The Amazon FBA Fee Calculator estimates total Amazon fees per unit sold through Fulfillment by Amazon: the referral fee (8–20% depending on category), the FBA fulfillment fee (size and weight based, $3.06–$10+ per unit), and monthly storage fees (per cubic foot). For arbitrage, wholesale, and private label sellers, this calculation determines whether a product is profitable before sourcing.

공식

Net Profit = Selling Price − Referral Fee − Fulfillment Fee − Storage Fee − Item Cost − Inbound Shipping

P: Selling Price (currency) — Listed Amazon retail price
Ref%: Referral Fee % (%) — Category commission: 8–20%, $0.30 minimum
FF: Fulfillment Fee (currency/unit) — Pick, pack, ship by size and weight tier
SF: Storage Fee (currency/unit) — Cubic feet × monthly rate × storage months

피해야 할 일반적인 실수

✕Forgetting that referral fees have a $0.30 minimum — low-priced items pay disproportionately more
✕Using off-peak storage rates for Q4 — October to December storage fees roughly triple ($2.40/cu ft small)
✕Ignoring long-term storage surcharges — items in FBA over 271 days incur extra fees
✕Misclassifying product size tier — items over 12" or 1 lb often qualify as Large Standard with higher fees

자주 묻는 질문

What is the minimum referral fee?

Amazon charges a $0.30 minimum referral fee regardless of category percentage. For items under $2, this minimum makes FBA unprofitable.

When do Q4 storage fees apply?

October, November, and December — typically 3× the off-peak rate. Plan inventory to minimize Q4 storage exposure unless holiday-driven sales offset the cost.

What is long-term storage fee?

Items in FBA for over 271 days incur a $6.90/cu ft surcharge applied monthly. Slow-moving inventory should be removed before crossing this threshold.
