Q4 storage rates (Oct–Dec) are typically much higher — split your calculation by month for accuracy.

Slow SKUs above the long-term threshold hit hardest — clear them with a promo or removal order.

Method

Monthly storage cost = Cubic feet × Monthly rate. Long-term surcharge applies to inventory older than the threshold you enter.

Frequently asked questions

Are FBA storage rates the same all year?

No. Standard-size rates rise sharply in Oct–Dec, and oversize rates differ. Always pull the current table from Seller Central.

How do I lower FBA storage costs?

Shrink case pack sizes, remove aged inventory, and use FBA new-selection or off-Amazon channels for slow movers.
