Amazon FBA Fees 2026: Fee Chart, Calculator and Unit Margin

October 14, 2026 · Selling products and running the numbers

Amazon FBA fees come in three layers: a referral fee (a share of the sale price, 15% in many categories), a fulfillment fee per unit set by size tier, shipping weight and price band, plus a 3.5% fuel and logistics surcharge, and a monthly storage fee per cubic foot. On an illustrative $24.99 unit that costs $6.00 to make and weighs 14 oz packed, Amazon’s fees come to $8.60 off-peak and you keep $10.39, not the $18.99 that price minus cost suggests. From October 15 the holiday rate card applies and the same unit keeps $9.91.

The FBA fee formula

referral    = sale price x referral rate   (minimum $0.30)
fulfillment = rate card fee for tier, weight and price band x (1 + 3.5%)
storage     = cubic feet x monthly rate x months the unit sits in stock

you keep    = sale price - cost of goods - referral - fulfillment - storage

Three things in that formula are easy to get wrong:

On top of these, a Professional selling plan costs $39.99 a month (or $0.99 per item sold on the Individual plan), and media items carry a $1.80 closing fee.

Amazon FBA fees chart for 2026

Amazon’s US fulfillment fees for standard-size items that are not apparel or dangerous goods, as published (the 3.5% surcharge is not included in these figures; multiply by 1.035 to get what you pay). Off-peak runs January 15 to October 14, 2026; holiday peak runs October 15, 2026 to January 14, 2027.

Size tier, shipping weight Under $10 $10-$50 Over $50 Holiday peak, $10-$50
Small standard, up to 2 oz $2.43 $3.32 $3.58 $3.51
Small standard, 2 oz+ to 4 oz $2.49 $3.42 $3.68 $3.61
Small standard, 4 oz+ to 6 oz $2.56 $3.45 $3.71 $3.65
Small standard, 6 oz+ to 8 oz $2.66 $3.54 $3.80 $3.74
Small standard, 8 oz+ to 10 oz $2.77 $3.68 $3.94 $3.89
Small standard, 10 oz+ to 12 oz $2.82 $3.78 $4.04 $3.99
Small standard, 12 oz+ to 14 oz $2.92 $3.91 $4.17 $4.13
Small standard, 14 oz+ to 1 lb $2.95 $3.96 $4.22 $4.18
Large standard, up to 4 oz $2.91 $3.73 $3.99 $3.97
Large standard, 4 oz+ to 8 oz $3.13 $3.95 $4.21 $4.21
Large standard, 8 oz+ to 12 oz $3.38 $4.20 $4.46 $4.48
Large standard, 12 oz+ to 1 lb $3.78 $4.60 $4.86 $4.89
Large standard, 1 lb+ to 1 lb 4 oz $4.22 $5.04 $5.30 $5.34
Large standard, 1 lb 4 oz+ to 1 lb 8 oz $4.60 $5.42 $5.68 $5.73
Large standard, 1 lb 8 oz+ to 1 lb 12 oz $4.75 $5.57 $5.83 $5.89
Large standard, 1 lb 12 oz+ to 2 lb $5.00 $5.82 $6.08 $6.15
Large standard, 2 lb+ to 2 lb 4 oz $5.10 $5.92 $6.18 $6.29
Large standard, 2 lb 4 oz+ to 2 lb 8 oz $5.28 $6.10 $6.36 $6.49
Large standard, 2 lb 8 oz+ to 2 lb 12 oz $5.44 $6.26 $6.52 $6.66
Large standard, 2 lb 12 oz+ to 3 lb $5.85 $6.67 $6.93 $7.08
Large standard, 3 lb+ to 20 lb $6.15 + $0.08/4 oz $6.97 + $0.08/4 oz $7.23 + $0.08/4 oz $7.51 + $0.08/4 oz

Small standard means up to 16 oz and no bigger than 15 x 12 x 0.75 inches. Anything thicker than three-quarters of an inch is large standard (up to 20 lb and 18 x 14 x 8 inches), whatever it weighs. For large standard, Amazon charges on the greater of unit weight and dimensional weight, so a light item in a big box can be billed as a heavier one.

Monthly storage for standard-size items is $0.78 per cubic foot from January to September and $2.40 from October to December, for sellers below Amazon’s storage-utilization surcharge thresholds.

These figures come from Amazon’s seller pricing page, the 2026 US FBA fulfillment fee changes page and the monthly inventory storage fees page, checked on October 13, 2026. Amazon revised the rate card for 2026 and added the surcharge in April, so confirm against those pages before relying on any figure here.

