2026 US fee guide
Amazon FBA Fees Explained (2026 Guide for Sellers)
Quick answer: Amazon FBA cost is a stack, not one percentage. A US order can include a category referral fee, a size-and-weight fulfillment fee, monthly storage, inbound and prep costs, advertising, and a 3.5% fuel and logistics surcharge on applicable FBA fulfillment fees.

What fees should an Amazon FBA seller include?
- Referral fee: a category-based percentage of the applicable sales-price base. Many categories use rates between 8% and 15%, but category minimums and tiered rates can differ.
- FBA fulfillment fee: the per-unit pick, pack, shipping, customer-service, and returns-handling charge determined by size tier, shipping weight, apparel status, and program eligibility.
- Fuel and logistics surcharge: Amazon announced a 3.5% surcharge on US and Canada FBA fulfillment fees effective April 17, 2026. It applies to the fulfillment fee, not the product selling price.
- Monthly storage: a charge based on the daily average cubic-foot volume occupied by inventory, with higher standard-size rates from October through December.
- Seller-specific costs: product cost, inbound transportation, placement-service fees, prep and labeling, advertising, returns, aged inventory, removals, and other account-specific charges.
Amazon said its January 15, 2026 US referral and FBA changes increased FBA fees by an average of $0.08 per unit and introduced no new fee types. The later fuel and logistics surcharge is a separate percentage applied to fulfillment fees.

|---|---|---|

| Small standard | 8+ to 10 oz | $3.43 |
| Small standard | 14+ to 16 oz | $3.65 |

| Large standard | 12+ to 16 oz | $4.55 |
| Large standard | 1.75+ to 2 lb | $5.77 |
| Large standard | More than 3 lb through 20 lb | $6.92 + $0.08 per 4 oz above 3 lb |

Published base-rate examples reviewed 2026-08-08. Apply the current surcharge and any account-specific services where applicable. Apparel and Low-Price FBA use different schedules.
2026 monthly storage examples
| Inventory type | January–September | October–December |
|---|---|---|
| Standard size | $0.78 per cubic foot | $2.40 per cubic foot |
| Oversize | $0.56 per cubic foot | $1.40 per cubic foot |
These are monthly storage-rate examples, not a per-unit quote. A per-unit estimate requires the packaged volume of one unit and the average time inventory remains stored. Additional storage-related charges can apply.
Amazon FBA profit formula
Estimated profit = order revenue - referral fee - FBA fulfillment fee and surcharge - storage allocation - product, inbound, prep, advertising, return, and other seller costs
Worked example: On a $30 order with a 15% referral rate, a $4.50 base fulfillment fee, the 3.5% surcharge on that fulfillment fee, $0.50 storage allocation, $8 product cost, $1 inbound cost, $0.50 prep, and $3 advertising, estimated profit is about $7.84. That is an estimated 26.1% margin before any omitted or account-specific fees.
Enter the surcharge-adjusted fulfillment amount—about $4.66 in this example—in the calculator's editable fulfillment-fee field.
Amazon FBA fee input checklist
| Input | Where to verify it | Common mistake |
|---|---|---|
| Referral fee | Amazon fee category and Revenue Calculator | Using a generic 15% rate for every category |
| Fulfillment fee and surcharge | Fee Preview or Revenue Calculator for the ASIN | Ignoring recorded dimensions, shipping weight, or the applicable surcharge |
| Storage allocation | Inventory reports plus packaged cubic volume and expected storage time | Using a monthly cubic-foot rate as though it were a per-unit fee |
| Inbound, placement, and prep | Shipment, service, and supplier invoices | Leaving costs at zero because they are billed separately |
| Advertising and returns | Ads reports, settlement data, and return history | Calculating profit before customer acquisition and expected losses |
How to estimate an ASIN accurately

- Use packaged dimensions and weight to identify the correct size tier.
- Open Amazon's Revenue Calculator or Fee Preview for the product.
- Include the applicable fulfillment surcharge and a realistic storage allocation.
- Add product, inbound, prep, advertising, return, and overhead costs.
- Compare the estimate with actual settlement and fee-preview reports after the product sells.
Frequently asked questions
Is the Amazon referral fee the same as the FBA fee?
No. The referral fee is generally category-based and tied to the sale. The FBA fulfillment fee pays for fulfillment services and depends primarily on the product's size, shipping weight, apparel status, and program.
Does every FBA product cost the same to fulfill?
No. Small packaging or weight changes can move an item into another tier. Verify the dimensions Amazon records for the ASIN rather than relying on a generic average.
Does the Seller Math Hub calculator automatically select a size tier?
No. It keeps the fulfillment and storage inputs editable so you can enter the amounts shown for your product in Amazon's own tools.
