How to Calculate Shipping Lead Times
Shipping lead time is the total duration from when an order is placed until it reaches the customer. It consists of three primary components: processing time, transit time, and clearance time.
The Shipping Time Formula
Total Time = (Distance ÷ Speed) + Handling Time + Customs Buffer
Factors Influencing Shipping Speed
- Transport Mode: Air freight is the fastest (approx. 800 km/h) but most expensive. Ocean freight is the slowest (approx. 35 km/h) but most cost-effective for bulk goods.
- Handling & Processing: The time it takes for a warehouse to pick, pack, and label a shipment.
- Port Congestion: High traffic at maritime ports or airports can add 2–7 days to the lead time.
- Customs Clearance: International shipments must pass through regulatory checks, which vary by country.
Lead Time Example
If you are shipping a 5,000 km route via Ocean Freight:
- Transit Time: 5,000 km ÷ 35 km/h = 143 hours (~6 days).
- Handling: 2 days for loading/unloading.
- Total Lead Time: 8 days.