Worked example: one $24.99 unit

An illustrative Home and Kitchen item (15% referral), 14 oz packed in a 8 x 6 x 2 inch box. The box is thicker than 0.75 inches, so it is large standard; its dimensional weight is 11.1 oz, under its 14 oz weight, so it is billed on 14 oz. It takes up 0.056 cubic feet, and each unit spending about 2 months in Amazon’s warehouse before it sells:

Line Off-peak (Jan 15 - Oct 14) Holiday peak (Oct 15 - Jan 14)
Sale price $24.99 $24.99
Referral fee (15%) $3.75 $3.75
Fulfillment fee + 3.5% surcharge $4.76 $5.06
Storage (0.056 cu ft x 2 months) $0.09 $0.27
Amazon fees $8.60 $9.08
Cost of goods $6.00 $6.00
You keep $10.39 $9.91
Margin 41.6% 39.7%

Off-peak, Amazon’s three fees take 34.4% of the sale price. The biggest line is not the referral fee: it is fulfillment, $4.60 on the rate card, $4.76 with the surcharge. The holiday card raises that to $5.06 ($4.89 before surcharge), and storage at the October to December rate roughly triples, so the same unit keeps $0.48 less from October 15.

Weight is a staircase, not a slope

Same unit, same price, off-peak. Only the packed weight changes:

Packed weight Fulfillment fee (with surcharge) Total Amazon fees You keep
12 oz $4.35 $8.18 $10.81
1 lb $4.76 $8.60 $10.39
1 lb 1 oz $5.22 $9.05 $9.94
1 lb 4 oz $5.22 $9.05 $9.94
2 lb $6.02 $9.86 $9.13
2 lb 1 oz $6.13 $9.96 $9.03
3 lb $6.90 $10.74 $8.25
3 lb 1 oz $7.30 $11.13 $7.86

Within a weight bracket the fee does not move at all - 1 lb 1 oz and 1 lb 4 oz cost the same. At the bracket edge it jumps. One ounce over a pound costs $0.46 a unit; one ounce over 3 lb costs $0.40; one ounce over 2 lb only $0.11. The steps are uneven, so the bracket edge that matters is the one nearest your product.

Dimensions matter as much as weight. An 8 oz item that fits under 0.75 inches thick ships as small standard for $3.66 (with surcharge, $10-$50 band); the same weight in a 8 x 6 x 1.25 inch box is large standard at $4.09, a difference of $0.43 on every unit. Packaging is a fee decision.

The price-band cliff at $10

This is the non-obvious one. Because the fulfillment fee now depends on the sale price, crossing $10 can lose money. Take an illustrative item that costs $3.00, weighs 8 oz packed and is large standard:

Priced at $9.99 Priced at $10.00
Fulfillment fee (with surcharge) $3.24 $4.09
You keep $2.20 $1.36

Raising the price by one cent costs $0.84 per unit. To keep as much as you did at $9.99, the price has to reach $10.99. Anything between those two prices earns less than $9.99 does. The $50 edge works the same way but is gentler: crossing it adds $0.27 to the fulfillment fee of the 14 oz example unit.

Pricing for a target margin

Since the referral fee is a share of price, solve for the price rather than marking cost up:

price = (cost + fulfillment + storage) / (1 - referral rate - target margin)

For the $24.99 unit’s costs at a 25% margin: fixed costs are $10.85 (cost of goods, fulfillment with surcharge, off-peak storage), and 1 - 15% - 25% is 60%, so the price is $18.08, which delivers 25.0%. Check that the answer lands in the price band whose fulfillment fee you used; this one does.

The markup shortcut - cost divided by (1 - 25%) - gives $8.00. At that price the unit drops into the under-$10 band and still loses $3.20 per sale once fees are paid. The shortcut ignores every Amazon fee. The Etsy fee calculator post works the same backward pricing for a marketplace with flat fees per order.

Storage: small per unit until stock stops moving

At 2 months, storage is the smallest line in the example. It grows with time on the shelf: a unit of this size that sits through the whole October to December quarter pays $0.40 in storage, or 1.6% of its price, before counting any other fee. Slow sellers in the holiday quarter are where storage starts to bite, and long-held stock can also attract Amazon’s aged inventory surcharge, which is not modeled here.

How these were calculated

Fees were taken from Amazon’s US seller pricing page and Seller Central help pages (checked October 13, 2026): the referral rate for 15% categories with its $0.30 minimum, the 2026 non-peak and holiday peak fulfillment rate cards for standard-size, non-apparel, non-dangerous goods, the 3.5% fuel and logistics surcharge applied to fulfillment fees since April 17, 2026, and base monthly storage rates. Each fee line is rounded to the cent for display; totals are computed from unrounded fees. Amazon’s own rounding of the surcharge may differ by a cent. Not included: the selling plan, advertising, returns, inbound shipping to Amazon, removal and disposal fees, the storage-utilization surcharge, the aged inventory surcharge and any new-seller fee credits. Every figure on this page was computed twice - once by the code behind the product below and once by an independent implementation written from Amazon’s published schedule - and the two agree to the cent. The product, cost and weight are illustrative, not typical. This is not financial, legal or tax advice. For your exact numbers, Amazon’s Revenue Calculator uses your real dimensions and category.

If you want to run this arithmetic across your own products - cost, packed weight, box dimensions, months of stock and a target margin - the kit below lays out the fee stack and the target-margin price as a worksheet and a spreadsheet that works out the size tier and looks up this rate card. Check its rate card against Amazon’s current figures from the pages above before you rely on it.
