Amazon Storage Fees in 2027: Rates, Aged Inventory and How to Cut Them

Amazon storage fees are the part of the FBA bill sellers have the most control over, and the part most often ignored until Q4. Monthly storage, the aged inventory surcharge, the storage utilization surcharge and low inventory fees all depend on how much stock you hold and how fast it sells. This guide covers how each storage charge works, the rates widely published for 2026, what to expect going into 2027, and the simple habits that keep storage costs from eating margin. Confirm every number in Seller Central before you commit to a replenishment plan, since Amazon updates schedules and some third party sources disagree on small details.

How Amazon calculates monthly storage fees

Monthly inventory storage fees are charged per cubic foot, based on the average daily volume your inventory occupies in fulfillment centers. Size tier matters: standard size and oversize have different rates, and dangerous goods use higher ones. The rate also depends on the season, with a higher rate from October through December.

Rates published across several 2026 fee guides:

Item type	January to September	October to December
Standard size	$0.78 per cubic foot	$2.40 per cubic foot
Oversize	$0.56 per cubic foot	$1.40 per cubic foot

One caution: at least one source lists a higher $0.87 off peak standard size rate from July 2026, while others dispute that. Check the fee schedule in Seller Central for the rate that applies to your account and month.

Because charges use average daily volume, cutting units in the last week of a month does not erase earlier days. Volume is smoothed, so plan sell through weeks ahead.

Why Q4 is the danger zone

The October to December rate is roughly three times the off peak standard rate. A pallet that costs little in August costs far more in November. The replenishment decisions you make in August and September effectively set your Q4 storage bill, so cap inbound quantities for slow SKUs before peak.

Aged inventory surcharge

Inventory that sits in fulfillment centers for a long time gets an extra monthly charge on top of regular storage. The surcharge starts at 181 days in a fulfillment center. A published 2026 schedule from SellerSprite lists these per cubic foot charges:

Days in FBA	Surcharge per cubic foot
181 to 210	$0.50
211 to 240	$1.00
241 to 270	$1.50
271 to 300	$5.45
301 to 330	$5.70
331 to 365	$5.90
366 to 455	$6.90, with a $0.30 per unit minimum
456 and over	$7.90, with a $0.35 per unit minimum

The early tiers exclude clothing, shoes, bags, jewelry and watches according to that source, and some categories may be exempt from other bands. The jump at 271 days is the one to fear: the surcharge rises more than threefold in a single step. Use the Manage Aged Inventory view in Seller Central, and act before units hit 240 days.

Storage utilization surcharge

This charge targets sellers who hold a lot more inventory than they sell. It is based on your storage utilization ratio, which is roughly the weeks of cover you carry. Published guides describe it as applying above about 22 weeks of supply for standard size, with a rate that climbs toward $1.88 per cubic foot at 52 weeks or more, and only for stock held beyond 30 days. Amazon can change thresholds, so check the current rule.

Low inventory level fee

The opposite problem also costs money. If an FNSKU has fewer than roughly 28 to 35 days of supply (sources differ on the exact threshold), a per unit low inventory level fee applies. Amazon measures it per FNSKU rather than across your whole account, and grocery is exempt. The per unit amount depends on days of cover and size tier, so check the current schedule in Seller Central. The fix is the same as for stockouts: keep a replenishment buffer. Our best Amazon seller tools roundup covers forecasting tools that flag low cover early.

Removal and disposal fees

If you decide a unit is not worth storing, you can remove or dispose of it. Fees are charged per unit as processed, and rates vary by size and by removal type, so check the current schedule in Seller Central. Compare that against another month or two of aged charges. Often removal in the 200 day range is cheaper than waiting.

A storage playbook for 2027

1. Set a days of cover target per SKU. Between roughly 35 and 60 days is a common planning band, adjusted for lead time and seasonality.
2. Review aged inventory every month. Flag anything past 150 days and decide: discount, bundle, advertise, remove.
3. Time inbound shipments to the calendar. Land stock for peak in September, not in the weeks that run into the higher rate. Use the Amazon sales calendar to line up events.
4. Right size cartons and packaging. Smaller cubic volume lowers storage cost and sometimes drops a size tier.
5. Use Amazon's Capacity Manager and storage limits to understand how much space you actually have before you ship.
6. Improve conversion on slow SKUs. Better content moves stock faster, and a sharper listing from an optimization workflow often costs less than the aged fee it avoids.

What to expect for 2027

Amazon has historically announced fee updates in the fall for the following year, with at least 90 days notice before increases. Rates for storage have changed more than once in recent years, including thresholds for aged inventory, so assume more movement. Build a buffer of five to ten percent into your storage cost assumptions and revisit them when the 2027 schedule is posted.

The GTM angle

Storage pain is concrete, measurable and seasonal, which makes it ideal for outbound. Sellers with aged stock know it, and they are actively looking for a solution in Q3 before the peak rate begins.

If you are an agency, liquidation partner, 3PL, prep center, forecasting tool or ads provider, use it like this:

• Segment by inventory profile. Slow moving, high cubic volume sellers (furniture, home, bulky goods) feel storage most. Lead with removal, liquidation and prep storage alternatives. Fast moving brands care about avoiding low inventory fees, so lead with replenishment forecasting.
• Trigger on timing. Send in July and August ahead of Q4 rates, and again when sellers review their aged inventory report around the 180 day mark.
• Lead with a diagnostic offer. "Send us your Manage Aged Inventory export and we will show what you will owe by December" is a stronger first touch than a feature list.
• Quantify the payoff. One calculated line, such as projected storage and aged fees avoided, carries a cold email further than adjectives.

Frequently Asked Questions

How much are Amazon FBA storage fees per cubic foot?

Widely published 2026 figures are $0.78 per cubic foot for standard size and $0.56 for oversize from January to September, rising to $2.40 and $1.40 from October to December. Verify in Seller Central.

When does the aged inventory surcharge start?

At 181 days in a fulfillment center, with charges rising in steps and jumping sharply after 270 days.

What is the storage utilization surcharge?

An extra fee for sellers whose inventory far exceeds their sales, measured in weeks of cover. Published guides cite a threshold of about 22 weeks of supply for standard size items.

How can I reduce storage fees?

Limit inbound quantities on slow SKUs, run promotions before 180 days, remove or dispose of stale units, and ship smaller cartons.

Do storage fees go up in Q4?

Yes. The monthly rate for standard size inventory is higher from October through December, so inventory on hand in those months costs significantly more.

Takeaways

• Storage is billed per cubic foot on average daily volume, with a much higher rate in October to December.
• The aged inventory surcharge begins at 181 days and spikes after 270 days.
• Too much stock triggers utilization surcharges, and too little triggers low inventory fees.
• Review aged stock monthly and remove or discount before the big steps.
• Storage deadlines are natural triggers for outbound to Amazon sellers.
