What are Debits and Credits?

Debits and credits are the two sides of every accounting entry under double-entry bookkeeping. Every transaction affects at least two accounts, and total debits must always equal total credits. Understanding the debit/credit rule for each account type lets you record any transaction correctly and keep the books in balance.

Short answer

A debit (left side) increases assets, expenses, and dividends and decreases liabilities, equity, and revenue; a credit (right side) does the opposite. Total debits must always equal total credits.

Effect of Debits vs. Credits by Account Type
Debit (left side) increases…
  • Assets (Cash, Equipment)
  • Expenses (Rent, Salaries)
  • Dividends / Draws
Credit (right side) increases…
  • Liabilities (Loans Payable)
  • Equity (Common Stock)
  • Revenue (Sales)

Step-by-step worked examples

Cash starts the month at $5,000. During the month, $3,000 is debited and $1,000 is credited to Cash. What's the ending balance?

Cash is debit-normal -> Ending = Beginning + Debits − Credits
Ending = 5,000 + 3,000 − 1,000
Ending = $7,000

A company pays $800 rent in cash. Journalize the entry.

Rent Expense increases -> debit Rent Expense $800
Cash decreases -> credit Cash $800
Debits ($800) = Credits ($800) — the entry balances

Accounts Payable begins at $2,000 (credit balance). The company is credited $1,500 more in purchases and debits (pays) $500. What's the ending balance?

Accounts Payable is credit-normal -> Ending = Beginning + Credits − Debits
Ending = 2,000 + 1,500 − 500
Ending = $3,000
