Landed cost
?
Your true cost to get one unit into Amazon's warehouse: COGS + shipping + import duties. This is what you actually spend before Amazon touches anything. Most sellers only track COGS and get blindsided by the rest.

Amazon fees / unit
?
Combined total of Amazon's referral fee (% of selling price) + FBA fulfillment fee (based on size and weight). This is what Amazon takes per sale before you see a cent.
$0.00
PPC / sale
?
Your Amazon advertising spend per unit sold. Rule of thumb is $25/unit for new product launches. This is the cost most gurus leave out of their profit screenshots.
