If you sell on Amazon FBA, check your seller central this week. Amazon ran its monthly aged inventory assessment on May 15, and the charges hit accounts between today and Friday. This is only the second time these charges have posted under the new 181-day threshold that took effect April 17, which means a lot of operators are about to see line items on their statement they didn’t see in 2025.
Here at Ecommerce Paradise, I run a marketing agency for high-ticket dropshipping stores, and most of my clients sell off-Amazon by design. But Amazon FBA still shows up in almost every multi-channel conversation we have, because even high-ticket operators use FBA for replenishment SKUs, accessory cross-sells, or test pools before they commit to authorized dealer agreements with their primary suppliers. The fee changes that landed in the last six weeks affect all of those use cases.
This is the steepest stacking of FBA fulfillment-side fees Amazon has rolled out in a single quarter since the 2024 inbound placement restructure. The 3.5% fulfillment surcharge that hit FBA on April 17 expanded to Multi-Channel Fulfillment and Buy with Prime on May 2. The aged inventory threshold moved 90 days earlier in the year. A brand new 15-month tier got bolted onto the storage stack at $0.35 per unit. None of these alone would be a panic event. Stacked together, hitting accounts in the same monthly cycle, they reshape what every FBA seller’s cost-per-unit math looks like for the rest of the year.
I’ll walk through what’s actually on this week’s statement, how we got here, and what I’m telling my clients to do before the next assessment runs in 30 days.
Margin compression like this is exactly why proper LLC formation matters more than people think. The pass-through tax structure and the deductions only work if you’re actually formed, and LegalZoom is what I send most operators to for the combined LLC formation, EIN, and registered agent package.

What Just Hit Your Statement
The May 15 monthly assessment is the trigger event. Amazon assesses aged inventory surcharges on the 15th of each month and posts the actual charges to seller accounts between the 18th and 22nd, according to Amazon’s own aged inventory surcharge documentation. For most FBA accounts, the charges show up Tuesday through Thursday this week.
Three structural changes are stacking on this cycle’s statement, and a fourth base-fee adjustment sits underneath all of them. Here’s what each one actually does.
The 181-Day Threshold
The aged inventory surcharge used to kick in at 271 days. Effective April 17, 2026, that threshold moved to 181 days, which is 90 days earlier than the prior rule. Per eFulfillment Service’s full 2026 fee breakdown, this is the most consequential structural change to the surcharge in five years. Any unit that’s been in an Amazon fulfillment center for 181 days or more starts accumulating the fee, and the fee scales upward as inventory ages further into the tier bands.
For sellers who took a conservative inbound stance in Q4 2025 and have inventory still sitting from December restocks, this is the first month they’re crossing into the new band. The cost isn’t just the surcharge itself. It’s the fact that they were planning around the old 271-day rule and didn’t liquidate when they otherwise would have.
The New 15-Month Tier
Amazon added a brand new aged-inventory tier for inventory stored 15 months or longer. The fee is $0.35 per unit or $7.90 per cubic foot, whichever is greater, on top of the existing tier surcharges. For oversized SKUs like furniture, fitness equipment, and outdoor gear, the kinds of products my high-ticket niches list tends to live in, the cubic-foot calculation usually wins.
What that means in practice: a deadstock unit can hit $8 or more per month in storage costs alone before you factor in liquidation losses. Stretch that across 50 deadstock SKUs and you’re looking at a four-figure monthly drag with zero revenue offset.
The 3.5% Fulfillment Surcharge Now Includes MCF
The 3.5% fulfillment surcharge that hit core FBA on April 17 expanded to Multi-Channel Fulfillment and Buy with Prime on May 2. If you run a Shopify store that uses MCF to fulfill orders, those orders are now eating the surcharge too. On a $15 fulfillment fee, that’s 53 cents per order, which sounds small in isolation. Multiply it across an MCF-heavy DTC operation doing 1,500 orders a month and you’re at $795 in new monthly drag with no corresponding revenue lift.
