If you’re selling on Amazon via the FBA program, you’ll need to understand FBA fees inside and out.

The referral fees, the pick and pack fees, the order handling fees, the storage fees, the refund administration fees… there’s a lot of different types.

And it can get confusing.

Luckily, there’s calculators and automation to help you out.

So today, we’re going to dive into exactly what the types of Amazon fees are, when they’re charged, how much they cost, and most importantly, how you can leverage some tips and tricks to squeeze the most profit out of every sale.

Then, we’ll dive into how you can automate this process so you don’t have to worry about it.

So let’s get started!

Part 1: The Types of Amazon Fees

Amazon Fulfillment Fees

I like to call the fulfillment fees the most important type of fee. This is because these fees often are the largest percentage of your item’s fee amount.

Fulfillment fees are determined by the weight and dimensions of your item.

Items can be classified into four distinct categories: Small and Light (which we’ll cover down below in the Minimizing section), Standard, Oversize, and Special Oversize.

Small and Light

To be in the Small and Light category, your item needs to match a special criteria as well: it has to be under $7.

Small and Light items need to be stickered, less than 16x9x4 inches, and weigh 10 ounces or less.

In addition to price, weight and dimension restrictions, there’s also a few categorical restrictions on Small and Light items:

Restricted products, adult products, Hazmat, temperature sensitive goods, slower moving products are not eligible for Small and Light.

You can learn more about Small and Light criteria here.

Ultimately, Small and Light is the category you want to be in if you have a fast-moving, low-price SKU. The prep may be a little bit extra, but the savings in fees more than makes up for it.

Standard Size

Standard Size is probably the most common category of FBA SKUs. A standard size item must be:

  • 20 pounds or less
  • Less than or equal to 18″ on its longest side
  • Less than or equal to 14″ on its median side
  • Less than or equal to 8″ on its shortest side

Standard Size also has a Small Standard Size tier, which requires the item to be no heavier than 12 ounces, and no bigger than 15x12x.75 inches.

Size TierSmall Standard Size <10 oz.Small Standard Size (10-16 oz)Large Standard Size (<10 oz)Large Standard Size (10-16 oz)Large Standard Size (1-2 lb)Large Standard Size (2-3 lb)Large Standard Size (3-21 lb)
Fulfillment Fee (Apparel)$2.92$3.11$3.70$3.81$5.35$5.95$5.95 + $0.38/lb above the first 3 lb
Fulfillment Fee (non-Apparel)$2.50$2.63$3.31$3.48$4.90$5.42$5.42 + $0.38/lb above the first 3 lb


The Oversize category has four tiers of sizes: Small Oversize, Medium Oversize and Large Oversize.

Small Oversize

A Small Oversize item is larger than a Standard Size item, but must be:

  • Less than or equal to 70 pounds
  • Less than or equal to 60 inches on its longest side
  • Less than or equal to 30 inches on its median side
  • A combined length + girth (or (shortest + median side) * 2) of 130 inches or less
Medium Oversize

A Medium Oversize item must be:

  • Less than or equal to 150 pounds
  • Less than or equal to 108 inches on its longest side
  • A combined length + girth (or (shortest + median side) * 2) of 130 inches or less
Large Oversize

A Large Oversize item must be:

  • Less than or equal to 150 pounds
  • Less than or equal to 108 inches on its longest side
  • A combined length + girth (or (shortest + median side) * 2) of 165 inches or less
Special Oversize

A Special Oversize item is any item not fitting the criteria of any of the other Oversize categories above, which means it has over:

  • Heavier than 150 pounds
  • More than 108 inches on its longest side
  • A combined length + girth (or (shortest + median side) * 2) of more than 165 inches
Size TierSmall Oversize (<71 lb)Medium Oversize (71-151 lb)Large Oversize (<151 lb)Special Oversize
Fulfillment Fee$8.26 + $0.38/lb above the first 2 pounds$11.37 + $0.39/lb above the first 2 pounds$75.78 + $0.79/lb above the first 90 pounds$137.32 + $0.91/lb above the first 90 pounds

Amazon Referral Fees (or Variable Closing Fees)

Amazon Referral Fees, also referred to as the Amazon Variable Closing Fees, are percentage-based fees that are charged upon every sale.

These fees are based on the sales price of that particular ASIN at the exact time of purchase.

These percentages vary by the primary category of your ASIN, as noted below:

Monthly Subscription Fee

For Pro Sellers, the monthly subscription fee is $39.99 per month.

