Frequently Asked Questions

What is Amazon's Referral Fee and how is it calculated?

The Referral Fee is Amazon's commission for selling on its marketplace, charged as a percentage of your selling price. The rate varies by category—15% for most categories is the default used here, with lower rates for Electronics (8%) and higher rates for Clothing & Accessories (17%). Amazon also applies a minimum referral fee (typically $0.30) on very low-priced items, which this calculator applies as a floor.

How does the FBA Fulfillment Fee work?

The Fulfillment Fee covers Amazon picking, packing, and shipping your product from an FBA warehouse, and it is based on the product's size tier and weight (Small Standard, Large Standard, or Oversize) rather than its price. Pick the tier that matches your product's dimensions, or enter your own fee if you already know the exact amount from Amazon's Revenue Calculator.

How is net profit calculated?

Net Profit = Selling Price − Cost of Goods − Shipping to Amazon (Inbound Cost) − Total Amazon Fees (Referral Fee + FBA Fulfillment Fee). Profit margin is then Net Profit ÷ Selling Price, shown as a percentage.

Does this include monthly storage fees or long-term storage fees?

No. Monthly storage fees, long-term storage surcharges, and removal/disposal fees depend on your inventory volume, storage duration, and time of year (Q4 rates are higher), so they are not modeled per-unit here. For a precise per-unit estimate including your actual dimensions and weight, cross-check with Amazon's official Revenue Calculator before finalizing pricing.

Amazon FBA Fees Explained: Pricing for Real Profit in 2026

Selling on Amazon through Fulfillment by Amazon (FBA) means paying two separate fee types on every unit: a Referral Fee, which is Amazon's commission for the sale, and an FBA Fulfillment Fee, which covers picking, packing, and shipping the order from an Amazon warehouse. Understanding both is essential before you commit to a price, since thin-margin products can slip into a loss once fees are factored in.

The Referral Fee is a percentage of your selling price and varies by category—most categories sit around 15%, Electronics is typically lower near 8%, and Clothing & Accessories can run higher near 17%. Amazon also applies a small minimum referral fee, commonly around $0.30, which mainly affects very low-priced items where the percentage alone would round to pennies.

The FBA Fulfillment Fee, unlike the Referral Fee, is based on your product's size tier and weight rather than its price. Small Standard items carry the lowest fee, Large Standard items cost more to pick and ship, and Oversize or bulky products carry the highest fulfillment fee. Choose the tier closest to your product's packaged dimensions, or enter your own known fee if you've already run it through Amazon's Revenue Calculator.

This free Amazon FBA Profit & Fee Calculator runs entirely in your browser—enter your selling price, cost of goods, and inbound shipping cost, pick a referral category and fulfillment tier, and see your total fees, net profit, and margin update instantly. Nothing is uploaded, so you can model new SKUs privately before committing to a price or shipment.