The Base Fee Increase
On top of all that, Amazon’s published base FBA fee increase for 2026 averages $0.08 per unit. Amazon frames this as below carrier inflation, and on a per-unit basis that framing is technically accurate. The issue isn’t any single one of these changes in isolation. The issue is they’re all hitting the same statement, in the same week, for the second monthly cycle since the threshold drop.
How Amazon Framed It vs What Sellers Are Seeing
Per Amazon’s official 2026 fee update, the company describes the changes as significantly less than inflation and notes that no new fee types are being introduced. The framing misses the timing compression. Sellers are absorbing three concurrent structural changes on the same monthly statement, in the same quarter, with no advance notice on the MCF expansion until late February.
The other thing Amazon’s framing doesn’t capture is who absorbs the hit hardest. Per Marketplace Pulse’s seller index, 38% of Amazon sellers are already classified as distressed and only 23% are genuinely thriving. The aged inventory surcharge is regressive against sellers carrying slow movers, which tilts disproportionately toward smaller operators and newer sellers who haven’t refined SKU discipline. The Q1 2026 paid-units mix from third-party sellers also dropped to 60% from 62% the quarter before, the first two-quarter consecutive decline Amazon has reported on that metric since 2004.
How We Got Here
Amazon’s fee architecture didn’t always look like this. To understand why this week’s statement looks the way it does, you have to go back about 18 months.
The 2024 Inbound Placement Fee
In early 2024, Amazon introduced the inbound placement fee, which charges sellers for shipping inventory to a single fulfillment center instead of pre-distributing it across multiple Amazon nodes. That was the first major shift in how FBA cost-of-goods worked. Sellers who didn’t restructure their inbound process ate 8-12% margin hits on slow SKUs for an entire quarter before catching up. It also set the precedent for Amazon offloading more fulfillment-side cost decisions onto sellers.
The 2025 Pause and the 2026 Restart
Amazon held the referral fee structure flat in 2025 after vocal seller pushback. That gave the impression of stability. What was actually happening underneath was a quiet reorganization of the storage and aged-inventory side of the cost stack. The 2026 announcement bundled four separate changes into a single update: base fee adjustments, aged-inventory threshold drop, new 15-month tier, and the 3.5% surcharge. That bundling cadence is unusual for Amazon. Historically, fee changes get rolled out one at a time with 90-day notice.
The MCF Surprise on May 2
The MCF and Buy with Prime expansion of the 3.5% surcharge wasn’t part of the original 2026 fee announcement. It got announced separately in late February, with an effective date of May 2. For multi-channel sellers running Shopify storefronts on top of FBA fulfillment, this was the most consequential change of the bunch, because the surcharge now hits orders that never touch Amazon’s actual customer marketplace. As Retail Dive covered in the context of Walmart’s competing marketplace push, this is also the moment competitive pressure on Amazon’s fulfillment-as-a-service pricing started to ease, not tighten.
Why the Threshold Drop Matters Most
Of all the 2026 changes, the 181-day threshold drop has the biggest long-term operator impact. Storage rates can be modeled. Surcharges can be priced into product cost. But shrinking the window between inbound and surcharge-eligibility forces a fundamental change to how sellers plan inventory cadence. Seasonal products that used to have a comfortable 9-month sell-through window before storage fees kicked in now have 6 months. SKUs that take 270 days to liquidate cleanly now have 180.
That’s the structural change that didn’t get enough attention when the announcement dropped in February, and it’s the one whose effects are now showing up on May statements.
Why This Matters for Your Store
Let me put rough numbers on this so it stops feeling abstract.
If you’re running an FBA operation at 1,000 units of monthly velocity with an average ASIN value of $35 and a 20% gross margin, you’re netting $7 per unit before this week’s surcharge cycle. The combined 3.5% fulfillment surcharge plus average $0.08 base fee increase is hitting you for roughly $0.61 per unit, which compresses your gross margin to about 18.3%. That’s not catastrophic. It’s a manageable adjustment.
