Amazon just told sellers what FBA will cost in 2027. Fulfillment fees go up an average of $0.19 per unit on January 15. Storage gets rebuilt on February 1 into one age-based rate. And the low-inventory-level fee finally starts looking at what actually sells after the check, not just before it. Average is the key word. Your number could be higher, lower, or flat depending on your mix.
What happened (confirmed)
From Amazon's November 5, 2026 letter to US selling partners:
- FBA fulfillment fees rise an average of $0.19 per unit sold, about 0.8% of the average item's selling price. Some products go up, some go down, so each fee tracks Amazon's cost to fulfill that product more closely.
- Most changes take effect January 15, 2027.
- The FBA fuel and logistics surcharge introduced in April 2026 stays where it is. Amazon says it will keep reviewing it.
- Effective February 1, 2027, the storage utilization surcharge goes away.
- Also February 1, the aged inventory surcharge is removed and folded into monthly storage as a single, age-based rate. Amazon says that means flat or lower fees for inventory that turns in under six months and higher fees for aged inventory.
- The low-inventory-level fee will apply only when inventory falls below 28 days of supply based on actual shipments in both the four weeks before and the four weeks after the assessment date. Today it uses trailing 30- and 90-day sales.
- Amazon added a Fee Change Comparison dashboard in Profit Analytics to show the impact at the account and product level. The Revenue Calculator models scenarios.
- The full fee summary also covers updates for small and large standard-size items, items priced above $50, "Buy X, Get Y" promotions, Multichannel Fulfillment, and Amazon Warehousing and Distribution.

Why this matters
My read: the 19 cents is the headline, but storage is the real story. Amazon is collapsing two surcharges into one rate keyed to how long a unit sits. That rewards brands that turn inventory and punishes brands sitting on slow stock. Same incentive as before, just one number on the bill instead of three stacked calculations.
Killing the utilization surcharge matters for planning. That fee made it expensive to stock up ahead of big events. Once it is gone, the math on building inventory before Prime Day or a Q4 run gets easier, as long as that inventory actually sells through inside six months.
The low-inventory fee change is a real fix. Under the trailing-sales test, a one-week spike or a product you were winding down could trip a fee for a SKU you never meant to restock. Looking four weeks forward should cut those false hits. It also means the charge shows up later, because Amazon needs the forward weeks of sales to calculate it.
And remember this lands on top of everything else. The fuel and logistics surcharge is not going away yet. For low-price items, a 19 cent move on the average is not the same as 0.8% of your price. Run your own SKUs.
Who it affects
- Every US FBA seller, especially brands with thin margins on low-priced items where cents per unit move contribution margin.
- Brands carrying slow or seasonal inventory past six months, which will face higher age-based storage.
- Brands that got hit by low-inventory-level fees on end-of-season or end-of-life SKUs.
- Sellers using Multichannel Fulfillment, AWD, or "Buy X, Get Y" promotions, which have their own updates in the full summary.
What sellers should do now
- Open the Fee Change Comparison dashboard in Profit Analytics and pull your top SKUs by volume. Find out which ones go up, which go down, and by how much.
- Re-run contribution margin on any SKU where the new fee changes your floor. Decide on pricing before January 15, not after the first settlement report surprises you.
- Pull an aged inventory report now. Anything you do not expect to sell through inside six months is a candidate for a Q4 push, a removal, or a liquidation plan before February 1.
- Rebuild your 2027 inbound plan around the age-based rate. With the utilization surcharge gone, deeper buys ahead of events can work, but only for SKUs with proven velocity.
- Read the full summary for the $50-plus price tier, size tier, MCF, and AWD changes if any of those touch your catalog.
