Debits and credits

A debit (Dr) is the left side of a journal entry and a credit (Cr) is the right side. Debits increase assets, expenses and dividends or draws; credits increase liabilities, equity and revenue. In every entry total debits equal total credits, which is what keeps the books in balance.

Syntax

Dr Account (increase assets, expenses, dividends) / Cr Account (increase liabilities, equity, revenue)
PartWhat it is
AssetsDebit to increase, credit to decrease. Normal balance: debit.
ExpensesDebit to increase, credit to decrease. Normal balance: debit.
Dividends / DrawingsDebit to increase. Normal balance: debit.
LiabilitiesCredit to increase, debit to decrease. Normal balance: credit.

Examples

Dr Cash 5,000 / Cr Service Revenue 5,000

Result: Assets up 5,000, revenue (equity) up 5,000

Cash is an asset, so it is debited to increase it; revenue is credited to increase it.

Dr Rent Expense 1,200 / Cr Cash 1,200

Result: Expenses up 1,200, assets down 1,200

An expense is debited; the asset paid out is credited.

Dr Accounts Payable 800 / Cr Cash 800

Result: Liabilities down 800, assets down 800

Paying a liability debits it (decrease) and credits cash (decrease).

Common mistakes

  • Treating debit as always good and credit as always bad: debit and credit only mean left and right, and the effect depends on the account type.
  • Crediting an expense when it is paid: paying rent debits Rent Expense and credits Cash, never the other way round.
  • Mixing up the bank statement view with the company view: the bank credits your account when you deposit because your deposit is a liability to the bank, but in your own books cash is debited.
  • Writing an entry where debits and credits do not match: every entry must balance, so re-add both columns before posting.

Questions

Is a debit an increase or a decrease?

It depends on the account. A debit increases assets, expenses and dividends, and decreases liabilities, equity and revenue.

What does DEALER stand for in accounting?

DEALER is a memory aid: Dividends, Expenses and Assets have debit normal balances; Liabilities, Equity and Revenue have credit normal balances.

Why does my bank say credit when I deposit money?

The bank records your deposit from its own point of view, where your balance is a liability it owes you, so it credits that liability. In your books the same deposit is a debit to Cash.
