How the FBA calculator works
The calculator works out each fee from Amazon’s 2026 US rate card, then subtracts your costs. Every rate is a default you can override, so this FBA calc stays useful when Amazon changes its fees.
Referral fee
referral = price × category rate (min $0.30)Most categories pay 15% of the sale price. Some use tiers, such as Clothing at 5%, 10% or 17% depending on price.
FBA fulfillment fee
FBA fee = rate card [size tier, weight, price] × 1.035Find the size tier and shipping weight band in the 2026 rate card, then add the 3.5% fuel and logistics surcharge.
Monthly storage
storage = cu ft × $0.78 (Jan–Sep) or $2.40 (Oct–Dec)Standard-size rates shown. Large bulky items use the oversize rates of $0.56 and $1.40 per cubic foot.
Profit, margin and ROI
profit = price − cost − inbound − referral − FBA fee − storageMargin is profit ÷ price. ROI is profit ÷ (product cost + inbound shipping). Monthly profit is profit × units per month.

Frequently asked questions
How much are Amazon FBA fees in 2026?
Expect a 15% referral fee in most categories plus a fulfillment fee from $3.32 per unit. Small standard items priced $10–$50 pay $3.32 to $3.96, large standard items start at $3.73, and large bulky items pay $9.35 plus $0.38 per lb. Storage costs $0.78 per cubic foot per month from January to September. A 3.5% fuel and logistics surcharge applies to fulfillment fees from April 17, 2026.
How is the FBA fulfillment fee calculated?
Amazon sets the FBA fulfillment fee by size tier, shipping weight and price. Find the tier (small standard, large standard or large bulky) and the weight band, then the price band. Items under $10 pay less, and standard-size items over $50 pay $0.26 more. Large standard items are priced in 4 oz steps up to 3 lb, then add $0.08 per 4 oz. From April 17, 2026, multiply the fee by 1.035 for the surcharge.
Is FBA or FBM cheaper?
FBA is cheaper when your own cost to ship one order is higher than Amazon’s fulfillment fee, storage and the cost of sending stock to Amazon. Both pay the same referral fee. A 12 oz large standard item at $24.99 costs about $4.85 per unit in FBA fees and storage, plus inbound shipping, so FBM wins only if you ship it for less than that total.
Does this FBA calculator include peak-season fees?
No. Amazon’s peak-season fulfillment fees apply from October 15, 2026 to January 14, 2027, and this calculator uses the regular 2026 rates. It does switch storage to $2.40 per cubic foot for standard-size items when you pick October to December. For Q4 sales, type the peak fee into the fulfillment fee field as an override.
Can I use it as an FBA revenue calculator?
Yes. Enter units per month and the calculator shows monthly revenue (price × units) and monthly profit after Amazon fees. It leaves out advertising, returns, the $39.99 monthly Professional plan and income tax. Subtract those yourself to turn it into a full FBA estimator of take-home profit.