Amazon Storage Fees

Storage Fees are costly for a lot of sellers, yet many sellers completely forget about them.

Staying on top of inventory storage fees is incredibly important.

There’s two types of storage fees: Monthly Storage Fees and Long-Term Storage Fees.

Monthly Storage Fees

Monthly storage fees are entirely based on how much total volume you have in the FBA warehouses, averaged over the month.

They vary by total volume, as well as the size type of your SKUs, and whether or not your SKUs are hazmat.

Additionally, monthly storage fees are assessed with two different tables: one for Q1-Q3 (January-September), and one for Q4 (October-December).

Here are the fees for non-hazmat goods:

MonthStandard SizeOversize
January - September$0.75/cu. ft.$0.48/cu. ft.
October - December$2.40/cu. ft.$1.20/cu. ft.

And for hazmat goods:

MonthStandard SizeOversize
January - September$0.99/cu. ft.$0.78/cu. ft.
October - December$3.63/cu. ft.$2.43/cu. ft.

Long-Term Storage Fees

Long-term storage fees are assessed on any items that are stuck in FCs for more than 365 days – i.e. stale inventory.

We recommend always never over-sending in inventory, as fulfillment centers are not storage facilities – they’re meant just to handle enough inventory for the near future.

For longer-term SKU storage, consider an FBA prep facility or your own warehouse.

Long-term storage fees are assessed on the 15th day of each month, and are assessed at $6.90 a cubic foot, with a minimum per-unit charge of $0.15 each.

These can add up quickly on lower-volume SKUs, so we definitely recommend cleaning up your catalog each month to make sure you aren’t assessed any LTSFs.

Removal fees are often much cheaper, or worst case, destroying your inventory as necessary to prevent incurring large LTSFs.

Amazon Removal Order Fees

If you ever want to remove a stale or low-performing SKU from Amazon’s fulfillment centers, or, of course, you want to avoid Long Term Storage Fees, we recommend placing a removal order.

Removal order fees are assessed based on the size and weight of your item.

For standard size items, the removal order fees are the following:

Shipping WeightRemoval or Disposal Fee Per Unit
0 to 0.5 lb$0.25
0.5 - 1 lb$0.30
1 - 2 lb$0.35
> 2 lb$0.40 + $0.20/lb above the first 2 lb

For oversize items, or items requiring special handling, the removal order fees are the following:

Shipping WeightRemoval / Disposal Fee Per Unit
0 to 1 lb$0.60
1 - 2 lb$0.70
2 - 4 lb$0.90
4 - 10 lb$1.45
> 10 lb$1.90 + $0.20/lb over the first 10 lb

Amazon Returns Processing Fees

Returns processing fees occur on categories where Amazon offers free return shipping. You can read more about these fees on Amazon’s site here.

These fees occur in the following categories:

  • Apparel
  • Watches
  • Jewelry
  • Shoes, Handbags and Accessories
  • Luggage

This fee is equal to the total fulfillment fee for the given SKU.

It’s assessed on a single unit, so if multiple units are returned, you may be charged more than the combined fulfillment fee (because it’s a single unit’s fulfillment fee multiplied, rather than a fulfillment fee and an additional smaller fee per each additional).

Amazon Unplanned Service Fees

Unplanned Service Fees occur when you forget to do some form of prep – i.e. polybagging or stickering – and Amazon assigns a fulfillment center worker to complete the task instead.

These fees vary based on which service is performed, and how many units it’s done on.

Part 2: How to Minimize Amazon Fees

Now that you know about all of the types of fees, you’re likely thinking, “Wow, that’s a lot of fees! How the heck am I supposed to squeeze the most out of every sale?

I feel you. Let’s get moving on how we can get those fees down, while playing by the rules.

Use Small and Light Whenever Possible

My #1 trick to lowering your overall FBA fees on smaller, cheaper items is to leverage the Small and Light program to its full extent.

A lot of sellers still don’t leverage Small and Light, either because of the increased prep requirements or simply not knowing about it.

But leveraging this program gives you a huge competitive advantage on these SKUs.

This program can lower your fees on some items by upwards of $1, making items that were previously unprofitable sudden winners.

For the Small and Light program, your item must be less than or equal to 16x14x9 inches, 10 ounces or less, and priced less than $7. Additionally, it must be relatively fast moving (~24 units or so a month).

