How Amazon FBA Fees Work in 2026
Amazon FBA (Fulfillment by Amazon) lets you send inventory to Amazon's warehouses, where they handle storage, picking, packing, shipping, and customer service. In exchange, Amazon charges three main fee types: referral fees, FBA fulfillment fees, and storage fees. Understanding each is critical before sending your first shipment.
The referral fee is Amazon's commission — a percentage of the total sale price that varies by category. Most categories pay 15%, but some like personal computers pay as low as 6% and others like Amazon device accessories pay up to 45%. This fee applies whether you use FBA or fulfill orders yourself (FBM).
The FBA fulfillment fee covers picking, packing, shipping, and handling. It's based on the item's size tier and weight. For a standard-size item weighing under 1 lb, the fulfillment fee is approximately $3.22. Oversize items pay significantly more — a large oversize item can cost $10+ per unit to fulfill.
Finally, monthly storage fees are charged per cubic foot of space your inventory occupies. Standard rates are $0.87 per cubic foot from January to September and $2.40 per cubic foot from October to December (peak season). Inventory that sits for over 365 days incurs additional aged inventory surcharges.
Amazon FBA Fee Breakdown by Size Tier
Amazon categorizes products into size tiers that determine fulfillment fees. Here are the 2026 FBA fulfillment fees for the most common tiers:
| Size Tier | Weight | Fulfillment Fee |
|---|---|---|
| Small Standard | Up to 12 oz | $3.06 - $3.22 |
| Large Standard | Up to 20 lbs | $3.68 - $7.17 |
| Small Oversize | Up to 70 lbs | $9.73+ |
| Medium Oversize | Up to 150 lbs | $19.05+ |
| Large Oversize | Up to 150 lbs | $89.98+ |
Fees increase incrementally by weight within each tier. Products that exceed size or weight limits for a tier are bumped to the next (more expensive) tier.
Is Amazon FBA Worth It? A Profitability Analysis
FBA is worth it when the increased sales volume and higher prices from Prime eligibility outweigh the additional fees. Products that work best with FBA share these characteristics:
- Small and lightweight. FBA fees have the least impact on items under 1 lb. A product that costs $3.22 to fulfill through FBA might cost you $4-5 to ship yourself — making FBA cheaper.
- Priced above $15. Below this price point, Amazon's fees consume too much of the revenue. The referral fee alone on a $10 item is $1.50, plus $3.22 fulfillment — that's nearly half the sale price.
- Fast-turning inventory. Storage fees punish slow sellers. If your product sits in a warehouse for months, those fees accumulate and destroy margins — especially during Q4 peak rates.
Use the calculator above to model your specific product. If your net margin after all Amazon fees is below 20%, consider alternative fulfillment methods or platforms.
Amazon FBA vs. Selling on Other Platforms
Amazon's total effective fee rate (referral + fulfillment + storage) typically ranges from 30-45% of the sale price — significantly higher than eBay's ~14% or Etsy's ~10.5%. However, Amazon drives its own traffic. You're not paying for ads or building an audience — Amazon's 310+ million active customers find your product through search.
For products where Amazon's audience doesn't add value (handmade items, niche collectibles), selling on eBay or Etsy at lower fees often yields better margins. For commodity products where Prime shipping drives conversions, FBA's higher fees can be justified by higher sales volume.
Frequently Asked Questions
What percentage does Amazon FBA take?
Amazon charges a referral fee of 8-15% (15% for most categories) plus FBA fulfillment fees starting at $3.06 per unit for small standard items. Total fees typically range from 30-45% of the sale price when including storage. The exact amount depends on your product's category, size, weight, and how long it sits in the warehouse.
How much does Amazon FBA cost per item?
For a standard-size item under 1 lb sold at $25, expect roughly: $3.75 referral fee (15%), $3.22 fulfillment fee, and minimal storage — about $7 total, leaving you with $18 before your cost of goods. Heavier and larger items cost significantly more. Use the calculator above for precise numbers.
What are Amazon FBA storage fees?
Monthly storage fees are $0.87 per cubic foot from January-September and $2.40 per cubic foot from October-December. Inventory aged over 365 days incurs an additional surcharge. A small product (6x4x2 inches) occupies about 0.03 cubic feet, costing roughly $0.03/month in standard season.
Is Amazon FBA worth it for small sellers?
It can be, if your product is priced above $15, small and lightweight, and turns over quickly. FBA gives you access to Prime customers and Amazon handles all logistics. However, the fees are significantly higher than other platforms. Start with a small test shipment and use this calculator to verify profitability before scaling.
How do Amazon FBA fees compare to eBay?
Amazon FBA fees are roughly 2-3x higher than eBay's. On a $50 item, eBay takes about $6.93 (13.25% + $0.30), while Amazon FBA takes roughly $10.72+ (15% referral + $3.22 fulfillment). However, Amazon handles shipping and customer service, which eBay doesn't. The true comparison depends on your shipping costs and time value.
