Amazon Low Inventory Level Fee 2026: The Other Side of the Storage Trade-Off
The inventory Goldilocks problem
Run too much inventory: storage utilization surcharge + aged inventory fees. Run too little: low inventory level fee. Amazon has created financial pressure on both sides of the target range.

When your FBA inventory drops below Amazon's recommended level for a standard-size ASIN, Amazon has to ship orders to customers from farther fulfillment centers because the nearest ones don't have your product. Amazon charges you the incremental shipping cost — framed as a fee — for each unit shipped during that low-inventory window. The fee was introduced in April 2024 and has been active since.
2026 fee rates
Applies to standard-size only. Large bulky and extra-large are currently exempt.
| Severity tier | Fee per unit | Notes |
|---|---|---|
| Standard-size, low severity | $0.32/unit | Inventory low but within 1 reorder cycle |
| Standard-size, medium severity | $0.72/unit | Inventory critically low |
| Standard-size, high severity | $1.11/unit | Near stockout conditions |
The inventory sweet spot
Amazon has effectively created a target inventory band by penalizing both extremes. The rough target based on both fee thresholds:
How to avoid the low inventory fee
- Use Amazon's Restock recommendations. The Inventory Planning dashboard shows recommended restock quantities and dates based on your current velocity and projected days of supply. Trust the math on these for established ASINs with 6+ months of sales history.
- Shorten your reorder lead time. The most common cause of low inventory isn't ignoring it — it's being surprised by a velocity spike or manufacturing delay. Shorter lead times mean faster recovery when inventory dips.
- Build a 14-day safety buffer into your reorder point. If your lead time is 30 days, set your reorder point at 44 days of supply (30-day lead + 14-day buffer). The fee kicks in when you're below Amazon's recommendation, which is typically 2× your lead time.
- Check for receiving delays before assuming you're understocked. If Amazon is slow to receive a shipment, your "available" inventory drops even though units are in the building. Seller Central shows incoming shipments — if a lot of inventory is "in transit to Amazon," account for it before you panic-reorder.
Frequently asked questions
What is Amazon's low inventory level fee? ▾
A fee introduced in April 2024 charged when your FBA inventory for a standard-size ASIN consistently falls below Amazon's recommended level based on your historical sales velocity. When you run lean, Amazon has fewer units to distribute to nearby fulfillment centers, forcing it to ship from farther away — Amazon charges you for that extra shipping cost.
How much is the low inventory level fee? ▾
The fee ranges from $0.32 to $1.11 per unit for standard-size items, based on how severely understocked you are relative to Amazon's recommended level. The fee is assessed on units that are shipped while you're in low-inventory status — not on all units in the period.
How does Amazon calculate whether I'm understocked? ▾
Amazon compares your 'historical days of supply' (how many days your inventory would last based on recent sales velocity) to your 'long-term average days of supply.' If your current supply covers significantly fewer days than your historical average, you're flagged as low inventory. The threshold varies by product and is based on Amazon's internal network optimization.
Am I exempt from the low inventory level fee? ▾
Yes, if you have a 'healthy' supply chain as measured by your IPI score, or if your product is in the FBA New Selection program (first 365 days for new-to-FBA sellers, first 180 days for existing sellers with new ASINs). Also exempt: products where Amazon determines your low inventory is due to their own receiving delays (Seller Central will show a flag).
How do I check if I'm being charged the low inventory fee? ▾
In Seller Central: Inventory > FBA Inventory > scroll to 'Low-inventory-level fee' column. You can also find charges in Reports > Payments > Transaction View and filter for 'FBALowInventoryLevelFee.' The Inventory Health report shows current risk level by ASIN.
How does the low inventory fee interact with the storage utilization surcharge? ▾
They're opposite incentives. The storage utilization surcharge penalizes overstocking (above 26 weeks of cover). The low inventory fee penalizes understocking. The 'target zone' Amazon wants you in is roughly 4–26 weeks of cover — enough to fill network needs without being so much that you're warehousing. This is the tension every FBA brand has to manage.
