Accounting is based on the double entry principle. This principle states that for every credit entry there must be a corresponding debit entry. This means that everything must balance out.Think of an account having two sides, the debit and the credit. Using an Example, if a bank gave me loan of £1,000. I will Debit my Bank account with £1,000 and credit my loan account because it is a liability with £1,000. Therefore it balances out. Always think of it like this:DEBIT -Assets and expensesCREDIT- Liabilities and income