But layer in the aged inventory exposure and the math changes. If even 5% of your active SKUs are sitting past the 181-day mark, the new tier surcharges plus the existing storage fees can wipe out 35-50% of your gross profit on that subset of inventory in a single month. For sellers operating on tight cash flow cycles, that turns a profitable SKU into a break-even or unprofitable one almost instantly. The damage isn’t averaged across the catalog. It’s concentrated on the SKUs you were already going to liquidate, just earlier than you planned.
For high-ticket sellers, the math actually works out differently. On a $1,200 ASIN with a 22% gross margin, the 3.5% surcharge on a $30 fulfillment fee is $1.05 per order. That’s noise on a $260-plus gross profit per order. The aged-inventory exposure can still hurt if you carry large boxed inventory, but high-ticket dropshippers who pull from authorized dealer suppliers generally don’t sit on FBA inventory for 6 or more months because the supplier ships direct anyway. This is one of the reasons I’ve spent the last decade telling people that high-ticket dropshipping insulates you from this category of platform pain.
If you’re running a hybrid model with a Shopify storefront and MCF fulfillment for an Amazon-listed catalog, the MCF expansion is where the bleeding shows up. On Shopify, you’re paying Shopify’s transaction stack, your payment processor’s percentage, and now Amazon’s 3.5% on the MCF leg. Per order, your fulfillment cost just moved from a known quantity to a slightly worse known quantity, and the cumulative drag over 12 months adds up.
Here’s the deeper point that I tell my clients during scaling reviews. Margin compression like this is exactly why your business formation matters. A proper LLC with the right pass-through structure gives you deductions on inventory, fulfillment costs, and the surcharge itself. For US sellers, I send most people to LegalZoom because they bundle the EIN and registered agent with the formation, and the turnaround is fast. Without proper formation, you’re not capturing the deductions that partially offset Amazon’s fee hike.
The same logic applies to bookkeeping. Tracking FBA fees correctly down to the SKU level is the only way to know which products are actually profitable post-surcharge. Most generic accounting tools don’t break this out. Finaloop is built specifically for ecommerce books and reconciles Amazon settlements automatically, which is the difference between knowing your real per-SKU margin and guessing at it.
For international sellers, the payout side gets tighter too. Wise gives you the multi-currency receiving account that lets you keep Amazon’s USD payouts in USD instead of forcing an FX conversion at unfavorable rates every settlement cycle. On a $50K monthly payout, the FX drag alone can add up to more than the new base fee increase.

What To Do This Week
I’ll keep this concrete. These are the moves I’m telling my agency clients to run this week before the next assessment cycle on June 15.
- Pull your FBA fee preview report and aged inventory report this week. Both reports live in Seller Central and reflect the new threshold structure. The aged inventory report shows you which SKUs are within 30 days of the next surcharge band. Use that as your shortlist for action by June 1. If you’re not running these reports monthly, set a recurring calendar reminder right now.
- Liquidate or remove anything sitting past 150 days. The clock to the 181-day surcharge starts at 150 days for any unit that hasn’t moved. Either run a price drop to clear it, list it on a secondary channel like a Shopify storefront, or use Amazon’s removal order option before the next assessment. Removal beats sitting and paying compounding surcharges every cycle.
- Audit your inbound cadence. If you’re still shipping inventory in 12-month tranches based on pre-2026 thinking, cut that to 6-month tranches and use the saved cash flow to test new SKUs. The threshold drop makes long inbound cycles structurally unprofitable for slow movers. Tighter inbound also lets you respond to demand signals faster.
- Set up real ecommerce bookkeeping if you don’t have it. Tracking FBA fees at the SKU level is non-negotiable now. Finaloop or a similar ecommerce-specific tool catches surcharge line items that generic bookkeeping software misses. You can’t price-correct what you can’t see, and the surcharge line items hide easily in standard settlement reports.
