Formula used
Base distance: use a known route distance, or calculate straight-line distance from coordinates with the Haversine formula.
Haversine formula: a = sin²(Δφ/2) + cos φ1 × cos φ2 × sin²(Δλ/2), c = 2 × atan2(√a, √(1−a)), d = R × c.
Combined factor: Road Factor × Traffic Factor × Terrain Factor × Weather Factor × Load Factor.
Factor-adjusted distance: Base Distance × Combined Factor.
Final driving distance: Factor-adjusted distance + (Factor-adjusted distance × Detour %).
Drive time: Final Distance ÷ Average Speed.
Stop delay hours: Stops × Average Stop Delay ÷ 60.
Total trip time: Drive Time + Stop Delay Hours.
Fuel used: Final Distance ÷ Fuel Efficiency.
Total trip cost: Fuel Cost + Labor Cost + Tolls + Miscellaneous Cost.
How to use this calculator
- Choose manual mode when you already know a planned route distance.
- Choose coordinate mode when you want a straight-line estimate from origin and destination coordinates.
- Pick the distance unit, then enter route labels for easier reporting.
- Select route, traffic, terrain, weather, and load factors that match expected conditions.
- Add detour allowance, stop count, stop delay, average speed, and fuel efficiency.
- Enter fuel price, driver hourly cost, tolls, and any other trip costs.
- Press Estimate Distance to show the results above the form.

FAQs
1. What does this calculator estimate?
It estimates driving distance, drive time, stop delay, fuel use, fuel cost, labor cost, and total trip cost for logistics planning.
2. Is this a live map routing tool?
No. It is a planning estimator. It uses your manual base distance or coordinate-based straight-line distance, then applies logistics adjustment factors.
3. When should I use coordinate mode?
Use coordinate mode when you know both locations but do not have a mapped road distance yet. The estimator converts straight-line distance into a practical road estimate.
4. Why are traffic and terrain factors separate?
Traffic affects travel conditions and route behavior. Terrain reflects road shape, elevation, and handling difficulty. Keeping them separate gives more realistic estimates.
5. What should I enter for fuel efficiency?
Enter km/L when using kilometers. Enter mpg when using miles. Match fuel price to the same fuel unit for consistent cost output.
6. Does the calculator include stop delays?
Yes. It multiplies your number of planned stops by the average delay per stop, then adds that time to the drive estimate.
7. Can I use it for dispatch budgeting?
Yes. It is useful for dispatch planning, trucking estimates, fuel budgeting, customer quoting, lane comparison, and schedule preparation.
8. Why is my final distance higher than my base distance?
The calculator increases the base figure using road pattern, traffic, terrain, weather, load, and detour allowances. That creates a more practical driving estimate.
