How do you calculate container utilization?

Divide the volume loaded by the usable container capacity. Loading 2,100 ft³ into a 2,390 ft³ container gives 2,100 ÷ 2,390 = 87.87% utilization.

What is a good container fill rate?

Most import programs target 85-90% cube utilization; above 90% is strong. The example's 87.87% is solid but sits 2.13 points below a 90% target, so there is still room to consolidate.

Why isn't my container 100% full?

Pallet footprints, dunnage, stacking limits, and product geometry leave unavoidable void. Even a well-planned load rarely exceeds the low-to-mid 90s, which is why 90% is a common practical target rather than 100%.

What is the gap to target and why does it matter?

It's your target fill rate minus actual utilization, in points. A 2.13-point gap means you're shipping slightly more air than planned; multiplied across many containers, closing that gap can drop a container from an annual program.

Should I use volume or weight for utilization?

Use whichever binds first. Light, bulky goods are volume-limited and this cube calculation applies directly; dense goods hit the container's weight cap before it fills, so check payload separately.

How do I improve container utilization?

Standardize pallet patterns to the container's internal dimensions, mix dense and bulky SKUs, reduce oversized packaging, and consider floor-loading. Small changes in case dimensions can add several points of fill.

Supply Chain & Procurement calculator

Container Utilization Calculator

Container utilization is the share of a shipping container's usable cube that your loaded cargo actually occupies, and it is one of the fastest levers logistics and inbound-freight teams have to cut cost per unit. Every cubic foot of air you ship is freight you pay for and don't use, so raising fill from the high 80s toward the low 90s can eliminate whole containers over a year. Import and warehouse planners use it to audit load plans, set pallet-configuration standards, and hold 3PLs accountable to a target fill rate. It matters because ocean and drayage costs are largely fixed per container — utilization is what turns those fixed costs into a competitive landed cost.

What this calculator does

Calculate container utilization for Supply Chain & Procurement — cube or weight loaded against container capacity.
Use it to cut freight cost per unit by filling containers in Supply Chain & Procurement.
Computes the percentage of usable container capacity filled by loaded cargo and the gap in points between that utilization and your target fill rate.

Formula used

Container utilization = volume loaded ÷ container capacity
Gap to target = target fill − utilization

Inputs explained

Cargo volume loaded:
Usable container capacity:
Target fill rate:

How to use the result

Use it when auditing a load plan before booking, benchmarking a 3PL's stuffing performance, or deciding whether cargo can be consolidated into fewer containers.
It compares volume to volume; a load can hit high cube utilization yet still be weight-limited (or vice versa), so pair it with a weight check before assuming a container is truly full.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity (Federal Reserve, May 2026). New factory orders are up 2.3% year over year (Census).
Sourcing currencies as of 2026-07-02 (Federal Reserve H.10): 6.7886 CNY and 17.4524 MXN per USD. Landed-cost comparisons move with these daily rates.
U.S. iron and steel imports ran $2.1B in May 2026 (Census International Trade). The U.S. ran a trade deficit of $0.4B in the category that month. Import volumes are the pressure gauge behind tariff and reshoring decisions.