- If you’re not properly formed, fix that this month. Margin compression hurts most when you’re missing the pass-through deductions that offset it. LegalZoom bundles the LLC formation, EIN, and registered agent in one workflow with a fast turnaround. Talk to your accountant about Section 199A deductions and how the surcharge gets categorized for tax purposes.
- Diversify off-Amazon if you haven’t started. A direct storefront for your same catalog gives you a hedge against future fee increases. For high-ticket operators, the math has been favoring direct supplier relationships for years. Tools like Inventory Source connect to multi-supplier feeds if you want diversification without warehousing inventory yourself.
- Build the email list you’ve been putting off. Direct customer relationships are your only real hedge against platform fee changes. I use Omnisend for my own stores because it handles ecommerce flows without the price escalation of competitors. Even a 500-person list at 25% open rate beats waiting for Amazon’s next fee announcement to redirect your strategy.
Frequently Asked Questions
Does this affect FBM (fulfilled by merchant) sellers too?
The 3.5% surcharge and aged inventory changes only apply to FBA. FBM sellers escape the fulfillment-side fee stack but still pay the standard Amazon referral fee, which sits at 8-15% depending on category. If you’ve been thinking about moving slow SKUs to FBM to dodge the new aged inventory tier, the math usually works for any unit that hasn’t sold in 6 months. The trade-off is that you absorb the shipping logistics yourself.
How does this compare to selling on Walmart Marketplace or eBay?
Walmart’s WFS fees came in lower than Amazon FBA for most categories even before the surcharge stack, and Walmart hasn’t run a comparable fee restructure in 2026. eBay has run flat for FBA-equivalent fulfillment options. The trade-off is volume. Amazon still moves 5-7 times what either alternative does on most categories, per Marketplace Pulse’s marketplace rankings. Use them as diversification, not as a one-for-one replacement.
I’m new and not sure if I should even start with FBA in 2026.
For low-ticket, high-velocity, fast-moving SKUs, FBA still wins on most metrics despite the fee changes. For high-ticket and slow-moving categories, the math has favored direct supplier fulfillment via high-ticket dropshipping for years, and the gap just widened. Match the business model to your product, not the other way around.
Does this change anything for my Shopify store if I don’t use MCF?
Not directly. If your Shopify orders ship from your own warehouse or via a non-Amazon 3PL like ShipBob, the 3.5% surcharge doesn’t touch you. The only Shopify-side concern is if you’ve been using MCF as a fallback for inventory you also list on Amazon. Run the math on whether moving to a dedicated 3PL is cheaper now under the new surcharge structure.
Will Amazon roll this back if sellers push back enough?
Probably not. Amazon held the referral fee flat in 2025 after seller pushback, but that pushback was about a different fee category. The 2026 changes are framed as operational cost recovery rather than discretionary increases. The third-party seller mix dropping for two consecutive quarters suggests Amazon expects some seller attrition and is okay with it. Plan around the new structure rather than waiting for a reversal that probably isn’t coming.
What’s the biggest mistake sellers will make this week?
Doing nothing. The cycle nature of the aged-inventory surcharge means the same SKU that crossed the 181-day mark this month will hit the next tier in 30 days. Sellers who absorb the May 18 charge without changing their inventory cadence will see a worse June statement and a worse July statement until they liquidate. The cost compounds every cycle.
Does forming an LLC actually help with this kind of margin compression?
It doesn’t change Amazon’s fees, but it changes how the fees and inventory get tax-treated on your end. Pass-through structures plus Section 199A deductions plus proper bookkeeping can recover 3-5% of effective margin annually for properly structured sellers. The full business formation guide walks through which structures fit which seller sizes.

Three monthly cycles from now, this fee structure will be the new baseline and sellers will have adjusted to it. The operators who come out of Q2 best are the ones who run the cleanup this week instead of next month. The May 18 statement is a data point. What you do with it is the actual variable. If you’re an FBA seller working through this, I read every email reply, and we cover this kind of stuff in more depth on the YouTube channel. More breaking news coming later today. See you in the next one.
