How will Amazon’s new Fuel Surcharge impact your Net Profits?
Amazon’s announcement of a new 3.5% fuel surcharge is a whopper of a hit for Amazon sellers’ profits. It sounds expensive as a cost taken out of your top line, but it is even worse when considered in the context of a seller’s net profits.

Prior to the surcharge, there were already a number of different Amazon fee types that could be taken out of a seller’s revenue. Some of these fees are charged as standard monthly fees and others are charged on a per-item basis. That makes it hard to understand the costs associated with any given sale. Given the volumes and complexity, you may need an automated accounting software tool designed for eCommerce to get a true handle on what it’s really costing you to sell.
What does it cost to sell a $100 item on Amazon?
Here’s an illustrative example. Let’s take an Amazon seller with an item that sells for $100.
Inventory Cost
Often the largest cost of selling an item on Amazon is the inventory cost itself, what the seller had to pay in order to acquire the item. Let’s say they purchase it for $50 and are reselling it for $100 on Amazon. This $50 inventory cost is typically referred to as Cost of Goods Sold.
Monthly Amazon Fees
Sellers have to pay $39.99/month as a professional seller or $0.99 per item as an individual seller in order to sell on the platform. Let’s assume our seller is selling 100 items per month on the professional plan, so that monthly fee would work out to $0.39 per item sold.
If they are using Fulfillment by Amazon (FBA) they will also pay monthly storage fees for their inventory to be stored in Amazon’s warehouses. These fees go up if inventory has been stored too long, is oversized, or is dangerous. The fees also go up depending on the time of year when the inventory is being stored with October-December more expensive to handle the peak holiday volumes. Storage in January-September for standard goods might cost $0.78 per cubic foot of inventory stored, plus an Aged Inventory Surcharge starting at $0.50 per cubic foot for items stored longer than 180 days. If our $100 item takes up one cubic foot and has not been
stored longer than 180 days, it would cost $0.78 per month to store.
With these two monthly costs, we’re at a total of $0.39 + $0.78, or $1.17 in total monthly costs for our $100 item. For the sake of simplicity, let’s say the item was only stored for 1 month and this is our total FBA storage cost (though in many cases inventory must be stored longer than this.)
Per-Item Fees
Amazon charges a Referral Fee of anywhere from 8-17% depending on the category in which the item is sold, with a minimum $0.30 fee in most categories. Let’s assume our $100 item is something in the Toys & Games category, which is 15%. Our $100 item would cost $15 in Referral Fees.
FBA Fulfillment Fees are also charged on a per-item basis. These fees range significantly depending on the size and weight of the item as well as other factors. For the sake of simplicity, let’s say we have a “Large Standard” item and we’re paying approximately $5.50 to have Amazon fulfill this shipment for us.
FBA Fulfillment Fees are where the new 3.5% fuel surcharge fee have been added. We’ll hold that cost out for now and show how that impacts Net Profit at the end of this article.
Amazon Advertising Fees
It used to be enough to list your products on a well-established marketplace to drive sales, but in today’s world, it often requires paying advertising fees in order to generate visibility to those listings as well. Advertising on Amazon is sold on a Cost-Per-Click (CPC) basis and costs can range from $0.60 per click in a Low-Competition category to over $5.00 per click in a more competitive space. It’s not uncommon for a seller to pay an additional $15-$30 in Advertising to get a $100 item to sell, though they probably can’t be doing this across all their inventory and remain profitable.
In addition, there are overhead fees to advertising. Agencies to manage your advertising often charge 10-15% of advertising fees. For sponsored brands campaigns, things like high quality photography and ad creative development can be quite expensive.
For simplicity, let’s say advertising costs $5 all in for our $100 item.
Additional Amazon Fees
In addition to the standard fees listed above, there are many additional things Amazon charges for including Inbound Placement Fees, to move your inventory between Amazon Warehouses, Low Inventory Fees, when a high-velocity product becomes low in stock, Returns Processing Fees, Removal Order Fees, when you request your inventory is returned to you, Label Order Fees, when Amazon labels your products for you, and more. For today’s example, we won’t include any of these fees, but they are very real costs of doing business for an Amazon seller.
Net Profit, BEFORE the 3.5% Fuel Surcharge
What is net profit? It’s how much money you’ve made after all of your costs have been taken into account.
In our example of the $100 item sale, we’ve now accounted for the following fees:
$50.00 Inventory / Cost of Goods Sold
$0.39 Amazon Professional Sellers Fee
$0.78 monthly FBA Storage Fee
$15.00 Amazon Referral Fee
$5.50 FBA Fulfillment Fee
$5.00 Advertising Fees
$76.67 Costs
On our $100 sale, this is a Net Profit of $23.33.
Net Profit, AFTER the 3.5% Fuel Surcharge
If our $100 item has an additional 3.5% Fuel Surcharge, which is calculated on the full cost of the $100 sale, that would be an additional $3.50 in cost.
After the Fuel Surcharge, Net Profit is $19.83. If our seller was making $23.33 before, and now they’re only making $19.83, that is a 15% reduction in Net Profit.
Outsized impact on Net Margin
Your NET PROFIT will drop by 15% in this case
With razor thin margins and massive competition on Amazon already, this is a huge change.
How Can Sellers Understand What this Fee Change Actually Means for their Profits
This was just an illustrative example, and fees on Amazon are very complex. Each seller needs to truly understand their own economics on Amazon in order to know how significant an impact this change will have for them.
