Consolidation Savings Planner

Calculate freight savings from consolidating partial-fill shipments into fuller loads, using volume-conserving math, not a naive utilization-gap estimate.

Resources

Reference Landed Cost: The Duty Line Everyone Underestimates A $10 unit cost, $8 freight, 25% duty rate. Duty on cost alone: $2.50. Duty on the real dutiable base, cost plus freight: $4.50. The $2 gap is not a rounding error, it is a fixed mistake in what the duty rate applies to.

How this works

Total monthly volume shipped, in container-equivalents, is shipment count times current utilization. That same volume, moved at a target utilization instead, needs volume divided by the target. The difference between the current shipment count and that number is the shipments actually eliminated.

Key terms

Container utilization: the current average fraction of a container's capacity used per shipment.
Consolidation threshold: the target fill level once shipments are combined.

Assumptions

Volume shipped is conserved, no volume growth or shrinkage from consolidating

Limitations

One lane and one freight rate, not a multi-lane network optimization

Sources

Standard freight consolidation / load-fill optimization practice.

Worked example

At 45.5% average utilization across 20 shipments/month, consolidating to an 85% target volume-conserving math needs 11 shipments, saving 9, worth $10,800/month at $1,200/shipment. A naive gap-subtraction estimate would understate this by a full shipment.
