Travel Time Calculator
The calculator estimates how long a trip takes: it divides distance by average speed, adds the time spent at stops and shows the arrival time from a chosen departure.
The formula is the easy part. The honest average speed is what matters, and it is almost always lower than the number on the signs — which is exactly why journeys overrun.
Common distances
With stops
6 h 8 min
Driving time: 5 h 38 min · In decimal hours: 5.63
Arrival time
14:08
Formula: time = distance ÷ average speed
Average speed is lower than the limit: towns, traffic lights, overtaking and climbs eat into it. Use 80–90 km/h for motorways and 60–70 km/h for mixed routes.
Formula and example
- Travel time = distance ÷ average speed.
- 450 km at an average of 80 km/h takes 5 hours 38 minutes.
- With a 30-minute stop the trip takes 6 hours 8 minutes.
- Leaving at 08:00 means arriving at 14:08.
Choosing an average speed
Average speed absorbs everything that happens between start and finish: towns, traffic lights, overtaking, climbs, roadworks. On a motorway limited to 110 km/h the real average rarely beats 90 km/h.
Working figures: 80–90 km/h for motorway running, 60–70 km/h for a mixed route through villages, 40–50 km/h through built-up areas and 20–30 km/h for city traffic at rush hour.
Travel time at different speeds
| Distance | 60 km/h | 80 km/h | 100 km/h |
|---|---|---|---|
| 20 km | 20 min | 15 min | 12 min |
| 50 km | 50 min | 38 min | 30 min |
| 70 km | 1 h 10 min | 53 min | 42 min |
| 90 km | 1 h 30 min | 1 h 08 min | 54 min |
| 100 km | 1 h 40 min | 1 h 15 min | 1 h 00 min |
| 200 km | 3 h 20 min | 2 h 30 min | 2 h 00 min |
| 400 km | 6 h 40 min | 5 h 00 min | 4 h 00 min |
| 450 km | 7 h 30 min | 5 h 38 min | 4 h 30 min |
| 800 km | 13 h 20 min | 10 h 00 min | 8 h 00 min |
| 1,000 km | 16 h 40 min | 12 h 30 min | 10 h 00 min |
What to add to the estimate
- Fuel and coffee stops run 10–15 minutes each; a proper meal is 40–60 minutes.
- On long drives a safe rhythm is a 15-minute break every two hours.
- Congestion on the approach to a large city easily adds an hour.
- In winter or heavy rain, drop the average speed by 10–15 km/h.
Frequently asked questions
How do I calculate travel time?
Divide the distance by your average speed and add the time spent at stops. 450 km at 80 km/h is 5 hours 38 minutes of driving.
What average speed should I use on a motorway?
For motorway running without towns, 80–90 km/h is realistic; a mixed route works out at 60–70 km/h.
Why does my navigation app show a different time?
Navigation knows the road profile and live traffic, while this calculation uses a single average speed. It is a planning tool, not a live forecast.
Does the calculator use maps or traffic data?
No. It works with the distance you enter and never calls a routing service.
How do I plan an overnight stop?
Estimate each day separately: 600–800 km is a comfortable day, beyond which fatigue builds and the average speed falls.
