Debit is the left side. In every standard accounting T-account, debits are recorded on the left of the vertical line and credits are recorded on the right. This rule never changes regardless of the type of account you’re working with.
Why Left and Right Matter
Double-entry bookkeeping uses a simple visual tool called a T-account. Picture the letter “T” drawn on a page: the account name sits on top, and the vertical line splits the space into two columns. The left column is always for debits, and the right column is always for credits. Every financial transaction gets recorded as at least one debit entry and one credit entry, and the two sides must balance.
The words themselves have Latin roots. “Debit” comes from “debere” (to owe), and “credit” comes from “credere” (to trust or entrust). But in practice, you can forget the Latin. What matters is that debit means left and credit means right, every single time.
What Debits and Credits Do to Different Accounts
The left-or-right placement never changes, but the effect of a debit or credit depends on which type of account you’re recording it in. This is usually the part that trips people up.
- Assets (cash, equipment, inventory): A debit increases the balance, a credit decreases it. Normal balance is a debit (left).
- Expenses (rent, wages, utilities): A debit increases the balance, a credit decreases it. Normal balance is a debit (left).
- Liabilities (loans, accounts payable): A credit increases the balance, a debit decreases it. Normal balance is a credit (right).
- Equity (owner’s capital, retained earnings): A credit increases the balance, a debit decreases it. Normal balance is a credit (right).
- Revenue (sales, service income): A credit increases the balance, a debit decreases it. Normal balance is a credit (right).
Think of it this way: the “normal balance” tells you which side the account naturally sits on. Asset and expense accounts live on the left (debit) side of the accounting equation. Liabilities, equity, and revenue live on the right (credit) side. When you record a transaction on the account’s normal side, the balance goes up. When you record it on the opposite side, the balance goes down.
A Quick Memory Trick
One popular mnemonic is DEAD CLIC:
- DEAD: Debits increase Expenses, Assets, and Dividends (or Drawings).
- CLIC: Credits increase Liabilities, Income, and Capital.
You may also see variations like DEAD RELIC, which rearranges the credit side to include Revenue, Equity, and Liabilities. Pick whichever version sticks. The core idea is the same: certain account types go up with debits, and the rest go up with credits.
Why Your Bank Statement Seems Backward
If you’ve looked at a bank statement and seen “debit” next to a withdrawal, you might wonder why a debit lowers your balance when the rules above say debits increase assets. The answer is perspective. Your bank account is an asset to you, but it’s a liability to the bank because the bank owes you that money. When the bank “debits” your account on its books, it’s reducing its liability to you, which shows up as a smaller balance on your statement. The accounting rules haven’t changed. You’re just seeing the transaction from the bank’s side of the ledger, not yours.
Putting It Into Practice
Suppose you buy $500 worth of office supplies with cash. Two accounts are affected: your cash account (an asset) goes down by $500, and your supplies expense account goes up by $500. In T-account form, you’d place a $500 credit on the right side of the cash account (decreasing it) and a $500 debit on the left side of the expense account (increasing it). Left side equals right side, and the books stay balanced.
No matter how complex a transaction gets, every journal entry follows the same pattern: debits on the left, credits on the right, and the totals of each side match. Once that positioning clicks, the rest of accounting builds on top of it.
