5. Profit margin

Definition: Operating profit as a percentage of sales (or turnover)

Significance:

Profit margin tells you about the underlying profitability of a company's trading activities, not whether it is actually making money for shareholders.

Calculation:

Multiply operating profit by 100, and divide the result by turnover

Example

M&S made an operating profit of £897m on a turnover of £6,806m.

Profit margin was therefore (897 x 100) / 6,806= 13.18%

Profit Margin:       %

Points to note:

Profit margin is calculated before taking account of interest charges or tax.

Yardstick:

Typical margins vary from one business to another, so while 15% might be good in one industry, it would be considered poor in another.
