| Category | Referral fee |

| Watches | 16% to $1,500, then 3% |
| Beauty, Health, Baby | 8% to $10, then 15% |
| Grocery | 8% to $15, then 15% |
| Furniture | 15% to $200, then 10% |

How Amazon FBA fees work in 2026
Referral fee (a percentage of the sale)
Amazon takes a referral fee on every sale, a percentage of the price set by your category. Most categories are 15%, with a $0.30 minimum. Several categories are graduated, meaning the rate changes by price band rather than applying one flat rate. The calculator computes those bands correctly, which is where flat calculators overcharge.
Why graduated categories trip up other calculators
Apparel is 5% on the first $15, 10% on the next $5, then 17% above $20. A $25 apparel item is 5% of $15 plus 10% of $5 plus 17% of $5 = $2.10, not 17% of the whole $25 = $4.25. Jewelry, beauty, baby, grocery and electronics accessories work the same way. Most calculators apply the top rate to the whole price and overstate your fee. This one does not.
FBA fulfillment fee (set by size and weight)
If Amazon fulfills the order, it charges a fixed fee set by your item's size tier and billable weight, and in 2026 also by a sale-price band: under $10, $10 to $50, and over $50, so the same item costs more to ship once you price it higher. A 3.5% fuel and logistics surcharge added in April 2026 sits on top, turning a $3.48 fee into about $3.60. The calculator detects your size tier and applies the surcharge for you.
Dimensional weight, and why a light item can cost more
Amazon does not always bill on what your item weighs on a scale; it uses the billable weight, the greater of the actual weight and the dimensional weight. Dimensional weight is length times width times height in inches divided by 139, so a big but light item like a pillow can bill well above its scale weight and jump a tier. A 12 by 9 by 3 inch box (about 30 by 23 by 8 cm) works out to roughly 2.3 lb billable. Tighter packaging can pull you under a threshold and drop a whole fee band, and the calculator flags when dimensional weight is the number that counts.
Storage and the selling plan
Inventory in Amazon's warehouses costs a monthly storage fee, about $0.78 per cubic foot most of the year and $2.40 in October to December. The Individual plan adds $0.99 per item, while the Professional plan is $39.99 a month with no per-item fee, which is cheaper once you sell more than about 40 units a month. Open the options to include these.
FBA vs FBM: which nets you more
With FBM you ship to the buyer yourself, so you skip the FBA fulfillment and storage fees but pay your own shipping. For slow-moving or bulky items, FBM often wins. The calculator runs both and tells you the winner and the exact per-unit difference, so you do not have to guess.
Worked examples, verified for 2026
Each one is computed by the same engine the calculator runs, to the cent. Fulfillment and storage are 2026 estimates, so confirm yours in Seller Central.
Home goods, $40 sale
A 1 lb item, 12 by 9 by 3 inches, in a 15% category, costing you $15 plus $2 inbound. Referral $6.00, fulfillment $6.31 with the fuel surcharge, storage $0.15, plan $0.99: $13.45 in Amazon fees. Net profit is $9.55, a 23.9% margin and a 56.2% ROI.
Apparel, $25 sale (graduated band)
Clothing at $25, 0.5 lb, costing $8 plus $1 inbound and $0.50 prep. The graduated referral is $2.10, not the $4.25 a flat 17% would charge. With $5.22 fulfillment plus storage and plan, fees are $8.38. Net profit is $7.12, a 28.5% margin and a 75.0% ROI.
FBA vs FBM, same $40 item
On FBA you net $9.55 after the $6.31 fulfillment fee. Ship it yourself for $6 and FBM nets $12.01, so FBM wins by $2.46 per unit here because you skip fulfillment and storage. Fast, small items usually flip the verdict back to FBA.
Price for profit: ROI, margin and paying less
ROI vs profit margin, and why sellers mix them up
Margin and ROI answer two different questions, so the calculator shows both. Profit margin is net profit divided by the sale price, the share of the price you keep. ROI is net profit divided by what you put into the unit, the product cost plus inbound shipping plus prep, so it shows how hard your money is working. Take the apparel example above: $7.12 net on a $25 sale is a 28.5% margin, but against the $9.50 you had invested it is a 75% ROI. A thin margin can still be a strong ROI when your cost was low, which is why flippers chase ROI while a brand watches margin.
