How to Reduce FBA Storage Fees: 12 Practical Ways

Published: June 24, 2026 | Last updated: June 24, 2026

If you want to know how to reduce FBA storage fees, start with three moves: sell through aging inventory faster, remove or liquidate units before they cross Amazon’s long-age thresholds, and reduce the cubic feet each unit occupies. Those three changes usually produce the fastest savings. In our experience managing Amazon stores, most sellers do not have a traffic problem first. They have an inventory age problem, a replenishment problem, or a packaging problem. This guide shows you exactly how to fix all three.

How Amazon Charges FBA Storage, Quick Primer

What is FBA storage?

FBA storage fees are charges Amazon applies for the space your inventory occupies in fulfillment centers. Amazon measures that space in cubic feet and bills sellers based on product size tier, time of year, and inventory age. Amazon publishes current rules and rates in Seller Central, and those rules can change, so sellers should confirm current numbers before making large inventory decisions (Amazon Seller Central, FBA inventory storage fees).

Monthly storage fees vs long-term storage fees

Monthly storage fees Amazon charges are the recurring baseline cost. These fees usually rise in peak months, especially in Q4, and the rate differs for standard-size and oversize inventory. A slow seller that seems harmless in March can become expensive in October if the same units are still sitting in FBA.

FBA long-term storage fees, also called aged-inventory charges in many seller discussions, apply when inventory remains in Amazon fulfillment centers beyond Amazon’s aging threshold. Amazon has historically assessed special charges on inventory aged 365 days or more, and sellers should review the current aged-inventory policy page for the exact method in force at the time they read this (Amazon Seller Central, Long-term storage fees overview). In practice, the big lesson is simple. Once a unit approaches one year in FBA, the math changes fast.

Here is the fee stack sellers should watch:

Other related charges that increase holding costs

Storage is only part of the bill. Sellers also absorb removal fees, return processing, placement fees, and the margin loss that comes from inventory being stuck instead of sold. We have seen clients focus on monthly storage while ignoring stranded inventory for weeks. That mistake keeps dead stock in the building and lowers the inventory performance index (IPI), which can create more operational pain later.

If you are serious about how to avoid Amazon storage fees, do not isolate the storage line item. Look at total holding cost per SKU.

Quick wins: 8 fast actions to reduce storage costs this month

The fastest way to reduce FBA storage fees is to attack aged inventory by SKU, not by brand-wide averages. A seller with 500 active SKUs usually finds that 10 to 15 percent of the catalog creates most of the storage problem.

1. Run an inventory age audit and prioritize 365+ day SKUs

1. Open Seller Central and pull the Inventory Age report.
2. Sort units into age buckets: 0-90, 91-180, 181-270, 271-365, and 365+ days.
3. Highlight every SKU with more than 90 days of cover and weak sell-through.
4. Create a red-flag list for units at 300+ days.
5. Check stranded, reserved, and unfulfillable quantities before deciding anything.

In our agency work, the 300-day marker is where conversations should change from “wait and see” to “make a decision this week.”

2. Create a bulk FBA removal order for obvious losers

A FBA removal order makes sense when a SKU has low conversion, low margin, and no obvious seasonal rebound. Return the inventory if you can resell elsewhere. Dispose of inventory if the recovery value is close to zero. Waiting another quarter rarely improves the outcome.

3. Compare removal, disposal, and liquidation before acting

Rule of thumb: if projected three-month holding cost is higher than removal plus downstream warehousing, remove it. If recovery from resale is low but not zero, compare liquidation against return. If both numbers look bad, disposal may still be the least expensive option.

4. Run promotions to improve sell-through

Coupons, limited-time discounts, and multi-buy offers can push old inventory out before long-age fees hit. Keep the math tight. For example, if a unit brings $8 net contribution today but will likely cost $1.20 in storage over the next quarter plus a possible aged fee, a discount that reduces contribution to $6 can still be the better financial move.

