Amazon FBA Fee Structure for 2026 — Complete Breakdown

1. Referral Fees (Category-Based Commission)

Amazon charges a referral fee — a percentage of the total sale price — on every item sold. This is Amazon's commission for listing and selling on their marketplace. The rate varies by product category, ranging from 8% for consumer electronics to 20% for jewelry. Most categories are charged at 15%. Our calculator includes all major category rates so you can get accurate estimates for your specific product type.

Formula: Referral Fee = Sale Price × Category Rate
Example: A $29.99 home product at 15% = $4.50 referral fee

2. FBA Fulfillment Fees (Weight & Size Based)

FBA fulfillment fees cover picking, packing, shipping, and customer service for your products stored in Amazon's fulfillment centers. These fees are determined by your product's size tierand shipping weight. In 2026, Amazon increased fulfillment fees by an average of $0.08 per unit across standard-size products. Our calculator uses approximate 2026 rates across all tiers:

• Small Standard (≤ 6 oz): ~$3.22 per unit
• Large Standard (≤ 1 lb): ~$4.75 per unit
• Large Standard (1–2 lbs): ~$5.80 per unit
• Large Standard (2–3 lbs): ~$6.90 per unit
• Small Oversize: ~$8.25 per unit
• Medium Oversize: ~$11.50 per unit
• Large Oversize: ~$18.75 per unit
• Special Oversize: ~$35.00+ per unit

3. Fuel & Logistics Surcharge (New for 2026)

Starting April 17, 2026, Amazon introduced a 3.5% fuel and logistics surcharge applied to FBA fulfillment fees. This surcharge is calculated as 3.5% of the base fulfillment fee and is designed to offset rising fuel and transportation costs. Our calculator automatically includes this surcharge so you get the complete fee picture for 2026.

4. Monthly Storage Fees (Optional Consideration)

Amazon charges monthly storage fees based on the cubic footage your inventory occupies in fulfillment centers. Standard-size storage fees in 2026 range from approximately $0.87 per cubic foot (January–September) to $2.49+ per cubic foot (October–December). While this calculator focuses on per-unit fulfillment costs, storage fees are an important factor for long-term inventory planning — especially for slow-moving, oversized, or seasonal products.

Step-by-Step Calculation Examples

Example 1: Small Kitchen Gadget (Best-Selling Scenario)

Product: Garlic Press — Sale Price: $14.99, Category: Home (15%), Weight: 0.3 lbs, COGS: $4.00
Referral Fee: $14.99 × 15% = $2.25
Fulfillment Fee: $3.22 (Small Standard)
Fuel Surcharge: $3.22 × 3.5% = $0.11
Total Amazon Fees: $5.58
Net Profit Per Unit: $14.99 − $4.00 − $5.58 = $5.41
Profit Margin: 36.1%
At 500 units/month: $2,705 monthly net profit

Example 2: Electronics Accessory (High Volume)

Product: Phone Case — Sale Price: $24.99, Category: Electronics Accessories (15%), Weight: 0.4 lbs, COGS: $6.00
Referral Fee: $24.99 × 15% = $3.75
Fulfillment Fee: $3.22 (Small Standard)
Fuel Surcharge: $0.11
Total Amazon Fees: $7.08
Net Profit Per Unit: $24.99 − $6.00 − $7.08 = $11.91
Profit Margin: 47.7%
At 1,000 units/month: $11,910 monthly net profit

Example 3: Heavy Home Product (Margins Tighten)

Product: Set of Mixing Bowls — Sale Price: $39.99, Category: Home (15%), Weight: 3.5 lbs, COGS: $14.00
Referral Fee: $39.99 × 15% = $6.00
Fulfillment Fee: $8.25 (Small Oversize)
Fuel Surcharge: $0.29
Total Amazon Fees: $14.54
Net Profit Per Unit: $39.99 − $14.00 − $14.54 = $11.45
Profit Margin: 28.6%
Heavy products still profit but carry lower margins. Consider whether higher price points or bundling can improve your per-unit profitability.
