Amazon's fee changes stack new per-unit costs: the January 15, 2026 fulfillment update (about +$0.08 per unit on average), a 3.5% fuel and logistics surcharge on fulfillment fees from April 17, 2026, inbound placement fees ($0.14–$1.90/unit for standard size on minimal splits, up to $6.50 for bulky; Extra-Large pays none) and the low-inventory-level fee ($0.32–$2.09 per unit shipped when both the 30- and 90-day days of supply are under 28). What they add depends on each SKU's size, weight, price and velocity. The shift to DD+7 disbursements — funds available 7 days after confirmed delivery — extends cash conversion cycles. Every seller should recalculate true unit economics with current inputs.
Amazon has made two significant changes to how FBA sellers experience fees and payments over the past 12 months — and most sellers have not fully accounted for either of them in their financial planning. The first is Amazon's January 15, 2026 fee update, which raised fulfillment fees, split out a new Small Bulky tier and reset the inbound placement rate card, followed by a 3.5% fuel and logistics surcharge on fulfillment fees from April 17, 2026. The second is a change to the disbursement cycle — the shift to DD+7 (Delivery Date plus 7 days) — that has created unexpected cash flow pressure for sellers who weren't prepared for it.
Together, these changes have made the per-unit economics of FBA materially different from what many sellers modeled even 18 months ago. This guide breaks down exactly what changed, how to calculate the real impact on your margins, and what operational adjustments are worth considering.
What Changed in Amazon FBA Fees
Amazon's own 2026 summary says 2025 brought no increase in US referral or FBA fees. The increases arrived with the January 15, 2026 update: fulfillment fees rose about $0.08 per unit on average, the old Large Bulky tier was split into Small Bulky and Large Bulky, and the inbound placement rate card was reset. Here are the key changes and their practical implications.
2026 fulfillment fees
The fulfillment fee is set by size tier (small standard, large standard, Small Bulky, Large Bulky or Extra-Large), by shipping weight (unit weight for small standard; the greater of unit and dimensional weight above that) and by price band: items under $10 get Low-Price FBA rates, $10–$50 pays the standard rate, and standard-size items over $50 pay $0.26 more. Sample 2026 non-peak rates at $10–$50, before the surcharge:
- Small standard, 2 oz or less: $3.32 (up to $3.96 at 14+ to 16 oz)
- Small standard, 6+ to 8 oz: $3.54
- Large standard, 8+ to 12 oz: $4.20
- Large standard, 1+ to 2 lb: $5.04–$5.82 by quarter-pound band
- Large standard, 2+ to 3 lb: $5.92–$6.67
- Large standard over 3 lb: $6.97 plus $0.08 per 4 oz above the first 3 lb ($12.41 at 20 lb)
- Peak card for units shipped October 15, 2026 – January 14, 2027: higher on every band Amazon lists, for example $3.51 for small standard 2 oz and $4.48 for large standard 8+ to 12 oz
- A 3.5% fuel and logistics surcharge on the fulfillment fee from April 17, 2026, on both cards

Inbound placement fees
One of the most significant newer costs is the inbound placement fee, introduced in March 2024 — a charge for "Minimal Shipment Splits," the placement option where sellers ship to the fewest locations (generally one) and Amazon redistributes inventory across its network. This fee — reset in the January 15, 2026 rate update to $0.14–$1.90 per unit for standard-size items, $1.10–$5.95 for Small Bulky and $1.30–$6.50 for Large Bulky, with no fee on Extra-Large — effectively means Amazon is charging for the distribution service it previously included in its fulfillment fee.
Sellers who ship directly to multiple fulfillment centers (using Amazon-optimized splits, which need at least five identical cartons or pallets per item and are offered only when Amazon makes them available) avoid this fee — but this requires more complex logistics coordination and typically higher freight costs. For sellers with high-volume SKUs and established 3PL relationships, the math often favors direct distribution. For smaller operations, the inbound placement fee is often the path of least resistance despite the added cost.
Low-inventory-level fees
The low-inventory-level fee launched April 1, 2024 (Amazon credited back April's charges and began charging on May 1, 2024) and changed on January 15, 2026: it is now measured per FNSKU, it covers Small and Large Bulky as well as standard-size products, and Grocery is exempt. You pay it per unit shipped, $0.32–$2.09 depending on size tier, when both your 30-day and your 90-day historical days of supply (sellable units across Amazon's US network divided by units shipped) fall below 28 days. There is one threshold for every category, and products that sold fewer than 20 units in the past 7 days are exempt.
This fee has caught many sellers off guard because it is counterintuitive: Amazon is penalizing you for not having enough inventory in their network. From Amazon's operational perspective, low-inventory products are harder to fulfill efficiently because they cannot be distributed across fulfillment centers. For sellers, it creates pressure to maintain higher FBA stock levels — which in turn increases storage fees and cash tied up in inventory.
