How Long-Term Storage Fees Work
Amazon charges additional fees for inventory that sits in their fulfilment centres for extended periods. The aged inventory surcharge applies to items stored for more than 181 days, with rates increasing significantly at 271 days and again at 365 days. These fees are charged in addition to standard monthly storage fees and can quickly erode margins on slow-moving products.
Checking Your Inventory Age
Monitor inventory age through the Inventory Health report in Seller Central. This report shows the age distribution of your stock — how many units are in the 0-90 day bucket, 91-180 days, 181-270 days, and 271+ days. Check this report at least monthly. Products approaching the 181-day threshold need immediate attention before surcharges begin accruing.
Prevention: Right-Sizing Your Shipments
The best defence against long-term storage fees is sending the right quantity in the first place. Use sales velocity data to forecast demand. Send enough stock for 60 to 90 days of sales rather than six months. Frequent smaller shipments cost more in inbound shipping but avoid the much higher cost of storage surcharges on excess inventory. This requires discipline and regular replenishment planning.
Price Reduction Strategy
When inventory approaches the 181-day mark, consider reducing your price to accelerate sales. Calculate whether selling at a lower margin beats paying storage surcharges. In many cases, a 20 to 30 percent price reduction moves stock quickly enough to avoid fees entirely. The math is straightforward: compare the projected surcharge cost against the revenue lost from discounting.
Removal Orders Before Fees Hit
If price reductions are not moving stock fast enough, create a removal order before surcharges begin. Having old stock returned to you (or your prep centre) costs the removal fee but saves ongoing surcharges. Once returned, you can sell through alternative channels, relist in smaller quantities, or dispose of genuinely unsellable items. This requires planning ahead of fee dates.
Amazon Outlet and Deals
Outlet deals are specifically designed for aged inventory. Amazon promotes these deals to price-sensitive buyers, helping you move stock that would otherwise incur surcharges. The margins are lower but the alternative — paying surcharges while the product still does not sell — is worse. Use outlet deals proactively for products you can see are not going to sell at full price within the fee-free window.
Building an Inventory Health Routine
Set a recurring monthly review of your inventory health dashboard. Flag products approaching 120 days in storage — this gives you 60 days to take action before surcharges begin. Create a decision matrix: products over 120 days either get price reductions, advertising pushes, or removal orders. Never let stock silently age into surcharge territory through inattention. Proactive management of inventory age is a core skill of profitable Amazon selling.
