Are the rates current?

The default is a typical value and is editable — Amazon rates change seasonally, so we ask you to verify the current rate in Seller Central. We never show invented data.

How do I calculate for Q4?

Just enter the Oct–Dec rate (typically ~$2.40/ft³) in the rate field.

The problem

Storage fees quietly eat your margin.

Rates roughly triple in Q4; sellers who don't plan for it lose money.

📦

Volume blindness

You can't estimate fees without knowing your cubic feet.

🎄

Q4 surprise

Oct–Dec rates are much higher; plan inventory accordingly.
