Amazon FBA fulfillment fees in 2026 range from $3.11 to $6.97 per unit, depending on product size and weight. Small Standard items (≤2oz) cost $3.11, while Large Standard items (≤2lb) range from $3.73 to $5.82. Oversized items over 2lb start at $5.92 and increase by $0.08 per additional 4oz. These fees cover picking, packing, and shipping — and are separate from referral fees (typically 15% of sale price) and storage fees. For a 6oz product, total FBA cost per unit can reach approximately $5.59 when including referral and storage fees.
The FBA fulfillment fee is Amazon’s charge for handling your product from the moment it arrives at their warehouse until it’s delivered to the customer. This includes receiving, storing, picking, packing, labeling, and shipping your item. The fee is determined by the product’s dimensions and weight after packaging, not by its value or category. Amazon categorizes items into size tiers — Small Standard, Large Standard, Oversized, and Special Oversized — each with its own rate structure. Fulfillment fees are the largest single component of your total FBA cost, often exceeding referral fees for low-margin products. Understanding these tiers is critical to pricing your products profitably.
Amazon updated its fulfillment fee structure on April 17, 2026, consolidating tiers and adjusting rates to reflect rising logistics costs. Below is the complete 2026 rate card for standard items in the United States.
| Size Tier | Max Dimensions (in) | Max Weight (lb) | Fee Range (USD) |
|---|---|---|---|
| Small Standard | ≤15 × 10 × 0.75 | ≤2 | $3.11 – $3.70 |
| Large Standard | ≤18 × 14 × 8 | ≤2 | $3.73 – $5.82 |
| Oversized | ≤18 × 14 × 8 | 2.01 – 3 | $5.92 – $6.97 + $0.08 per 4oz over 2lb |
| Special Oversized | ≥18 × 14 × 8 or >3lb | 3.01 – 15 | $10.50 – $15.20 + $0.08 per 4oz over 2lb |
Small Standard items are further broken into 8 weight tiers based on 2oz increments, with fees increasing incrementally from $3.11 (≤2oz) to $3.70 (≤16oz). Large Standard items follow a similar 8-tier structure, ranging from $3.73 (≤1lb) to $5.82 (≤2lb). Items over 2lb are charged a base rate of $5.92 and then $0.08 for every additional 4oz. Special Oversized items (over 15lb) have fixed base rates and are subject to additional handling fees.
Amazon determines your product’s size tier based on its dimensions and weight after packaging — including all padding, labels, and inserts. The system uses the greater of the actual weight or dimensional weight (calculated as length × width × height ÷ 139). For example, a lightweight but bulky item may be classified as Oversized even if it weighs less than 2lb. This is why many sellers optimize packaging: reducing box size can drop a product from Large Standard to Small Standard, saving up to $2.71 per unit. Always measure your packaged product, not just the item itself. Amazon’s system automatically calculates this during inbound shipment processing, but you can preview your tier using the FBA Product Size Calculator in Seller Central.
Let’s calculate the total FBA cost for a product that weighs 6oz and measures 10 × 6 × 2 inches, sold for $15.00.
Even though the fulfillment fee is only $3.29, the referral fee nearly doubles the cost. This is why sellers must model total cost, not just fulfillment. If this product sells 1,000 units monthly, total FBA costs are $5,550 — not $3,290. Always include referral and storage in your profit calculations.
On April 17, 2026, Amazon simplified its fulfillment fee structure by merging several outdated tiers and adjusting pricing to reflect current carrier costs. The most significant change was the consolidation of Small Standard tiers from 12 to 8, reducing complexity for sellers. Large Standard items saw a 3–5% average increase, while Oversized items received a slight reduction in base rates to encourage bulk shipping. Amazon also extended temporary fee discounts for apparel and footwear, which remain at the lowest Small Standard rate even if they exceed 16oz. These changes were designed to reduce administrative overhead and align with inflation-adjusted shipping costs. Sellers should review their product classifications in Seller Central to ensure they’re not being misclassified under the new rules.
Reducing fulfillment fees is one of the most effective ways to improve your FBA margins. Here are proven strategies:
One seller reduced their average fulfillment fee from $4.82 to $3.41 per unit by switching from 12oz to 8oz packaging — a 29% reduction in fulfillment cost alone.
The cheapest FBA fulfillment tier is Small Standard Size, for items ≤2oz, priced at $3.11 per unit.
Yes, oversized items cost significantly more. Items over 2lb fall into the Oversized tier, starting at $5.92 and increasing by $0.08 per additional 4oz. Items over 15lb may incur additional handling fees.
Amazon updated FBA fulfillment fees on April 17, 2026, consolidating size tiers and adjusting rates for Small and Large Standard items to reflect current logistics costs.