• Set a floor margin before launching the promotion
• Test one offer for 7 days
• Compare unit session percentage and daily sell-through before and after
• Stop the offer if conversion lift does not offset margin loss

5. Reprice aggressively for aged stock

Many sellers hold stale pricing because they anchored to launch margins. That is expensive. Use repricing rules that trigger harder discounts once inventory reaches 240, 300, and 330 days. Keep a minimum margin safeguard so you do not sell below your true landed-cost threshold.

Example: A SKU has 400 units, $0.18 monthly storage cost per unit, and a 6-unit daily sales pace after a 9 percent price cut. Without the cut, the SKU sells 2 units per day. At the old pace, clearing inventory would take 200 days. At the new pace, clearing inventory takes about 67 days. Even if margin drops by $1.10 per unit, the seller avoids months of storage and aged-inventory exposure.

6. Pause reorders on weak SKUs

This sounds obvious, yet many catalogs keep receiving units because reorder points are too broad. Stop inbound shipments for SKUs with over 120 days of cover unless a verified seasonal event is close.

7. Fix stranded listings

Stranded inventory cannot sell, but it still occupies space. Check stranded reasons weekly. Common causes include listing suppression, pricing errors, and detail page conflicts.

8. Split the catalog into keep, test, and exit groups

That simple classification helps teams move faster. Keep = replenish and protect. Test = run pricing or promotion changes for 14 days. Exit = remove, liquidate, or move off Amazon.

7-day action plan to cut next statement storage fees

• Day 1: Pull Inventory Age, Stranded Inventory, and Excess Inventory reports
• Day 2: Mark 300+ day SKUs and calculate projected 90-day holding cost
• Day 3: Submit removal orders for clear exit SKUs
• Day 4: Launch one promotion set for salvageable aged SKUs
• Day 5: Adjust repricing floors and ceilings
• Day 6: Pause reorders for overstocked items
• Day 7: Review sell-through lift and finalize next wave of actions

Prevent long-term storage fees: inventory policies and automation

If you only react once inventory crosses the danger line, you will keep repeating the same problem. The better system is policy plus automation.

Set automated removal orders and scheduled cleanups

Amazon allows sellers to automate certain aged-inventory actions inside Seller Central. The exact menu structure changes over time, but sellers can usually configure automated removals from FBA inventory settings. A simple rule works well for many catalogs: review at 270 days, action at 300 days, and automatic removal for units that still show weak velocity by 330 days.

We have seen this work especially well for replacement-part catalogs and seasonal accessories. Those categories often have long tails, and human review alone is too slow.

Use the Inventory Performance Index (IPI) to reduce rejections and long aging

What is IPI? Inventory Performance Index (IPI) is Amazon’s score for how efficiently a seller manages FBA inventory. The score reflects sell-through, excess inventory, stranded inventory, and in-stock rates on popular products. A low score does not directly create storage fees, but it usually signals the same bad habits that create high storage costs.

A healthy IPI does not guarantee low storage fees, but weak IPI almost always shows where storage fees come from.

Alerts and saved reports: what to monitor weekly

Use a weekly reporting routine with named owners. The minimum report set should include:

Cut fees by optimizing packaging, sizing and inbound units

One of the most overlooked answers to how to reduce FBA storage fees is physical product design. If you can reduce inches, void fill, or package shape, you may lower cubic-foot usage for every unit stored.

Why dimensions and weight matter

Amazon storage pricing is tied to the amount of space a product consumes. That means a package that is only slightly larger can cost noticeably more over time, especially at scale. Oversize classification can raise both storage and fulfillment expense. Standard-size inventory has lower carrying cost in many cases, so shaving dimensions is often worth testing.

Practical packaging tactics to lower per-unit storage

• Reduce empty space inside cartons by resizing inserts and outer boxes
• Flatten foldable items before send-in
• Use poly bags instead of boxes where Amazon rules allow
• Create intentional bundles when two slow movers sell better together
• Shift from awkward single units to compact multi-packs if demand supports it
• Review labeling and prep methods to avoid unnecessary bulk

Before changing packaging, review Amazon compliance requirements. Our guide to FBA packaging rules and packaging optimization tips covers the operational details sellers usually miss.

