Amazon Black Friday 2026: Seller Fees & Deadlines

Amazon’s holiday selling season starts well before Black Friday itself.

For sellers using FBA, the dates that matter most are often the deal submission deadline, inventory arrival deadline, and the start of holiday peak fulfillment fees. Missing one of these can mean losing event eligibility or paying higher costs on inventory that arrives too late.

For 2026, Amazon has already published key U.S. seller deadlines and holiday fee information. Here is what sellers should know before planning Black Friday Week and Cyber Monday promotions.

Amazon Black Friday 2026 Deadlines at a Glance

Amazon says Black Friday Week and Cyber Monday deal submissions are open through October 20, 2026. Sellers using FBA should pay particular attention to the October inventory deadlines, since inventory received later may not be positioned in time for the holiday event.

Amazon has announced seller preparation deadlines, but sellers should avoid assuming that the customer-facing Black Friday event will follow exactly the same dates as previous years. The event window can vary from year to year.

1. Black Friday Promotion Fees in 2026

Amazon's 2026 holiday promotion structure applies to Best Deals, Lightning Deals, and Prime Exclusive Price Discounts.

For Black Friday Week and Cyber Monday, the fee structure is:

• $100 upfront fee per promotion
• 1.5% of promotional sales
• Variable fee capped at $5,000 per promotion

Amazon also offered an early-submission incentive: sellers who submitted qualifying Black Friday Week and Cyber Monday deals by September 5 could save $50 on the upfront promotion fee.

For sellers planning multiple promotions, these fees should be included in profitability calculations before setting the final discount.

A product that looks profitable at its normal selling price may have a very different margin after accounting for:

• Event discount
• Amazon referral fee
• FBA fulfillment cost
• Holiday peak fulfillment fee
• Promotion fee
• Advertising spend
• Returns

Instead of planning promotions from revenue alone, calculate the expected contribution margin for each ASIN.

2. FBA Fees Increased in 2026

Amazon increased U.S. FBA fees in 2026 by an average of approximately $0.08 per unit sold.

Most of the 2026 fee changes took effect on January 15, 2026. Amazon also stated that it would introduce no new FBA fee types during the year.

The actual fulfillment cost still varies according to factors such as:

• Product dimensions
• Shipping weight
• Size tier
• Product category
• Inventory age
• Returns
• Inbound placement

That means the $0.08 figure should not simply be added to every product forecast. Sellers should check the current estimated cost for each ASIN.

Amazon's Revenue Calculator and Fee Preview tools can be used to compare FBA costs and estimate profitability at different selling prices.

3. Holiday Peak Fulfillment Fees Start October 15

Black Friday margin planning becomes more important from mid-October.

Amazon's 2026 holiday peak fulfillment fees run from October 15, 2026, through January 14, 2027.

According to Amazon, the holiday increase averages approximately $0.32 per unit above non-peak fulfillment rates. A 3.5% fuel and logistics-related surcharge also applies on top of applicable holiday peak fulfillment fees.

This affects more than Black Friday itself.

The peak period covers much of Q4 and continues into January, so sellers should model the additional cost across holiday inventory rather than applying it only to products sold during the Black Friday event.

A simple calculation is:

Selling Price − Discount − Referral Fee − FBA Cost − Peak Fulfillment Cost − Promotion Fee − Advertising Cost = Estimated Contribution Margin

Run this calculation before increasing discounts simply to qualify for more event visibility.

4. Send Black Friday Inventory Earlier Than You Think

Waiting until November to send Black Friday inventory is risky.

Amazon has published three important inventory deadlines for Black Friday Week and Cyber Monday:

Amazon Warehousing and Distribution

Inventory should arrive by October 14, 2026.

FBA With Minimal Shipment Splits

Inventory should arrive by October 21, 2026.

FBA With Amazon-Optimized Shipment Splits

Inventory should arrive by October 28, 2026.

Amazon notes that fulfillment centers increasingly shift their focus from receiving inventory to fulfilling customer orders as November and December approach.

Inventory can still be received after these dates, but late shipments may not be processed and positioned in time for event demand.

For sellers expecting a significant Black Friday increase, it is safer to work backward from Amazon's arrival deadline rather than using the shipment date.

