Debits and credits

Debits and credits

For the accounts to remain in balance, a change in one account must be matched with a change in another account. These changes are made by debits and credits to the accounts. Note that the usage of these terms in accounting is not identical to their everyday usage. Whether one uses a debit or credit to increase or decrease an account depends on the normal balance of the account. Assets, Expenses, and Drawings accounts (on the left side of the equation) have a normal balance of debit. Liability, Revenue, and Capital accounts (on the right side of the equation) have a normal balance of credit. On a general ledger, debits are recorded on the left side and credits on the right side for each account. Since the accounts must always balance, for each transaction there will be a debit made to one or several accounts and a credit made to one or several accounts. The sum of all debits made in any transaction must equal the sum of all credits made. After a series of transactions, therefore, the sum of all the accounts with a debit balance will equal the sum of all the accounts with a credit balance.
Debits and credits are then defined as follows:

• Debit: A debit is recorded on the left hand side of a T account. it can also be defined as increase in asset and expenses while decrease in liability, revenue and capital.
• Credit: A credit balance is recorded on the right hand side of a 'T' account Credit can also be defined as increase in liability, revenue and capital and decrease in assets and expenses.
• Debit accounts = Asset and Expenses (also debit money received into bank accounts)
• Credit accounts = Gains (income) and Liabilities (also credit money paid out of bank accounts)

Double entry example 1

• Sales Invoice Daybook (records customer Invoice Daybook)
• Bank Receipts Daybook (records customer & non customer receipts)
• Purchase Invoice Daybook (records supplier Invoice Daybook)
• Bank Payments Daybook (records supplier & non supplier payments)
