Storage fees quietly distort landed cost: the same SKU costs more per unit the longer it sits. Handling warehousing honestly in your cost model changes which products and reorder sizes actually make money.

## The fee your margin report never shows

Most landed cost models stop at the warehouse door: product, freight, duty, insurance. Then the goods sit, and the 3PL meter starts running: receiving, putaway, monthly storage by pallet or cubic foot, pick fees, and account charges. Those costs land in a general operations line, spread evenly, which means fast movers subsidize slow ones on paper.

The distortion changes decisions. A product that looks healthy on a door only cost can be a quiet loser once its storage reality is priced in: bulky, seasonal, or slow turning stock occupies expensive space for months. Pricing, reorder, and clearance decisions made on the flattering number repeat the mistake every cycle.

## Allocate storage by space and time, not by sales

The honest method is unglamorous: for each SKU, track units received, average units held, the cubic volume per unit, and months in storage. Multiply volume by your 3PL storage rate and divide by units sold in the period, and each SKU carries the rent for the shelf it actually used.

Perfection is not required. Even a quarterly allocation using average inventory snapshots beats the standard practice of ignoring storage entirely. The goal is ranking truth: which SKUs cover their full cost of sitting still, and which only look profitable because their rent is being charged to everyone else.

## Inbound and handling belong in the same picture

Receiving and putaway fees scale with shipments and units, so fold them into landed cost per unit at receipt, the same as freight. Pick and pack is usually treated as a fulfillment cost per order rather than landed cost, and that split is fine, as long as it is consistent and someone owns the full stack when a product's economics are judged.

Watch for the fee schedule's quiet clauses: minimum storage charges, long term storage surcharges after set periods, and pallet versus bin pricing tiers. A reorder decision that pushes a SKU into a long term surcharge bracket can erase the quantity discount that justified the bigger order.

## Let storage truth drive inventory decisions

Once storage is priced per SKU, several decisions sharpen at once. Order quantities shrink for bulky slow movers. Seasonal buys get honest deadlines, with clearance triggered when projected storage exceeds the margin at stake. Assortment reviews finally compare products on the cost of the space they consume, not just the margin on the units that sold.

Share the numbers with whoever buys inventory. Purchasing teams rewarded on unit cost will keep ordering deep and cheap until storage appears in the same report as their discount. One page showing discount earned minus storage paid ends that argument faster than any policy memo.

## Build it into the monthly close

Add a storage allocation step to the monthly landed cost refresh: pull 3PL invoices, map charges to SKUs with your space and time method, and publish margins both ways for a quarter so the business can see the shift before it becomes the official number. Surprises handled gradually become process. Surprises dropped in one month become disputes.

Revisit the method when your 3PL contract changes. New rates, new storage tiers, or a move from pallet to cubic foot billing all change the allocation math. Landed cost is a living model of how your supply chain actually charges you, and storage is the line that proves it.

## Frequently asked questions

## Is warehousing part of landed cost or a separate expense?

Both views exist, but for product decisions it belongs in the per unit picture. Storage varies by SKU, space, and time, so spreading it as general overhead hides which products actually cover their costs.

## How do you allocate storage fees to individual SKUs?

Use the space each unit occupies and how long units sit: average inventory times cubic volume times the 3PL storage rate, divided by units sold in the period. Quarterly snapshots are accurate enough to rank products honestly.

## Which storage fees surprise brands most?

Long term storage surcharges, minimum monthly charges, and the jump between bin and pallet pricing. Each can quietly erase the discount a large reorder was placed to capture.

## How should storage costs change reorder sizes?

They argue for smaller, more frequent orders on bulky or slow moving SKUs, and for clearance deadlines on seasonal stock set by when projected storage will consume the remaining margin.
