How Much Does Amazon FBA Cost?
Amazon FBA is convenient, but the fees are some of the most complex in ecommerce — and they often add up to 30–45% of your selling price. Here's every fee broken down, with 2026 rates.
The four main FBA fees
Referral fee — Amazon's commission on each sale.
FBA fulfillment fee — a per-unit charge for picking, packing, and shipping.
Storage fees — monthly rent for the space your inventory occupies.
Professional selling plan — $39.99/month if you sell more than ~40 items a month.
Referral fee
Most categories pay 15% of the total sale price, with a $0.30 minimum per item. Rates range from about 8% (some electronics and grocery) up to roughly 20% (jewelry). This is charged on every sale regardless of how you fulfill it.
FBA fulfillment fee
This is a flat per-unit fee based on your product's size and weight — not its price. In 2026 it starts around $3.30 for small standard items, roughly $4.98 for large standard, and climbs steeply for oversize products. Fees rose by an average of $0.08 per unit on January 15, 2026, and a fuel surcharge of about 3.5% of the fulfillment fee was added in April 2026.
Storage fees
Amazon charges monthly for the space your inventory uses — around $0.75 per cubic foot from January to September, jumping to about $2.40 per cubic foot in the October–December peak. Inventory sitting longer than 365 days also incurs a long-term storage fee (about $6.90 per cubic foot).
The fees that catch sellers out
Inbound placement fees when Amazon distributes your stock across warehouses.
A low-inventory-level fee if your stock runs thin relative to sales.
Aged-inventory surcharges on slow-moving stock.
Returns processing fees in some categories.
These are easy to miss because they show up buried in settlement reports, not at the point of sale.
A worked example
You sell an item for $29.99 that costs you $7.00, plus $1.00 inbound shipping per unit.
Referral fee (15%): $4.50. FBA fulfillment fee (large standard): $4.98. Total Amazon fees: $9.48.
Profit after all costs: $29.99 − $7.00 − $1.00 − $9.48 = $12.51 (about a 42% margin). Use the calculator to run your own product through the same math.
How to keep FBA fees down
Optimize packaging and size — fulfillment fees are driven by dimensions and weight.
Keep inventory lean to avoid storage and aged-inventory surcharges, especially in Q4.
Use Amazon's optimized inbound shipment splits to reduce or avoid placement fees.
Price with all fees in mind, and recalculate whenever you run a discount.
Always check current rates
Amazon updates its fee schedule every year (most recently January 15, 2026) and the exact fulfillment fee depends on your specific product. Always confirm your current rates in Amazon Seller Central before pricing — and run the numbers through the Amazon FBA Profit Calculator.
