Amazon FBA Fees vs a 3PL: Which Costs Less in 2026?

Fulfillment, storage and aged-stock fees, set against a 3PL quote

Brands planning an Amazon launch often ask us two versions of the same question:

"We only sell on Amazon. Do we still need a 3PL?"

"Amazon keeps raising fees. Wouldn't our own warehouse cost less?"

The short answer: for a few fast-selling items sold only on Amazon, FBA usually costs less. For slow stock, multichannel orders and Q4 storage, a 3PL usually costs less.

The catch is that the two price lists measure different things. Amazon's fulfillment fee includes delivery to the customer; a warehouse's pick-and-pack rate usually does not. And since October 15, 2026, Amazon's holiday peak fees and Q4 storage rates are in effect.

For the basics (what a 3PL does, and how FBA, Multi-Channel Fulfillment and AWD differ), start with What Is a 3PL, and When Does Your Brand Need One?. This post goes deeper on the fees, line by line.

1. Amazon FBA fees in 2026: what the fulfillment fee covers

Amazon's fulfillment fee is charged per unit, and it covers delivery. Amazon's FBA page says fulfillment costs include "picking, packing, and shipping orders, as well as handling customer service and returns," based on the product's price, weight and dimensions.

For a large standard item of 4 to 8 oz priced $10 to $50, Amazon's 2026 fee table gives:

January 15 to October 14, 2026: $3.95. With the 3.5% fuel and logistics surcharge that started April 17, 2026: about $4.09.
October 15, 2026 to January 14, 2027 (peak): $4.21. With the surcharge: about $4.36.

So $3.95 and $4.21 are before the surcharge; $4.09 and $4.36 include it. Amazon's page gives no end date for the surcharge. Per Amazon's announcement as reported by Chain Store Age, the peak increase averages $0.32 per unit, the same as in 2025.

The January 2026 changes were uneven. On the same Amazon page, standard-size items priced $10 to $50 rose $0.08 per unit on average, but small standard rose $0.25 and large standard $0.05. Check your own row, not the average.

Any Amazon order that ships today pays the peak rate. To compare Amazon with your own fulfillment on a real product, use Amazon's Revenue Calculator, its FBA fee calculator. For referral fees and ads on top, see what's left of $24.99 on each channel.

2. What a 3PL charges to pick and pack, and what it leaves out

Warehouses bill pick and pack and postage separately. The Fulfillment Advisor's 2026 survey (August 2026, about 500 providers, about 80% in the US) reports these averages:

One-item D2C order: $3.21 ($2.73 base order charge plus $0.48 for the item)
B2B order: $4.86 plus $0.98 per item
Shipping carton: charged separately by 57% of providers, $1.46 on average

These are industry averages, not quotes, and none include postage.

That gives you a break-even line. If the warehouse includes the carton, subtract $3.21 from Amazon's $4.09: $0.88 is left for postage. If your carrier rate per parcel is above $0.88, Amazon costs less per order. During peak, the line moves to $1.15 ($4.36 minus $3.21). If the carton costs $1.46 extra, you are at $4.67 before postage, already above Amazon.

3. Amazon storage fees vs 3PL storage: the Q4 jump

Storage is where a 3PL usually wins. Under Amazon's monthly storage fees, standard-size items cost $0.78 per cubic foot a month from January to September and $2.40 from October to December, about 3.1 times as much. Oversize goes from $0.56 to $1.40.

The same survey puts warehouse storage at $0.45 per cubic foot a month on average, or $19.37 per pallet (reported range about $6 to $40). Pallet and cubic-foot rates use different bases, so do not compare them directly. A cubic foot is length times width times height in inches, divided by 1,728.

At $0.45, the survey average is about 42% below Amazon's January-to-September rate and about 81% below its Q4 rate. For example, with 25 cubic feet of stock:

Amazon: $19.50 in September (25 × $0.78), $60 in October (25 × $2.40)
Survey average: $11.25 (25 × $0.45)

In this example, stock that will not sell by December costs $48.75 more a month at Amazon. For holiday inbound and carrier dates, see our BFCM 2026 checklist.

4. The surcharges for holding too much stock

Two surcharges sit on top of base storage when stock outruns sales.

The storage utilization surcharge applies only if you meet every condition on the storage fee page: a Professional account, a first US shipment more than 365 days ago, average daily volume of at least 25 cubic feet in the size tier, and a storage utilization ratio above 22 weeks. It then applies to stock aged over 30 days, from $0.44 per cubic foot (22 to 28 weeks) to $1.88 (52 weeks and over) for standard size.

The aged inventory surcharge changed on January 16, 2026. Per cubic foot, it is $0.50 at 181 to 210 days and $5.45 at 271 to 300 days. From 366 to 455 days it is $6.90 or $0.30 per unit, whichever is higher, and from 456 days $7.90 or $0.35 per unit. Amazon takes a snapshot on the 15th of each month.

Past about nine months, the aged inventory surcharge costs more than Q4 base storage.

