Amazon FBA fees are more complex than any other marketplace fee structure — and miscalculating them is the most common reason new FBA sellers fail to profit. This guide explains every Amazon FBA fee in plain language, with worked examples across product types and a link to our free calculator.
Amazon FBA Fees in 2026: The Four Fee Types
Amazon FBA charges sellers in four main ways. Every FBA product incurs all four to some degree.
1. Referral Fee
Amazon charges a referral fee on every sale regardless of whether you use FBA. It is a percentage of the sale price (not including shipping or taxes). Rates by category:
| Category | Referral Fee |
|---|---|
| Electronics | 8% |
| Clothing and accessories | 17% |
| Home and kitchen | 15% |
| Books | 15% |
| Toys and games | 15% |
| Jewelry | 20% (up to $250), 5% above $250 |
| Amazon device accessories | 45% |
| Most other categories | 15% |
2. FBA Fulfillment Fee
The fulfillment fee is charged per unit sold. Amazon calculates it based on the product size tier. Small standard items (under 4 oz) start at $3.06 per unit. A large standard item (1 lb) costs around $4.99. Oversized items can reach $26+ per unit.

3. Monthly Inventory Storage Fee
Amazon charges for storage space in their warehouses by the cubic foot. Standard-size products cost $0.78/cubic foot from January through September, and $2.40/cubic foot from October through December (peak season surcharge). Oversized products cost $0.56 and $1.40 respectively.
4. Long-Term Storage Fee
If your inventory sits in Amazon warehouses for 181 to 365 days, you are charged $3.80 per cubic foot or $0.10 per unit (whichever is greater). After 365 days, the fee increases to $6.90 per cubic foot or $0.15 per unit.

How to Reduce Amazon FBA Fees
- Optimise your product dimensions — reducing a product from large standard to small standard can save $1–$3 per unit in fulfillment fees.
- Manage inventory levels — avoid overstocking to prevent long-term storage fees. Use Amazon’s Inventory Health report to identify slow movers.
- Price strategically by category — for jewelry, pricing under $250 is significantly better (20% vs 5% above $250).
- Consider FBM for heavy or oversized items — fulfillment by merchant is cheaper for products where FBA fulfillment fees would eat most of the margin.
