Profit Margin on an item that Cost $100 with a Selling Price of $140

Given: Cost = $100,  Selling Price = $140
Formula:
Profit Margin =  
Selling Price – Cost/ Selling Price

Profit Margin =  
$140 – $100/ $140

Profit Margin =  
$40/ $140

Profit Margin = 0.2857 = 28.57%
Notes:
Profit = Selling Price – Cost = $140 – $100 = $40
Markup Amount = Profit = $40
Markup Percentage =  
Markup Amount/ Cost
=  
$40/ $100
= 0.4 = 40%
