An estimate from Amazon’s published rate card. It leaves out monthly storage, returns, ads, and inbound placement fees. Amazon bills on the size and weight it measures at the warehouse, which can differ from what you enter.
How Amazon’s fees actually work
Two fees decide whether an FBA unit makes money. The referral fee is Amazon’s commission on the sale. The fulfillment fee is what Amazon charges to pick, pack, and ship it. Everything else — storage, returns, advertising — sits outside the single sale and is budgeted separately.
Referral fees: a percentage, with a floor
Amazon takes a percentage of the total sales price, and the percentage depends on the category. Most categories are 15%. Consumer electronics and computers are 8%. Amazon device accessories are 45%. Whatever the percentage works out to, most categories charge a minimum of $0.30 per item, so a $1.50 sale pays the same referral fee as a $2.00 one.
Tiered categories come in two shapes, and they are easy to confuse. Some are marginal: jewelry is 20% of the first $250.00 and 5% of anything above it, so each slice bills at its own rate, like income tax. Others pick one rate for the whole price based on the band the price lands in: clothing is 5% at $15.00 or less, 10% up to $20.00, and 17% above that — and a $30 shirt pays 17% of the entire $30, not 5% of the first $15. The calculator follows Amazon’s wording for each category, which is the only way to tell the two apart.
Fulfillment fees: size tier first, then weight, then price
The fulfillment fee is not a percentage. Amazon measures the packaged unit, assigns it a size tier, and reads a fee off a table. A unit must fit every limit of a tier to earn it — one long side is enough to push it up a tier and add dollars to the fee.
Small standard bills on the unit’s own weight. Every larger tier bills the greater of the actual weight and the dimensional weight, which is length × width × height in inches divided by 139. That rule is what makes a light, bulky box expensive: a pillow that weighs 14 oz can bill as though it weighed three pounds. If you can take an inch off the box, take it.
Since 2026-01-15 the rate card prints three price columns for the same weight band: under $10.00, $10.00 to $50.00, and over $50.00. The under-$10.00 column is Low-Price FBA — the cheaper rates that apply automatically to inexpensive items, with nothing to opt into. A separate fuel and logistics surcharge of 3.5% has applied to the fulfillment fee since 2026-04-17; the published tables below, and the calculator, are the pre-surcharge rates Amazon prints.
The same date brought a Small bulky tier, sitting between Large standard and Large bulky. It matters more than it sounds: units in that range used to fall straight into Large bulky, and the new tier is over a dollar cheaper per unit. If you sell anything between 18 and 37 inches on its longest side, re-check units you priced under the old card — some of them are viable now that were not before.
Measure the box, not the product
The commonest reason a calculator disagrees with an Amazon invoice is the input, not the arithmetic. Amazon bills on the dimensions and weight it records at the fulfillment centre, measured on the packaged unit as it arrives — poly bag, box, dunnage and all. A product listed as 12 oz on the manufacturer’s spec sheet can arrive at 15 oz packaged, and that is enough to cross a weight band.
Round up when you are unsure. A fee estimate that is a few cents pessimistic costs you a marginal buy; one that is optimistic buys you a pallet of stock that loses money on every sale. If a unit only works at the exact figures you typed, it does not work.
The fee cliffs worth watching
Amazon’s fees are a staircase, not a slope. Three steps catch sellers out:
- $10.00. One cent over and the unit leaves Low-Price FBA for the standard fulfillment rate. Repricing from $10.00 down to $9.99 can genuinely earn more per unit.
- $50.00. Above it the fulfillment fee moves to the top price column.
- Category breakpoints. Clothing steps at $15.00 and $20.00, grocery at $15.00, baby and beauty at $10.00. In a band-priced category, crossing one changes the rate on the whole price.
This is why a fee quote must never be scaled from one price to another. The calculator recomputes the whole stack at whatever price you type, and warns you when a step is within two dollars.
What this calculator leaves out
A per-unit estimate cannot honestly carry costs that are not per-unit. Left out on purpose:
- Monthly storage. Charged per cubic foot per month on what is in the warehouse. Standard-size inventory runs $0.78 per cubic foot for most of the year and $2.40 during October–December; oversize runs $0.56 and $1.40. Budget it against how long the unit sits, not against the sale.
- Returns processing, charged on returned units in some categories.
- Advertising. If the unit only sells with Sponsored Products behind it, the true cost per sale is higher than anything here.
- Inbound placement fees, charged on the way in depending on how you split a shipment.
- Aged inventory surcharges and the low-inventory-level fee, both of which depend on your account’s history rather than the unit.
- The $39.99 Professional plan — a monthly subscription, not a per-unit cost.
How to check a specific ASIN on Amazon
For a product that already exists on Amazon, the definitive number comes from Amazon itself. Open the FBA Revenue Calculator and choose Continue as guest — no seller account needed. Search the ASIN and Amazon returns the fees for the catalogue’s own recorded dimensions, which beats measuring the box yourself. Use this page when there is no ASIN yet, when you are working from a spreadsheet of prospects, or when you want to see how profit moves across a price range.

