Amazon FBA Fees Explained (2026)
Amazon FBA fees are the difference between a product that looks profitable and one that actually is. They stack up in layers, and missing any layer is how sellers end up buying inventory that loses money. Here is what each fee is and how to factor it in.
The referral fee (a cut of every sale)
Amazon takes a referral feeon each sale, a percentage of the total sale price set by category. Most categories sit at 15%, with some lower, plus a small per-item minimum. This applies whether you ship the order yourself or use FBA, so it's the first thing to subtract from any sale price.
The fulfillment fee (pick, pack, and ship)
If you use Fulfillment by Amazon, the fulfillment feeis a flat per-unit charge for Amazon storing, picking, packing, and shipping the order. It's set by the product's size tier and weight, so dimensions and weight, not just price, decide your cost. A light, small item costs far less to fulfill than a bulky one.
Storage and the costs that creep in
On top of the two big fees, FBA sellers pay monthly storage fees (higher in the Q4 peak), and can incur long-term storage fees on stock that lingers, returns processing, and removal fees. These are easy to forget because they don't appear on a single sale, but they erode margin across your inventory.
The costs Amazon doesn't charge, but you still pay
Your real cost isn't just Amazon's fees. To get a true landed costyou also need prep (labelling, polybagging, or a 3PL's fee), inbound shipping to Amazon, VAT if you're registered, and a realistic returns allowance. Only after all of these do you know your true net profit and ROI.
Putting it together
For a single product, the free Amazon FBA Calculator estimates the referral and size-tier fulfillment fees so you can see net profit fast. For a whole supplier or scan list, Gridwinnerrolls those fees together with prep, shipping, and VAT for every line, so the ROI on screen is the ROI you'll keep.