In the USA, Small and Light fees are assessed based on the weight of your item:

WeightFulfillment Fee Per Unit
Less than or equal to 4 ounces$1.97
4+ ounces to 10 ounces$2.39

As you can see, even taking into account the other fees associated (the fees above are purely fulfillment fees), Small and Light can give a huge boost in overall profits.

Avoid Larger, Bulkier Items

Avoiding larger, bulkier items not only saves you when it comes time to recall if necessary, but it also lowers your inbound shipping costs, outbound shipping costs, and fulfillment fees.

Oversize and special oversize items can get pricey – especially once you factor in storage fees.

We recommend sticking to smaller, faster moving items to increase your turnover and overall profits.

Avoid Low Turnover SKUs

This is also crucial, as lower turnover SKUs will result in higher storage fees, and ultimately, long-term storage fees if they don’t sell fast enough.

Sticking to items that turn over moderately well will help you avoid higher storage fees and increase your profits in the long run.

Avoid Items with a High Return Rate

The more returns an SKU has, the more potential for negative feedback, used item returns, and overall customer unsatisfaction.

We recommend using Sellonaut’s review rating filter to help with this.

If items have an average review rating of say, 4 stars or higher, we can venture to guess that customers aren’t confused or angered by the quality of the product.

Thus, you’ll be left with happier customers and ultimately, less returns!

Part 3: How to Calculate Amazon FBA Fees Using the Amazon FBA Fee Calculator

Now that we understand all of the fees that go into a sale, it’d be quite complex to do this by hand.

Especially if you’ve got thousands of ASINs.

Now, luckily there’s quite a bit of fee updating software such as Sellonaut to keep track of this.

But what if you have just a single ASIN?

That’s where the Amazon FBA Fee Calculator comes in. Simply enter an ASIN and hit calculate to get your results.

Additionally, you can enter “what if” scenarios based on the item’s buy box price, as well as enter your wholesale cost to determine your ROI.

Part 4: How to Keep Track of Amazon Fees

Now that we know all about these fees, we can agree that it’s crucial to keep track of them.

Unfortunately, many sellers don’t keep track of their fee amounts.

They may not have an interactive dashboard, or updating tool, to let them know when things change.

That’s a problem. Because if a competitor decides to do some blackhat tricks and ups your item dimensions overnight, you could face hundreds of sales with the wrong fee amount.

Luckily, there’s a few ways you can keep track of these fees.

Method 1: The Manual Check

Of course, you can always check manually on your detail pages, or by using the official Amazon FBA Fee Calculator.

using the amazon fba fee calculator

Using the Amazon FBA fee calculator to learn more about these air fresheners. It works okay for a one-off search, but doing it in bulk – and updating data as prices change – can take up quite a bit of time very fast.

That said, this method isn’t scalable – especially if you’re a large private label seller, or a larger reseller that has potentially tens of thousands of active SKUs.

This brings us to Method #2, or as I like to call it, “the smart way“.

Method 2: The Smart Way

Method #2 involves leveraging the power of software and automation to keep track of your fees.

Luckily, you can do this with Sellonaut!

So right now, let’s dive into Sellonaut and show you how to do that.

First, I’ll select the ASIN I want to track. These ASINs are already in my Sellonaut account because I’ve previously added them in as a list of UPCs. You can learn more on how to convert UPCs to ASINs in Sellonaut here.

Back at it again with the Wonder Woman Air Fresheners.

Now, I’ll take note of those fees. Right now, the fees are $5.18. That’s fulfillment and variable closing, plus one month of storage cost.

changing filters in sellonaut for automatic fee updates

You can’t see it here, but I’ve edited our fees as well in the “Other Filters” menu, to confirm our new export criteria.

Now, I’ll change my export criteria. I’ll force the ASIN to this one, and set filters if fees are greater than what they currently are.

Then I’ll create an export – let’s call this “Air Freshener Fee Changes.” And I’ll set the export frequency to daily.

Creating a recurring export in Sellonaut is easy.

Boom! Now I’ll get an email alert any time my fees change for that ASIN.

These filter criteria can be changed or modified across your entire catalog.

Plus, as soon as any of your fees change, they’ll show up differently in any Sellonaut export – because Sellonaut updates your data 24/7.

As you can see, Sellonaut is basically an automated FBA fee calculator – while refreshing the rest of your data, fees are refreshed as well. This allows you to keep track of your individual SKUs and your profit levels, and helps you maintain consistency across your purchase orders and catalog.
