This chart shows how each time component contributes to the final estimate.
Example Data Table
| Scenario | Distance (km) | Speed (km/h) | Handling + Delays (hrs) | Buffer (%) | Estimated Total (hrs) |
|---|---|---|---|---|---|
| Regional Express | 320 | 65 | 9 | 7 | 14.21 |
| National Standard | 850 | 55 | 24.5 | 10 | 43.50 |
| Cross-Border Economy | 1400 | 48 | 38 | 16 | 78.47 |
Formula Used
Movement Hours = Distance ÷ Average Speed
Pre-Buffer Hours = Movement Hours + Pickup Hours + Warehouse Hours + Customs Hours + Weather Delay Hours + Traffic Delay Hours + Rest Hours + Cutoff Hours
Buffer Hours = Pre-Buffer Hours × (Buffer % ÷ 100)
Total Delivery Hours = Pre-Buffer Hours + Buffer Hours
Total Delivery Days = Total Delivery Hours ÷ 24
Service level applies a multiplier to movement time and slightly adjusts operational buffer.
How to Use This Calculator

- Use the CSV or PDF buttons to export the estimate.
FAQs
1. What does this calculator estimate?
It estimates total delivery time by combining transit movement, handling, customs, delays, rest periods, missed cutoffs, and a configurable risk buffer.
2. Why is average speed important?
Average speed directly affects movement time. Lower realistic speed values usually produce better estimates than ideal highway speeds because actual routes include stops and congestion.
3. What is the risk buffer?
The risk buffer adds protective time to the estimate. It helps account for uncertainties that are hard to predict exactly, such as lane restrictions or terminal queues.
4. How does missed cutoff affect delivery time?
If a shipment misses a dispatch cutoff, it may wait for the next departure cycle. This calculator adds 24 hours when that option is selected.
5. Can I use this for international shipments?
Yes. Add customs hours, realistic delay values, and a suitable buffer. International estimates become more useful when you model documentation and clearance time carefully.
6. What service level should I choose?
Choose express for priority shipments, standard for balanced planning, and economy for cost-focused delivery. Each option changes movement assumptions and buffer behavior.
7. Is the estimated arrival guaranteed?
No. It is a planning estimate, not a carrier guarantee. Real conditions may still create earlier or later arrivals than the calculated value.
8. Can I export the results?
Yes. Use the CSV button for spreadsheet-friendly output and the PDF button for print-ready documentation of the estimated delivery timeline.
