For most standard-size products priced between $10 and $50, FBA costs less than merchant fulfillment (FBM) unless you can buy shipping labels for well under about $3 for very light items, or under about $5 to $7 for items between 1 and 3 pounds. That is the result of the worked model below, which uses the 2026 US fee tables and three hypothetical products. The deciding number is your real cost to pick, pack and ship one order yourself. If it is lower than the FBA fees you would avoid, FBM wins. If not, FBA wins, and slow sellers can still lose that advantage to storage fees.
This guide covers US sellers on Amazon.com. It shows which costs belong in each column, how to find your own break-even label cost, and where the comparison usually goes wrong. The fee figures were checked on October 18, 2026; the important caveat on where they come from is in the next section.
Hypothetical model by E-commerce Partners. If your all-in label cost for an order is below the bar, FBM is cheaper for that product. Assumptions are listed in the model section.
Where the fee numbers come from
Amazon publishes its full FBA rate tables inside Seller Central help pages, which could not be loaded by automated fetching for this article. What could be confirmed directly from Amazon on October 18, 2026:
- Amazon’s announcement of its 2026 US fees said FBA fees would rise by an average of $0.08 per unit sold, that there would be no new FBA fee types in 2026, and that changes took effect January 15, 2026 unless otherwise noted.
- Amazon’s pricing page lists the Professional plan at $39.99 a month or $0.99 per item on the Individual plan, and a 15% referral fee for categories including Home and Kitchen, Office Products, Sports and Outdoors, Toys and Games and Everything Else, with a $0.30 minimum for most categories. The referral fee is a percentage of the total price.
- Amazon’s FBA page says fulfillment fees depend on price, weight and dimensions, storage is charged monthly by cubic foot, inbound placement fees apply to standard and large bulky products, and aged inventory fees apply to items stored more than 181 days.
The per-unit fulfillment fees used below come from the 2026 US non-peak rate table as reproduced by three independent seller-services sites (GOAT Consulting, AMZ Prep and FBA Essentials), which matched each other for every row used here. The holiday peak fees come from AMZ Prep alone. Treat all of them as secondary figures and confirm your own in Seller Central’s Revenue Calculator or Fee Preview report before you decide.
What you pay under each method
The referral fee is the same whichever way you fulfill, so it does not decide the comparison. What changes is everything that happens after the sale.
Referral fee Yes, % of total price Yes, % of total price
Professional plan $39.99 a month $39.99 a month
Fulfillment fee per unit Yes, by size tier, weight and price band No
Shipping label to the customer Included in fulfillment fee You pay
Packaging and labour Mostly Amazon (you still prep and label) You pay
Freight into Amazon You pay No (but you pay to receive stock yourself)
Inbound placement fee Yes, for standard and large bulky items No
Monthly storage Yes, per cubic foot Your own space
Aged inventory, low inventory, returns processing fees Can apply No, but you handle returns yourself
Built from Amazon’s pricing and FBA pages and its fee announcements, checked October 18, 2026.The 2026 fulfillment fees that matter for a $10 to $50 product
FBA fees have three price bands: under $10, $10 to $50, and over $50. Most private-label products fall in the middle band, so that is the one shown here. Small standard covers items up to 16 oz that fit within 15 x 12 x 0.75 inches. Large standard covers items up to 20 lb within 18 x 14 x 8 inches.
Small standard 4+ to 6 oz $3.45 $3.65
Small standard 14+ to 16 oz $3.96 $4.18
Large standard 12+ to 16 oz $4.60 $4.89
Large standard 1+ to 1.25 lb $5.04 $5.34
Large standard 1.5+ to 1.75 lb $5.57 $5.89
Large standard 2+ to 2.25 lb $5.92 $6.29
Large standard 2.5+ to 2.75 lb $6.26 $6.66
Large standard 2.75+ to 3 lb $6.67 $7.08
US 2026 FBA fulfillment fees, $10 to $50 price band, non-apparel, as reproduced by GOAT Consulting, AMZ Prep and FBA Essentials (peak column: AMZ Prep). Checked October 18, 2026. Confirm in Seller Central.Two adjustments sit on top of these tables:
- The 3.5% fuel and logistics surcharge. Supply Chain Dive and Retail Dive reported that Amazon announced, in an April 2, 2026 Seller Central post, a 3.5% surcharge on FBA fulfillment fees in the US and Canada from April 17, 2026. Amazon described it as temporary but gave no end date. On a $5.57 fee it adds about $0.20.
