If you’ve been selling on Amazon FBA for any length of time, you’ve likely felt the sting of long-term storage fees. What starts as a manageable monthly cost can quickly escalate into a serious drain on your profitability—especially when slow-moving or seasonal inventory begins piling up in Amazon’s fulfillment centers.
The good news? There are proven strategies to avoid these fees entirely—and liquidating excess FBA inventory is one of the most effective. In this comprehensive guide, we’ll walk you through everything you need to know about Amazon’s long-term storage fee structure, when and how to take action, and how bulk liquidation can help you recover capital while eliminating costly fee burdens.
What Are Amazon Long-Term Storage Fees?
Amazon charges sellers for inventory stored in its fulfillment centers on a monthly basis. Beyond standard monthly storage fees, Amazon imposes long-term storage fees (LTSF) on inventory that has been sitting in fulfillment centers for extended periods.
Current LTSF Structure:
As of the most recent Amazon fee updates:
- Inventory aged 181–270 days: $1.50 per cubic foot per month
- Inventory aged 271–365 days: $6.90 per cubic foot per month
- Inventory aged 365+ days: $6.90 per cubic foot per month (or $0.15 per unit, whichever is greater)
These fees are assessed on the 15th of each month for all affected inventory. For sellers with large quantities of slow-moving products, these fees can add up to hundreds or even thousands of dollars monthly.
Amazon assesses storage utilization through its Inventory Performance Index (IPI) score—a metric that measures how efficiently you manage FBA inventory. A low IPI score (below 400) can result in storage limits that restrict your ability to send new inventory to Amazon’s warehouses. For current fee details, always check Amazon’s official Seller Central help pages.
Why Does Excess FBA Inventory Accumulate?
Understanding why excess inventory builds up is the first step in preventing it. Common causes include:
1. Inaccurate Demand Forecasting
Ordering too much inventory based on overly optimistic sales projections is perhaps the most common cause. Market conditions change, competitors launch similar products, and consumer trends shift unexpectedly.
2. Failed Product Launches
Not every product resonates with customers. When a new ASIN underperforms, sellers are left with large quantities of inventory that isn’t moving—and the storage fees keep accumulating regardless.
3. Seasonal Demand Mismatches
Seasonal products carry inherent risk. Holiday merchandise, summer products, or back-to-school items can leave sellers with significant excess inventory when the selling window closes.
4. Algorithm and Ranking Changes
Amazon’s A9 algorithm can dramatically affect product visibility. A ranking drop can turn a fast-moving product into a slow seller overnight, quickly leading to excess inventory situations.
5. Supplier Minimum Order Quantities
Many suppliers require minimum order quantities that exceed your actual sales velocity, especially for newer products still establishing their market presence.
6. Stranded Inventory
Listing errors, policy violations, or account issues can cause inventory to become stranded—sitting in Amazon’s warehouses but not available for purchase. Stranded inventory still incurs storage fees while generating zero revenue.
Recognizing the Warning Signs Early
The key to avoiding significant LTSF is early detection. Monitor these metrics regularly in your Seller Central dashboard:
Inventory Age Report
Amazon’s Inventory Age report shows how long each ASIN has been in fulfillment centers. Review this weekly and take immediate action on inventory approaching the 180-day mark.
Sell-Through Rate
This metric measures how quickly your inventory sells relative to how much you’ve sent in. A sell-through rate below 2.0 is a warning sign that inventory may be heading toward long-term storage territory.
Restock Recommendations
Amazon’s restock recommendations work both ways—they also indicate when you have excess inventory relative to current sales velocity.
FBA Inventory Health Dashboard
Amazon’s Inventory Health report provides a comprehensive view of your stock levels, sales velocity, and recommended actions. Make this a regular part of your weekly seller routine.
Strategies to Prevent Long-Term Storage Fees
Before inventory reaches the 180-day threshold, you have several options to move it:
1. Aggressive Repricing
Lowering your price is the fastest way to increase sales velocity. Use dynamic repricing tools to stay competitive and move inventory before storage fees escalate. Even selling at or slightly below cost is often preferable to accumulating months of LTSF.
2. Amazon Advertising (PPC)
Investing in Sponsored Products campaigns can boost visibility for slow-moving ASINs. Calculate whether the cost of advertising plus reduced margins is still better than ongoing storage fees.
3. Amazon Deals and Coupons
Lightning Deals, 7-Day Deals, and digital coupons can drive significant traffic to slow-moving products. These promotional tools are particularly effective for clearing inventory before fee assessment dates.
4. Amazon Outlet
Amazon Outlet is a dedicated section for overstock and clearance products. Enrolling eligible products in Amazon Outlet can drive additional sales without significant advertising investment.
5. Multi-Channel Fulfillment (MCF)
Use your FBA inventory to fulfill orders from other sales channels—your own website, eBay, Walmart Marketplace, or other platforms. This draws down FBA inventory without requiring removal.
