Referral fee rates reflect representative category figures from Amazon's official US pricing page (sell.amazon.com/pricing) as of 2026-07. Some categories are actually tiered by price point (e.g., Beauty is 8% under $10, 15% above). The FBA fulfillment fee is a manual input because an official size-tier fee table could not be confirmed. All amounts are calculated and displayed in USD ($).

What Is Amazon's Referral Fee?

The referral fee is charged on the sale price every time an item sells, and it varies by category. Representative rates include Electronics 8%, Home & Kitchen 15%, Toys & Games 15%, Books & Media 15%, Sports & Outdoors 15%, and Clothing 5% (varies by price point). Some categories are tiered by price (e.g., Beauty & Personal Care is 8% up to $10 and 15% above), so this calculator uses a representative rate per category — use "Custom" if you need an exact figure.

How the FBA Fulfillment Fee Works

The FBA fulfillment fee is based on a product's size tier and actual/dimensional weight — smaller, lighter Small Standard items cost less, while oversize items cost more. Because Amazon revises the exact size-tier fee schedule frequently and it depends on precise measurements, this calculator asks you to enter the fee manually. Get the exact figure from Amazon's Revenue Calculator in Seller Central using your product's dimensions and weight, then paste it here.

Ways to Improve Net Profit

(1) Reducing product size/weight can drop it into a lower size tier, cutting the FBA fulfillment fee. (2) Bundling multiple units into a multipack can reduce how much the flat per-unit costs weigh. (3) Long storage duration triggers long-term storage fees, so managing inventory turnover matters. (4) Selecting the correct category avoids over- or under-estimating the referral fee.

Frequently asked questions

Why does the referral fee differ by category?

Amazon sets rates by category based on competitive intensity and typical margins. Lower-margin categories like Electronics get a lower rate (8%), while most general categories run around 15%.

Why do I have to manually enter the FBA fee?

The FBA fulfillment fee is broken down by precise size and weight tiers and revised periodically by Amazon, so rather than presenting an unreliable table, this calculator asks you to enter the figure confirmed via Amazon's official Revenue Calculator.

Is the reference table official Amazon data?

No. The size-tier example table is only meant to give a rough sense of scale and is not official Amazon data. Always confirm the actual fee in Seller Central.

How is the profit margin calculated?

Net profit (sale price minus referral fee, FBA fee, and product cost) divided by the sale price. Advertising, returns, and long-term storage fees are not included.
