Profit Margin on an item that Cost $40 with a Selling Price of $70

Given: Cost = $40,  Selling Price = $70
Formula:
Profit Margin =  
Selling Price – Cost/ Selling Price

Profit Margin =  
$70 – $40/ $70

Profit Margin =  
$30/ $70

Profit Margin = 0.4286 = 42.86%
Notes:
Profit = Selling Price – Cost = $70 – $40 = $30
Markup Amount = Profit = $30
Markup Percentage =  
Markup Amount/ Cost
=  
$30/ $40
= 0.75 = 75%
