Amazon FBA Profit Calculator

FBA net profit = Selling price − (Referral fee + FBA fulfillment fee + cost of goods + inbound shipping + storage + PPC advertising). Net margin is net profit divided by selling price. Example: a $25 product in the 15% referral category with a $4.60 large-standard fulfillment fee pays about $8.35 (33%) in Amazon fees alone before COGS and PPC.

Under Amazon's 2026 US FBA rate card (effective January 15, 2026), fulfillment fees are $3.45 for small standard items under 6 oz and $4.60 for large standard items up to 1 lb. Since April 17, 2026 a 3.5% fuel & logistics surcharge is added on fulfillment fees. Referral fees are 15% in most categories. Clothing and accessories are tiered by price (5% at or below $15, 10% from $15.01 to $20, 17% above $20), consumer electronics are a flat 8%, and electronics accessories are 15% of the portion up to $100 and 8% above (official 2026 US rate card, verified 2026-09-24).

Most healthy Amazon FBA products run a 15–25% net margin after all fees. Below 10% net margin a product is fragile — a single storage-fee or PPC increase can push it negative. A common benchmark is to hold at least 25–30% gross margin before advertising spend.

Amazon's referral fee is 15% of the sale price in most categories in 2026, with exceptions: clothing and accessories 17%, jewelry 20%, Amazon device accessories 45%, video game consoles 8%, and electronics 8% for items priced $100 or less. Most categories also carry a minimum referral fee between $0.30 and $1.00 per item.

Yes. Since April 17, 2026, Amazon applies a 3.5% fuel & logistics surcharge on top of FBA fulfillment fees only — it does not apply to referral fees, storage fees, or inbound placement fees. On a $4.60 large-standard fulfillment fee the surcharge adds roughly $0.16 per unit.

Standard-size storage costs $0.78 per cubic foot from January through September 2026, rising to $2.40 per cubic foot in the October–December peak season — about 2.8 times higher. Oversize storage is $0.56 low season and $1.40 peak. Inventory stored more than 181 days also pays an aged inventory surcharge of $0.50-$7.90 per cubic foot, starting at day 181 and jumping at day 271.

The five most commonly missed costs are: inbound placement fees ($0.15–$0.98 per unit depending on shipment placement), monthly and peak-season storage fees, aged inventory surcharges ($0.50-$7.90 per cubic foot from day 181), return processing fees ($1.90–$5.00 per returned unit above the category threshold), the 3.5% fuel surcharge, and the peak-season fulfilment uplift that runs 15 October 2026 – 14 January 2027 (a network-wide blended +$0.32 per unit, billed by ship date). Together these can consume 10–15% of revenue on low-priced items.

Yes. From 15 October 2026 to 14 January 2027 Amazon adds a per-unit peak-season uplift to US FBA fulfilment fees, assessed on the ship date rather than the order date — an order placed on 10 October but shipped on 20 October pays the peak rate. The uplift runs from about +$0.20 for a 2–6 oz small standard unit to +$8.51 for a 150 lb+ special oversize unit; Amazon quotes a network-wide blended average of +$0.32 per unit, which is a mix of tiers and not any single SKU's uplift. It is charged before the 3.5% fuel surcharge, so the all-in peak fee is (base + overage + peak) × 1.035 rather than base × 1.035 + peak. Rates revert on 15 January 2027. Note the peak storage window (1 October – 31 December 2026) is a different window from the peak fulfilment window, so one date cannot drive both.