FBA size tiers
Measured on the packaged unit. A unit must fit every limit in the row to qualify.
| Size tier | Max weight | Longest | Median | Shortest | Length + girth |
|---|---|---|---|---|---|
| Small standard | 1 lb | 15" | 12" | 0.75" | — |

Small bulky is new on 2026-01-15. It sits between Large standard and Large bulky and is markedly cheaper than the Large bulky rate that used to catch these units.

Apparel bills on its own, slightly higher ladder — switch the apparel toggle on the calculator to use it. One row is missing there on purpose: non-peak apparel above 3 lb, where the only published figure repeats the non-apparel base and cannot be right, so the calculator declines to price it rather than understate it.
Holiday peak runs 2026-10-15 to 2027-01-14. It is not a surcharge on these rates — Amazon swaps in a whole replacement card, and the gap runs from about $0.19 to $2.81 a unit depending on the tier. Use the peak toggle to price against it.
Questions sellers ask
- Is this FBA calculator free?
- Yes. There is no sign-up, no trial, and no limit on how many products you check. The rate card is bundled with the page and the arithmetic runs in your browser, so nothing you type is sent anywhere.
- How accurate is it?
- The referral fees come from Amazon's own pricing page and the fulfillment fees from Amazon's published US rate card, so the arithmetic is exact for the inputs you give it. The usual source of error is the inputs: Amazon bills on the size and weight it measures at the fulfillment centre, which is often larger than the seller expects. Treat the result as a close estimate, not an invoice.
- Why did my fee jump when I dropped the price to $9.99?
- It fell, not jumped. Items priced under $10.00 are fulfilled at the Low-Price FBA rates, which are cheaper than the standard rates. The catch is that the step is sharp: one cent either side of $10.00 changes the fulfillment fee. The calculator flags the boundary whenever your price is close to it.
- Does this include monthly storage fees?
- No, and that is deliberate. Storage is billed monthly on whatever is sitting in the warehouse, so it belongs to the month, not to a single sale. Folding it into one unit's profit would flatter fast sellers and punish slow ones. The rates are quoted in the guide above so you can budget for them separately.
- What is the difference between FBA and FBM here?
- Both pay Amazon's referral fee. FBA then pays Amazon a fulfillment fee based on the unit's size tier and weight. FBM pays no fulfillment fee, because you ship the order yourself — so the calculator asks for your own postage cost instead and puts that in its place.

Referral fees, minimums, and the media closing fee come from Amazon’s own pricing page. Amazon publishes the fulfillment tables inside Seller Central, which needs a login, so those rows were cross-checked across independent rate-card guides that agreed row for row. Checked 2026-09-09.

Fees are half the question
A unit can clear its fees and still be a bad buy if nobody is searching for it or the listing is suppressed. SellerAide grades listings against 80 compliance rules and turns live Amazon fees into a BUY, WAIT, or SKIP verdict.
