Amazon charges a US FBA fulfillment fee on every unit it picks, packs and ships for you. For a standard-size, non-apparel item the fee runs from $3.06 for a unit of 2 oz or less to $6.92 for a unit of 3 lb, and it rises with shipping weight. Storage is billed separately each month by cubic foot. This guide shows the numbers Amazon lists, how to read them, and how to put them into a margin check before you order stock.
The figures below come from the FBA costs section of Amazon's own page at sell.amazon.com/fulfillment-by-amazon, read on 4 November 2026. The page shows no effective date, and Amazon revises fees regularly, so confirm the current rate card in Seller Central before you commit to an order.
What the FBA fulfillment fee covers
The fulfillment fee pays for picking, packing, shipping and customer service on each order. It is charged per unit sold, on top of the referral fee. Amazon sets it by product size tier and shipping weight, and there are separate tables for apparel and non-apparel. If you are still working out the full stack of costs, see how to calculate Amazon FBA profit in the US, UK and Germany and Amazon referral fees by category.
Standard-size fees for non-apparel (US)
Small standard, by shipping weight:
| Shipping weight | Fee per unit |
|---|---|
| 2 oz or less | $3.06 |
| 2 to 4 oz | $3.15 |
| 4 to 6 oz | $3.24 |
| 6 to 8 oz | $3.33 |
| 8 to 10 oz | $3.43 |
| 10 to 12 oz | $3.53 |
| 12 to 14 oz | $3.60 |
| 14 to 16 oz | $3.65 |
Large standard, by shipping weight:
| Shipping weight | Fee per unit |
|---|---|
| 4 oz or less | $3.68 |
| 4 to 8 oz | $3.90 |
| 8 to 12 oz | $4.15 |
| 12 to 16 oz | $4.55 |
| 1 to 1.25 lb | $4.99 |
| 1.25 to 1.5 lb | $5.37 |
| 1.5 to 1.75 lb | $5.52 |
| 1.75 to 2 lb | $5.77 |
| 2 to 2.25 lb | $5.87 |
| 2.25 to 2.5 lb | $6.05 |
| 2.5 to 2.75 lb | $6.21 |
| 2.75 to 3 lb | $6.62 |
| Over 3 lb up to 20 lb | $6.92 plus $0.08 per 4 oz above the first 3 lb |
Apparel has its own, slightly higher table. For example, a small standard apparel item of 4 oz or less is $3.27, and a large standard apparel item of 1 to 1.5 lb is $5.90. Amazon also lists a Low-Price FBA table for cheaper items, starting at $2.29 for small standard non-apparel units, so check whether your selling price qualifies.
Oversize fees
Oversize items cost much more to fulfil. Amazon lists large bulky units of up to 50 lb at $9.61 plus $0.38 per pound interval above the first pound, and extra-large units of up to 50 lb at $26.33 plus $0.38 per pound interval. Heavier extra-large tiers start at $40.12 (over 50 lb to 70 lb), $54.81 (over 70 lb to 150 lb) and $194.95 (over 150 lb). If your product is bulky and cheap, the fee alone can erase the margin.
Monthly storage fees
Amazon bills inventory storage by the cubic foot, and the rate jumps in the fourth quarter.
| Size | January to September | October to December |
|---|---|---|
| Standard size | $0.78 per cubic foot | $2.40 per cubic foot |
| Oversize | $0.56 per cubic foot | $1.40 per cubic foot |
Items that sit in a fulfillment center for more than 181 days attract a monthly aged inventory surcharge. Amazon's page does not give the amount, so check Seller Central. Extra storage costs can also apply to dangerous goods and to sellers holding a lot of inventory compared with recent weekly sales. Inbound placement costs are shown per option when you create a shipping plan.
Worked example: a 10 oz kitchen gadget
Assume a large standard, non-apparel product with a shipping weight of 10 oz, sold at $24.99 in Home and Kitchen. The referral fee in that category is 15% with a $0.30 minimum, as shown on Amazon's pricing page. These landed cost and storage inputs are illustrative assumptions, not benchmarks.
| Line | Amount |
|---|---|
| Selling price | $24.99 |
| Referral fee (15%) | $3.75 |
| FBA fulfillment fee (8 to 12 oz, large standard) | $4.15 |
| Landed cost per unit (assumed) | $7.00 |
| Storage per unit (assumed 0.05 cu ft at $0.78, about 3 months) | about $0.12 |
| Remaining before ads and returns | about $9.97 |
That is a 40% margin before advertising and returns. If you spend $4 per sale on ads, you keep about $5.97. Now suppose the same item ships heavier at 1.5 lb. The fulfillment fee becomes $5.37, so you lose another $1.22 per unit just from packaging weight. Trimming an ounce off the shipping weight can be a real margin lever.
How to lower your FBA fees
Check the shipping weight Amazon uses, not just the product weight, because packaging counts. Test a slimmer pack to drop a weight band. Avoid sending in more units than you will sell within about 90 days, and plan for the October to December storage jump. Remove or liquidate stock before it passes 181 days.
Where Ecomtoro fits
Fees only matter next to demand and competition. Ecomtoro helps you research a product and sanity check its margin before you order, so a heavy, low-priced idea gets caught early.
Frequently asked questions
How much is the Amazon FBA fulfillment fee?
For standard-size non-apparel items in the US, Amazon lists fees from $3.06 for 2 oz or less up to $6.92 for 3 lb, with $0.08 added per extra 4 oz above that. Oversize items start at $9.61. Always check the current rate card in Seller Central.
Is the FBA fee charged on top of the referral fee?
Yes. The referral fee is a percentage of the sale price, and the fulfillment fee is a per-unit amount based on size and weight. You pay both on each FBA sale, plus storage.
When does Amazon charge more for storage?
Standard-size storage is $0.78 per cubic foot from January to September and $2.40 per cubic foot from October to December, according to Amazon's FBA page. Aged inventory in the warehouse for more than 181 days incurs a monthly surcharge.
Is apparel more expensive to fulfil?
Slightly, in most weight bands. A small standard apparel item of 4 oz or less is listed at $3.27, while a small standard non-apparel item of 2 oz or less is $3.06 and one of 4 to 6 oz is $3.24. Apparel also uses its own weight bands, so compare the exact tier before you decide.
