Travel Time Calculator
Estimate your total driving time, including rest breaks, based on distance and average speed.
How Travel Time Is Estimated
The calculator divides your trip distance by your average speed to estimate driving time. To account for stops, it also estimates the number of rest breaks by dividing your distance by your rest break frequency and rounding down, then multiplies that by your break duration to get your total break time. Adding driving time and total break time together gives your total travel time.
Impact of Rest Breaks
Rest breaks are an important part of safe driving on long trips, but they add to your total travel time. Even short, frequent breaks can add up over a long distance. Entering a realistic rest break frequency and duration helps you plan arrival times more accurately and avoid underestimating how long a trip will take.
FAQ
How is travel time estimated?
Driving time is your distance divided by your average speed. If you enter a rest break frequency, the calculator estimates how many breaks you'll take by dividing your distance by the break frequency and rounding down, then multiplies that by your break duration to get your total break time. Total travel time adds driving time and total break time together.
What happens if I don't enter a rest break frequency?
A rest break frequency of 0 means no breaks are included in the estimate. Total travel time will then be the same as your driving time.
How do rest breaks affect total travel time?
Each rest break adds its duration to your total travel time. For example, three 15-minute breaks add 45 minutes to your trip. Longer trips with frequent breaks can add up to significant extra time.
How is the number of breaks calculated?
The number of breaks is your distance divided by your break frequency, rounded down to the nearest whole number. For example, a 250-mile trip with a break every 100 miles results in 2 breaks.
Can average speed account for traffic?
Yes, but you'll need to estimate it yourself. Using a lower average speed than your vehicle's top speed can help account for traffic, stops, and varying road conditions.
