Frequently Asked Questions
Does this calculator estimate referral and FBA fees?
Yes. The estimate includes a modeled referral fee based on category and selling price, plus FBA fulfillment using your package dimensions, unit weight, fee class, and selling price band.
Why can actual profit differ?
Real payouts can change because of storage fees, returns, coupons, advertising, taxes, remeasurement by Amazon, and fee updates. This page focuses on referral and core fulfillment plus the costs you enter.
Can packaging dimensions affect the estimate?
Yes. Length, width, height, and weight drive size tier and shipping weight, which affect the modeled FBA fee. See the Amazon FBA packaging optimization guide for packaging decisions that may lower fees.
