Amazon FBA long term storage fees are monthly aged inventory surcharges applied to units stored in fulfillment centers for more than 180 days. Sellers can avoid these extra costs by actively monitoring their inventory age reports and removing or discounting products before they reach the 180-day threshold. Managing these charges requires a consistent review of your Seller Central dashboard and a clear understanding of your stock turnover rates to ensure profitability remains high throughout the year.
What are Amazon FBA long term storage fees?
Amazon maintains a specific policy regarding how long products can stay in their fulfillment network. When inventory sits in a warehouse for an extended period, it consumes space that could be used for faster-moving items. Consequently, Amazon assesses aged inventory surcharges monthly on items stored in fulfillment centers for longer than 180 days. These fees are separate from your standard monthly inventory storage fees, which are based on the average daily volume of space your inventory occupies.
A typical account often overlooks these fees until a monthly statement arrives with unexpected charges. The fee structure is designed to encourage sellers to keep their inventory lean and fresh. If you have products that have been sitting for six months, you are likely triggering these surcharges. Understanding the difference between standard storage and long-term storage is the first step toward better cash flow management for your business.
How can you identify aged inventory in Seller Central?
Identifying which products are approaching the 180-day mark is straightforward if you know where to look. Navigate to the Inventory tab in your Seller Central account and select Inventory Planning. From there, the Inventory Age report is your primary tool for tracking how long each SKU has been stored at a fulfillment center. This report provides a breakdown of your stock based on age brackets, making it easy to see which items are at risk of incurring additional costs.
In a typical account, sellers filter this report by age to identify items that are nearing the 180-day cutoff. You can also view the estimated surcharge for each product if you choose not to take action. Exporting this data to a spreadsheet allows you to calculate the potential impact on your margins. By setting a recurring calendar reminder to check this report every two weeks, you prevent stock from sitting idle for too long without your knowledge.
How Alien Road applies inventory management
At Alien Road, we use a systematic approach to help clients manage their FBA storage footprint. Our process begins with a full audit of the current inventory age reports within the client’s Seller Central account. We establish a threshold for each product category based on historical sales velocity and seasonal demand. By aligning replenishment orders with actual consumption rates, we reduce the likelihood of stock piling up in fulfillment centers.
For example, in a typical engagement, we review inventory performance every month to identify slow-moving SKUs. If a product shows signs of stagnation, we recommend a promotional strategy or a removal order before the next assessment date. We also track the impact of these changes on total storage costs to demonstrate the financial benefit of a lean inventory model. This proactive management keeps our clients’ storage expenses predictable and helps protect their net profit margins.
What strategies reduce long term storage costs?
Reducing storage fees requires a mix of inventory control and aggressive sales tactics. If you have excess stock that is not moving, you must act before it triggers an aged inventory surcharge. Here are several practical steps you can take to clear out older units effectively:
- Create a removal order to send stagnant inventory back to your warehouse or a disposal facility.
- Run an Amazon Outlet promotion to discount slow-moving items and increase their sell-through rate.
- Adjust your replenishment settings to reflect current sales trends rather than past projections.
- Bundle slow-moving items with high-velocity products to encourage faster inventory turnover.
- Use Sponsored Products ads to boost visibility for items that have been in stock for over 90 days.

| Flash Sale | Increase velocity | Medium |
| Price Cuts | Liquidate stock | High |
Why does inventory age matter for your profit margins?
Profitability in the FBA model is often eroded by hidden costs like storage. When you pay for storage on units that do not sell, you are essentially paying for the privilege of losing money on those items. As products stay longer in a warehouse, the cumulative cost of storage can eventually exceed the profit margin you expected to make from the initial sale. This is why keeping a close eye on your inventory age is just as important as managing your advertising spend.
A common pattern is that sellers focus heavily on PPC and conversion rates but ignore storage efficiency. You should compare your storage costs against your gross profit per unit to see if your stock levels are sustainable. If a product is not profitable after accounting for long-term storage fees, it may be time to discontinue that SKU or change your sourcing strategy. Maintaining a high inventory turnover rate is the most effective way to ensure that your capital is always working for you rather than sitting in a warehouse.
How to plan your inventory replenishment cycles
Effective replenishment is about balancing stock availability with the cost of storage. You should use the sales data available in the Business Reports section to calculate your average daily sales velocity. Once you know how many units you sell per month, you can determine an optimal stock level that covers your lead time plus a small safety buffer. Avoid the temptation to over-order during peak seasons unless you have verified historical data that supports the volume.
Setting up reorder alerts is a great way to stay organized. Many sellers choose to order in smaller batches more frequently rather than placing one massive order that sits for months. This approach carries a higher logistics cost but often results in lower overall storage fees and better cash flow. Consistency is the key to preventing inventory pile-ups that lead to unwanted surcharges.

Frequently Asked Questions
How often does Amazon check for aged inventory?
Amazon assesses aged inventory surcharges on a monthly basis. This means you have a recurring window every month to audit your stock levels and take corrective action. If you clear out items before the assessment date each month, you can successfully avoid these surcharges entirely.
Does the removal order process take a long time?
Removal orders typically take several weeks to process depending on the volume of inventory and the time of year. Because it is not an instant process, you should initiate your removal requests well before the 180-day threshold is reached to ensure the stock is cleared in time.
Are there specific categories exempt from these fees?
Amazon policies regarding storage fees apply broadly to most standard-size and oversized items. There are generally no broad category exemptions from aged inventory surcharges. It is best to assume all your stored inventory is subject to these assessments and plan your inventory levels accordingly to maintain profitability.
Can I see the impact of these fees in my reports?
Yes, you can track these costs in the Payments report or the Inventory Ledger. These reports provide a detailed breakdown of all fees charged to your account, including long-term storage and aged inventory surcharges. Reviewing these regularly helps you understand the true cost of your storage decisions.
