Amazon FBA storage fee calculator
Nearly every storage calculator you will find quotes US dollars per cubic foot and starts the long-term clock at 181 days. Both are wrong if you sell on Amazon UK.
This one uses Amazon's actual UK rate card: pounds per cubic foot, the real Q4 uplift, and the 241 day aged inventory surcharge UK sellers are billed under. Add every product in your shipment, because they all sell at different rates.
What will this shipment cost you to store?
Storage is charged on the space your stock occupies, every month it sits there. Slow stock pays rent twice: once in tied-up capital, once to Amazon.
October to December costs roughly double, and the clock keeps running after that. Switching this from July to October is usually the biggest single change to the number below.

All figures are £ per cubic foot per month from Amazon's European FBA rate card, effective 1 February 2026. Amazon changes these, so check Seller Central before making a decision that hangs on them.
Not included: the storage utilisation surcharge, which only applies once your stored volume exceeds 22 weeks of shipped volume. It does not apply to new sellers in their first 52 weeks, Individual accounts, or anyone storing under 25 cubic feet a day, so most people reading this are exempt.
The cheapest storage is stock that is already sold
Sending little and often beats one big shipment sitting through Q4. Our prep centre turns stock around in 24 to 48 hours, from 35p a unit.
