Amazon Aged Inventory Surcharge (2026): The 271-Day Cliff and When to Clear Stock

The Amazon aged inventory surcharge is a monthly charge on FBA units that have sat in the fulfillment network longer than 180 days, billed per cubic foot on top of your regular monthly storage fee. Amazon’s rate card, effective January 16, 2026, runs from $0.50 per cubic foot at 181–210 days to $7.90 per cubic foot or $0.35 per unit, whichever is greater, at 456 days and over (Amazon staff account Angie_Amazon, Seller Forums, data checked 2026-07-31).

The number that should drive your decisions is not 181. It is 271 — the band where the rate jumps from $1.50 to $5.45 per cubic foot, a 3.6× step in one month. This guide covers the actions that stay in front of that step: a decision rule for keep vs. discount vs. remove, and a monthly cadence keyed to Amazon’s cleanup deadline.

Fact Block: The Official Aged Inventory Surcharge Rate Card

The Seller Central help pages holding the canonical schedule sit behind a login — we confirmed on 2026-07-31 that the Aged inventory surcharge help page returns a sign-in wall to a logged-out reader. Every figure below comes from pages readable without an account: Amazon staff posts on the public Seller Forums, and Amazon’s own announcements.

Rate card as posted by Angie_Amazon in AVOID Costly Fees: Aging Inventory Action Plan, Seller Forums, read logged out; the post states the schedule applies “Starting January 16, 2026.” Data checked 2026-07-31. Confirm against your own fee schedule before a large removal — Amazon has revised these bands more than once.

Four mechanics matter more than the numbers:

• It is billed on volume, not units — until it isn’t. Amazon staff on the forums: “Typically, aged inventory surcharges are calculated per cubic feet” (Jameson_Amazon, Aged Inventory Surcharge PER UNIT or OVERALL, checked 2026-07-31). The two oldest bands add a per-unit floor that bites when a unit is small. Our arithmetic on Amazon’s published rates puts the crossover at $0.30 ÷ $6.90 ≈ 0.043 cubic feet (366–455) and $0.35 ÷ $7.90 ≈ 0.044 cubic feet (456+) — roughly 75 cubic inches. Below that you pay per unit, so tiny, cheap, dead SKUs get disproportionately expensive to keep.
• The clock is FIFO across the whole network. Per TaylorR_Amazon: “inventory age is calculated on a first-in, first-out basis across the entire fulfillment network. Items that are sold or removed are deducted from the inventory that has been in the fulfillment network the longest, regardless of which unit was actually shipped or removed” (Confusion about Aging Inventory, checked 2026-07-31). Every sale burns down your oldest units first, so a SKU with steady velocity ages far more slowly than its unit count suggests.
• It stacks, and it recurs. Amazon’s post: these surcharges “are assessed monthly on the 15th of each month and charged between the 18th–22nd, in addition to your regular monthly storage fees.” It is added to the monthly storage fee, not charged instead of it, every month the units stay.
• Some categories are exempt. When Amazon introduced surcharges on the 180–270 day range (effective April 15, 2023), it did so “excluding products in the following categories: Apparel, Shoes, Bags, Jewelry, and Watches” (An update to our US referral and FBA fees, checked 2026-07-31).

The Framework: Three Zones, Not Eight Bands

Eight bands is a table. Three zones is a decision.

Zone 1 — Warning (181–270 days): about $3.00 per cubic foot in total ($0.50 + $1.00 + $1.50). On a unit occupying 0.1 cubic feet, roughly 30 cents across three months — not a reason to dump stock at a loss. Its only job is to make you decide before Zone 2.

Zone 2 — Expensive (271–365 days): about $17.05 per cubic foot ($5.45 + $5.70 + $5.90). The rate barely rises inside the zone; the damage was the one-time step at day 271.

Zone 3 — Punitive and open-ended (366+ days): about $20.70 per cubic foot across the 366–455 band, then $7.90 per cubic foot every month, indefinitely. No band caps out.

These totals are our arithmetic on Amazon’s published rate card, not figures Amazon publishes. They assume one monthly assessment per ~30-day band, which is what the 15th-of-the-month cadence produces; your count can differ by one depending on where a unit’s receive date falls. Use them to rank decisions, not to book accruals.