When reboxing or creating multi-packs backfires

Not every packaging idea saves money. A smaller box that increases damage rate can raise returns and negative reviews. A multi-pack can also reduce conversion if customers wanted the original single-unit price point. Test with a limited SKU set first.

• Check return reasons before changing packout
• Confirm packaging still protects against inbound and outbound damage
• Verify that labeling, suffocation warnings, and prep rules still apply correctly
• Watch conversion rate for 2 to 4 weeks after a pack change

Decision framework: keep, remove, liquidate, or switch channels (FBM/3PL)

Sellers need a repeatable model, not guesswork. This is where most articles are weak. Here is a practical break-even method you can copy into a spreadsheet.

Decision matrix and break-even calculator

Create these columns for each SKU:

• SKU
• Units on hand
• Average daily sales
• Months to clear = Units on hand / (Average daily sales × 30)
• Monthly storage fee per unit
• Projected holding cost = Units on hand × Monthly storage fee per unit × Months to clear
• Removal cost total
• Liquidation recovery total
• FBM net margin per unit
• FBA net margin per unit
• Recommendation

Rule: if projected holding cost over the expected sell-through period is greater than removal cost plus expected recovery difference, remove the inventory. If FBA margin is worse than FBM after adding storage and aged-risk cost, test FBM.

When switching to FBM or a 3PL makes sense

Many sellers ask whether they should switch FBA to FBM for slow units. Sometimes yes. Here are useful thresholds:

• Expected time to sell exceeds 4 to 6 months at current velocity
• Storage cost plus aged-risk cost exceeds 8 to 12 percent of expected revenue
• SKU is seasonal or long-tail and does not need Prime placement year-round
• You have access to a 3PL with reasonable pick-pack rates

Sample comparison: FBA net margin on a slow-moving home item is $6.20 per unit after monthly storage. FBM net margin is $5.90 after postage and labor, but the seller avoids four more months of storage and possible aged charges. The total profit on the remaining inventory ends up higher under FBM even with a lower per-order margin.

For a broader channel comparison, see our article on deciding between FBA and FBM for storage cost savings.

How to run a limited FBM test without risking the listing

1. Choose 1 to 3 slow SKUs with stable demand but poor FBA economics.
2. Move a small batch to your warehouse or 3PL.
3. List the SKU as FBM while keeping a close eye on shipping settings and handling time.
4. Monitor conversion rate, cancellation rate, late shipment rate, and net margin.
5. Compare 30-day results against the prior FBA period.

Do not move your top ASINs blindly. Use a controlled test.

Programs and services to reduce holding costs (Amazon and third parties)

Amazon gives sellers a few built-in ways to reduce FBA storage fees, and outside partners can help where Amazon is too expensive for long-tail inventory.

Amazon options: liquidation, removal, and promotions

Amazon liquidation can be useful for inventory with some residual value but poor retail demand. Removal works better when another channel can absorb the stock. Promotions and coupons are best when the listing still converts and reviews are healthy. Each tool solves a different problem.

Third-party fulfillment and long-term warehousing

A 3PL often wins when you have long-tail catalog items, multi-channel sales, or seasonal overflow. FBA is excellent for fast movers. It is often expensive for items that need six months to sell through.

Using fulfillment partners for seasonal overflow

• Keep 30 to 45 days of top-seller stock in FBA
• Store reserve inventory at a 3PL
• Replenish FBA more frequently during peak
• Move slow off-season SKUs out of FBA until demand returns

This hybrid model is one of the most reliable answers for sellers trying to avoid long term storage fees without hurting in-stock rates.

Monitoring, reporting and a monthly storage-fee audit routine

Cost control only works if someone owns the process. The monthly audit should be simple enough to complete in under 90 minutes.

