Amazon Fee Changes 2026: Every Fee Update Explained
TL;DR

Amazon updated FBA fees, referral fees, and storage fees for 2026. Most sellers see less than 1% margin impact, but oversized items and slow-moving inventory got hit harder. Key changes: updated aged inventory surcharges, low-inventory-level fee adjustments, and size tier reclassifications. Check for wrong size tier classifications — they're costing many sellers money they don't realize.

2026 fee changes overview

Amazon updates its fee structure annually. For 2026, changes span referral fees, FBA fulfillment fees, monthly storage fees, and several surcharges. The overall theme: Amazon is encouraging faster inventory turnover and penalizing aged or understocked inventory.

For most sellers with standard-size products and healthy inventory velocity (under 90 days average age), the net impact is minimal — less than 1% on margins. The biggest hits are on oversized items, slow-moving inventory, and products near size-tier boundaries.

For the complete breakdown of Amazon's fee structure, see our FBA fees explained guide.

Referral fee updates

Referral fees (Amazon's percentage commission on each sale) remained mostly unchanged for 2026. Key category rates:

  • Most categories: 15% (unchanged)
  • Electronics: 8% (unchanged)
  • Personal computers: 6% (unchanged)
  • Media (books, music, video): 15% (unchanged)
  • Amazon device accessories: 45% (unchanged)
  • Grocery: 8% for items under $15, 15% above (adjusted threshold)

The grocery threshold adjustment is the most notable change — products priced just above $15 now pay significantly more in referral fees. If you sell grocery items near this price point, consider your pricing strategy carefully.

FBA fulfillment fee changes

Standard-size items: Most rates decreased slightly ($0.02-0.10 per unit). Amazon is incentivizing more sellers to use FBA for standard-size products.

Oversized items: Rates increased for the largest tiers ($0.30-0.75 per unit increase). Amazon is discouraging very large products from FBA or pricing the true cost of handling them.

Size tier boundaries: Amazon adjusted some size tier cutoffs. Products near boundaries should be re-measured. Being classified in a higher tier than necessary costs $0.50-2.00 per unit in excess fees.

The lesson: if your product is near a size tier boundary (e.g., just over 15" or just over 20 lbs), investigate whether slight packaging changes could drop you into a lower tier. Even a 0.1" reduction in packaging can save tens of thousands annually on a high-volume product.

Storage and aged inventory fees

Monthly storage rates:

  • January-September: $0.87/cubic foot (standard size), $0.56/cubic foot (oversized)
  • October-December: $2.40/cubic foot (standard), $1.40/cubic foot (oversized)

Aged inventory surcharges (increased for 2026):

  • 181-210 days: $1.50/cubic foot
  • 211-240 days: $3.80/cubic foot
  • 241-270 days: $5.45/cubic foot
  • 271-300 days: $7.60/cubic foot
  • 301-330 days: $11.25/cubic foot
  • 331-365 days: $15.00/cubic foot
  • 365+ days: $6.90/unit or $0.15/unit (whichever is greater)

The surcharges increase steeply — inventory sitting 9+ months in FBA is extremely expensive. Monitor your long-term storage dashboard and remove slow movers before the 181-day threshold.

New fees to watch

Low-inventory-level fee: Applies when you maintain less than 28 days of supply. Ranges from $0.32-0.97 per unit depending on size tier. This penalizes sellers who keep FBA inventory dangerously low.

The intent: Amazon wants enough inventory in their warehouses to fulfill Prime delivery promises. If your stock runs too low, Amazon can't guarantee fast shipping, which hurts customer experience.

The solution: maintain 4-8 weeks of supply at FBA. Use automated inventory monitoring to ensure you reorder before hitting the 28-day threshold.

How it affects your margins

For a typical seller with standard-size products, healthy turnover, and proper size tier classification:

  • Small standard products ($15-25): Net impact: −$0.02 to +$0.05 per unit. Negligible.
  • Large standard products ($25-50): Net impact: −$0.10 to +$0.03 per unit. Minimal.
  • Oversized products ($30-100): Net impact: −$0.30 to −$0.75 per unit. Noticeable for high-volume products.
  • Products with aged inventory: Potential impact: −$1.50 to −$15.00 per cubic foot per month. Significant if you have slow movers.

How do I avoid aged inventory surcharges?
Monitor your inventory age dashboard in Seller Central. Create removal orders or run promotions for inventory approaching 181 days. Set up automated alerts at 150 days to take action before surcharges hit.