How to pay less in Amazon FBA fees
Most FBA fees move with size and speed, so a few habits protect your margin. Tighter packaging lowers your dimensional weight and can drop the fulfillment fee a whole band. Watch the over-$50 fulfillment price band, where pricing higher quietly raises what Amazon charges to ship. Sell through stock before the long-term storage and aged-inventory fees hit, and keep enough on hand to dodge the low-inventory fee. Pick your plan by volume, since Professional pays off past about 40 units a month. And for apparel and shoes, fewer returns means fewer returns-processing fees.
Amazon FBA calculator FAQ
How much does Amazon FBA cost per sale in 2026?
Three main fees: a referral fee (usually 15% of the price), an FBA fulfillment fee set by your item's size and weight plus a 3.5% fuel surcharge, and a monthly storage fee. On a typical $30 product these add up to roughly $8 to $10. Your actual net also depends on your product cost, inbound shipping and ad spend, which the calculator includes.
Do I need an ASIN to use this calculator?
No. Unlike Amazon's own FBA Revenue Calculator and tools like Helium 10 and AMZScout, this one takes manual numbers. You do not need an ASIN, a login, or a browser extension, so you can check a product's profit before you even source it.
What is the Amazon referral fee and how is it calculated?
It is a percentage of the total sale price, set by category, with a $0.30 minimum. Most categories are 15%. Some are graduated: apparel is 5% to $15, 10% to $20, then 17%, so a $25 item is $2.10, not $4.25. Media items add a flat $1.80 closing fee on top of the 15%.
How is the FBA fulfillment fee calculated?
By your item's size tier and billable weight, where billable weight is the greater of actual weight and dimensional weight (length × width × height ÷ 139). In 2026 the fee also varies by sale-price band, and a 3.5% fuel surcharge is added. These cents drift, so the calculator labels them estimates; confirm yours in Amazon's revenue calculator.
What is my breakeven price on Amazon?
The lowest price at which you do not lose money, once the referral fee, fulfillment fee and your costs are covered. The calculator solves it for you and shows it next to your margin, so you know your price floor before you list. It also reverses the math: enter a target margin and it returns the price to charge.
Is FBA or FBM cheaper for my product?
It depends on size, weight and how fast it sells. FBA charges fulfillment and storage but handles shipping; FBM skips those but you pay to ship to the buyer. Bulky or slow items often net more on FBM. The calculator computes both and shows which nets you more per unit.
How much does Amazon take from a $30 sale?
On a standard $30 item in a 15% category, the referral fee is $4.50 and a small-standard fulfillment fee is around $3.50 with the fuel surcharge, so Amazon takes roughly $8, or about 27%. Subtract your product cost, inbound shipping and ads to get your real net profit, which the calculator shows.
Are these the current 2026 Amazon fees?
The referral percentages are the 2026 schedule and have been stable since 2024. The fulfillment and storage figures use the 2026 structure including the April 2026 fuel surcharge, but Amazon revises those cents, so they are labeled estimates with an as-of date. Always confirm your exact fulfillment fee in Seller Central before pricing.
How do I use the Amazon FBA calculator?
Enter your sale price and product cost, pick the category, then add the weight and box size so the tool finds your size tier. Add inbound shipping, prep and ad spend, and it returns net profit, margin, ROI and breakeven. There is no ASIN or login, so you can run the numbers before you source.
What is the Amazon FBA fuel surcharge in 2026?
A 3.5% fuel and logistics surcharge that Amazon added to US FBA fulfillment fees in April 2026. It multiplies the published fulfillment fee by 1.035, so a $3.48 fee becomes about $3.60. The calculator includes it; a calculator that leaves it out is understating your fee.
How do I calculate my profit and ROI on Amazon FBA?
Net profit is your sale price minus Amazon's fees (referral, fulfillment, storage, plan) and your own costs (product, inbound shipping, prep, ads). Margin is that net divided by the sale price; ROI is the net divided by what you invested in the unit. The calculator shows all of them next to your breakeven price.
How much is Amazon storage per cubic foot?
About $0.78 per cubic foot for standard-size items most of the year, rising to $2.40 from October to December when warehouse space is tight. Oversize items cost less per cubic foot. The calculator works it out from your box size and how many months you store.
