Q. Methods for evaluating the performance of divisions?
Profit based methods for evaluating the performance of divisions
Operating profit (net profit) margin  
=           (Profit before interest and tax (PBIT)/ Turnover)x 100% 
Gross profit (sales) margin  
   =            (Turnover less cost of sales (gross profit)/ Turnover)   x 100%                
Generally the gross profit or sales margin can also be referred to as the contribution to sales (C/S) ratio e.g. gross profit (sales less variable cost) ÷ sales.                
Mark up 
        =          (Turnover less cost of sales (gross profit) / Cost of sales) x 100%          
Controllable profit 
The controllability principle indicated that a manager should not be assessed on costs which are not within their own control.
