How To Figure Amazon Monthly And Long Term Storage Fees

The process of figuring Amazon storage fees is quite simple and only requires some basic math and dimensional information supplied on Amazon product pages.

I will show how to figure it and then show some tools to make it easier.

Cubic Dimensions

Amazon charges storage fees based on a rate per cubic foot.  A cubic foot is 1728 cubic inches ( 12” x 12” x 12”) .  I put this in inches because the dimensions listed on Amazon product pages are in inches and generally we are dealing with less than a cubic foot on most products.

If you scroll down to the Amazon product page, you can find the product dimensions in the product details section.

In this case, the dimensions are 10” x 9.7” x 10”

To calculate the cubic foot, you take base x width x height ( in inches) and divide that by 1728.

So in this case, we take 10 x 9.7 x 10 and divide that by 1728.

970/1728 = .56 cubic foot

Amazon Storage Fees

After we had the cubic dimension, we simple take that times the rate per cubic foot that Amazon is charging for storage.

There are a few different rates that you will be looking at.  There is the monthly storage fee for both standard and oversize and there is a normal monthly rate and a Q4 storage rate for each of the size categories.

We also can use this to figure long term storage fees ( LTSF).  We simply use the same cubic dimension and either the 6 month storage fee rate or the 12 month storage fee rate.

Tools

Amazon actually has a webpage that has a calculator for this

The issue with this is that you have to search the Amazon product page for the dimensions and then  manually enter them into the Amazon fee calculator page

My developed a Chrome extension that automatically does this at a click of a button.

I have it up on the Chrome Store for a monthly fee

I also have it up on Gumroad for a one time fee
