Takes Money Out

Every business owner takes money out for personal use at some point. In accounting, these withdrawals are called drawings — and they have their own account, separate from expenses.

Why separate? Because drawings are not a business expense. They don't reduce profit. They reduce the owner's capital directly. If you merged drawings into expenses, your profit figure would be wrong — it would look like the business is less profitable than it actually is.

📌 Drawings ≠ Expenses

Taking $500 out of the business for a personal purchase is not a business cost. It doesn't appear on your Profit & Loss statement. It reduces your Capital account on the Balance Sheet. This distinction is critical for accurate financial statements and for understanding how the balance sheet equation stays balanced.

The double entry for cash drawings:

DR Drawings Account     CR Bank

Capital reduces (via the drawings account) and cash reduces. At year end, the Drawings account is closed off against Capital — reducing the owner's equity by the total withdrawn.

When an owner takes stock (goods) instead of cash:

DR Drawings Account     CR Purchases Account

The stock leaves the business — so Purchases (which was debited when stock arrived) is now credited to reverse that entry. Capital reduces, stock reduces. The accounting equation stays balanced throughout.

📋 Real Scenario: John Takes $250 for Personal Use

John runs a small grocery business. On September 24, he takes $250 from the business till for personal expenses. The business records: DR Drawings $250, CR Bank $250. The Drawings account now has a $250 debit balance. At year end, this is transferred: DR Capital $250, CR Drawings $250 — closing the drawings account and reducing John's capital balance by $250. His profit for the year isn't affected. But his equity is.

A Complete Week of Transactions — In T-Accounts

Let's take a full week of real business transactions and map every one of them into T-accounts. This is exactly the kind of exercise that makes the system click.

The closing balance of $10,650 DR means the business holds $10,650 in its bank account. The debit balance confirms it's an asset — assets carry debit balances. If this were a liability account, a credit balance would mean the business owes that amount.

Test Yourself — Debit or Credit?

Debit or Credit? Quick-Fire Quiz

Select the correct side for each transaction — immediate feedback on every answer

1. You receive $2,400 cash from a client. Which account is DEBITED?

✅ Correct. Cash arrives → Bank is an asset → Assets increase with a debit. The credit goes to Sales Revenue (income increases with a credit).

2. You pay $800 rent by bank transfer. Which account is CREDITED?

✅ Correct. Bank is credited — cash leaves the business, so the asset decreases (credit). Rent Expense is debited because expenses increase with a debit.

3. You take a $5,000 bank loan. Which account is CREDITED?

✅ Correct. The loan is a liability — liabilities increase with credits. Bank is debited because cash (an asset) increases with a debit.

4. Owner withdraws $300 cash for personal use. Which account is DEBITED?

✅ Correct. Drawings reduce the owner's capital — the Drawings account is debited. Never use an Expense account for personal withdrawals. Bank is credited (cash leaves).

5. You invoice a client $1,800 — not yet paid. Which account is DEBITED?

✅ Correct. Accounts Receivable (an asset) is debited — it increases because someone now owes you money. Sales Revenue is credited (income increases with a credit). No cash yet.

The Golden Rule: Total Debits Always Equal Total Credits

In a properly maintained set of books, the total of all debit balances across all accounts must equal the total of all credit balances. This is verified by preparing a trial balance at the end of each period.

If the trial balance doesn't balance — debits don't equal credits — there's a recording error somewhere. Something was posted to only one side, or posted to the wrong account, or entered at the wrong amount. The imbalance tells you there's a problem, even if it doesn't tell you exactly where.

For a detailed walkthrough of how the trial balance works and how to prepare one, see our guide on understanding the chart of accounts — which explains how all your accounts are organised before the trial balance is prepared.

⚠ The Most Common Mistake

Posting a transaction to the wrong side of an account. A payment of rent that should be DR Rent Expense / CR Bank gets entered as DR Bank / CR Rent Expense instead. Both accounts have an entry, so it looks complete — but the effect is reversed. Cash appears to go up instead of down. This is called a reversal error and it won't be caught by checking for missing entries alone. Always verify both the account name and the side before posting.

Frequently Asked Questions

What is the difference between a debit and a credit in simple terms?

A debit is an entry on the left side of a T-account. A credit is an entry on the right side. Whether a debit increases or decreases an account depends on the account type. Assets and expenses increase with debits. Liabilities, capital, and revenue increase with credits. Neither is inherently "good" or "bad" — they're just directions in the recording system.

Why do assets increase with a debit when debit sounds negative?

The words "debit" and "credit" have no positive or negative connotation in accounting — they're purely directional (left and right). Assets sit on the left side of the accounting equation (Assets = Liabilities + Capital), so they carry debit (left-side) balances and increase with entries on the left. It's a system convention, not a value judgement.

What happens if debits don't equal credits?

The books are out of balance and there's a recording error somewhere. The trial balance will flag this. You'll need to trace through your journal entries to find where a transaction was posted to one side only, to the wrong account, or at the wrong amount. The double-entry system exists precisely to catch this kind of error early.

Are drawings an expense or a reduction in capital?

Drawings are a reduction in capital — not an expense. They don't appear on the Profit & Loss statement and don't reduce business profit. They appear on the Balance Sheet as a reduction in the owner's equity. At year end, the Drawings account is closed off against the Capital account. Never record personal withdrawals as business expenses — it distorts your profit figure.

How does the DEAD CLIC mnemonic work?

DEAD stands for Drawings, Expenses, Assets, Dividends — all of which increase with a Debit. CLIC stands for Capital, Liabilities, Income, Creditors — all of which increase with a Credit. Memorise those eight items and you can work out the correct side of any transaction without hesitation. The decrease side is always the opposite.
