Worked Example

$10M freight, $380K staff, 10% freight saving, 60% staff reduction, $320K 4PL fee, $45K tech saving.

Freight saving: $1,000,000
Staff saving: $228,000
Tech saving: $45,000
Total: $1,273,000
Net after fee: $953,000. ROI: 298%

At $10M freight spend, 4PL outsourcing almost always pays back significantly. The key is selecting a provider with genuine carrier leverage (not just a middleman) and clear performance SLAs with gain-sharing.
