You sell a small-standard widget for $29.99 with a $8.00 landed cost. Amazon takes a $4.50 referral fee (15%) plus a $3.22 FBA fulfillment fee, totalling $7.72. After cost and fees your net profit is $14.27, a 47.6% margin. Swap the category to consumer electronics (8%) and the referral drops to $2.40, lifting net profit to $16.37 and margin to 54.6%.
takeaway, Category selection alone can swing your Amazon margin by 7+ points, verify your BROWSE_NODE before listing.