- Dimensional weight. For large standard items, Amazon bills the greater of unit weight and dimensional weight, which is length x width x height in inches divided by 139. Small standard items are billed on unit weight.
Dimensional weight is where many sellers lose money without noticing. A 1.2 lb kitchen gadget in a 10 x 6 x 4 inch box has a dimensional weight of 240 / 139 = 1.73 lb, so it is billed in the 1.5+ to 1.75 lb row at $5.57, not the 1+ to 1.25 lb row at $5.04. Repack it in a 9 x 6 x 3 inch box and the dimensional weight falls to 1.17 lb. The 1.2 lb unit weight then sets the bill, and the fee drops by $0.53 a unit. On 500 units a month that is $265.
Worked model: three hypothetical products
The model below compares the per-order cost of each method for three made-up products. These are modelled numbers built to show the method, not typical results for any real product.
Assumptions, applied to all three:
- 15% referral fee (Home and Kitchen or Office Products), charged on the item price, with free shipping to the customer.
- FBA fulfillment fee from the $10 to $50 table above, plus the 3.5% surcharge.
- Each unit sits in an Amazon warehouse for 2 months before it sells. Storage at $0.78 per cubic foot per month off-peak and $2.40 at peak, the standard-size rates for the lowest storage utilization band.
- Inbound freight to Amazon of $0.50 per pound of unit weight (your own carrier cost; a hypothetical figure).
- Inbound placement fee of $0.27 a unit, the average Amazon gave for standard-size products when it introduced the fee in 2024. Your own figure may differ.
- FBM packaging of $0.40, $0.75 and $1.00 per order for the three products, plus $1.00 of labor per order to pick and pack.
Size tier and billed weight Small standard, 5 oz Large standard, 1.73 lb (dimensional) Large standard, 2.53 lb (dimensional)
Referral fee (15%) $3.00 $4.50 $6.75
FBA fee incl. 3.5% surcharge $3.57 $5.76 $6.48
Storage, 2 months $0.01 $0.22 $0.32
Inbound freight $0.16 $0.60 $1.20
Inbound placement $0.27 $0.27 $0.27
FBA total $7.01 $11.35 $15.02
FBM: referral + packaging + labour $4.40 $6.25 $8.75
Break-even label cost $2.61 $5.10 $6.27
Break-even label at peak rates $2.84 $5.89 $7.34
Hypothetical model by E-commerce Partners. Calculated in Python and re-checked with a second, independent script that searched for the break-even label cent by cent; both gave identical results.Read the bottom rows as a test. If your all-in cost for one shipping label is lower than the break-even figure, FBM is cheaper for that product. If it is higher, FBA is cheaper.
For comparison, USPS Ground Advantage retail prices effective October 4, 2026 start at $10.05 for a 1 lb parcel in Zone 1 and reach $11.70 in Zone 5 and $13.65 in Zones 8 and 9. Commercial and negotiated rates can be lower than retail, so price your own lanes. The point stands either way: an FBM seller needs heavily discounted labels to beat FBA on light, low-priced items.
Why the answer changes as the product gets bigger
The break-even label rises with size, from $2.61 for the 5 oz item to $6.27 for the 2.4 lb item. FBA fees grow slowly with weight, while your own label costs grow faster, especially across long zones. But your packaging and labor also grow, and Amazon’s storage fees start to matter once a product takes up real space.
Storage is the variable to watch. In the model, product C costs $0.32 to store for two off-peak months. If it sits for six months, that becomes about $0.95, and at peak rates the same six months would cost more than $2.90. Past 181 days, aged inventory fees can apply on top. Slow sellers, seasonal stock and bulky items are where FBM most often wins, even when the label maths says otherwise.
The costs people leave out of FBM
FBM looks cheap when you count only the label. A fair comparison also includes:
- Your time. The model uses $1.00 per order. If packing 40 orders takes you two hours, price that time at what you could earn doing something else.
