Q: How much are Amazon FBA fulfillment fees in 2026?

FBA Pick & Pack fees start at approximately $3.22 for Small Standard items (under 4 oz) and scale to $3.80–$5.50+ for Large Standard items (under 1–3 lbs). Oversize items start around $9.73+. In Q4 (Oct 15 – Jan 14), Amazon slaps an extra seasonal peak surcharge of $0.20 to $0.95+ per unit.

Q: What is the Amazon Inbound Placement Service fee?

Introduced in 2024, Amazon charges ~$0.21 to $0.34+ per unit if you send inventory to a single receiving center (Minimal Split) so Amazon can distribute it across the country. If you split your shipment across 4+ warehouses yourself, the fee drops to $0.

Q: What is the Low-Inventory-Level fee?

If your inventory drops below 28 days of historical supply relative to sales, Amazon charges a penalty fee per unit sold (typically $0.30 to $1.11). Keeping consistent restock schedules eliminates this fee completely.

Q: Can I audit my entire Amazon catalog with a CSV?

Yes! Use FeeSpotter's 'Catalog Audit' tab to upload your active Amazon inventory report. It instantly flags unprofitable ASINs and cash-bleeding products across your catalog.

Q: What is Break-Even ACoS % and how do I set my Amazon PPC target?

Break-Even ACoS (Advertising Cost of Sales) is your net profit margin before ad spend: (Net Margin Before Ads ÷ Selling Price) × 100. If your margin before ads is 32%, your Break-Even ACoS is exactly 32%. If your Sponsored Products campaign ACoS is 38%, you are paying Amazon more in ad spend than you earn in gross profit.

Q: How do customer returns affect Amazon FBA fees?

When an Amazon customer returns an item, Amazon refunds the category referral fee minus a 20% Refund Administration Fee (capped at $5.00). However, Amazon retains the original FBA Pick & Pack fee, and on apparel/shoes categories, charges a Returns Processing Fee ($1.85+). If the item is marked customer damaged, you also absorb the lost COGS.

Q: When is FBM (Merchant Fulfilled) more profitable than FBA?

FBM is typically more profitable for heavy or oversized products (where FBA fees jump to $10–$25+ per unit), slow-moving SKUs with high storage duration, or during Q4 holiday storage surges (Oct–Dec) when Amazon nearly quadruples monthly warehouse storage rates from $0.87 to $2.40 per cubic foot.
