How to Calculate Shipping ROI: 7 Tips for Global Freight
UNCTAD reported 12.3 billion tonnes of maritime trade in 2023. That figure shows sea freight’s enormous scale, but volume alone does not prove profitability. Use it as market context, not as your business forecast.
Start with a simple formula: shipping ROI equals added profit minus logistics cost, divided by logistics cost. Compare sea, air, rail, and road using the same shipment weight, distance, and delivery promise. A 20-ton container moving from Asia to Europe may favor sea freight. A smaller, urgent shipment may justify air freight despite its higher cost. Rail can balance speed and expense on selected land corridors.
Use real operating details. Record freight charges, fuel surcharges, insurance, port handling, customs processing, storage, damage, and missed-sales costs. Then measure transit time and delivery reliability. One late container can erase the savings from a cheaper rate. Small details matter.
My first model underestimated inventory cost because it counted transport only. That mistake changed the preferred mode. I also treated average transit times as fixed, which was unrealistic during congestion. Test three scenarios: normal, delayed, and peak season. Recheck rates monthly, and separate country-specific taxes from carrier costs. UNCTAD’s 12.3-billion-tonne figure provides authority and scale, but your invoices, delivery records, and customer penalties decide the actual ROI.
