2026 Amazon FBA Fees Explained
Amazon charges sellers multiple fees that combine to determine your actual profitability. Specifically, understanding each fee helps you make better product selection decisions:
Amazon Referral Fee
A percentage of the selling price charged for every sale. This ranges from 6% (Grocery) to 20% (Jewelry). Most categories are 15%. This is unavoidable on Amazon — whether you use FBA or ship yourself (FBM). Our calculator uses the exact 2026 rate for your selected category.
FBA Fulfillment Fee
Charged per unit shipped from Amazon’s warehouse to the customer. The fee depends on your product’s size tier. Small Standard (under 1lb) starts at $3.06. Large Standard (1-20lb) ranges from $4.25-$8.90. Large Bulky starts at $9.61. Reducing your product’s weight or dimensions can move it to a lower tier and save money per unit.
FBA Storage Fee
Charged monthly based on the cubic feet your inventory occupies in Amazon’s warehouse. Standard rate is $0.87/cubic foot (January-September) and $2.40/cubic foot (October-December — Q4 season). Our tool calculates this based on your product dimensions and storage months.
Inbound Shipping
The cost to ship your inventory from your supplier (usually China) to Amazon’s fulfillment center. This is typically $1-3 per unit depending on weight and shipping method (sea vs air). Use our word counter tool when writing shipping instruction documents for your supplier.
FBA vs FBM — Which Is Better?
Our calculator compares FBA (Amazon Fulfillment) and FBM (Fulfilled by Merchant) side by side. In general:
- FBA is better when — your product is lightweight (low FBA fee), you want the Prime badge, you’re scaling volume, and your FBA fee is less than your self-ship cost
- FBM is better when — your product is heavy (high FBA fee), you have low volume and high storage costs, or you want more control over packaging and shipping
- For most new sellers — FBA is recommended for the Prime badge advantage and simplified operations
Amazon FBA Size Tiers — How They Affect Your Profit
Amazon’s size tier system directly determines your FBA fulfillment fee. Understanding tiers helps you optimize product sourcing and packaging:
- Small Standard — under 1lb (454g). FBA fee starts at $3.06. Most profitable tier. Target this when possible.
- Large Standard — 1-20lb. FBA fee $4.25-$8.90+. Common for home goods and kitchen products.
- Large Bulky — oversized items, FBA fee $9.61+. Only viable with high selling prices ($40+).
- Special Oversize — very large items. FBA fee $89.98+. Avoid for new sellers.
Our calculator automatically detects your size tier from the weight and dimensions you enter, and provides specific tips on how to reduce to a lower tier to save on fees. Combine this knowledge with our password generator to secure your Amazon Seller Central account properly.
What Is a Good Profit Margin for Amazon FBA?
According to experienced Amazon sellers and FBA experts, here are the target margins for different business scenarios:
- Minimum viable — 15% margin (below this, FBA is usually not worth the risk)
- Good — 20-30% margin (sustainable, allows for PPC spending)
- Excellent — 30-50% margin (scale aggressively with PPC and new variations)
- Outstanding — 50%+ margin (private label products with strong branding)
Furthermore, ROI (Return on Investment) is equally important for FBA sellers. Target minimum 50% ROI — meaning for every $100 you invest in inventory, you make $50 profit. Higher ROI means faster cash flow for scaling.
How to Find Profitable Amazon Products

Amazon FBA costs include: Referral fee (6-20% of selling price by category), FBA fulfillment fee ($3.06-$9.61+ based on size/weight), monthly storage ($0.87/cu ft standard, $2.40/cu ft Q4), and optional costs like inbound shipping and PPC. Our free Amazon FBA calculator automatically calculates all 2026 fees based on your product details.
FBA (Fulfilled by Amazon) means Amazon stores, packs, and ships your products. You pay FBA fees but get the Prime badge and Amazon’s customer service. FBM (Fulfilled by Merchant) means you store and ship yourself. No FBA fees but also no Prime badge. Our calculator compares both side-by-side for your specific product.
For Amazon FBA, a minimum of 20% net profit margin is recommended. Margins of 25-35% are good and allow for PPC advertising. Above 35% is excellent and allows aggressive scaling. Below 15% is generally not viable for FBA due to the risk of returns, storage fees, and price competition.
Enter your product details in our free Amazon FBA calculator: selling price, product cost, category, weight, and dimensions. The tool automatically calculates referral fee (category %), FBA fulfillment fee (based on size tier), storage fee (based on cubic feet × months), and all other costs. The result shows your exact net profit, margin, and ROI.
Amazon categorizes products into size tiers that determine FBA fees. Small Standard (under 1lb, small dims): $3.06+. Large Standard (1-20lb): $4.25+. Large Bulky (oversized): $9.61+. Reducing your product’s weight or dimensions to fit a smaller tier can save significant money per unit. Our calculator automatically detects your tier.
