The 2025 Guide to FBA Fees: What Every Seller Should Know
If you're selling on Amazon using Fulfillment by Amazon (FBA), understanding the fee structure is critical to maintaining profitability. In 2025, Amazon has introduced several changes to its FBA fees, and whether you're new to the platform or scaling fast, you need to be clear on what you're being charged and why.
In this guide, we'll break down the major FBA fees, help you forecast your costs, and share a few pro tips we use at VirVentures to keep margins healthy across thousands of listings.

Fulfillment
Fees
(per-unit)
Storage

(monthly + aged inventory)

Removal Fees

Processing Fees
1. Fulfillment Fees (2025 Updates)
In 2025, Amazon continues to charge per-unit fulfillment fees based on product size and weight. These fees cover picking, packing, shipping, and customer service.
2025 Updates:
- • There's a greater emphasis on dimensional weight, not just actual weight
- • Peak season surcharges are now standard for Q4 and Prime Day prep windows
| Category | Fee (Standard Size, ≤ 1 lb) | Fee (Oversize, > 3 lb) |
|---|---|---|
| Jan–Sep | $3.22 | $9.25 |
| Oct–Dec (peak) | $3.49 | $9.85 |
Note: Fees vary by size tier (small standard, large standard, small oversize, etc.)
2. Monthly Storage Fees
Amazon charges monthly inventory storage fees based on cubic feet of space occupied.
| Time of Year | Standard Size | Oversize |
|---|---|---|
| Jan–Sep | $0.87/cu. ft. | $0.56 |
| Oct–Dec | $2.40/cu. ft. | $1.40 |
VirTip: Use FBA Inventory Age reports to regularly purge slow-moving SKUs and avoid surprise storage charges.
3. Aged Inventory & Long-Term Storage Fees
For units in FBA longer than 271 days, Amazon now applies Aged Inventory Surcharges — and they get steep quickly.
| Age Bracket | Monthly Surcharge per Unit |
|---|---|
| 271–365 days | $1.50 |
| 365–730 days | $3.00 |
| 730+ days | $6.90 or more |
VirTip: Create automatic removals or reprice slow-moving items aggressively. We use real-time dashboards to flag aging inventory before it becomes a liability.
4. Returns Processing Fees
For categories like apparel and shoes, Amazon charges a Returns Processing Fee when a customer returns a product.
- • Fee = same as fulfillment fee
- • Applies only when Amazon provides free returns
- • This fee isn't widely known, but it can significantly affect profitability for high-return categories
