How do you calculate warehouse utilization?

Utilization = used ÷ capacity, as a percent. For pallet positions, that's occupied positions divided by total positions — 8,300 of 10,370 is 80%. For cube, it's stored volume divided by available volume — 210,000 of 300,000 cubic feet is 70%. They measure different things and both matter.

What is the difference between position utilization and cube utilization?

Position utilization counts a slot as full whether the pallet in it is tall or short. Cube utilization measures how much of the actual volume is used. A building can be 85% of positions full but, if those pallets only fill 75% of their slot's cube, be using just under 64% of the cube it pays for. Position utilization flatters you; cube utilization tells the truth about wasted space.

Why shouldn't a warehouse run at 100% utilization?

Because you need empty positions to work. Receiving, put-away, re-slotting, and returns all need somewhere to go. At 100% every move becomes a shuffle, travel time balloons, and a single large inbound has nowhere to land. The goal is high enough to be efficient, with enough slack to stay fluid — usually around 85%.

What Is a Good Warehouse Utilization Rate?

Q: What is a good warehouse utilization rate?

For pallet positions, the practical sweet spot is the low-to-mid 80s percent — around 85%. That's full enough to spread fixed cost but with enough empty slots to receive, put away, and re-slot without gridlock. Running above about 90% usually slows everything down; running low wastes money you're already paying.

Utilization is used ÷ capacity, as a percent. The healthy target for pallet positions is about 85% — not 100%, because you need empty slots to actually work. And position utilization isn’t the same as cube utilization: your racks can look full while half the air you pay for sits empty. Here’s how to measure both, and what a good number looks like.

The formula

Utilization = used ÷ capacity. For pallet positions, that’s occupied positions over total positions: 8,300 of 10,370 is 80% used, 20% free. For cube, it’s stored volume over available volume: 210,000 of 300,000 cubic feet is 70%. Same formula, two very different lenses.

Position vs. cube: the number that flatters you

Position utilization counts a slot as full whether the pallet is stacked to the beam or knee-high. Cube utilization measures the air. That gap is where money hides: if 85% of positions are occupied but those pallets only fill 75% of their slot’s cube, your real cube utilization is 0.85 × 0.75 = about 64%. The racks look nearly full; you’re paying for a third of the volume for nothing.

Position utilization tells you how it looks. Cube utilization tells you what you’re wasting.

Why 100% is the wrong target

It’s tempting to chase a full building, but empty positions are the room you work in. Receiving, put-away, re-slotting, returns, and the odd oversized inbound all need somewhere to land. Push past about 90% and every move becomes a shuffle: travel time climbs, put-away stalls, and a single big delivery has nowhere to go. The practical sweet spot is the low-to-mid 80s — efficient, but still fluid. Below the 70s, you’re paying rent on air.

Utilization is a cost lever, not just a metric

Every empty slot loads its cost onto the pallets that are there. That’s why utilization drives cost per occupied position directly: at 80% a position costing $96 a year works out to about $120 per stored pallet, and at 60% it’s past $160. Raising utilization is one of the few warehouse moves that cuts unit cost without cutting service.

How to raise it

Three levers do most of the work: slotting (put fast movers where they belong and match pallet heights to beam heights to recover cube), SKU rationalization (dead stock is occupied positions earning nothing), and rack choice (denser rack for deep, slow SKUs). Size the capacity you’re filling with the pallet positions guide, and see how it all rolls into cost in the warehouse cost & space guide.
