Amazon's fees and your profit per unit on the 2026 US rate card, from your price, cost and box size.
Fees as of 10 November 2026, from Amazon's FBA rate card, referral fees and storage pages, with the 3.5% surcharge in force since April 17, 2026.
A $12.99 deck of cards in a 3.7 × 2.8 × 0.87 inch box pays Amazon $3.86 to pick, pack and ship and $1.95 in referral fee: 44.7% of the price before the cards are printed, and $4.11 for fulfilment between October 15 and January 14. Enter your own price, cost and box in the calculator above. It applies Amazon's published US rate card and shows what is left per unit.

It works out the five lines Amazon charges on a typical FBA unit and what that leaves you: the size tier your box falls in, the FBA fulfilment fee for that tier and price, the referral fee for your category, an estimate of monthly storage, and the total. Against your product cost, inbound shipping and advertising it then shows profit per unit, margin, return on the money tied up in stock, the break-even ACOS and, if you give it a monthly volume, profit per month.
The fee tables are Amazon's own US rate cards for three periods: 2026 non-peak (January 15, 2026 to October 14, 2026), the 2026 holiday peak (October 15, 2026 to January 14, 2027) and 2027 non-peak (from January 15, 2027). The calculator opens on whichever is in force today.
It leaves out what depends on your account rather than your product: the inbound placement fee, the low-inventory-level fee, the storage utilisation surcharge, aged-inventory charges, returns processing, removals and the lithium-battery fee. When your box is big enough to attract an oversize handling fee, the calculator says so but does not add it. Treat the profit it shows as a ceiling, as we do on every case study.
Amazon sorts every packaged unit into a size tier using its three sides and its shipping weight, and the tier sets which fee table applies. A product fits the first tier whose limits it does not exceed. The thin edge matters most: a box 0.87 inches deep misses small standard's 0.75 inch limit and pays large-standard rates, however light it is.
| Size tier | Max shipping weight | Longest side | Median side | Shortest side | Length + girth |
|---|---|---|---|---|---|
| Small standard | 16 oz | 15 in | 12 in | 0.75 in | — |
| Large standard | 20 lb | 18 in | 14 in | 8 in | — |
| Small bulky | 50 lb | 37 in | 28 in | 20 in | 130 in |
| Large bulky | 50 lb | 59 in | 33 in | 33 in | 130 in |
| Extra-large (oversize) | over any bulky limit | over 59 in | over 33 in | over 33 in | over 130 in |
Shipping weight is the unit weight for small standard. For every other tier it is the greater of the unit weight and the dimensional weight, which is length × width × height in inches divided by 139; for bulky and oversize items Amazon assumes a width and height of at least 2 inches. A light product in a big box is charged as if it were heavy. From January 15, 2027 the bulky tiers split into four and the extra-large tiers become six oversize tiers; the calculator uses the new tiers when you pick 2027 non-peak.
Within a tier the fee steps up with shipping weight, and it also depends on the price. A unit under $10 gets the low-price rate, one between $10 and $50 (both inclusive) the standard rate, and one over $50 a higher rate. These are Amazon's 2026 non-peak rates for some common weights, before the surcharge:
| Shipping weight | Under $10 | $10 to $50 | Over $50 |
|---|---|---|---|
| Small standard, 2+ to 4 oz | $2.49 | $3.42 | $3.68 |
| Small standard, 6+ to 8 oz | $2.66 | $3.54 | $3.80 |
| Large standard, 4 oz or less | $2.91 | $3.73 | $3.99 |
| Large standard, 4+ to 8 oz | $3.13 | $3.95 | $4.21 |
| Large standard, 12+ to 16 oz | $3.78 | $4.60 | $4.86 |
| Large standard, 1+ to 1.25 lb | $4.22 | $5.04 | $5.30 |
| Large standard, 1.75+ to 2 lb | $5.00 | $5.82 | $6.08 |
| Large standard, 2.75+ to 3 lb | $5.85 | $6.67 | $6.93 |
Between October 15, 2026 and January 14, 2027 the holiday peak card applies instead, which is higher on every row. The same deck that pays $3.86 the rest of the year pays $4.11 in peak. Since April 17, 2026 Amazon has also added a 3.5% fuel and logistics surcharge to every fulfilment fee. It is not printed in the rate tables, so the calculator applies it on top.
Dropping the deck to $9.99 moves it into the low-price band, where fulfilment falls to $3.01. Through January 14, 2027 every category qualifies. From January 15, 2027 these fee categories lose the low-price rate and pay the $10 to $50 rate instead: Automotive and Powersports, Compact Appliances, Musical Instruments and AV Production, Media - Books, DVD, Music, Software, Video, Computers.
The referral fee is Amazon's commission on the sale: a percentage of the total price the customer pays, or a per-unit minimum, whichever is greater. Most categories charge 15%. A few charge less on cheap items (Beauty, Health and Personal Care and Baby Products take 8% at $10 or less), and some charge a lower rate only on the part of the price above a threshold. Your fee category can differ from the category the product shows in on Amazon.

Storage is charged per cubic foot of packaged volume, per month. The calculator uses Amazon's base rate for stock under 181 days old: $0.78 per cubic foot for standard-size items from January to September and $2.40 from October to December, and $0.56 and $1.40 for bulky and oversize items. Dangerous goods pay more. Sellers who have been shipping for over a year and hold a lot of slow stock also pay a utilisation surcharge, which the calculator leaves out because it depends on your whole inventory rather than one product.
Measure the packaged unit and weigh it, find its size tier, then read the fulfilment fee for that tier, shipping weight and price band off Amazon's rate card and add the 3.5% surcharge. Add the referral fee for your category and a month or two of storage. The calculator above does all of it from five numbers: price, length, width, height and weight.
Total Amazon fees per unit are the FBA fulfilment fee plus the referral fee plus storage, plus a $1.80 closing fee on media. A Professional selling plan adds $39.99 a month, which is not per unit and is not in the calculator. Inbound placement, returns and advertising are separate costs you set or incur yourself.
Products priced under $10 get the low-price FBA rates, which are lower than the $10 to $50 rates for the same box. For example, a large-standard unit of 4 oz or less costs $2.91 under $10 and $3.73 at $10 to $50 on the 2026 non-peak card, before the surcharge. From January 15, 2027 five fee categories no longer qualify.
Both. It totals Amazon's fees, then subtracts your product cost, inbound shipping and advertising to give profit per unit, margin, ROI, the break-even ACOS and monthly profit.
Break-even ACOS is the share of the sale price you could spend on advertising and still make nothing: profit before advertising divided by price. If your ACOS on a campaign is below it, each ad-driven sale makes money; above it, each one loses money.
Amazon charges holiday peak fulfilment fees from October 15, 2026 to January 14, 2027, and monthly storage roughly triples from October to December. The fee is set when the unit ships, so an order placed before October 15, 2026 that ships after it pays the peak rate.
No. Inbound placement, the low-inventory-level fee, returns processing, removals, the storage utilisation surcharge and aged-inventory charges depend on how you ship and how your stock moves, not on the product, so they are left out. The profit shown is the most a unit can make, not a guarantee.
