What Are Amazon FBA Fees in 2026?

Amazon FBA (Fulfillment by Amazon) fees are the costs sellers pay to have Amazon store, pack, ship, and handle customer service for their products. In 2026, there are four main fee components that every FBA seller needs to understand to price their products profitably.

Net Profit = Sale Price − Referral Fee − Fulfillment Fee − Fuel Surcharge − Storage − COGS − Shipping − Ad Spend

On average, Amazon FBA fees consume 25%–35% of your gross sale price. Electronics categories tend to be lower (22%–28%) while clothing and accessories can reach 35%–40% due to higher referral fees and return rates.

Amazon FBA Referral Fees by Category (2026)

The referral fee is Amazon's commission on every sale. It ranges from 6% to 45% depending on your product category. The rate has been unchanged since 2025.

CategoryReferral FeeNotes
Electronics & Computers8%Lowest standard tier
Personal Care (under $10)8%Price-dependent tier
Books, Music, Video Games15%+ $1.80 closing fee on media
Home & Kitchen15%Most common rate

Clothing (over $20)17%Tiered by price
Jewelry (up to $250)20%Drops to 5% above $250
Amazon Device Accessories45%Highest referral rate

A $0.30 minimum referral fee applies when the percentage-based calculation falls below that floor. This mainly impacts very low-priced items.

FBA Fulfillment Fees by Size Tier (2026)

Fulfillment fees cover Amazon's pick, pack, ship, and customer service. Fees are based on your product's size tier and shipping weight (the greater of actual weight or dimensional weight).

The 2026 Fuel and Logistics Surcharge

Effective April 17, 2026, Amazon applies a 3.5% fuel and logistics surcharge on all FBA fulfillment fees in the US and Canada. This surcharge is calculated on the fulfillment fee only, not on your selling price, referral fee, or storage.

On a typical standard-size product, this adds approximately $0.17 per unit. While that sounds small, across 5,000 units it equals $850 in additional annual costs. Our calculator includes this surcharge by default.

Monthly Storage Fees (2026)

Amazon charges monthly storage fees based on the volume your inventory occupies. The rate roughly triples during Q4 (October–December) due to peak holiday demand.

PeriodStandard SizeOversize
January – September$0.87/cu ft$0.56/cu ft
October – December (Peak)$2.40/cu ft$1.40/cu ft

Aged inventory surcharges begin after 181 days at $0.50/cu ft, increasing steeply after 271 days. Inventory stored 366+ days may be charged $7.90/cu ft or $0.35/unit, whichever is greater.

How to Reduce Your Amazon FBA Fees

  • Optimize packaging dimensions — even 0.5 inches can drop your product into a cheaper size tier. Packaging is your single biggest lever.
  • Ship to 5+ fulfillment centers — this avoids inbound placement fees of $0.21–$1.58 per unit.
  • Maintain 28+ days of inventory supply — avoids the low-inventory-level fee entirely.
  • Liquidate slow-moving inventory before 181 days — avoids aged inventory surcharges that scale aggressively.
  • Enroll in SIPP (Sustainability in Packaging Program) — qualifies for discounted fulfillment rates.
  • Use professional prep services — avoids $0.32–$5.72 per-unit defect fees.

Example: FBA Fee Breakdown for a $29.99 Product

Here is a worked example for a typical Home & Kitchen product selling at $29.99 with $8.00 COGS:

Monthly Storage−$0.15~0.17 cu ft at $0.87/cu ft
Product Cost (COGS)−$8.00Your landed cost
Net Profit$11.8539.5% margin

This product clears Amazon's total fee take of $10.14 (33.8% of price) and delivers a healthy 39.5% net margin. Products in this range are strong FBA candidates.

Frequently Asked Questions

FBA cost per unit ranges from $3 to $12+ depending on product size, weight, and category, before accounting for storage and the 2026 fuel surcharge. The total per-unit cost stacks fulfillment plus referral plus storage. Use our calculator above for exact numbers based on your specific product.
The main fee types are referral fees (8%–17% per sale), FBA fulfillment fees ($3–$12+ per unit), monthly storage fees ($0.56–$2.40/cu ft), and the 2026 fuel surcharge (3.5% on fulfillment). Additional fees include aged inventory surcharges, inbound placement fees, returns processing, and removal fees.
Most successful Amazon sellers target 20%–35% net profit margin after all fees and costs. A minimum of 25% net margin is recommended to sustain advertising spend and absorb unexpected costs like returns, chargebacks, and seasonal fee increases. Below 15% margin, FBA becomes very difficult to sustain profitably.
Amazon added a 3.5% fuel and logistics surcharge applied to FBA fulfillment fees, effective April 17, 2026. It averages about $0.17 per unit for standard-size items. The surcharge applies only to fulfillment fees — not referral fees, storage, or other charges. There is no announced end date for this surcharge.
Subtract COGS, referral fee (8%–17%), fulfillment fee ($3–$12+), fuel surcharge (3.5% of fulfillment fee), and monthly storage from retail price to get net margin per unit. Target a minimum 25% net margin to sustain advertising. Use our FBA calculator above for exact numbers with 2026 rates.
Our calculator uses off-peak storage rates ($0.87/cu ft) by default. During Q4 (October–December), storage rates triple to $2.40/cu ft. Additionally, a Q4 peak fulfillment surcharge applies from October 15 through January 14, adding an extra per-unit fee on top of standard fulfillment rates. Factor these into your Q4 profitability projections.

Yes, for products with 20%+ net margins after all fees. FBA provides Prime eligibility which drives 25%–40% higher conversion rates, handles customer service and returns, and reaches 90% of the US population with two-day delivery.

Amazon typically takes 25%–35% of your gross sale price when combining all FBA fees. For a $50 product in most categories: referral fee 15% ($7.50), fulfillment (~$5.50), fuel surcharge (~$0.19), and storage (~$0.65) equals approximately $13.84 total (27.7%). Electronics categories are lower while clothing can reach 35%–40%.
Keep more than 28 days of supply in Amazon's fulfillment network and the low-inventory-level fee never applies. This fee was introduced to encourage healthy inventory levels. Calculate your days of supply as: (Current Inventory) ÷ (Average Daily Units Sold). Maintain at least 30 days of supply as a safety buffer to avoid any risk of this fee.