Monthly audit checklist

1. Pull Inventory Age, Excess Inventory, Stranded Inventory, and Business Reports.
2. Calculate days of supply and months to clear for each SKU.
3. Score each SKU as Green, Watch, Action, or Exit.
4. Check 270+ and 300+ day inventory separately.
5. Review stranded and unfulfillable units first.
6. Update reorder settings based on recent demand, not old forecasts.
7. Submit removal or liquidation actions for Exit SKUs.

When NOT to aggressively cut storage, tradeoffs and risks

Not every high-storage SKU should be removed. Some inventory earns its keep even while it sits.

Brand, launch seasons and stockout risk

Seasonal SKUs, hero products before Prime events, and launch-support inventory may justify higher storage. A stockout on a top ASIN can cost ranking, ad efficiency, and market share. We have seen sellers save a few hundred dollars in storage and lose several thousand in contribution margin from a mistimed cleanup.

Costs of returns, relisting, and lost Buy Box potential

• Removal and relabeling can create extra labor cost
• Re-sending inventory back into FBA can add inbound and prep expense
• FBM conversion may drop if the listing relies heavily on Prime demand
• Catalog availability gaps can hurt Buy Box share

The right question is not “Can I reduce FBA storage fees?” The right question is “Does reducing this fee improve total profit?” On top sellers, the answer is sometimes no.

FAQ, sellers’ top questions about FBA storage fees

What counts as long-term storage for FBA and when are fees charged?

Long-term storage for FBA usually refers to inventory that has been stored in Amazon fulfillment centers for 365 days or more. Amazon’s exact billing method and timing can change, so sellers should confirm the current policy in Seller Central. A seller should start reviewing units around 270 to 300 days, because that gives enough time to discount, remove, or liquidate inventory before aged-inventory charges become expensive.

How are FBA storage fees calculated each month?

FBA storage fees are calculated based on the cubic feet your inventory occupies, the product’s size tier, and the time of year. Standard-size and oversize products have different rates, and peak-season months are often more expensive. To estimate a monthly charge, multiply units on hand by cubic feet per unit and then apply the current Amazon storage rate for that inventory class (Amazon Seller Central, 2026).

Can I avoid quarterly long-term storage fees with automated removals?

Yes, automated removals can help you avoid long term storage fees if the rules trigger early enough. A seller should not wait until inventory is already at the aged threshold. Set review points around 270 or 300 days, and make sure the system excludes seasonal winners that are still profitable to keep. Automation is most effective when paired with a weekly inventory age review.

Is it cheaper to switch slow SKUs to FBM or use a 3PL to avoid storage fees?

It can be cheaper to switch slow SKUs to FBM or move them to a 3PL when the expected sell-through window is long and monthly FBA storage keeps stacking up. The best choice depends on shipping cost, conversion impact, and how much Prime eligibility matters for the ASIN. A seller should compare total projected FBA holding cost against 3PL storage plus pick-pack and shipping. For long-tail inventory, the off-Amazon option often wins.

How do I calculate whether removal or liquidation is the better option?

Compare four numbers: projected holding cost if you keep the inventory in FBA, total removal cost, expected recovery from liquidation, and expected recovery from selling elsewhere after removal. If projected holding cost is higher than removal cost and resale recovery is still reasonable, removal is often the better option. If outside resale is weak but liquidation pays something, liquidation may be the simpler choice.

Can Amazon refund storage fees if inventory was misclassified or stranded?

Amazon may issue fee adjustments in some cases if inventory was measured incorrectly, misclassified, or affected by a system issue, but sellers need documentation. A seller should review product measurements, fee previews, stranded inventory history, and case logs before filing a claim. Refunds are not automatic, so the seller must present a clear reason and supporting data through Seller Central.

How does Inventory Performance Index (IPI) affect my storage costs?

Inventory Performance Index does not directly replace storage fees, but IPI strongly affects how efficiently a seller manages FBA inventory. A low IPI usually means too much excess inventory, too many stranded units, or poor sell-through. Those same conditions increase monthly storage fees and raise the chance of aged-inventory charges. Improving IPI helps reduce recurring storage waste over time.
