What Are Amazon FBA Fees?
Amazon FBA fees are charges sellers pay for using Amazon’s fulfillment service. Amazon charges these fees to cover the costs of warehousing, order processing, shipping, and customer service.
The primary fee categories comprise fulfillment fees, storage fees, and referral fees, each serving distinct operational aspects of the Amazon marketplace.
Three FBA Fees All Amazon Sellers Must Pay
These three core fees form the foundation of Amazon’s FBA pricing structure and significantly impact your bottom-line calculations. Understanding each fee type helps you price products competitively while maintaining healthy profit margins.
Every Amazon seller using FBA must pay these core fees:
1. Fulfillment Fees: Charged per unit for the cost of picking, packing, and shipping orders to customers.
2. Storage Fees: Monthly charges based on the cubic footage your inventory occupies in Amazon warehouses.
3. Referral Fees: A Percentage of each sale is paid to Amazon for marketplace access and transaction processing.
These fees work together to create your total Amazon selling costs, making accurate calculations essential for profitable operations.
1. Amazon FBA Fulfillment Fees: Cost Per Unit Breakdown
Fulfillment fees represent the highest variable cost for most sellers, directly affecting per-unit profitability on every order processed through FBA.
Amazon categorizes products into standard-size and oversized classifications, with fees calculated based on weight and dimensional measurements. Recent seller data indicate that fulfillment costs have increased by an average of 12-18% for standard-size items and up to 24% for oversized products.
Peak season surcharges apply during high-demand periods, typically from October through January, adding extra costs during the busiest selling months.
| Product Size | Weight Range | Fulfillment Fee Range |
|---|---|---|
| Small Standard | 0.5 oz – 1 lb | $3.22 – $4.75 |
| Large Standard | 1+ lb – 20 lb | $4.75 – $18.30 |
| Large Standard | 20+ lb – 70 lb | $18.30 – $89.98 |
| Oversize | 70+ lb – 150 lb | $89.98 – $195.50 |
This pricing structure rewards sellers who optimize packaging and product dimensions, as smaller, lighter items cost significantly less to fulfill than bulky alternatives.
2. Amazon FBA Storage Fees: Monthly Cost And Calculations
Storage fees accumulate monthly and can quickly impact profitability if inventory levels aren’t managed properly, especially during peak season pricing periods.
The 2025 storage fee for standard-size products is $0.78 per cubic foot per month during the off-peak season (January to September).
Peak season rates from October through December nearly double these costs, encouraging sellers to maintain leaner inventory during high-demand periods. Long-term storage fees apply to items stored longer than 365 days, adding substantial costs for slow-moving inventory.
| Product Size | Off-Peak (Jan-Sep) | Peak (Oct-Dec) |
|---|---|---|
| Standard-size | $0.78 per cubic foot | $2.40 per cubic foot |
| Oversize | $0.78 per cubic foot | $2.40 per cubic foot |
The significant peak season increase motivates sellers to carefully time their inventory shipments, avoiding excess stock during the most expensive storage months.
3. Amazon Referral Fees: How Much Amazon Takes From Each Sale
Referral fees represent Amazon’s commission for providing marketplace access, payment processing, and customer acquisition services to sellers.
- Category-Based Percentage Structure: Referral fees vary by product category, ranging from 5% to 45%, with most categories falling between 8% and 15% of the total sale price, including shipping and gift wrapping.
- Media Item Flat Fees: Books, music, and video products pay flat fees ranging from $1.35 to $1.80 per item instead of percentage-based rates.
- Minimum Fee Protection: Amazon charges a minimum referral fee of $0.30 per item, protecting sellers of very low-priced products from excessive percentage costs.
- Variable Closing Fees: Certain media categories include additional variable closing fees based on format and product type.
These fees directly reduce your profit margin on each sale, making category selection crucial for maintaining healthy business economics.
Individual Per-Item Fees Or Subscription Fees
Amazon offers two selling plans that affect your fee structure and available selling tools.
| Plan Type | Cost Structure | Best For |
|---|---|---|
| Individual | $0.99 per item sold | Sellers with fewer than 40 monthly sales |
| Professional | $39.99 monthly subscription | High-volume sellers needing advanced tools |
Professional sellers save money when selling more than 40 items monthly while gaining access to bulk listing tools, advertising options, and detailed analytics. Understanding these fee structures helps sellers make informed decisions about their business model and potential earnings as Amazon FBA sellers.
