A profit margin indicates how much profit a company makes on total sales, and what portion of its revenues which are actually profit.
A profit margin is found by dividing a company’s post-tax net profit over a financial year by its total sales over the same financial year.
An automobile manufacturer makes a net profit of 6 billion francs over a financial year. In the same year, the company’s total sales come to 35 billion francs. So the company’s profit margin is 17.14%, meaning that 17.14% of the company’s total sales revenues is actual profit.
