The accounting equation

What is the formula for the accounting equation?

• The formula for the accounting equation is: Assets = Liabilities + Capital

• The equation states that the assets of a business are always equal to the liabilities and capital of the business

• You can rearrange the equation so that you can find one of the three values if the other two are known

  • Liabilities = Assets - Capital
  • Capital = Assets - Liabilities

The accounting equation

Exam Hint You may be given examples of assets and liabilities and asked to calculate the missing figure for capital.

Worked Example The assets and liabilities are listed below for a business.

	$
Premises	8 500
Equipment	7 000
Inventory	1 000
Trade receivables	5 000
Trade payables	4 500
Bank overdraft	1 200

Calculate the capital of the business.

Answer:

STEP 1 Calculate the total assets:

	$
Premises	8 500
Equipment	7 000
Inventory	1 000
Trade receivables	5 000
Total assets	21 500

STEP 2 Calculate the total liabilities:

	$
Trade payables	4 500
Bank overdraft	1 200
Total liabilities	5 700

STEP 3 Apply the formula Capital = Assets - Liabilities

$21 500 - $5 700 = $15 800

Why is the accounting equation important?

• The accounting equation may be shown in the form of a statement of financial position

• The statement of financial position will be affected every time the business makes changes to the assets, liabilities and capital

• Every single transaction will result in at least two changes which balance out

  • Both sides of the equation could increase by the same amount
  • Both sides of the equation could decrease by the same amount
  • Both sides of the equation could stay the same

Case Study Hannah is the owner of a business. Some of her transactions are listed below. After each transaction, the accounting equation still balances.

Transaction	Effects on assets	Effects on liabilities or capital
A credit customer, Peter, pays the amount owed to Hannah by cheque for $1 120	**Assets increase by $1 120 because the money in the bank increases Assets decrease by $1 120 because the amount owed by Peter decreases Overall no change to assets	No change in liabilities or capital
Hannah pays the amount owed to a credit supplier, Rizwan, by cheque for $4 200	**Assets decrease by $4 200 **because the money in the bank decreases	** Liabilities decrease by $4 200 because the amount owed to Rizwan decreases
Hannah buys additional fixtures and fittings for $5 500 on credit from FixFit Ltd	**Assets increase ** **by $5 500 **because the value of Hannah's assets increases	** Liabilities increase by $5 500 because the amount owed to FixFit Ltd increases
Hannah takes goods worth $500 from the business for personal use	**Assets decrease by $500 **because the amount of inventory decreases	** Capital decreases by $500 because Hannah takes drawings from the business
Hannah transfers $1 000 from her personal bank account into the business bank account	**Assets increase by $1 000 **because the money in the bank increases	** Capital increases by $1 000 **because Hannah invests $1 000 into the business
Hannah makes $20 profit by selling goods which cost $30 for $50 cash	**Assets increase by $50 because the amount of cash increases Assets decrease by $30 **because the amount of inventory decreases **Overall assets increase by $20 **	** Capital increases by $20 because a profit has been made

Worked Example A business pays one of its trade payables by cheque. Identify the effects on the business' assets and liabilities.

	**Effect on assets **	Effect on liabilities
A	Reduce bank	Reduce trade payables
B	Increase bank	Increase trade payables
C	Reduce trade payables	Reduce bank
D	Increase trade payables	Increase bank

Answer:

Money in the bank is an** asset** and trade payables is a liability. A payment made by cheque would reduce the money in the bank, therefore reducing the asset. Trade payable is a liability. The business debt would be reduced when payment is made.

Final answer: The answer is A.
