Amazon FBA Fees 2026: Every Fee, Rate and Example

Amazon FBA fees are what you pay Amazon to store, pick, pack, ship and return your products, on top of the referral fee every seller pays.

This guide lists every US FBA fee with the rates in force as of October 2026, a worked per-unit example, and how the total feeds the ACOS your ads can afford. We update it each January, when Amazon's new rate card takes effect.

What Are Amazon FBA Fees?

Amazon FBA fees are the charges for using Fulfillment by Amazon, the service where Amazon stores your inventory and fulfills each order.

They are separate from selling fees. The referral fee (usually 8% to 15% of the sale price) and the $39.99 Professional plan apply whether you use FBA or ship orders yourself.

The easiest way to keep them straight is by when they are charged. Some hit every unit sold, some every unit you send in, some every month, and some only when something goes wrong.

What Changed in 2026

Amazon announced its 2026 US fee update on October 15, 2025. FBA fees rose by an average of $0.08 per unit sold, after no increase in 2025, and Amazon added no new FBA fee types.

The average hides big differences by price and size. The fee change summary in Seller Central lists what moved on January 15, 2026:

• Standard-size, priced $10 to $50: small standard up $0.25 per unit on average, large standard up $0.05.

• Standard-size, priced over $50: small standard up $0.51, large standard up $0.31. Amazon now charges a third, higher price band for these products.

• Standard-size, priced under $10: small standard up $0.12, large standard unchanged. These keep a discount of $0.86 per unit on average.

• Bulky items: the old Large Bulky tier split into Small Bulky and Large Bulky. Small Bulky fees fell about $2.06 per unit and Extra-Large fees about $2.08.

• Low-inventory-level fee: now measured per FNSKU instead of per parent ASIN, now charged on bulky items, and grocery is exempt.

• Aged inventory: a new top tier for units older than 15 months, and a higher minimum for units 12 to 15 months old.

Two changes came later in the year. A 3.5% fuel and logistics surcharge has applied to US FBA fulfillment fees since April 17, 2026, as Amazon's 2026 fulfillment fee page states.

Then holiday peak fees started on October 15, 2026. The surcharge applies on top of them, and Amazon has not given an end date for it.

Amazon FBA Fulfillment Fees by Size Tier (as of October 2026)

The fulfillment fee is the largest FBA cost on most products. It is charged per unit when the order ships and depends on three things: size tier, shipping weight and the item's price.

1. Find the Size Tier

Amazon measures the product in its packaging. These are the 2026 size tiers:

2. Work Out the Shipping Weight

Shipping weight is the greater of unit weight and dimensional weight for every tier except small standard and Extra-Large 150+ lb, which use unit weight only.

Dimensional weight is length x width x height in inches, divided by 139. A light, boxy product often pays for air.

3. Read the Rate for Its Price Band

Since January 15, 2026, standard-size items have three price bands: under $10, $10 to $50, and over $50. An item priced exactly $10 or $50 pays the $10 to $50 rate.

These are the non-peak rates from January 15 to October 14, 2026, excluding apparel and dangerous goods, before the 3.5% surcharge:

Apparel and dangerous goods have their own rate cards on the same Amazon page, both slightly higher. Products under $10 get Low-Price FBA rates automatically, which is the under $10 column above.

The price bands create a real pricing decision. Moving a $10.49 product to $9.99 cuts its fulfillment fee by $0.82 on a large standard 12 to 16 oz item, before you even count the lower referral fee in some categories.

2026 Holiday Peak Fees: October 15, 2026 to January 14, 2027

Peak fulfillment fees apply to every unit that ships from October 15, 2026 to January 14, 2027. The date that counts is the ship date, so an order placed on October 14 that ships on October 15 pays peak rates.

Amazon says the peak increase averages the same as last year, $0.32 per unit, according to Supply Chain Dive's report of the July 2026 announcement. The 3.5% surcharge applies on top.

Peak season also raises storage. Standard-size storage goes from $0.78 to $2.40 per cubic foot from October to December, so inventory that arrives too early pays twice.

Our Q4 preparation guide covers how peak fees change deal-day bids.

