Use these numbers to fill in the fulfillment fee field above. Two limits you need to know: (1) these are non-peak rates, effective 15 January 2026 to 14 October 2026, holiday peak rates apply from 15 October 2026 to 14 January 2027 and are higher, and the published sources we could verify disagree on the peak figures, so this page deliberately does not calculate them; (2) a 3.5% fuel and logistics surcharge has applied to fulfillment fees since 17 April 2026 and is not included in the table above, multiply by 1.035. Large standard shipping weight is the greater of unit weight and dimensional weight (× × × / 139); small standard uses unit weight only. Apparel and dangerous goods use separate rate cards.
Referral fee percentages and per-item minimums are taken from Amazon's published US “Selling on Amazon Fee Schedule” (Seller Central help pages 200336920 and G200336920) and cross-checked against Amazon's own pricing page at amazonservices.com. Rates checked 15 October 2026.
Two notes on the categories where published sources disagree:
This is an independent calculator and is not affiliated with, endorsed by, or connected to Amazon.com, Inc. Amazon and FBA are trademarks of Amazon.com, Inc. and are used here only to refer to that service. Amazon changes fees without notice, confirm the current numbers in Seller Central before you price inventory.
There is no universal figure, but referral fee plus fulfillment fee alone commonly take 25–45% of a standard-size sale, before advertising and storage. The “break-even cost of goods” line on this page tells you the most you can pay for a unit at your price before the sale turns into a loss.
Because we could not verify the current peak-season rate card to our standard. FBA fees change on 15 January, 17 April (the 3.5% surcharge) and 15 October each year, and the sources we checked disagree on the peak figures. Rather than guess, this page shows the verified non-peak table below and asks you to enter the number, or read it straight out of the Revenue Calculator in Seller Central.
No. Amazon applies the fuel and logistics surcharge to the fulfillment fee only, not to the selling price and not to the referral fee. If you take a base fee from the table below, multiply it by 1.035 before entering it.
For large standard, small bulky, large bulky and extra-large units, Amazon bills on the greater of unit weight and dimensional weight, where dimensional weight is length × width × height divided by 139 (inches, pounds). Small standard and extra-large items over 150 lb use unit weight only.
Not automatically. Add them into the fulfillment fee field if you want them in the margin, or leave them out and read the result as contribution before ad spend.
