Amazon charges several fees that eat into your margins. Here's exactly what each one costs.
Amazon Fees
Referral Fee
A percentage of your selling price (typically 8-20%) that Amazon charges for marketplace access. Rate depends on product category.
FBA Fulfillment Fee
Covers picking, packing, shipping, and customer service. Based on product size tier and weight. Ranges from ~$3 to $25+.
Monthly Storage
Charged per cubic foot of inventory stored. Off-peak (Jan-Sep) is ~$0.87/cu ft, peak season (Oct-Dec) jumps to ~$2.40/cu ft.
Long-Term Storage
Additional fees for inventory stored over 365 days. Currently $6.90/cu ft or $0.15/unit, whichever is greater. Assessed monthly.
Removal/Disposal
Fees to return inventory to you or dispose of it. Removal is $0.97-$13.05 per unit depending on size. Disposal is $0.32-$2.16.
Size Tiers

Items ≤15" longest side, ≤12" median, ≤0.75" shortest, and ≤1 lb. Lowest fulfillment fee tier at ~$3.22 base.

Large Bulky
Items ≤59" longest side, all dimensions ≤33", and ≤50 lb. Significant jump to ~$9.73 base. Avoid if possible.

How to Calculate Amazon FBA Fees
Knowing your Amazon FBA fees before sourcing a product is the difference between a profitable launch and an expensive lesson. Amazon's fee structure has several components, and each one chips away at your margin. Here's a step-by-step breakdown of every cost you need to account for.
1. Referral Fee
Amazon charges a referral fee on every sale as commission for access to their marketplace. The rate depends on your product category — most categories are 15%, but Electronics is 8% and Jewelry can be as high as 20% for items under $250. For a $30 product in a standard category, expect to pay around $4.50 in referral fees.
2. FBA Fulfillment Fee
This covers picking, packing, shipping, and customer service for your order. The fee is determined by your product's size tier (Small Standard, Large Standard, Large Bulky, or Extra Large) and its shipping weight. A typical 1 lb item in the Small Standard tier costs around $3.22 to fulfill, while a 5 lb Large Standard item runs about $5.75. Keeping your product dimensions compact can save significant money here.
3. Storage Fees
Amazon charges monthly storage fees based on the cubic feet your inventory occupies in their warehouses. Off-peak rates (January through September) are approximately $0.87 per cubic foot. During peak season (October through December), rates jump to $2.40 per cubic foot. Inventory stored over 365 days incurs additional long-term storage fees, so managing turnover is critical.
4. Your Product Cost (COGS)
Your cost of goods sold includes the manufacturing price, shipping from your supplier to Amazon's fulfillment center (typically $0.30-$0.80 per unit by sea freight), import duties, and any inspection or prep fees. If you don't have a supplier quote yet, estimating COGS at 30% of your target selling price is a reasonable starting point.
5. Advertising (PPC) Cost Per Sale
Most sellers need Amazon PPC to drive initial sales and maintain visibility. A common estimate is 15-30% of your selling price per sale in ad spend. For a $25 product, budget $3.75-$7.50 in PPC per unit sold. Competitive categories may require more, especially during launch.
Calculating Your Net Profit
Your net profit is what remains after all costs: Selling Price - Referral Fee - FBA Fee - Storage Fee - COGS - Shipping - PPC = Net Profit. Most successful Amazon sellers target a net margin of 25-35%. Below 15% leaves little room for fee increases or competitive pressure.
