Amazon FBA Fee Calculator

Amazon charges three stacked fees, each with a different basis, which is why a single blended margin percentage is misleading. The referral fee is a percentage of the total sale price including the shipping the buyer pays: 15 percent for most categories, 8 percent for consumer electronics and for beauty and grocery items above the category threshold, and 17 percent for clothing and accessories, subject to a 0.30 dollar per-item minimum. The fulfillment fee is a flat per-unit charge set by size tier and shipping weight, starting near 3.22 dollars for a small standard unit under four ounces and rising past six dollars near the three-pound standard boundary, with oversize tiers considerably higher; for bulky items Amazon bills dimensional weight, computed as length times width times height divided by 139. Storage is charged per cubic foot of daily average volume and is seasonal, roughly 0.78 to 0.87 dollars from January through September and about 2.40 from October through December, with aged-inventory surcharges once units pass 181 days. Taken together these typically consume 30 to 40 percent of the sale price, which is the origin of the common screening rule of landed product cost at or below 30 percent and fees near 35 percent, leaving 25 to 30 percent gross before advertising. Two caveats: this tool approximates storage from weight rather than measured cubic feet, and it excludes the 39.99 dollar monthly Professional selling plan, sponsored-product advertising, returns processing, inbound placement and low-inventory-level fees.

Amazon opened its warehouse network to outside sellers when it launched Fulfillment by Amazon in September 2006. The referral fee is older: it is the commission structure Amazon set when it opened Amazon Marketplace in November 2000, deliberately shaped like the category commissions already familiar from eBay and from consignment retail, which is why it is charged as a percentage of the sale rather than as a service fee. FBA layered a per-unit logistics charge on top of that commission, and the decisive attraction was never the warehousing itself but eligibility for Prime, launched in February 2005. Letting third-party inventory carry the Prime badge is the reason sellers accept fulfillment costs well above what independent shipping would cost them. The fee schedule has been revised repeatedly, almost always in the direction of forcing inventory turnover and pricing operational externalities. Long-term storage fees were introduced to clear warehouses of dead stock and were restructured into aged-inventory surcharges in 2023. The Small and Light program, launched in 2015 for inexpensive items, was retired in 2023 and replaced by low-price FBA rates. In 2024 Amazon added inbound placement service fees for sellers who ship to a single receiving center and low-inventory-level fees for sellers who hold too little stock, alongside the peak-season fulfillment surcharge that now recurs each fourth quarter. Because the published rate card changes at least annually, any FBA margin model has to be re-run against the current published schedule.
