The Double Entry System

What is the double entry system?

  • The double entry system is used by bookkeepers 

    • The double entry system is used to improve the accuracy of financial statements

  • The double entry system is closely linked to the accounting equation

    • Assets = Liabilities + Equity

  • The equation is always balanced

  • Each transaction causes both sides of the equation to:

    • increase

    • or decrease

    • or remain the same

  • Each transaction is entered into two accounts

    • One is called a debit entry

    • One is called a credit entry

What is the layout of a ledger account?

  • Each account will be split into two sides

    • The debit entries appear on the left

      • This side is sometimes labelled as Dr

    • The credit entries appear on the right

      • This side is sometimes labelled as Cr

  • When you make an entry you need to include:

    • The date of the transaction

    • The details of the transaction

      • This is normally the name of the other account involved

    • The value of the transaction

How do I decide whether an account should be debited or credited?

  • STEP 1
    Identify the asset, liability or equity

    • Usually this is cash, trade receivables or trade payables

  • STEP 2
    Determine whether its value is increasing or decreasing

  • STEP 3
    Debit or credit that account

    • Debit the account if:

      • It is an asset account and its value is increasing

      • It is a liability or the equity account and its value is decreasing

    • Credit the account if:

      • It is an asset account and its value is decreasing

      • It is a liability or the equity account and its value is increasing

  • STEP 4
    Put an equal entry on the opposite side for the second account

A debit entry is used to increase an asset or decrease a liability. A credit entry is used to increase a liability or decrease an asset.
Debit and credit entries achieve specific purposes depending on the type of account

Do I debit or credit accounts for expenses & incomes?

  • When you pay an expense you will debit that account

    • This is because expenses decrease the profit

      • The equity will decrease

    • The other part of the double entry is to credit the cash or bank account

      • Your cash is decreasing

  • When you receive an income you will credit that account

    • This is because income increases the profit

      • The equity will increase

    • The other part of the double entry is to debit the cash or bank account

      • Your cash is increasing

Do I debit or credit accounts for drawings & capital?

  • When the owner takes out money or goods from the business for themselves you will debit the drawings account

    • This is because taking drawings decreases the equity

    • The other part of the double entry is to credit the cash or bank account

      • The company’s cash is decreasing

  • When the owner adds their own money to the business you will credit the capital account

    • This is because introducing money increases the equity

    • The other part of the double entry is to debit the cash or bank account

      • The company’s cash is increasing

Examiner Tips and Tricks

To remember which side of an account to record a transaction, you can use the acronym DEAD CLIC.

  • The transaction is on the debit side for expense, asset, and drawings accounts if the account is increasing.

  • The transaction is on the credit side for liability, income, and capital (equity) accounts if the account is increasing.

  • If the account is decreasing then the transaction is recorded on the opposite side!

DEAD CLIC can be used to determine whether to debit or credit an account.
