Your Amazon holiday sales are increasing. Customers are placing more orders, your products are moving faster, and your advertising campaigns are bringing in traffic. Sounds great, right? But here's something many sellers overlook.
What if you're selling more products but keeping less profit?
With Amazon's 2026 holiday peak fulfilment fees now in effect, sellers in the US and UK need to pay closer attention to their costs.
And here's the important part.
The rules aren't exactly the same in both marketplaces.
Let's break down what's changing, who is affected, and how to protect your margins.
๐ What Are Amazon FBA Peak Fees?
Amazon FBA, or Fulfilment by Amazon, allows sellers to store inventory in Amazon's fulfilment centres.
Amazon then handles picking, packing, delivery and certain customer service processes.
During the busy holiday season, fulfilment and transportation demand increases.
To help cover these seasonal operating costs, Amazon applies additional peak fulfilment charges to eligible orders.
For 2026, the peak-fee period runs from 15 October 2026 to 14 January 2027.
But the actual fee depends on your marketplace, product size, weight and other eligibility rules.
1. Amazon US FBA Peak Fees: What's Changing?
For US sellers, the 2026 holiday peak fees apply to FBA and several related fulfilment services.
Amazon has also maintained a 3.5% fuel and logistics-related surcharge, which applies to the relevant fulfilment fees.
Here's one example from Amazon's published rate card.
A qualifying large standard-size product, priced between $10 and $50, with a shipping weight between 1.5 and 1.75 pounds:
Non-peak fulfilment fee: $6.14
Peak fulfilment fee: $6.53
Increase: $0.39 per unit
These figures exclude the additional fuel and logistics surcharge.
Now imagine selling 5,000 units.
That $0.39 increase adds approximately $1,950 in base fulfilment costs alone.

Here's another detail worth knowing.
In the US, the relevant peak rate is determined when inventory leaves Amazon's fulfilment centre.
So even if a customer orders before 15 October, a shipment dispatched on or after that date can attract the peak fee.
Check the official Amazon US FBA fee schedule for your product's exact rate.
2. Amazon UK FBA Peak Fees: What Sellers Need to Know
UK sellers also face seasonal fulfilment charges, but the eligibility rules are different.
Amazon's 2026 festive peak fee applies to certain locally fulfilled and remote-fulfilled orders delivered to UK customers.
In the UK, affected product types include:
Large and extra-large envelopes.
Small parcels.
Standard parcels.
However, oversize and low-price FBA items are excluded from this specific festive peak fee.
For example, Amazon's UK table lists one qualifying small parcel tier at ยฃ2.83 during the non-peak period and ยฃ2.94 during peak season.
That's an additional ยฃ0.11 per unit.
Another important difference?
UK peak-fee eligibility is based on the delivery date rather than the US shipment-date rule.
You can review the official Amazon UK peak fee guidance.
3. Why Small Fee Increases Can Become Expensive
A few extra pence or cents might not sound serious.
But the impact changes when you're selling thousands of units.
Imagine you're already paying for:
Product manufacturing.
Amazon referral fees.
FBA fulfilment.
Inventory storage.
Advertising and promotions.
Returns and other operating costs.
Now add seasonal fulfilment charges.
Suddenly, your profit margin becomes smaller.

More orders don't automatically mean more profit.
That's why peak fees should be included in your product-level profitability calculations.
4. Five Ways to Protect Your FBA Profit Margins
You can't simply ignore Amazon's seasonal fees.
But you can prepare your business to manage them.
1. Review your fulfilment costs
Use Amazon's Revenue Calculator and fee preview reports to compare non-peak and peak costs.
2. Identify low-margin products
Find products where higher fulfilment fees could make sales unprofitable.
3. Review your pricing strategy
Check whether your current prices and promotions still support healthy margins.
4. Improve inventory planning
Avoid sending unnecessary stock that creates additional storage costs.
5. Connect advertising with profitability
Before increasing PPC spending, make sure the products you're promoting can absorb the extra costs.
