FBA Fees + Tips to Improve Profits
As with anything you invest your money into, there are fees and costs associated with selling on Amazon.
These expenses may seem like no big deal, but some fees can add up quickly and lead to overspending
issues that impact your
For example, storing excess inventory in Amazon’s FBA warehouses comes with long-term storage fees on
your standard storage fees.
And when a product is no longer selling and you need to remove the inventory from FBA, that can also
chunk out of your budget.
Amazon charges removal fees starting at $0.32 per unit all the way up to and beyond $7.70 per unit
on shipping weight and size
Understanding the fees you pay and how they affect your profit margins is one of the most important
aspects of selling on Amazon.
Many sellers operate at a loss because they don’t know how much each product really costs them when
said and done. Thus, they’re
unable to price it correctly, look for better logistics and fulfillment alternatives, and control and
In this post, we'll take a closer look at Amazon FBA fees.
We've also created a free FBA calculator that you can use to run your profit calculations.
What are Amazon FBA Fees?
The costs involved in selling on Amazon using Fulfilled by Amazon are generally referred to as FBA fees.
These fees are typically made up
of four parts:
Sellers pay Amazon a referral fee on each item sold. It’s usually 15% of the item's retail price, though
certain sub-categories have
higher or lower referral fee percentages, such as:
Amazon Device Accessories - 45%
Amazon Explore - 30% for Experiences
3D Printed Products - 12%
Video Game Consoles - 8%
Variable Closing Fee
While all Amazon sellers are charged the referral fee, an additional closing fee of $1.80 per unit sold
charged for sellers of items in
the following categories:
Software and Computer/Video Games
Video Game Consoles
Video Game Accessories
For example, when a DVD is sold, the seller is charged a $1.80 closing fee in addition to any other
Amazon Selling Plan Fees
Amazon offers two types of selling plans to new sellers:
Individual - This option is ideal for sellers that plan on selling less than 40 items per month.
Professional - Suitable for sellers who plan on selling more than 40 items per month.
The individual seller plan comes with a $0.99 fee per item sold while the professional seller plan comes
with a $39.99 monthly
subscription fee, irrespective of the number of items you sell. Suppose you're an individual seller plan
user and sold 45 items in a
month. In that case, you’ll have to pay $44.55 (45 x $0.99) in Amazon seller fees, costing you $4.56
than you would have to pay had
you selected the professional selling plan.
FBA fees include storage (monthly and long-term), removal or disposal orders, returns, and fulfillment
costs, which may vary depending on
estimated volume, time of year, and item size.
Amazon determines the estimated volume of an item by calculating its unit and carton dimensions. That’s
you must package and send your
products to Amazon according to FBA shipping policies (e.g., putting the correct weight or
This way, Amazon can give you
accurate FBA fee estimates.
Inaccuracies in your product’s weight or classification can cause Amazon to overcharge you in pick and
fees. Worse, they may reject
your shipment and charge you extra for non-compliance with their product preparation requirements.
Dimensional weight (AKA DIM weight) refers to the amount of space a unit, carton, or pallet occupies in
relation to its actual weight. It
can be calculated by multiplying the length, width, and height of your package, and then dividing the
product by a DIM factor (the
numerical digit by which you multiply the cargo dimensions to find the DIM weight– FedEx and Amazon uses
as the DIM factor, for
example). Major carriers and Amazon alike will charge you based on whichever is greater between DIM
and actual weight.
Unfortunately, being charged based on DIM weight could potentially result in higher shipping and
costs for some sellers.
Your product may be small and lightweight, but the bulky packaging (due to excessive amounts of foam
and bubble wraps, for
example) might push it into large or oversize categories with Amazon and major carriers, resulting in
having to pay a few dollars
more. Basically, you would want to keep your packaging small to avoid the oversize category.
Some sellers within our online community have already seen their FBA fees increase by $1 per unit, which
be quite considerable,
especially for those with thin profit margins.
Use an FBA calculator when you are researching a new Amazon product to add to your catalog. This
will help you calculate the
estimated FBA fees associated with selling that product on Amazon and can help to determine the profit