Remember to leave additional time for:

• Factory preparation
• Freight delays
• Customs clearance
• Domestic transportation
• FBA appointment availability
• Amazon receiving and check-in

5. Prime Big Deal Days Pricing Will Not Hurt Black Friday Deal Pricing

One useful change for sellers participating in both major Q4 events concerns Amazon's pricing lookback.

Amazon says promotional prices used during Prime Big Deal Days will be excluded from the 30-day and 60-day lookback windows used to determine maximum deal pricing for Black Friday Week and Cyber Monday.

This matters because sellers previously had to be careful that an aggressive promotion earlier in the quarter did not create a lower reference point for their later holiday promotion.

For 2026, sellers have more flexibility to run a competitive Prime Big Deal Days offer without automatically undermining Black Friday pricing eligibility.

That does not mean pricing history can be ignored. Amazon still uses reference pricing and other eligibility requirements when evaluating promotions, so avoid artificially increasing prices immediately before a sale.

6. Amazon Business Deals Are Another 2026 Option

Amazon also introduced Amazon Business Deals on August 31, 2026.

These promotions let eligible sellers create limited-time offers specifically for Amazon Business customers.

Amazon says eligible products must:

• Have a rating of at least 3.5 stars
• Be sold in new condition
• Meet pricing requirements
• Meet seller performance requirements

For high-traffic events including Black Friday and Cyber Monday, Amazon Business Deals require a discount of at least 15%.

This can be worth considering for products that naturally sell to businesses, such as office equipment, electronics accessories, packaging supplies, tools, or other frequently reordered products.

It should be treated as a separate promotional strategy rather than a replacement for consumer Black Friday deals.

7. Watch Inventory Health Before Q4

Getting enough inventory into FBA is important, but sending too much inventory creates another problem.

Amazon's FBA cost structure can include:

• Monthly storage costs
• Aged inventory charges
• Returns processing costs
• Removal or disposal costs
• Inbound placement costs

Aged inventory charges can apply when products remain in Amazon fulfillment centers for more than 181 days.

Amazon also uses inventory levels when determining whether low-inventory-level fees apply. The fee is based on historical days of supply and can apply when both short-term and long-term inventory levels fall below the required threshold.

For Black Friday inventory planning, the goal is therefore not simply "send as much as possible."

Forecast separately for:

1. Pre-event demand
2. Black Friday Week
3. Cyber Monday
4. December holiday demand
5. Post-holiday January demand

This makes it easier to avoid both stockouts and excessive leftover inventory.

8. Build Your Black Friday Promotion Around Margin, Not Discount Size

A bigger discount does not automatically create a better campaign.

Before submitting a promotion, sellers should identify the minimum price they can offer while keeping the campaign economically reasonable.

Start with four numbers:

Normal selling price: What does the ASIN usually sell for?

Event price: What will the customer actually pay?

Total Amazon cost: What will referral, fulfillment, peak, promotion, and other applicable fees cost?

Traffic acquisition cost: How much are you prepared to spend on advertising for each sale?

Then compare several discount scenarios rather than choosing one immediately.

For example, a 20% promotion that maintains inventory and advertising efficiency can sometimes produce a healthier result than a 30% promotion that generates large sales volume but very little contribution margin.

Amazon Black Friday 2026 Seller Checklist

Before the event, confirm that you have:

• Reviewed your ASIN-level FBA costs
• Included holiday peak fees in your margin forecast
• Submitted eligible deals before the Amazon deadline
• Checked current promotion eligibility inside Seller Central
• Planned inventory around Amazon's October arrival deadlines
• Reviewed historical sales before forecasting Q4 inventory
• Checked pricing and reference-price requirements
• Prepared Sponsored Products and other advertising campaigns early
• Verified listing images, titles, bullets, and product information
• Created a plan for replenishment during November and December
• Set a minimum profitable promotional price for each ASIN

The biggest Amazon Black Friday changes in 2026 are less about a single new rule and more about timing and unit economics.

Promotion submissions close weeks before Black Friday. Inventory needs to arrive even earlier. Holiday fulfillment costs begin in mid-October, and promotion fees need to be included alongside advertising and discounts.

For most sellers, the best preparation is therefore straightforward: calculate profitability at the ASIN level, send inventory early enough to meet Amazon's published deadlines, and confirm promotion eligibility directly in Seller Central before committing to a discount.

Amazon can update event requirements, dates, and eligibility rules as the holiday season approaches, so sellers should treat Seller Central as the final source of truth for their account and marketplace.
