Method 1
Margin= Gross profit / Sales
= Gross profit / (Gross profit + Cost of good sold)
e.g.
Gross profit=$100
Cost of good sold=$50
Margin= 100/ 150= 2/3

Method 2
(Mark up= Gross profit / Cost of good sold)
e.g.
Mark up=1/5
Margin=1/(5+1)=1/6

Profit:
（毛利) Gross profit = Sales - Cost of good sold
（淨利）Net profit = Gross profit + revenues - expenses
