Amazon has updated its monthly FBA storage fee schedule effective April 1, 2026, raising costs across both standard-size and oversized storage categories. Sellers who rely on FBA must review their inventory holding strategies to avoid margin erosion.
What Changed
Standard-size units:
- January–September (non-peak): $0.87 → $0.92 per cubic foot
- October–December (peak): $2.40 → $2.56 per cubic foot
Oversized units:
- January–September: $0.56 → $0.61 per cubic foot
- October–December: $1.40 → $1.50 per cubic foot
Amazon also confirmed that the aged-inventory surcharge (applied to units stored over 271 days) remains unchanged for now, but sellers should expect a review later in 2026.
Why Amazon Made This Change
Amazon cited rising fulfilment centre operating costs, including expanded robotics deployments and increased labour costs at its US warehouse network. The company noted that storage fee rates had not been updated since early 2024 and the adjustment reflects current infrastructure investment.
What This Means for Sellers
Higher storage costs directly compress margins, particularly for sellers carrying slow-moving SKUs or building pre-holiday buffer inventory. For a seller storing 500 cubic feet of standard-size goods through September, the annual cost increases by approximately $300. At peak season, that same inventory now costs an additional $800 per month compared to 2024 rates.
Immediate actions to take:
- Audit your aged inventory — Identify ASINs that have been in FBA warehouses for over 90 days and assess whether removal or liquidation makes more sense than continued storage.
- Revisit reorder quantities — Tighter just-in-time replenishment reduces average cubic footage held, lowering your monthly storage bill.
- Use Amazon's Inventory Dashboard — The IPI score now factors in storage utilisation; keeping it lean improves your score and protects your storage limits.
- Model peak season costs early — If you are planning Q4 stock builds, add the new $2.56/cu ft rate to your unit economics now rather than discovering the impact in November.
Sellers who proactively manage inventory turnover will absorb this change with minimal impact. Those running high-SKU catalogues with slow movers will feel it most acutely.
