Every year, Amazon updates its fee structure. And every year, the conversation among sellers is the same — how do we protect our margins when the cost of selling on Amazon keeps climbing?
In 2026, that conversation is more urgent than ever. Between fulfillment fee increases, tightened aged inventory surcharges, storage utilization penalties, and new inbound fees, the cost of holding excess FBA inventory has never been higher. For many sellers, the math on slow-moving stock has fundamentally changed — and liquidating sooner rather than later is the financially smarter move.
Here’s a full breakdown of what’s changed and how to decide when it’s time to sell.
What Amazon’s 2026 Fee Changes Actually Mean for Your Inventory
Fulfillment Fee Increases
In 2026, fulfillment fees rose slightly — by about $0.12 to $0.51 per unit depending on size and price tier — while Amazon phased out some internal prep services.

In 2026, FBA fees will increase by an average of $0.08 per unit sold, representing less than 0.5% of an average item’s selling price.

Aged Inventory Surcharges Are Now More Aggressive
This is where slow-moving excess FBA inventory really starts to hurt. Amazon’s aged inventory surcharges now kick in at 181 days — and they increase the longer your items sit unsold. Brandwoven
For inventory aged over 15 months, Amazon introduced a new surcharge tier of $0.35 per unit or $7.90 per cubic foot.

Storage Fees Peak Sharply in Q4
Off-peak storage runs $0.87 per cubic foot, but during Q4 peak season this spikes to $2.40 per cubic foot — and aged inventory surcharges on top of that can push the effective rate even higher for slow-moving stock. TBA Global
If you’re heading into Q4 with excess FBA inventory that isn’t turning, you’re about to get hit with the most expensive storage period of the year on products that aren’t generating revenue.
The IPI Fee Multiplier Effect
Beyond direct storage fees, excess FBA inventory drags down your Inventory Performance Index score — which in turn restricts how much new inventory you can send in. A strong IPI score and good sell-through rate are your best defense against storage limits. Regularly removing or marking down slow sellers keeps your catalog optimized. Tonlexing Logistics
In other words, the cost of holding excess FBA inventory isn’t just the storage fee line item. It’s also the lost revenue from being unable to restock your best sellers because your capacity is being consumed by slow movers.
The Real Cost of Holding Excess FBA Inventory in 2026
Let’s make this concrete. Consider a seller holding 500 units of slow-moving excess FBA inventory with a cubic footprint of 200 cubic feet:
- Monthly storage (off-peak): $0.87 × 200 = $174/month
- Monthly storage (Q4 peak): $2.40 × 200 = $480/month
- Aged inventory surcharge (181–270 days): additional per-unit charges accumulating monthly
- IPI drag: reduced capacity blocking restock of profitable SKUs
- Opportunity cost: capital tied up in unsold units unavailable for reinvestment
Over six months, that 200 cubic feet of excess FBA inventory could easily cost $1,500–$2,500+ in direct fees alone — before factoring in the lost revenue from restricted capacity on winning products.
When Does Liquidating Excess FBA Inventory Make More Financial Sense?
The answer depends on your numbers, but here are the key signals that liquidation is the smarter move:
✔ The product has been sitting for 90+ days with no meaningful velocity improvement At this point the aged inventory clock is ticking and ongoing fees are compounding. A bulk sale now recovers more value than waiting another 90 days.
✔ The product is in a category with high Q4 storage fees If you won’t sell through before October, you’re about to pay peak-rate storage on inventory that isn’t moving at peak-rate sales. Liquidate before the season starts.
✔ The margin after fees no longer makes sense Run the numbers: if your net margin after fulfillment fees, storage fees, aged surcharges, and advertising no longer justifies holding the product, the breakeven case for liquidation becomes clear.
✔ The inventory is blocking your capacity for better-performing SKUs If your excess FBA inventory is consuming capacity that your top sellers need for Prime Day, Q4, or any other peak period, the opportunity cost of holding it exceeds the recovery value of selling it.
✔ The product is discontinued, seasonal, or being delisted There’s no point paying ongoing fees on inventory with no path to profitable sale. Liquidate now and recover whatever value remains.
Amazon’s Liquidation Program vs. Selling to a Direct Buyer
When sellers decide to liquidate, Amazon’s own liquidation program is often the first thing they consider. But it’s worth understanding what that program actually pays.
Amazon’s FBA Liquidations program typically returns 5–10% of the average selling price. For a product with a $30 retail value, that’s $1.50–$3.00 per unit — often less than the cost of the product itself.
Selling your excess FBA inventory directly to a professional bulk buyer consistently recovers significantly more value. Direct buyers evaluate inventory based on real market demand and resale potential — not Amazon’s internal liquidation model designed primarily to clear warehouse space at minimal payout.
According to Investopedia’s inventory management overview, carrying costs for excess inventory typically run 25–30% of the total inventory value annually — which means a fair bulk offer today almost always outperforms the long-term cost of holding and waiting.
Stop Letting Amazon’s Fees Eat Your Margins
The 2026 fee structure sends a clear message: Amazon wants lean, fast-turning inventory. Excess FBA inventory is no longer just a minor operational inconvenience — it’s an active and growing financial liability.
