The short version for your margin
Amazon's announcement, sent to sellers on November 5, 2026, changes three things: what it charges to fulfill an order, how it charges for storage, and when it decides your stock is too thin. The fuel and logistics surcharge is the one item staying put. Most changes start on January 15, 2027, and the storage and low-inventory changes start on February 1, 2027.
The headline number is an average, and averages hide the SKU that hurts. Amazon puts the typical rise in FBA fulfillment fees at $0.19 per unit sold, about 0.8% of the average item's selling price. It also says the changes are built so each fee tracks what that product actually costs to fulfill, which means some fees go up and some go down. Whether you gain or lose depends on your size tiers and price points.
What changes, and when
| Date | Change | Where it hits your P&L |
|---|---|---|
| January 15, 2027 | FBA fulfillment fees reset. Average rise of $0.19 a unit, but some products go down. | Per-unit fulfillment cost, every order |
| Unchanged | Fuel and logistics surcharge stays as it is; Amazon will keep reviewing it. | No new cost, but it can still move later |
| February 1, 2027 | Storage utilization surcharge eliminated. Aged inventory surcharge merged into monthly storage as one age-based rate. | Monthly storage line, especially for slow stock |
| February 1, 2027 | Low-inventory-level fee only applies below 28 days of supply, using shipments before and after the assessment date. | Replenishment timing and the fee line for thin SKUs |

FBA fulfillment fees: check SKU by SKU
Because the $0.19 is a blended figure, do not paste it into every listing. Amazon's letter points to two tools for the real answer: a new Fee Change Comparison dashboard in Profit Analytics, which shows the effect on your account and on individual products, and the Revenue Calculator for modeling scenarios. Start there, sort by units sold, and look at the SKUs that carry most of your volume first.
The practical question is not whether the average goes up but which of your products sit on the wrong side of it. A low-priced, high-volume item with a thin margin can be hurt by a small per-unit change far more than a premium item can. If you price to a target margin, re-run the numbers in the Amazon fee calculator once you know your new per-unit fee, and use its target price mode to see what price keeps your margin. The calculator still runs on the 2026 rate card until the new one is loaded.
Storage: slow stock gets pricier, fast stock does not
The storage change is a simplification. Today there are separate add-on charges for using a lot of space and for holding old units. In February both stop being add-ons: the utilization surcharge is dropped, and the age charge becomes part of one monthly rate that rises with how long a unit has sat. Amazon says stock that sells through in under six months pays the same or less, and older stock pays more.
Two consequences are worth planning around. First, dropping the utilization surcharge removes one reason to hold back on a big inbound before a busy event; Amazon itself frames it as making it easier to stock up for high-demand periods. Second, the cost of a slow SKU becomes steadier and easier to forecast, but it climbs the longer you leave it. If you carry units that have been in the warehouse a long time, decide before February whether to run a promotion or send them out through a removal order, and compare that one-time cost with the ongoing age-based rate.
The low-inventory-level fee gets harder to trigger
This fee is aimed at sellers who run out of stock. Under the current approach it looks backward, at trailing 30- and 90-day sales. From February 1 it looks at actual shipments in the four weeks before and the four weeks after the assessment date, and it only applies when you hold fewer than 28 days of supply. Amazon says the second look is meant to separate real ongoing demand from a one-off spike, an end-of-season item or a product being wound down.
For a seller, that is mostly good news for seasonal and discontinued lines, which are the ones the old rule tended to catch. It does not help a fast mover that keeps selling and keeps running thin, so the replenishment habit still matters. Check days of supply against 28 for your best sellers, and see how it lines up with your cash flow before the next restock.
What to do before the dates
- Pull the Fee Change Comparison for your account and note the SKUs whose fee goes up.
- Reprice, or push on your supplier cost, where the new fee takes a SKU below your margin floor.
- List inventory that has sat in the warehouse a long time and decide what to do with it before February 1.
- Check days of supply on your top sellers against the 28-day line.
- Compare the new fulfillment card with the holiday peak card you are paying now, not only with the non-peak one.
What this page does not cover
Amazon's announcement also refers to a fuller summary with additional updates for small and large standard-size items, items priced above $50, "Buy X, Get Y" promotions, Multichannel Fulfillment, and Amazon Warehousing and Distribution. The letter itself gives no figures for those, so we do not list any. We will add the rate details here once we have checked them against Amazon's published tables.
Frequently asked questions
When do Amazon's 2027 fee changes take effect?
Most changes take effect on January 15, 2027. The storage changes and the new low-inventory-level fee test take effect on February 1, 2027.
How much will FBA fulfillment fees go up in 2027?
Amazon says fulfillment fees will rise by $0.19 per unit sold on average, about 0.8% of the average item's selling price. The change is not uniform: some products pay more and others pay less, depending on size and price, so your own SKUs can land well away from the average.
Is the fuel and logistics surcharge changing?
No. Amazon is holding the surcharge it introduced in April 2026 where it is and says it will keep reviewing it as fuel and trucking costs move.
What happens to the storage utilization surcharge and the aged inventory surcharge?
From February 1, 2027 the storage utilization surcharge is eliminated, and the aged inventory surcharge is folded into monthly storage fees as a single age-based rate. Amazon says inventory that turns in under six months sees flat or lower fees, while aged inventory pays more.
How does the new low-inventory-level fee test work?
From February 1, 2027 the fee applies only when your inventory is below 28 days of supply, judged on shipments in the four weeks before and after the assessment date. Today it uses trailing 30- and 90-day sales.
