2.2 Income and Expenditure

  • Profit means making more money than you spend.
  • Profit is calculated by taking the difference between its income and expenditure.
  • However, the costs involved before you can sell the product is also important.
  • The cost may include more than just the purchase or production cost of an item.
    A retailer may buy products and then ship them to a warehouse where they have to be prepared
    for sale. All these steps add to the cost of an item.
  • The costs may be divided into variable and fixed expenses.
  • Fixed expenses:
    ✓ Costs that remain constant over time
    ✓ For example: rent, salaries, security, insurance, rates and taxes, etc.
  • Variable expenses:
    ✓ Depend on the production level, as the production volume goes up, so will the costs
    ✓ For example: commissions, material costs, water and electricity, petrol etc.
  • Income may also be divided into fixed and variable
  • Fixed Income
    ✓ Fixed income is money that is definite on a monthly basis.
    ✓ For example: salary received monthly
  • Variable income
    ✓ Variable income changes from month to month and is
    ✓ It is irregular and often unexpected
    ✓ For example: royalties, dividends
  • Profit Margin
    ✓ Profit margin is the percentage of the final selling price that is profit.
    ✓ Profit = Selling price – cost price
    ✓ to calculate profit margin we use the formula:


✓ The profit margin is a better indication of how well a product or company is doing.
✓ For example: Consider the following 2 scenarios to establish a better company:

  • Company A has an income of R1 400 000 and costs of R600 000.
  • Company B has an income of R200 000 and costs of R50 000.