Monthly Storage and Aged Inventory Fees

Monthly Inventory Storage Fee

Amazon charges monthly storage on the daily average volume your units take up, in cubic feet. It is billed between the 7th and 15th of the following month.

A storage utilization surcharge comes on top for Professional sellers past their first 365 days, with at least 25 cubic feet stored, whose storage utilization ratio is above 22 weeks. The ratio is your average stored volume divided by your average weekly shipped volume over the last 13 weeks.

The surcharge only applies to units older than 30 days. For standard-size it runs from $0.44 per cubic foot (22 to 28 weeks) to $1.88 (52+ weeks), so a slow account can pay $4.28 per cubic foot in December.

Aged Inventory Surcharge

The aged inventory surcharge is assessed on the 15th of each month for units older than 181 days, in addition to monthly storage.

The jump at day 271 is the one to plan around. The surcharge goes from $1.50 to $5.45 per cubic foot overnight, and from there removing a slow unit is usually cheaper than keeping it.

Our inventory management guide and IPI score guide cover how to stay out of these tiers.

Low-Inventory-Level Fee

The low-inventory-level fee is added to the fulfillment fee of every shipped unit when stock runs too thin. It applies only when both your 90-day and 30-day historical days of supply are below 28 days.

Since January 2026 it is calculated per FNSKU, so one fast variation running low triggers the fee on that variation only. Grocery is exempt, and slow movers stay exempt.

Here is where storage and stock pull against each other. Hold too little and you pay this fee on every sale; hold too much and you pay storage and aged surcharges. Four to eight weeks of cover is the range we aim for outside Q4.

Inbound Placement Service Fee

The inbound placement service fee pays Amazon to spread your inventory across its network. The fewer locations you ship to, the more you pay per unit.

Large standard now has eight weight bands, from $0.20 to $0.40 under 12 oz up to $0.55 to $1.90 at 15 to 20 lb.

The free option is not free. You pay the carrier to send boxes to five or more warehouses, so compare the placement fee against your extra freight before you choose.

Shipments that never arrive, arrive late or go to the wrong place now pay a single inbound defect fee of about $0.60 per unit on average instead of both fees.

Returns, Removal and Disposal Fees

Returns Processing Fee

Apparel and shoes pay a returns processing fee on every returned unit, from $1.65 for small standard. Everything else pays only on returns above a category threshold, from $1.78 per unit for small standard and $2.36 for a light large standard item.

Thresholds differ a lot: 2.9% for grocery, 4.7% for toys, 8.1% for home and kitchen, 12.8% for luggage. A product returned above its threshold pays the fee on the excess units only.

Refund Administration Fee

When you refund an order, Amazon returns the referral fee minus a refund administration fee of $5.00 or 20% of the referral fee, whichever is less.

Removal and Disposal Fees

Removal and disposal orders cost the same per unit. Only the lightest band changed in 2026.

Liquidation is the alternative: a 15% referral fee on the recovery value plus a processing fee from $0.25 per unit.

Selling Fees That Sit Beside FBA

These are not FBA fees, but they belong in the same per-unit math. All figures are from Amazon's selling fees page as of October 2026.

• Selling plan: Professional is $39.99 a month; Individual is $0.99 per item sold.

• Referral fee: 15% in most categories, 8% in consumer electronics and computers, 45% for Amazon device accessories, with a $0.30 minimum in most categories. Apparel is tiered at 5%, 10% and 17% by price.

• Closing fee: $1.80 per media item (books, DVDs, music, software, video).

If you are weighing whether FBA is worth it at all, our FBA vs FBM comparison runs the same numbers for self-fulfillment.

Worked Example: Amazon FBA Fees on One $25 Product

Here is the full per-unit cost for one example product: a $25 kitchen item, 14 oz packaged, in a 10 x 6 x 4 inch box. That makes it large standard, 12+ to 16 oz, in the $10 to $50 band.

The product cost, returns allowance and storage time are illustrative; the fee rates are Amazon's. If the item also dipped below 21 days of supply in November, the $0.36 low-inventory-level fee would cut profit to $7.41.

Amazon's Revenue Calculator returns the fee lines for any ASIN. Our FBA calculator walkthrough shows which inputs it misses, mainly storage time, returns and placement.

