Amazon Raises Fulfillment Fees Twice, Yet the Median Platform Fee Remains Around 40%

According to a quarterly report by third-party tool provider Seller Assistant, after Amazon raised fulfillment fees twice in four months in 2026, the median share of product selling prices taken up by platform fees remained broadly stable at around 40%. For sellers, the simultaneous rise in fees and stability in the fee share means that assessing business pressures requires looking at both the actual fee amounts and fees as a proportion of selling prices.

These two metrics are not contradictory. Higher fulfillment fees reflect changes in charges, while the fee share is affected by both the fee amount and the product selling price. Therefore, a broadly stable share does not mean that sellers’ expenses have not increased, nor does it establish that price increases have been offset by sales revenue growth. The report’s overall findings are also insufficient to explain the specific reasons why this proportion remained stable.

A median of around 40% offers a reference point for assessing the burden of platform fees, but it does not mean that every product or seller is at the same level. This metric describes platform fees as a proportion of the selling price; it is not equivalent to an individual commission rate, and the remainder should not be considered the seller’s profit.

The impact of higher fulfillment fees on profits still depends on the selling price of each product, other costs, and the existing profit margin. If the selling price and other costs remain unchanged, the additional fulfillment fees will reduce profit per unit. Products with narrower profit margins are generally more sensitive to an increase of the same amount.

The more useful focus now is how actual charges and profits for specific products have changed following the fee adjustments. To determine whether sellers have absorbed the additional costs, it will also be necessary to consider changes in selling prices and the ongoing trend in fees as a proportion of those prices. The stability of the median share of platform fees alone is not enough to conclude that sellers’ profitability has remained stable.
