| Origin | Destination | Mode | Distance (km) | Handling (h) | Customs (h) | Buffer (%) | Est. Total (h) |
|---|---|---|---|---|---|---|---|
| Karachi, PK | Dubai, AE | SEA | 1,200 | 18 | 12 | 12 | ~82 |
| Lahore, PK | Riyadh, SA | ROAD | 1,800 | 10 | 8 | 10 | ~51 |
| Islamabad, PK | London, GB | AIR | 6,200 | 14 | 20 | 15 | ~47 |
This estimator combines movement time, operational time, and a risk buffer:
If you disable weekends, the tool skips Saturday and Sunday when adding whole transit days. Cutoff and dispatch frequency shift departures to the next valid cycle.
Accurate distance inputs drive reliable transit estimates. On road lanes, a 5% error on 1,800 km changes travel time by about 1.4 hours at 65 km/h. For air and sea, distance is less sensitive than dwell, yet it still affects block time and sailing days. Use a consistent lane method so comparisons stay fair. Maintain versioned lane records to support audits and improve forecasting accuracy over time continually.
Default speeds are air 750 km/h, sea 30 km/h, road 65 km/h, and rail 80 km/h. Override speed for slow steaming, mountainous routes, or restricted corridors. Example: reducing sea speed from 30 to 24 km/h on 1,200 km increases travel time from 40.0 to 50.0 hours before handling, customs, and buffers.
Operational time combines handling, customs, and stopovers. With 18 handling hours, 12 customs hours, one stopover, and 8 stopover hours, the base operational block is 38 hours. Express service reduces this block slightly, while economy increases it. Treat values as recent averages, then refine using exception logs.
Cutoff and dispatch frequency control when the clock starts. If a booking is after a 17:00 cutoff, dispatch shifts to the next cycle at 09:00. A frequency of 2 aligns departures to every other day, adding up to 24 hours of waiting. If weekends are disabled, Saturday and Sunday are skipped for whole-day counts.
Risk inputs scale operational time using a blended multiplier for weather, congestion, and seasonality. A setting like 3, 4, and 2 yields a multiplier near 1.056, increasing ops hours without overstating travel. Buffer percentage then applies to the full pre-buffer time. Many teams start at 10–15% and tighten as lanes stabilize.
CSV and PDF outputs create an audit trail for planning meetings and customer updates. Store exports with the shipment reference and assumptions used. When sharing, include the breakdown of travel, operations, and buffer hours plus the confidence score. Compare estimated versus actual arrival monthly to recalibrate dwell inputs and risk levels.
Risk increases the operational portion using a multiplier for weather, congestion, and seasonality. It helps reflect variable delays at ports, hubs, and borders without inflating pure travel time.
Use the distance method you apply operationally. Lane distance from your routing or TMS is best for road and rail. For air or sea, use consistent origin–destination legs so scenarios remain comparable.
Start with 10–15% on stable lanes, higher on new lanes or peak periods. Then compare estimated versus actual arrivals and adjust buffer and dwell inputs monthly to reduce missed promises.
If the selected departure is after the cutoff hour, dispatch shifts to the next cycle. Frequency aligns dispatch to a repeating day pattern, which can add waiting time before transit begins.
It is a heuristic 0–100 indicator based on risk levels and buffer size. Higher confidence means fewer assumed disruptions and a healthier contingency margin, not a guarantee of on-time delivery.
This version exports the most recent calculation to CSV or PDF. Run a scenario, export, then adjust inputs and repeat. You can combine exported CSV rows later in a spreadsheet for comparisons.