- Packaging. Mailers, boxes, void fill, tape and printer labels add up per order.
- Returns. FBM sellers process returns themselves, including return labels where they pay them.
- Storage and receiving. A spare room is free until it is full. A third-party warehouse charges for receiving, storage and pick and pack.
- Sales effect. Amazon says FBA products are eligible for free two-day shipping through Prime, which it says can help conversions. That effect varies by product and cannot be modelled from fee tables, so test it rather than assume it.
The costs people leave out of FBA
- Freight into Amazon, plus prep, labelling and any third-party prep service.
- Inbound placement fees, which vary by shipment.
- The low-inventory-level fee. Amazon said when it introduced the fee that standard-size sellers can avoid it by keeping more than four weeks of inventory relative to sales. That rule pushes you to hold more stock, which raises storage.
- Peak season. From October 15 to January 14, peak fulfillment fees and higher storage rates apply. In the model, the break-even label rises by $0.23 to $1.07 per order during peak.
- Returns processing fees on products with high return rates.
How to run this for your own product
- Measure the packaged product: longest, median and shortest side in inches, and weight in ounces.
- Find the size tier. Up to 16 oz and within 15 x 12 x 0.75 inches is small standard. Up to 20 lb and within 18 x 14 x 8 inches is large standard.
- For large standard, calculate dimensional weight (L x W x H / 139) and use whichever is higher, that or unit weight.
- Look up the fulfillment fee for your price band, then add the 3.5% surcharge if it still applies to your account.
- Add storage: cubic feet (L x W x H / 1,728) x monthly rate x the months a unit typically waits.
- Add inbound freight and placement per unit from your last shipment.
- Subtract your FBM packaging and labor per order. What is left is your break-even label cost.
- Compare it with your real average label cost across the zones you ship to, not your cheapest lane, and use peak fees if most of your sales come in Q4.
- Check the result against Seller Central’s Revenue Calculator, which compares Amazon fulfillment with your own fulfillment for a given product.
Once you know the cost per order under each method, plug it into your margin before you set ad budgets. Our break-even ROAS guide shows how fulfillment costs change the return you need from ads.
When to use each, or both
- FBA tends to fit small, light, fast-selling products in the $10 to $50 band, where the fulfillment fee is low and storage barely registers.
- FBM tends to fit slow sellers, bulky or heavy items, products with long storage times, and sellers who already have discounted carrier rates or a warehouse.
- Many sellers run both. A common pattern is FBA for top sellers and FBM for the long tail, or FBM as a backup when FBA stock runs low. Amazon’s FBA page says you can select some or all of your eligible products for FBA.

Frequently asked questions
Is the referral fee different for FBA and FBM?
No. The referral fee depends on category and price, not fulfillment method. Amazon describes it as a percentage of the total price. If you charge FBM buyers for shipping, check in Seller Central how that charge is treated for your category.
Which selling plan should I pick?
Amazon’s pricing page lists two plans: Individual at $0.99 per item sold and Professional at $39.99 a month. Once you sell more than about 40 units a month, the Professional plan costs less per unit on fees alone ($39.99 / $0.99 is about 40.4 units).
What happens to these numbers during the holidays?
Peak fulfillment fees reported for 2026 apply from October 15, 2026 to January 14, 2027, and standard-size storage rises from $0.78 to $2.40 per cubic foot per month for October to December at the lowest utilization band. In the model, that makes FBM slightly more competitive.
Does this apply to Amazon.ca?
No. Amazon.ca has its own fee tables in Canadian dollars. The method is the same, but use the Canadian rate card and your Canadian carrier rates.
Where do I find my exact fees?
In Seller Central, the Fee Preview report (Reports, then Fulfillment, then Payments) and the Revenue Calculator show estimated fees per product. Amazon’s own figures override any published table, including the one in this article.
The takeaway
Work out one number for each product: the label cost at which FBM matches FBA. For light, fast-moving items it is often under $3, which few sellers can beat. For heavier or slower items it rises, and storage tips more of them toward FBM. Measure, calculate, and re-check every peak season and every January.
