Free Amazon FBA calculator: 2026 fees and profit
Enter one packaged unit to see Amazon's fees and what you keep.
Amazon’s Revenue Calculator now sends you to a Seller Central sign-in. This one doesn’t. Enter the packaged size, weight, price and category to see the size tier, the 2026 fulfillment fee with the 3.5% surcharge on its own line, the referral fee, storage, and your profit, margin and ROI. Peak rates apply to shipments leaving from October 15, 2026 to January 14, 2027.
How Amazon FBA fees add up
Each unit sold through FBA pays two main fees: a referral fee to Amazon for the sale and a fulfillment fee for the pick, pack and shipping. Amazon also bills storage monthly, by cubic foot.
Fulfillment fee
Set by the size tier, the shipping weight and the price band (under $10, $10 to $50, over $50). Apparel has its own rate card. Since April 17, 2026, a 3.5% surcharge is added.
Referral fee
A percentage of the sale price, set by the category, with a minimum in most categories. It is the same whoever ships the order.
Monthly storage
Billed per cubic foot of packaged volume. October to December costs 2.5 to 3.1 times the January to September rate.
Fees that depend on you
Inbound placement, low-inventory, aged-inventory and storage-utilization fees depend on how you ship in and how fast you sell. The calculator lists them apart from the total.
2026 Amazon FBA size tiers
Amazon measures the unit in its packaging, sorts the three sides from longest to shortest, and checks them against each tier in order. The first tier the unit fits sets its rate card. A 10 × 6 × 1 in item that weighs 8 oz is large standard.
| Size tier | Longest side | Median side | Shortest side | Length + girth | Weight |
|---|---|---|---|---|---|
| Small standard | 15 in | 12 in | 0.75 in | No limit | Up to 1 lb unit weight |
| Large standard | 18 in | 14 in | 8 in | No limit | Up to 20 lb shipping weight |
| Small bulky | 37 in | 28 in | 20 in | 130 in | Up to 50 lb shipping weight |
| Large bulky | 59 in | 33 in | 33 in | 130 in | Up to 50 lb shipping weight |
| Extra-large, 0 to 50 lb | No limit | No limit | No limit | No limit | Up to 50 lb shipping weight |
| Extra-large, 50+ to 70 lb | No limit | No limit | No limit | No limit | Over 50 to 70 lb shipping weight |
| Extra-large, 70+ to 150 lb | No limit | No limit | No limit | No limit | Over 70 to 150 lb shipping weight |
| Extra-large, over 150 lb | No limit | No limit | No limit | No limit | Over 150 lb shipping weight for tier classification; fee uses unit weight |
Sizes are maximums. Length plus girth is the longest side plus twice the other two. Extra-large covers anything over the large bulky limits. Where the table says shipping weight, it is the greater of the unit weight and the dimensional weight (L × W × H ÷ 139). For the over-150-lb extra-large tier, dimensional shipping weight selects the tier while the fee formula uses unit weight.
2026 peak and non-peak FBA fee dates
The ship date picks the rate card. Peak rates are higher: the 10 × 6 × 1 in example costs $4.36 to fulfill at peak rates and $4.09 at non-peak rates, surcharge included.

What this calculator leaves out
Where Amazon’s public pages don’t give a clear number, or the fee needs your account history, the calculator leaves it out or shows a range. It doesn’t fill the gap with a guess.
- Dangerous goodsHazmat items use their own rate card, which isn't loaded. The calculator shows no fulfillment fee for them rather than a core-rate guess.
- Overmax itemsExtra-large items in the 0 to 150 lb tiers that are over 96 in long, or over 130 in length plus girth, add an Overmax fee. Amazon hasn't said whether the 3.5% surcharge applies to it, so the calculator shows a range with and without that surcharge.
- Packaging program feesShips in Product Packaging discounts and the bulky non-certified packaging charge depend on program enrollment.
- Inbound placementThe fee varies with the shipment split you choose and where inventory lands, so it shows as a range next to the total.
- Low-inventory-level feeIt needs your 30-day and 90-day supply history and exemption status, so it is left out.
