Amazon FBA profitability comes down to three costs: the referral fee (typically 15% of the total sales price), a per-unit fulfillment fee based on size and weight, and a per-unit storage fee. Sellers frequently underestimate the last two.
Set the fulfillment fee to match your product's size tier and Season, enter your landed cost, and see profit per unit with a break-even price.
Formula
FBA cost = 15% referral (min $0.30/unit) + fulfillment fee + storage fee
Amazon's referral fee is a percentage of the total sales price and has a per-item minimum for most categories. Fulfillment and storage fees depend on dimensions, weight and time of year, so use Amazon's fee schedule for your exact ASIN.
