This calculator estimates how long a trip will take. Enter the distance, your expected average speed and the total time you plan to stop, and you get the driving time, the total trip time and the distance in kilometres.

Formula

Driving time (minutes) = distance ÷ average speed × 60. Total time = driving time + stops.

  • d: distance in miles (the formula works the same in km with km/h)
  • v: expected average speed in the same distance unit per hour
  • stop: breaks, fuel and meals in minutes

Worked Example

A 275-mile trip at 62 mph with 30 minutes of stops.

  1. 275 ÷ 62 = 4.4355 h; × 60 = 266.13 min = 4:26:08
  2. 266.13 + 30 = 296.13 min = 4:56:08
  3. 296.13 ÷ 60 = 4.94 h
  4. 275 × 1.609344 = 442.6 km

Limits and common mistakes

  • Use a realistic average, not the speed limit: traffic, towns and junctions pull it down.
  • Keep distance and speed in matching units (miles with mph, km with km/h).
  • Time-zone changes are not included.
  • Long drives usually need a break every two hours or so; add those minutes to the stop time.
  • To find the speed you need to arrive on time, divide the distance by the hours available.