- Storage-utilization surchargeIt depends on your account's storage ratio, plan age and sales volume, so it is left out.
- Aged-inventory surchargeIt depends on how long units sit at Amazon, which the calculator doesn't ask, so it is left out.
- RoundingAmazon doesn't publish one rounding rule for measurements or the surcharge. Results can differ from Amazon's by a cent or a weight band at an edge.
- Thin items under $10For large standard items under $10 and thinner than 2 in, Amazon's main rate card and its Low Price FBA page disagree about the 2 in dimensional-weight minimum. The calculator shows a range spanning both readings.
- Category exceptionsSubcategories with their own rate, like veterinary diets in Pet Supplies, aren't separate choices. Amazon's category for your ASIN decides.

Amazon FBA fee FAQs
- How much does Amazon FBA cost per unit?
- It depends on the size tier, shipping weight, price and category. A 10 × 6 × 1 in home and kitchen item that weighs 8 oz packed and sells for $25.00 is large standard. At 2026 peak rates it pays a $3.75 referral fee and a $4.36 fulfillment fee, $8.11 in all before storage. Storage, inbound shipping and your product cost come on top.
- When are Amazon's 2026 peak season FBA fees?
- Shipments leaving an Amazon fulfillment center from October 15, 2026 through January 14, 2027 use peak fulfillment fees. Shipments leaving from January 15 through October 14, 2026 use non-peak fees. The 10 × 6 × 1 in example item pays $4.36 to fulfill at peak rates and $4.09 at non-peak rates.
- What is the 3.5% FBA fuel and logistics surcharge?
- Since April 17, 2026, Amazon adds a 3.5% fuel and logistics surcharge to US FBA fulfillment fees, peak rates included. The amounts on Amazon's rate cards don't include it, so the calculator shows it as its own line.
- How does Amazon decide an item's size tier?
- From the packaged unit's longest, median and shortest sides and its weight. Small standard allows up to 15 × 12 × 0.75 in and 1 lb. Large standard allows up to 18 × 14 × 8 in and 20 lb. Anything bigger is bulky or extra-large. The calculator shows which limit your item went over.
- Does Amazon FBA use dimensional weight?
- For most tiers, yes. Large standard, bulky and extra-large items up to 150 lb pay on the greater of the unit weight or the dimensional weight, which is length × width × height in inches ÷ 139. Bulky and extra-large items count the width and height as at least 2 in. Small standard items and extra-large items over 150 lb pay on unit weight.
- What is the Amazon referral fee?
- A percentage of the sale price that depends on the category. Home and Kitchen is 15% with a $0.30 minimum. Consumer Electronics is 8% with a $0.30 minimum. Clothing and Accessories is 5% up to $15.00, 10% up to $20.00 and 17% above $20.00, on the whole price, with a $0.30 minimum. Amazon's category for your exact listing decides the rate.
- Can I use an FBA calculator without a Seller Central account?
- Yes, this one. Amazon's Revenue Calculator now sends visitors to a Seller Central sign-in page. This calculator needs no account and runs in your browser. For a live listing, the Fee Preview in Seller Central has Amazon's own number for that ASIN.
- Does the estimate include the inbound placement fee?
- Not in the total. Amazon charges it per unit when you send inventory to fewer locations, and the amount depends on where the inventory ends up. The calculator shows Amazon's published range for your item next to the total. Amazon-optimized splits, when you're offered them, have no placement fee, and extra-large items are exempt.
- What is the low-inventory-level fee?
- A per-unit fee Amazon charges when an item's 30-day and 90-day days of supply are both below 28 days. It depends on your sales history, so it isn't in the total. Amazon exempts some sellers and items, including new Professional sellers for their first 365 days and Grocery.
- How do I compare FBA with FBM or a 3PL?
- Enter what it costs you to ship one order yourself, and what your 3PL charges per order, in the comparison under the calculator. Each column is the same Amazon sale with the same referral fee. Only the fulfillment cost changes, plus FBA's storage and inbound costs.
