What is the cost per item price?
The cost per item is how much it costs you for the product or variant. For example, if you resell a product, then you can enter the price that you paid the manufacturer, excluding taxes, shipping, or other costs. Real-life example :- if your are selling a phone cover then actual phone cover price $5 (Manufacture) + Shipping cost $1 = 6$ cost per item price and your selling it on $10 so you make $4 Profit.
Formula= ([price - cost] / price) * 100) Price of item = $10 Manufacturing Cost = $6 total margin = ( ( 10 - 6 ) / 10 ) X 100 ) = 40% your profit (Margin).