6. Create Bundles or Variation Listings
Combining slow-moving products with faster-selling items in bundles can increase overall sales velocity. New product bundles can also refresh interest in otherwise stagnant inventory.
When Liquidation Becomes the Right Choice
Despite your best efforts, sometimes inventory simply won’t move through normal sales channels quickly enough to avoid significant LTSF. This is when liquidation becomes not just an option but the financially sound choice.
Signs That Liquidation Is Your Best Option:
- Inventory is approaching or has passed the 180-day mark with no improvement in velocity
- Price reductions and advertising haven’t meaningfully increased sales
- The cost of continued storage plus advertising exceeds potential profit margins
- You need capital freed up quickly to reinvest in better-performing products
- Amazon’s next LTSF assessment date is approaching rapidly
- Your IPI score is suffering due to excess inventory levels
Amazon’s Built-In Liquidation Program
Amazon offers its own liquidation program where they sell your excess inventory to wholesale buyers at a recovery rate typically between 5-10% of the average selling price. While convenient, the recovery rates are often significantly lower than what you can achieve through third-party buyers.
For a detailed comparison of Amazon’s program versus third-party liquidation options, consider researching both paths thoroughly before making a decision.
How Bulk Liquidation Works for FBA Sellers
Working with a specialized FBA inventory buyer like FBA Inventory Sellers offers distinct advantages over Amazon’s built-in program:
Step 1: Prepare Your Inventory List
Export your inventory data from Seller Central, including:
- ASIN and product descriptions
- Quantity available in FBA
- Current selling price and sales velocity
- Inventory age and estimated storage fees
- Product condition and any known issues
The more detail you provide, the faster and more accurate the quote process will be. Download a blank inventory template to help organize your data efficiently.
Step 2: Submit for Evaluation
Submit your inventory list to a bulk FBA inventory buyer. Experienced buyers like FBA Inventory Sellers can typically provide a quote within 24-48 hours based on current market conditions, product categories, and inventory age.
Step 3: Receive and Evaluate Your Offer
A reputable buyer will provide a transparent, no-obligation offer. Compare this against:
- Projected future LTSF costs if inventory remains in Amazon
- Estimated revenue from continued sales attempts minus advertising costs
- Recovery rate versus Amazon’s built-in liquidation program
In most cases, bulk liquidation to a specialized buyer yields significantly better recovery rates than Amazon’s own program.
Step 4: Initiate Amazon Removal Order
Once you’ve agreed on terms, you’ll create a removal order in Seller Central directing Amazon to ship your inventory to the buyer’s warehouse. The buyer handles all coordination and logistics from this point forward.
Step 5: Get Paid
After inventory verification, you receive payment according to the agreed terms. The entire process from submission to payment typically takes one to two weeks—far faster than waiting for organic sales that may never materialize.
Calculating Your Break-Even Point
Before deciding between continued sales attempts and liquidation, calculate your break-even point:
Monthly LTSF + Monthly Standard Storage + Advertising Costs + Time Value of Tied-Up Capital = True Cost of Holding Inventory
Compare this against your projected liquidation recovery. If the monthly holding cost exceeds 5-8% of inventory value, liquidation is almost certainly the more profitable choice.
Example Calculation:
- Inventory value (at cost): $10,000
- Monthly storage fees: $450
- Monthly advertising spend: $300
- Projected LTSF (next assessment): $800
- Total monthly holding cost: $1,550 (15.5% of inventory value)
In this scenario, liquidating at even 20-25 cents on the dollar of retail value would be significantly more profitable than continuing to hold the inventory.
Proactive Inventory Management: Preventing Future Problems
Once you’ve resolved your immediate excess inventory situation, implement these practices to prevent future LTSF issues:
Set Up LTSF Alerts
Monitor your Inventory Age report weekly and set calendar reminders 60 days before inventory hits the 180-day mark. This gives you adequate time to take corrective action.
Establish a 90-Day Review Cycle
Every 90 days, review all FBA inventory against current sales velocity. Any product with less than 60 days of supply should be evaluated for restock; any product with more than 120 days of supply should be evaluated for action.
Build Liquidation Into Your Business Model
Rather than treating excess inventory as a crisis, build liquidation into your standard operating procedures. Establish relationships with bulk buyers before you need them, so when excess inventory situations arise, you can act immediately rather than scrambling for solutions.
Consider Third-Party Logistics (3PL) for Overflow
For inventory you’re not ready to sell immediately, consider storing it at a 3PL facility rather than sending it directly to Amazon. This gives you more control over timing and eliminates LTSF risk while you build sales momentum.
The Bottom Line
Amazon’s long-term storage fees are a significant and growing cost for FBA sellers. The most effective way to avoid them is through proactive inventory management—monitoring your inventory age, acting early on slow-moving products, and having a clear liquidation strategy ready when needed.
When organic sales and promotional strategies aren’t moving inventory fast enough, working with a specialized FBA inventory buyer provides the fastest path to capital recovery while eliminating ongoing storage fee burdens. The key is acting before fees compound to the point where they significantly erode your margins.
