Profit tells you how much a business made. Profit margins tell you how good it is at turning sales into profit.

Gross and net profit

Gross profit = sales revenue − cost of sales
Cost of sales is the direct cost of the goods sold, such as stock bought.
Net profit = gross profit − other operating expenses and interest
Other expenses include rent, salaries and advertising.

Margins

Gross profit margin (%) = gross profit ÷ sales revenue × 100
Net profit margin (%) = net profit ÷ sales revenue × 100
A higher margin means more of each £1 of sales is kept as profit.

Interpreting margins

Compare margins with previous years and with competitors.
A falling gross margin may mean cost of sales is rising or prices are being cut.
A big gap between gross and net margin means high other expenses.
Worked example

Revenue £50 000, cost of sales £20 000, other expenses and interest £18 000. Find the net profit margin.

  1. Gross profit = 50 000 − 20 000 = £30 000
  2. Net profit = 30 000 − 18 000 = £12 000
  3. Net margin = 12 000 ÷ 50 000 × 100

Answer: 24%

Key idea

Gross profit = revenue − cost of sales. Net profit = gross profit − other operating expenses and interest. Margin = profit ÷ revenue × 100. Compare margins over time and with rivals.