4 Tips to Increase FBA Profit Margins
Amazon’s FBA program is one of the most popular fulfillment methods for new and seasoned sellers.
Amazon FBA fees also change frequently, so having a good inventory management strategy is key to staying
top of things.
Below are some tips for improving inventory performance to maximize profits while keeping FBA fees low.
Streamline Your Inventory Process
Two inventory pains that cost sellers a lot are stocking out and overstocking.
For example, carrying excess inventory comes with holding costs that can hurt your business. Holding
typically include warehouse
expenses, additional storage fees, opportunity costs, insurance, and spoilage/shrinkage losses. These
get higher the longer you let
your excess inventory sit in a warehouse unsold.
Stocking out is another problem that can eat into your budget. There are apparent stockout costs like
rankings, lost income, and
express air shipping, but there are also hidden costs that often lurk below the surface. Some of these
include unhappy customers,
productivity loss, and costs you may incur when you accept backorders.
On Amazon, you can list a back-ordered product. Back-ordering is ideal for top sellers that often run
stock due to high customer
demand. This process allows you to continue to sell without stock and then fulfill orders at a later
when the product becomes
However, since backorders take some time to arrive, potential customers may be put off by the long
ship date and decide to find
another seller, tanking your conversion rate and potentially your ranking along with it.
Another cost of backorder is paying extra for expediting the production and shipping of your items to
get them to Amazon faster.
And if you fail to ship a back-orderd item within your promised date, your On-Time Delivery Rate will
hit, Amazon will
automatically cancel the order, and worst of all, your seller account health will be affected due to
negative feedback that may be
generated from this.
These inventory pains typically stem from a lack of means to monitor inventory and forecast demand.
where using a sound inventory
management system like SoStocked comes in handy.
SoStocked streamlines your min/max restocking process, purchase order management, and supplier lead
times. Automating these
processes not only increases efficiency but also reduces stockouts and excess inventory.
Pro tip: Conduct a demand forecast to determine your projected sales over the next few
You might be tempted to pour all
your shipments into FBA right away, but don’t rush it. Send in a small volume of that inventory at a
time to prevent getting stuck
with slow-moving products or stocking out due to restock limit restrictions.
Conduct a Regular Amazon Inventory Cleanup
Regularly check your Inventory Health report by going to
Health. With this you can
monitor and track SKUs that could incur holding costs if you don’t remove or sell them quickly.
Review the columns in the report to see the current age of your sellable inventory, long-term storage
estimates, units shipped in the
last 30 days, and so on.
List all your aged inventory and prioritize those with the highest storage fees. Be strategic about how

next inventory clean-up date. Remember, Amazon conducts an inventory assessment every 15th of the month

you should get rid of your aged
inventory before the next clean-up date to minimize costs.
Consider bundling your slow sellers with top sellers or taking part in Lightning Deals to encourage
increased sales. Use ads to drive more
traffic to these products, especially those with poor sales rankings. Listing optimization to improve
conversion can also provide a
valuable sales lift. These techniques will help you manage your aged inventory better and improve your

sellers that need more
aggressive advertising efforts to increase sales and label it as “Advertising.” This way, you can
profit off of your slow
sellers instead of abandoning them.
Sync Up Your Marketing and Inventory Teams
Have you ever driven yourself into a stockout because of your aggressive PPC efforts? Or had to cancel a
Lightning Deal because you were
low on stock? This happens because sellers plan promotions or run PPC campaigns too aggressively without
coordinating their marketing
plans with their inventory plans.
If you had an overly aggressive PPC campaign a month ago, or worse, paid a digital ad agency, and their
stocked you out, then that's
even more lost profit because you paid to run yourself into a stockout.
You suddenly realize
how much money is wasted on stockouts because the marketing and inventory aren't working as one
machine. This is one of
the major reasons sellers end up in an out-of-stock situation. And that's one of the reasons why we
to talk about
Inventory-Minded Marketing or marketing with inventory in mind.
Inventory-Minded Marketing involves syncing up your inventory, marketing, and even your accounting team
throughout a marketing campaign to
ensure all teams are working together to assist each other in making as much profit as possible by
stockouts and overstocking.
For instance, your marketing team plans out their Prime Day marketing strategies to maximize the number
sales they expect to make over
that period. Your head of marketing should communicate this to the inventory manager so that her team
then build a sound forecast
around that plan. The inventory team makes sure this plan does not create any inventory stockouts, and
provides vital data so that
marketing can understand when they can push and when to hit the brakes.
The accounting team then uses this composite inventory-minded marketing plan and takes care of
securing any needed funding, and
paying suppliers promptly to avoid delays in manufacturing and releasing your inventory.

Timeline to visualize
your inventory plans over time. This helps to keep both teams informed of your current stock levels

Use a Reimbursement Service to Save on Amazon Fees
Claim the money Amazon owes you with the help of reimbursement service providers. Just because Amazon
rejects your reimbursement request
doesn't mean it's a closed case.
I recommend working with a service provider that understands the process in detail, like
Getida. They specialize in
recovering your money and can
usually find a lot more money than your typical Amazon software suite that happens to have automated
reimbursement management as just one
of their many features.
Getida knows how to get requests approved that have been rejected in the past. If you’ve had issues with
getting approved, you need a
service that understands the ins and outs of Amazon’s reimbursement program.
The sooner you try to get back the money you’re owed, the better, as you only have 18 months to file
reimbursement claims. Requests
submitted after the deadline are not eligible for reimbursement.
Whether you're a newbie or a seasoned seller, gaining a deeper understanding of Amazon FBA fees can help
protect your profit margins
and inform your pricing decisions.
Use the FBA calculator to determine your product’s profit potential before pulling the trigger. Running
profit calculations will also
help you decide whether or not it’s a good idea to sell it through FBA – or at all.
Finally, streamline your inventory processes to avoid the costly consequences of stocking out and
overstocking to increase your profit
margin. And if you currently have a large volume of excess units, consider selling them at a discounted
price to increase sales, boost
rankings, and ultimately improve your overall inventory health.