The low-inventory-level fee, the inbound placement fee, the 2026 fulfillment increases and the 3.5% surcharge stack on the same unit. For products with margins already under pressure, together they can flip a profitable SKU to break-even or worse, so price them per ASIN rather than trusting an average.
The DD+7 Payment Change: What It Means for Cash Flow
Historically, Amazon disbursed seller funds on a rolling 14-day schedule — twice per month, regardless of when individual orders were delivered. In 2025, Amazon transitioned to a Delivery Date + 7 (DD+7) disbursement model, which ties fund availability to when each order was delivered rather than to a fixed calendar schedule.
How DD+7 actually works
Under DD+7, funds from a sale are not available for disbursement until 7 days after the order is confirmed delivered. This means: (1) orders with longer fulfillment timelines have longer cash conversion cycles, (2) disbursements are no longer predictably twice-monthly — they reflect the rolling delivery pattern of your order flow, and (3) seasonal spikes in sales can create a delayed spike in cash availability.
Real impact for FBA sellers
For sellers ordering inventory from Chinese manufacturers with 45–60 day lead times, the cash cycle now looks like this: you pay for inventory 60 days before it arrives at FBA. It arrives, is received (5–10 days), sells (variable), is delivered (1–5 days via FBA), and funds are available 7 days after delivery. A product that sells within its first week at FBA could still have a 75–80 day cash cycle from supplier payment to cash in hand.
- Review your reserve balance in Seller Central — this is now meaningfully higher for many sellers because more funds are "in transit" under DD+7
- Model your cash flow using delivery date rather than order date — many seller accounting tools have not been updated for this change
- Consider whether a credit facility or inventory financing line is appropriate given the extended cash cycle
- For high-velocity products, the impact is lower because deliveries are more continuous — the real pain is felt by sellers with lumpy, seasonal, or lower-velocity sales patterns
The interaction with the A-to-Z guarantee hold period
DD+7 interacts with Amazon's existing A-to-Z Guarantee claims window in a way that further extends the hold period for some orders. If a buyer opens an A-to-Z claim, the funds associated with that order can remain on hold for the duration of the claims process — which can extend the cash conversion cycle significantly beyond the standard 7-day DD+7 window.
How to Recalculate Your True FBA Economics
Given these fee changes, every seller should run a fresh unit economics calculation for every active ASIN. The inputs have changed enough that 2023 or 2024 margin models are no longer reliable.
- 1Pull your current FBA fee per unit from the FBA Revenue Calculator — use current dimensional weight, not historical estimates
- 2Add the inbound placement fee if you are using Minimal Shipment Splits (check your shipping plan settings)
- 3Calculate your average storage fee based on your average monthly inventory level and current storage rates
- 4Estimate your low-inventory fee exposure by checking your inventory health dashboard for any flagged ASINs
- 5Add these costs to your Cost of Goods Sold, Amazon referral fee, and any advertising spend to get your true all-in cost per unit sold
- 6Compare your all-in cost to your current selling price and calculate the margin that remains
For products where the margin after this calculation is below 15%, you have a pricing or sourcing decision to make. Raising prices, renegotiating COGS with your supplier, or discontinuing the ASIN are all legitimate responses — but they require knowing the real number first.
Once you've recalculated, benchmark the result: the 2026 FBA profit-margin benchmarks by category lay out the 100→15 fee waterfall and the net-margin bands healthy sellers hit in each category.
What Sellers Are Doing to Adapt
Sellers who have adapted most successfully to the 2025–2026 fee environment have taken specific operational steps that are worth considering:
- Optimizing product packaging dimensions to reduce dimensional weight — even a 10% reduction in package size can move a product to a lower fee tier
- Shifting high-velocity SKUs to direct FC placement to avoid inbound placement fees
- Increasing reorder frequency to maintain inventory levels above the low-inventory threshold without holding excess stock
- Evaluating FBM as a parallel channel for products with higher price points where the margin math supports it
- Using Amazon's new FBA Reimbursement program aggressively — Amazon loses and damages inventory regularly, and many sellers are not claiming their full entitlement
Amazon adjusts its fee structure periodically. Sellers who build fee tracking into their quarterly business reviews — rather than treating FBA fees as a fixed background cost — consistently outperform those who recalculate only when they notice a margin problem.
Tools for Tracking the Real Impact
Managing FBA unit economics in 2026 requires better tooling than most sellers currently use. Seller Central's built-in analytics do not automatically surface the combined effect of fulfillment fee increases, inbound placement fees, low-inventory fees, and DD+7 cash flow changes on a per-ASIN basis. Dedicated Amazon analytics and advertising management tools that integrate with SP-API can pull this data automatically and surface margin warnings before they become a problem.
The most important metric to track going forward is not revenue — it is contribution margin per unit, calculated after all Amazon-side costs including storage, fulfillment, and inbound fees. Sellers who track this number weekly make better decisions about pricing, restocking, and ASIN mix than those who track it quarterly.