5. The fee for holding too little

Run too lean and Amazon charges for that too. The low-inventory-level fee applies when both your 30-day and 90-day historical days of supply fall below 28. For large standard items up to 3 lb, it is $0.97 per unit at 0 to 13 days, $0.70 at 14 to 20 days and $0.36 at 21 to 27 days.

New brands get some room in year one:

New Professional sellers are exempt from the low-inventory-level fee for their first 365 days.
The storage utilization surcharge starts only after a year of US shipments.
Capacity limits do not apply to new Professional sellers active for under 39 weeks. After that, each storage type gets a monthly limit, and Amazon blocks new shipments above it.

Keep stock at Amazon between about 4 and 22 weeks of sales. The rest needs somewhere else to live.

6. The hybrid: a 3PL holds the stock, Amazon gets weeks of supply

You can also use both: keep bulk stock at an outside warehouse and send Amazon a few weeks of supply at a time. That adds three costs:

Warehouse receiving: $2.25 per carton or $8.75 per pallet (survey averages)
Prep for Amazon at the warehouse: $2.00 to $3.00 per order and $0.40 per label (survey averages)
Inbound placement fee: $0.20 to $0.40 per unit for a large standard item of 12 oz or less sent to one location (minimal split). With an Amazon-optimized split and at least five identical cartons or pallets, it is zero.

The $0.50 per unit inbound example in our channel margin post includes freight on top of these rates.

Amazon Warehousing and Distribution (AWD) is the other place to hold bulk stock. Per Amazon's AWD page, storage is $0.57 per cubic foot a month on the West Coast and $0.48 in the East, Southeast and South Central regions, and processing is $1.40 per box in and out. There is no holiday surcharge, and inbound placement is included. Products auto-replenished from AWD (70% or more) are exempt from the low-inventory-level fee and the storage utilization surcharge.

AWD earns its place through auto-replenishment and fee waivers, not cheap storage. At $0.48 to $0.57, it is not below the $0.45 survey average.

7. Selling beyond Amazon: MCF, FBM and Seller Fulfilled Prime

Amazon stock can ship Shopify and TikTok Shop orders through Multi-Channel Fulfillment (MCF), but MCF fees rose $0.30 per unit on average in 2026, and the 3.5% surcharge applies.

Retail pallets, returns and repackaging are warehouse work. In the 2026 survey, 87% of providers charge for returns, $3.56 on average. Warehouses also have fixed costs: the monthly minimum averages $752.08, from $150 to over $1,500.

If you ship orders yourself (FBM fulfillment) and still want the Prime badge, the route is Seller Fulfilled Prime: a Professional account ($39.99 a month plus selling fees), prequalification on performance, and a 30-day trial.

With two or more channels, the question is no longer which warehouse, but where the stock sits and how it is split.

Amazon FBA fees vs a 3PL, line by line

Amazon figures come from the 2026 fee table and storage fees. 3PL figures are averages from The Fulfillment Advisor's 2026 survey.

Cost line	Amazon FBA	US 3PL (survey average)
One-item order, 4 to 8 oz large standard	About $4.09; about $4.36 in peak (surcharge and delivery included)	$3.21 pick and pack; postage extra
Shipping carton	Included in the fee	Extra at 57% of providers, $1.46 average
Storage per cubic foot a month	$0.78 (Jan to Sep), $2.40 (Oct to Dec)	$0.45
Slow stock	Aged inventory surcharge from 181 days; utilization surcharge above 22 weeks if eligible	Not in the survey; check your contract
Receiving or inbound	Placement fee $0.20 to $0.40 per unit, or $0 with 5+ identical cartons	$2.25 per carton, $8.75 per pallet
Orders it can ship	Amazon orders (others through MCF)	Any channel, including retail pallets
Usually cheaper for	A few fast sellers, Amazon only	Slow stock, several channels, Q4 storage

When Amazon costs less, and when a 3PL does

Amazon usually costs less when you sell only there, carry a few SKUs that sell fast, ship light standard-size items, and need the Prime badge to convert. A 3PL usually costs less when stock sits long, the same stock serves several channels, items are bulky or fragile, returns are frequent, or Q4 storage is a large share of your cost.

Before you decide, answer these:

1. Is your carrier rate per parcel below $0.88 ($1.15 during peak)?

2. How many weeks of sales are you sending to Amazon?

3. Will you add a channel outside Amazon in the next year?

Wrap-up

Putting Amazon FBA fees next to a pick-and-pack rate is only half the comparison. Amazon's fee includes delivery, and a 3PL's real edge is storage and multichannel shipping. Peak fulfillment fees run until January 14, 2027, and Q4 storage is $2.40 per cubic foot through December.

LinkONE runs a 3PL warehouse in Fullerton, California, with Amazon FBA prep and FBM fulfillment, retail shipping for Costco and Walmart, order sync with Shopify, Amazon, TikTok and Walmart, and returns processing.

In the end, FBA vs a 3PL is rarely either-or. It is how much stock you keep at Amazon and how much you keep elsewhere.
