Amazon Storage Fee Calculator
Cubic feet, and the peak season multiplier.
Amazon revises fee schedules at least annually and adds new surcharges more often. These defaults are a starting point — the figures in your own fee preview are the ones that describe your ASINs.
Monthly storage
$117
150.0 cubic feet at $0.78 each
Peak storage costs $360 a month against $117 off-peak — roughly 3.1 times as much. Holding fourth-quarter stock at Amazon from August is expensive; holding it at a third-party warehouse and topping up weekly usually is not.
How the Amazon Storage Fee Calculator works
Storage is charged per cubic foot per month, and the fourth-quarter rate is roughly three times the rest of the year. Sellers who send Christmas stock in August pay peak rates on it for months before it sells.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
How is FBA storage charged?
Per cubic foot of the daily average volume you hold, billed monthly. Rates differ by size tier and roughly triple from October to December.
How do I calculate my cubic feet?
Length times width times height in inches, divided by 1,728, times the number of units. Use packaged dimensions — Amazon measures the unit as it arrives, not the bare product.
How do I reduce storage costs?
Send less, more often. Holding buffer stock at a third-party warehouse and replenishing weekly costs less than peak FBA rates, especially in the fourth quarter, and it avoids the ageing surcharges entirely.
What counts as peak season?
October through December. The rate change applies to the whole quarter, so inventory that arrives in September and sells in January pays peak rates for three months without ever benefiting from the peak demand.
