Estimate your true FBA profit per unit after referral fees, fulfillment fees, and the 2026 fuel surcharge.
Amazon charges a referral fee (a percentage of your sale price, usually 8–15% depending on category) plus a fixed fulfillment fee based on your product's size tier. Since April 17, 2026, Amazon also applies a 3.5% fuel and logistics surcharge on top of all FBA fulfillment fees. Your profit is what's left after subtracting your product cost and all three fees from the sale price.
Fulfillment fees are the single biggest lever you control. A product that barely fits in a larger tier can cost you $2–5 more per unit in fulfillment fees alone — often the difference between a profitable SKU and a break-even one. Check your exact tier in Seller Central before finalizing packaging.
Say you sell a $29.99 item that costs you $8 to make, in the Large Standard tier ($4.50 fulfillment) at a 15% referral fee. Referral fee is $4.50, fulfillment is $4.50, subtotal $9.00, plus 3.5% fuel surcharge ($0.32) brings total fees to $9.32. Profit is $29.99 − $8.00 − $9.32 = $12.67, a 42.2% margin.
Are these exact fees for my product? No — referral fees range from 8% to 45% depending on category (most are 15%), and fulfillment fees depend on your exact weight and dimensions. Use Amazon's official Revenue Calculator in Seller Central for your specific SKU before pricing.
Does this include storage fees? No. Monthly and long-term storage fees are separate and depend on how much inventory you hold and for how long — this tool covers per-unit selling costs only.
What's the fuel and logistics surcharge? A 3.5% surcharge Amazon added on April 17, 2026, applied on top of FBA and Multi-Channel Fulfillment fees, in addition to the existing Q4 peak surcharge that applies October 15 through January 14.