The priority follows directly: 85% of the cost of holding a unit from 181 to 365 days lands after day 270. A unit at day 250 is a cheap problem; the same unit at day 280 costs more in one month than in its entire first nine months of aging.

The Gate: Keep, Discount, Remove, or Dispose

Work the gates in order, per SKU, on the aged tail only.

Gate 1 — Is the SKU exempt, and through which bands? Amazon introduced the exclusion for Apparel, Shoes, Bags, Jewelry, and Watches together with the 180–270 day range, so those three bands are clear. It does not restate the exclusion for the 271+ bands, where the forum rate card carries it only as an unqualified footnote under the whole table — nothing readable logged out settles whether the exemption survives day 271. If you sell these categories, confirm in your own Fee Preview before assuming the day-271 step will not reach you. Either way, aging costs monthly storage and drags the excess-inventory component of your IPI score.

Gate 2 — Will FIFO clear the tail before day 271? Divide the oldest units — not total on-hand — by trailing 30-day units sold. If the tail clears before day 271, keep selling; there is no decision. This is where most panic removals are wasted.

Gate 3 — Can a discount clear it before the cliff? Amazon’s own suggestion: “Create promotional offers with a minimum 20% discount to help move older inventory quickly. Outlet deals can help you boost sales, improve cash flow, and reduce storage fees — with no additional fees to participate” (Angie_Amazon, checked 2026-07-31). The test is arithmetic: discount if the margin left after a markdown that actually clears the tail exceeds the surcharge and storage you avoid. For a 0.1 cubic-foot unit, Zone 2 costs about $0.55 per unit per month in surcharge alone — so on a $25 item a 20% cut ($5) must buy far more than one avoided month. Check the trailing price band with a price-history tool before cutting deep enough to reset your own reference price.

Gate 4 — Is the unit worth more outside FBA than the cost of holding it in? Then remove it. Removal and disposal fees are per-unit by size tier and live in your fee schedule; the only 2026 change was billing timing. Per News_Amazon: “Effective March 1 [2026], Fulfillment by Amazon (FBA) removal and disposal fees will be charged on a per-unit basis at the time each unit is removed or disposed of,” and “This is a charge timeline change only. The fee rates for removal and disposal fees remain unchanged” (announcement, checked 2026-07-31). Removals are also where shortfalls appear: units lost or damaged in transit are a common reimbursement case, and audit tools such as ReimburseOps check an exported FBA reimbursements report against your own sourcing costs to flag under-reimbursed and inconsistently valued records (checked 2026-07-31).

Gate 5 — Is recoverable value below removal cost? Dispose or liquidate. Disposal ends the surcharge; liquidation returns a fraction of value without a return shipment. Neither is a good outcome; both beat $7.90 per cubic foot per month forever.

When a gate is ambiguous, default to Gate 4, not Gate 2. Holding is the option that compounds: a wrong removal costs one removal fee, a wrong hold costs the Zone 2 step and every month after it.

Checklist: The Monthly Early-Clear Cadence

Amazon assesses on the 15th, and its stated deadline for acting is the day before. Angie_Amazon’s instruction is exact: “Submit a removal or disposal order before the cleanup date (deadline: 11:59 PM PT on the 14th of each month).” Whether units in a submitted-but-unprocessed order are excluded from that month’s assessment is documented only on the login-walled help page, so treat the 14th as a hard submit-by date and do not cut it fine.

1. Days 1–5 — Pull the age report and sort the 241–270 bucket first, then 211–240, then 181–210. Jim_Amazon, replying in a News_Amazon thread after the original link broke, places Amazon’s aging analytics page under Inventory → Analytics (thread, checked 2026-07-31), though that post is roughly two years old — confirm the menu path in your own account. Ignore the 366+ tail on this pass; its rate barely moves. Your leverage is entirely in front of day 271.
2. Days 5–8 — Run Gate 2 on each aged SKU (aged units ÷ trailing 30-day velocity) and clear stranded units in the same pass. A unit without an active offer cannot sell, so its age can only rise — the one aged-inventory problem a relist fixes for free.
3. Days 8–12 — Set Gate 3 discounts at 20% or more, with a full month of runway. A markdown launched on the 13th clears nothing by the 15th.
4. By the 13th — Submit removal, disposal, or liquidation orders for everything that failed Gates 2 and 3. One day of buffer, not zero.
5. Same day — Freeze inbound on every SKU in the report. Sending more units does not dilute the average; under FIFO the old units age on regardless while the new ones start their own clock. Fixing that permanently is a reorder-timing problem — restock forecasting software is the category, and a neutral, workflow-organised directory of options is maintained at AMZFinder’s inventory and operations workflow page.
6. Once a quarter — Enable automated removals as a backstop. Amazon’s settings can automatically remove fulfillable inventory stored more than 365 days, or units of ASINs unsold for six or more consecutive months that have been in fulfillment centers more than 180 days (Angie_Amazon, checked 2026-07-31). A backstop is not a strategy — anything it catches is already deep in Zone 2 — but it stops indefinite accrual on SKUs you forgot.

