Typically 30–35% of the sale price on standard-size products: a referral fee (usually 15%, 8–17% by category), a fulfillment fee ($3.06–$8+ by size tier), a 3.5% fuel surcharge on that fulfillment fee, monthly storage ($0.78/cu ft, $2.40 in Q4), and inbound placement fees. The FBA calculator stacks all of them from your inputs.
Run both numbers. FBA wins on Prime eligibility and hands-off logistics; FBM wins on margin for heavy, oversized, or slow-moving products where fulfillment fees eat 30%+. Compare the Amazon profit calculator's FBA result against your own shipping costs before committing inventory.