How FBA Fees Feed Break-Even ACOS

Every dollar of FBA fees is a dollar your ads cannot spend. That is why we treat the fee table as an advertising input, not just an operations one.

Break-even ACOS is profit before ad spend divided by price. At that ACOS, an ad-driven sale makes zero profit.

1. Total the Fees per ASIN

Use the fee lines from the worked example above, per ASIN, not an account average. A small standard $8 item and a $60 bulky item have nothing in common.

2. Calculate Break-Even ACOS

For the example, $8.52 ÷ $25.00 gives a 34.1% break-even ACOS outside peak. In November it drops to $7.77 ÷ $25.00, or 31.1%, before any deal discount.

3. Set Target ACOS Below It

Decide the profit you want to keep per ad sale. Keeping $3.00 means a target ACOS of ($8.52 − $3.00) ÷ $25.00, or 22.1%.

Our ACOS guide explains how to set targets by goal, and the break-even ACOS guide has the formula in full.

4. Re-Run It When Fees Change

Fees change on fixed dates: January 15 for the annual rate card, October 15 for peak, and January 15 again when peak ends. Bids set to the old break-even keep spending at the old margin.

A three-point drop in break-even looks small. On an ASIN spending $10,000 a month on ads at its old break-even, it is roughly $880 of monthly ad spend that no longer pays for itself.

Judge the whole picture with TACOS too, since organic sales carry the same fees but no ad cost.

How to Lower Your Amazon FBA Fees

1. Check Your Dimensions and Weight

Amazon's measurement sets your size tier. If it is wrong, the FBA Re-measurement and Reimbursement Tool in Seller Central can correct it and refund the overcharge.

2. Shrink the Package

Small standard ends at 0.75 inches thick. A packaging change that drops a product from large to small standard, or from Small Bulky to large standard, saves more than any bid change. See our packaging requirements guide.

3. Price Around the Bands

The $10 and $50 thresholds now move fulfillment fees. Test whether a price just below a threshold earns more after fees and conversion.

4. Keep Four to Eight Weeks of Stock

Below 28 days of supply you pay the low-inventory-level fee on every sale. Far above it you pay storage, the utilization surcharge and, eventually, aged inventory fees.

5. Remove Before Day 271

Run the aged inventory report monthly. A promotion, a deal or a removal order before the 271-day step is cheaper than holding.

6. Compare Inbound Options Properly

Price the placement fee against the extra freight of Amazon-optimized splits. For heavy large standard items, the minimal-split fee can pass $1.50 per unit.

Mistakes We See in Real Accounts

• Using one ACOS target for every ASIN. FBA fulfillment fees range from $2.43 to over $190 per unit, so break-even ACOS does too.

• Forgetting the surcharge. The 3.5% is easy to miss in a rate card that excludes it, and it lands on every unit.

• Running Q4 bids on September margins. Peak fulfillment and storage fees lower break-even on every FBA unit from October 15.

• Sending holiday stock in September. It pays peak storage from October to December and risks aged fees if it doesn't sell.

• Letting a hero variation run thin. Since the change to FNSKU-level measurement, one low variation pays the low-inventory fee on its own.

• Comparing FBA with FBM on fulfillment fees alone. FBA listings usually convert better with Prime, which changes the ad math too.

How We Track FBA Fees and Ad Spend in Adbrew

Adbrew is an agentic retail media management platform for Amazon and Walmart. Fees matter to it because they decide what every ad dollar can earn.

Profitability in Adbrew puts Amazon fees, ad spend, cost of goods and net profit in one statement, week by week. When peak fees start on October 15, the Amazon Fees line moves and you see the effect on net profit in the same view.

From there, the target ACOS you set per product drives the rules you set for bids and budgets in Sponsored Ads management. Retail-aware automation pauses ads when an ASIN runs out of stock, so you don't pay for clicks to an empty listing.

Adbrew Intelligence can also answer the question directly: "which ASINs are spending above break-even ACOS since peak fees started?" builds the list from your own data.

Keep the Fee Table and the Bids in Step

FBA fees change on dates you can put in a calendar. The sellers who protect their margin are the ones whose ACOS targets move on the same dates.
