EP426: Amazon FBA Storage Fees: The Q4 Bill That Eats Your Margin

Hook title

Amazon's Q4 storage rate already kicked in. It went live on October 1st, and if you missed it, it has been running on your inventory ever since. I'll close with The Voltage 3, today's challenge: three checks you can run in your own account before the next episode.

The Math Behind the Spike

But before we get to today's Voltage 3, we need to talk about the Q4 bill. It is the number that actually eats your margin. Amazon's own rate table shows the trap. From January through September, standard size storage ran at seventy-eight cents per cubic foot. That is a manageable rate. Then, on October 1st, that rate jumped to two dollars and forty cents per cubic foot. Oversize went from fifty-six cents to a dollar forty. It is not a small bump. It is a massive shift in your monthly cash flow. And it already happened. If you missed it, every cubic foot you have had sitting in Amazon since October 1st is running at the higher rate. Then a second fee landed on October 15th. That is the holiday peak fulfillment fee, and it runs through January 14th, 2027. Do not mix those two up. Storage is what you pay for the shelf. The peak fulfillment fee is on the orders Amazon fulfills for you. Both are live on your account right now. For those of you running multiple SKUs, the math gets ugly fast. If you are holding excess stock that does not move during the peak, you are now paying more than double what you paid in September. That is a direct hit to your margins. You see the problem, right? Most operators treat storage as a fixed cost. It is not. It is a variable cost that grows with every day your stock sits. Every cubic foot you store in Q4 has to earn its spot. If it does not, you are funding a dead asset. We have more than twenty-five brands of our own. Run this math on every SKU before you place a purchase order. If the peak season cost does not justify the unit, skip the order. Some sellers figure they will deal with it after the holidays. They cannot wait. Amazon charges storage monthly based on your daily average volume. Every day your slow stock sits there between now and the end of December, it adds to that bill at the peak rate. The peak season already started, so the exit plan starts today. That means looking at your inventory aging and cutting the slow movers now. Not later. Now. If you want to break down the specific mechanics of how Amazon calculates this daily average, go listen to episode four hundred twenty to dig into that further. It breaks down the preview numbers that tell you what your January bill is going to look like. For now, focus on the current cost. Cut what does not move. Protect what does.

The Inventory Trap

Here is how the math works in your own account. Say you have two products. One is your hero. It sells every day. The other one barely moves. It has good reviews, but it does not sell fast enough, and it is still taking up space in an Amazon fulfillment center. Back in September, that space cost seventy-eight cents per cubic foot for standard size. Since October 1st, the same space costs two dollars and forty cents per cubic foot. Same product. Same shelf. More than double the bill. And Amazon charges storage monthly based on your daily average volume, so every day that slow product sits there, it adds to the bill. Now put that next to what the product actually sells. If the storage cost is bigger than what it brings in, it is not an asset. It is a liability. And in the peak season, that liability grows. So here is the move. Pull the daily sales for every product in your account. Not just the big ones. Look at the slow ones. The ones sitting there because you were afraid to let them go. If a product does not cover its storage cost, stop buying it, clear the old stock, and put that space on the winners. This is not about being perfect. It is about being honest. The peak rates are already running. So act now. Not in January. Now.

The Voltage 3

Alright. Here is The Voltage 3. Number one: Calculate your cubic feet for slow-moving SKUs using Amazon's storage rates. That is seventy-eight cents per cubic foot for January through September, and two dollars and forty cents for October through December, standard size. Compare the October to December cost against the January to September cost. Check: Have you identified which SKUs cost more than double to store in Q4 compared to Q3? Number two: Audit your inventory aging. Identify stock that has been in the system long enough to trigger higher costs or risk obsolescence. Check: Do you have a list of items that are not moving fast enough to justify the $2.40 per cubic foot standard rate? Number three: Review your daily average volume. Ensure you are not holding excess stock that drives up the monthly charge. Check: Have you reduced the daily average volume for non-peak items to lower the monthly storage bill? Complete all three before the next daily episode.
