Amazon FBA (Fulfillment by Amazon) gives sellers access to Prime customers and Amazon's logistics network — but the fee structure is one of the most complex of any selling platform. This guide breaks down every fee so you know your real profit before you list.
Quick answer: Amazon FBA fees combine a referral fee (15% in most categories, 8% for electronics and computers) with a fulfillment fee (a per-unit fee set by the item's size tier, shipping weight, and — since January 15, 2026 — its price band) plus monthly storage fees.
There are three core fee types every FBA seller pays:
| Category | Referral Fee | On $30 Sale |
|---|---|---|
| Consumer Electronics | 8% | $2.40 |
| Computers | 8% | $2.40 |
| Most categories (incl. Home & Kitchen, Toys & Games) | 15% | $4.50 |
| Clothing & Accessories | 17% above $20 (10% for $15.01–$20, 5% up to $15) | $5.10 |
| Jewelry | 20% on first $250, 5% above | $6.00 |
A minimum referral fee of $0.30 applies in most categories if the percentage-based fee falls below that amount. Amazon's US referral fees haven't changed for 2026.
Since January 15, 2026, Amazon's fulfillment fee depends on three things: the item's size tier (small standard, large standard, and larger bulky tiers), its shipping weight (the greater of actual and dimensional weight), and its price band — items priced under $10 pay lower fulfillment fees than the same item priced higher. On top of that, Amazon added a 3.5% fuel and logistics surcharge to FBA fulfillment fees from April 17, 2026.
Because the rate card now has so many combinations, the reliable way to get your exact figure is Amazon's own Revenue Calculator in Seller Central: enter your product and it shows the current fulfillment fee. Small, light items still pay the least, and crossing a size or weight boundary — even by a fraction of an inch or ounce — can raise the fee noticeably.
FBA storage is billed monthly per cubic foot of space your inventory occupies. The rate is substantially higher from October to December, when warehouse space is in peak demand, and inventory that sits unsold for too long incurs aged-inventory surcharges on top of regular storage. Amazon's storage fee page lists the current rates for each size tier.
⚠️ Slow-moving stock: Storage fees keep accruing every month an item sits in Amazon's warehouse, and aged-inventory surcharges make old stock progressively more expensive. Send inventory in quantities you expect to sell within a few months.
Use this formula to find your true profit per unit:
Profit = Sale Price − Referral Fee − FBA Fee − Storage Fee − Product Cost − Shipping to Amazon
Example: A $30 item in Electronics (8% referral) with a $4.50 FBA fee (from Amazon's Revenue Calculator) and $0.15 storage per unit: $30 − $2.40 (referral) − $4.50 (FBA) − $0.15 (storage) − $8 (product cost) = $14.95 profit (50% margin)
| Platform | Fee on $100 Sale | You Keep |
|---|---|---|
| Shopify Basic (own store, plus $39/month plan) | $3.20 | $96.80 |
| Etsy | $9.95 | $90.05 |
| eBay (most categories) | $14.00 | $86.00 |
| Amazon, electronics (referral only) | $8.00 + FBA fee | $92.00 − FBA fee |
| Amazon, most categories (referral only) | $15.00 + FBA fee | $85.00 − FBA fee |
Once the FBA fulfillment fee is added, Amazon usually costs more than other marketplaces, but Prime eligibility often drives significantly higher conversion rates — for many sellers, the trade-off is worth it.
