Profit Margin on an item that Cost $20 with a Selling Price of $24.20

Given: Cost = $20,  Selling Price = $24.20
Formula:
Profit Margin =  
Selling Price – Cost/ Selling Price

Profit Margin =  
$24.20 – $20/ $24.20

Profit Margin =  
$4.20/ $24.20

Profit Margin = 0.1736 = 17.36%
Notes:
Profit = Selling Price – Cost = $24.20 – $20 = $4.20
Markup Amount = Profit = $4.20
Markup Percentage =  
Markup Amount/ Cost
=  
$4.20/ $20
= 0.21 = 21%
