Debits and credits cheat sheet

The rules on one page, including the contra accounts and drawings that trip people up.

The one rule

A posting on an account's normal-balance side increases it; a posting on the other side decreases it.

Assets, expenses and drawings have normal debit balances. Liabilities, capital and revenue have normal credit balances. Contra accounts take the opposite side of the account they offset.

Memory check

If you're unsure, rebuild it from the equation: Assets (left) = Liabilities + Equity (right). Left-side items increase on the left (debit); right-side items increase on the right (credit). Revenue increases equity (credit); expenses decrease it (debit).
