What are Amazon FBA fees in 2026?

Amazon FBA fees include: (1) Referral fee 8–15% of sale price by category, (2) Fulfillment fee based on product size/weight starting around $3.22 for small standard, (3) Storage fee $0.87/cubic foot Jan–Sep and $2.40 Oct–Dec, (4) Optional fees for removals, returns processing, and long-term storage.

How is the Amazon referral fee calculated?

The referral fee is a percentage of your total sale price including item price and shipping. Rates vary by category: most categories are 15%, some are 8% (computers, consumer electronics), and a few specialty categories have different rates. There's also a minimum referral fee of $0.30 per item.

What size tier is my product for FBA?

Amazon classifies products into Small Standard (15×12×0.75 in, under 12 oz), Large Standard (18×14×8 in, under 20 lbs), Small Oversize, Medium Oversize, Large Oversize, and Special Oversize. Use Amazon's official size-tier chart in Seller Central to determine your product's classification before pricing.

How can I reduce my Amazon FBA fees?

Optimize product packaging to fit smaller size tiers. Use Amazon's Inventory Placement Service strategically. Monitor your Inventory Performance Index (IPI) to avoid storage limits. Remove slow-moving inventory before long-term storage fees apply. Consider FBA Small and Light for items under $12.

What is the difference between FBA and FBM fees?

FBA (Fulfillment by Amazon) includes storage, picking, packing, shipping, and customer service fees but offers Prime eligibility. FBM (Fulfillment by Merchant) has no Amazon fulfillment fees but you handle all shipping and customer service. FBM is often cheaper for large, heavy, or slow-moving items. Compare your true profit margin under both models before deciding.

How to Use

Enter the Amazon selling price (including any shipping you charge buyers).
Enter your landed product cost (manufacturing + inbound shipping to Amazon).
Enter the FBA fulfillment fee for your product's size tier (look it up in Seller Central or use $5.40 as a starting estimate for standard size).
Set the referral fee for your category (default 15%, electronics 8%). Then calculate your net profit margin and plan your promotional pricing for launches.

Formula Explained

Net Profit = Selling Price − Product Cost − (Selling Price × Referral % / 100) − FBA Fee

Referral Fee: = Percentage Amazon charges per sale, varies by category (most are 15%)
FBA Fee: = Flat fulfillment fee based on size tier and weight
Product Cost: = Your landed cost: COGS + inbound shipping to Amazon warehouses

Worked example: Sell at $30, cost $10, FBA fee $5.40, referral 15%. Referral = $30 × 0.15 = $4.50. Net = $30 − $10 − $4.50 − $5.40 = $10.10 (33.7% margin).
