What This Calculator Does
This delivery time calculator estimates total transit time for freight shipments accounting for distance, average speed, FMCSA Hours of Service (HOS) regulations, mandatory rest periods, loading and unloading times, and overnight stops. It provides a realistic delivery timeline that goes beyond simple distance-divided-by-speed calculations.
The Formula
Driving hours equal distance divided by average speed. FMCSA regulations limit drivers to 11 hours of driving within a 14-hour on-duty window, followed by 10 hours off duty. Rest breaks of at least 30 minutes are required after 8 hours of driving. These regulations add significant time beyond raw driving hours.
Step-by-Step Example
Enter distance and speed
Input total distance (1,200 miles) and average speed (55 mph). Raw driving time: 21.8 hours.
Set HOS limits
Maximum 11 driving hours per day (FMCSA standard). This means 2 full driving days for this trip.
Add loading and unloading
Typical loading: 2 hours. Unloading: 2 hours. Total handling: 4 hours.
Review total time
21.8 hrs driving + 4 hrs handling + 1 overnight (10 hrs) + rest breaks = approximately 38 hours total.
Real-World Use Cases
Dispatch Planning
Set realistic delivery appointments and communicate accurate ETAs to customers and receivers.
Driver Scheduling
Plan driver assignments and relay points for long-haul shipments within HOS compliance.
Supply Chain Planning
Estimate lead times for inventory replenishment and production scheduling.
Common Mistakes to Avoid
Ignoring Hours of Service regulations. A 1,000-mile trip cannot be completed in one driving day regardless of driver willingness.
Using highway speed limits as average speed. Traffic, fuel stops, weigh stations, and weather reduce actual averages to 45-55 mph.
Not accounting for loading and unloading detention time, which commonly adds 2-4 hours per stop.
Forgetting that delivery appointments may not align with arrival times, causing additional waiting.

Accuracy and Disclaimer
Delivery time estimates are approximations based on general assumptions. Actual transit times vary due to weather, traffic, road construction, driver availability, HOS exceptions, and carrier operational practices. Always confirm delivery schedules with your carrier.
