How to reduce your Amazon FBA storage fees

FBA storage fees, aged-inventory surcharges and low-inventory fees add up fast. Here is how sellers cut them without running out of stock.

Why FBA storage gets expensive

Amazon charges monthly storage by volume, and it charges aged-inventory surcharges that climb steeply the longer stock sits, especially past 180 and 365 days. Overstock at FBA is one of the most common hidden costs for sellers.

The core tactic: buffer storage upstream

Instead of sending months of inventory into FBA, keep the bulk in cheaper buffer storage and send smaller, frequent replenishments to Amazon. You pay a low upstream storage rate and only put what you need into the expensive FBA bins.

  • Store bulk inventory at a 3PL at roughly $0.50/cu.ft
  • Replenish FBA in smaller, more frequent shipments
  • Avoid aged-inventory surcharges by never overstocking FBA
  • Balance against low-inventory fees by keeping enough in the pipeline

Other ways to cut fees

Beyond buffer storage:

  • Liquidate or remove dead stock before it crosses aging thresholds
  • Resell returns instead of leaving them in FBA limbo
  • Bundle slow movers to increase sell-through
  • Watch your IPI score to avoid storage limits

Common questions

FAQs

What is the aged-inventory surcharge?+

An extra monthly fee Amazon charges on inventory that has been in FBA a long time, increasing at thresholds like 180+ and 365+ days. Buffer storage upstream is the main way to avoid it.

Will buffer storage cause stockouts?+

Not if replenishment is timed well. The goal is smaller, more frequent FBA shipments, balanced against Amazon low-inventory fees.

Keep FBA lean, keep more margin.
