That $15.04 picture is a home-category, average-ad-spend story. Switch to beauty at $25 and referral steps through its tier; switch to apparel and the returns line roughly triples; switch to consumer electronics and referral drops to 8%. The stack's shape is always your category and your box — not Amazon's mood.
For UK, German and other non-US listings, the built-in card does not apply yet — enter those marketplaces' fulfillment and referral rates manually against your own schedule. The line structure stays identical; only the numbers change. Launch pricing is then arithmetic: stack these lines, subtract cost, and ship only if what remains sits near 20–30%.
Enter your price, cost, category and dimensions — the calculator rebuilds this exact breakdown for your SKU and solves the break-even price:
On a typical $30 home product, Amazon's platform fees plus normal operating costs stack to about $15.04 — roughly half the price. The platform lines are referral $4.50 (15%), fulfillment $4.20, fuel surcharge $0.15 (3.5%), storage $0.04 and placement $0.30; advertising $3.00 and inbound freight $1.50 are your own operating costs. Subtract the $8 item cost and the unit nets $6.96, a 23.2% margin.
