Enter your fulfillment feeAmazon publishes its 2026 per-weight FBA fulfillment fee table only inside Seller Central, which requires a seller sign-in, so we do not copy it from third-party sites. Enter the fee Amazon shows for your product (in the fee preview, the Revenue Calculator or the "FBA fulfillment fees" help page[7]); the calculator adds the 3.5% surcharge and every other fee from Amazon's public pages.
Amazon FBA fees in 2026
An FBA sale carries four Amazon charges: the referral fee, the fulfillment fee, the fuel and logistics surcharge on that fee, and monthly storage while the unit waits to sell.[1][3]
| Fee | Amount | Notes |
|---|---|---|
| Referral fee | 8% to 20% by category (15% for most) | On the total price; minimum $0.30 per item in most categories |
| Fulfillment fee | Per unit, by size tier and shipping weight | Peak rates from October 15, 2026 to January 14, 2027 |
| Fuel and logistics surcharge | 3.5% of the fulfillment fee | Since April 17, 2026 |
| Monthly storage | $0.78/cu ft (Jan–Sep), $2.4 (Oct–Dec), standard size | Oversize: $0.56 and $1.4 |
| Selling plan | $39.99/month Professional, or $0.99 per item Individual |
Holiday peak fulfillment fees run from October 15, 2026 to January 14, 2027 and average $0.32 more per unit, with the surcharge on top.[4] Other FBA fees, such as inbound placement, low-inventory-level, aged-inventory and returns processing fees, depend on your account and are not in the calculator.
FBA size tiers
Amazon sorts every product into a size tier by its packaged dimensions and weight; the tier sets the fulfillment fee band and the storage rate.[2]
| Size tier | Max weight | Longest side | Median side | Shortest side | Length + girth |
|---|---|---|---|---|---|
| Small standard | 16 oz | 15 in | 12 in | 0.75 in | — |
| Large standard | 20 lb | 18 in | 14 in | 8 in | — |
| Small bulky | 50 lb | 37 in | 28 in | 20 in | 130 in |
| Large bulky | 50 lb | 59 in | 33 in | 33 in | 130 in |
| Extra-large | over 50 lb | over 59 in | over 33 in | over 33 in | over 130 in |
Length plus girth is the longest side plus twice the sum of the other two. The calculator places your product with these limits and its unit weight; Amazon also compares a dimensional weight for most tiers when it sets the fulfillment fee, which is one reason to use the fee Seller Central shows.
Amazon FBA storage fees by month
Storage is charged per cubic foot per month on the average daily units you store, and it triples for standard-size items from October to December.[2]
| Size | January–September | October–December |
|---|---|---|
| Small and large standard | $0.78 per cu ft | $2.40 per cu ft |
| Small bulky, large bulky, extra-large | $0.56 per cu ft | $1.40 per cu ft |
A 10 × 7 × 3 inch box is 0.122 cubic feet, so a month of storage costs $0.09 from January to September and $0.29 in the holiday quarter. Slow sellers pay it every month they sit.
FBA profit calculator table: price needed for $5 profit per unit
To clear $5 a unit through FBA, the price has to cover the product cost, the fulfillment fee with its 3.5% surcharge and the $5, and then about 18% more for the 15% referral fee: a $10 product with a $5.50 fulfillment fee needs $24.34. Each cell is the lowest price that leaves $5 of profit after all FBA fees, using the home and kitchen referral rate and no storage.[1][3]
| Fulfillment fee | $5 cost | $10 cost | $15 cost |
|---|---|---|---|
| $3.50 | $16.02 | $21.90 | $27.79 |
| $4.50 | $17.25 | $23.13 | $29.01 |
| $5.50 | $18.46 | $24.34 | $30.22 |
| $7.00 | $20.29 | $26.18 | $32.06 |
Find your fulfillment fee in Seller Central, then read across. If the price your competitors charge is below the cell, the product cannot make $5 through FBA at that cost; the calculator's What to charge mode solves the exact price for any profit target.
What slow inventory costs in storage
Storage is small per unit for fast sellers but grows every month a unit sits: a shoe box that waits six months costs $1.90 at the January–September rate, and a single October–December quarter costs $2.92 because the holiday rate is about three times higher.[2]
| Package | Cubic feet | 1 month (Jan–Sep) | 6 months (Jan–Sep) | Oct–Dec quarter |
|---|---|---|---|---|
| Phone case box, 8 × 5 × 1 in | 0.023 | $0.02 | $0.11 | $0.17 |
| Example box, 10 × 7 × 3 in | 0.122 | $0.09 | $0.57 | $0.87 |
| Shoe box, 14 × 10 × 5 in | 0.405 | $0.32 | $1.90 | $2.92 |
| Small appliance, 18 × 14 × 8 in | 1.167 | $0.91 | $5.46 | $8.40 |
Enter the months you expect a unit to wait in the calculator's storage field to include it in the profit. From February 1, 2027 Amazon is folding the aged inventory surcharge into an age-based storage rate, so long-stored units will cost more per month than this table shows.[6]

A referral fee (15% in most categories), a per-unit fulfillment fee set by size tier and weight, a 3.5% surcharge on that fee, and monthly storage. On a $29.99 item with a $5.50 fulfillment fee, they total about $10.28.
What is the Amazon FBA fuel surcharge?
Since April 17, 2026, Amazon adds 3.5% to FBA fulfillment fees. It is calculated on the fulfillment fee, not on the sale price.

Cubic feet of your packaged units × the monthly rate for the size tier and season. Standard-size items cost $0.78 per cubic foot a month from January to September and $2.40 from October to December.
Why do I have to enter the fulfillment fee?