Timing note for Q3: units received during last year’s peak are crossing into Zone 2 now, with Q4 storage rates and the October peak surcharge landing on top — see the Q4 readiness checklist for the seasonal side. September is the most expensive month to still be deciding.

Common Mistakes

• Treating day 181 as the deadline. It is the notification. The deadline is day 271, where 85% of the cost lives.
• Removing the whole SKU instead of the tail. FIFO retires your oldest units as you sell. Remove the quantity that will not clear before the next band.
• Assuming per-unit pricing. The surcharge is volume-based through day 365, so a bulky low-value SKU is worse than its unit count implies — check your FBA size tier mix.
• Sending replenishment into an aged SKU to “average down.” There is no averaging — both cohorts age separately and you have added cubic feet to a losing position.
• Quoting an undated rate table. Third-party pages still circulate pre-2026 bands, including a $0.15 per-unit figure the current card replaced. Any table without a date and an Amazon source is a historical artefact.

Frequently Asked Questions

What is the Amazon aged inventory surcharge in 2026?

A monthly charge on FBA inventory stored longer than 180 days, billed per cubic foot on top of your monthly storage fee. Per Amazon’s Seller Forums staff post, the schedule starting January 16, 2026 runs from $0.50 per cubic foot at 181–210 days to $7.90 per cubic foot, or $0.35 per unit if greater, at 456 days and over (checked 2026-07-31). Apparel, shoes, bags, jewelry, and watches are excluded from the 181–270 day bands; Amazon does not restate that exclusion for the 271+ bands, so sellers in those categories should confirm in their own Fee Preview.

When exactly is the surcharge charged?

Amazon’s post states the surcharges “are assessed monthly on the 15th of each month and charged between the 18th–22nd, in addition to your regular monthly storage fees,” and that removal or disposal orders should be submitted “before the cleanup date (deadline: 11:59 PM PT on the 14th of each month)” (checked 2026-07-31).

Is the aged inventory surcharge the same as the long-term storage fee?

It is the successor to it. “Long-term storage fee” was the older name for the charge on inventory held past a long threshold; the current structure is a graduated surcharge starting at 181 days that sits on top of the monthly storage fee.

Does selling units reset my inventory age?

No, but it consumes it. Amazon calculates age first-in, first-out across the whole network: units sold or removed are deducted from the oldest stock on hand, whichever physical unit shipped. So velocity — not total quantity — decides whether a tail is a problem.

Should I remove inventory or discount it?

Compare what you keep against what you avoid: if the margin left after a markdown that actually clears the tail exceeds the surcharge and storage you would otherwise pay, discount; if not, remove. The comparison changes sharply at day 271, where avoided cost jumps 3.6× while your margin does not.

Does the aged inventory surcharge affect my IPI score?

Not as a fee, but the same inventory does: Amazon lists avoiding “excess and aged inventory, and long-term storage costs” among the behaviours the Inventory Performance Index rewards (FBA inventory management, checked 2026-07-31). Aged stock costs twice — the surcharge, and the capacity headroom a lower score takes away.

Conclusion

The aged inventory surcharge is less a fee to understand than a date to beat: roughly $3.00 per cubic foot across the whole 181-to-270-day stretch, roughly $17.05 across the next ninety-five days. Pull the age report on the 1st, sort the 241–270 bucket first, divide the tail by velocity, discount only what a markdown can actually clear, submit removals by the 13th, and freeze inbound on anything carrying an aged cohort.
