Travel Time Calculator
Distance divided by realistic average speed — plus the number people forget: what time that actually gets you there, and a sensible allowance for stops.
Your numbers
Average speed means door-to-door, including the slow parts — not the speed on the fast stretch.

How it works
Travel time is distance over average speed, and the average is where journeys are won and lost in planning. A route that is mostly motorway at 110 km/h with 20 km of town driving at 30 km/h does not average anything like 110 — the slow kilometres consume time out of all proportion to their length, because time adds up per kilometre, not per hour. The classic error is planning with the fastest speed of the trip; the honest figure for mixed roads is usually 60–75% of it.
The break allowance shown uses six minutes per hour of driving, the minimum rhythm most road-safety guidance converges on. On trips over four hours it is a floor, not a target.
Good practice & limits
- Plan with the average from a previous similar trip — your sat-nav history knows it exactly.
- Add a separate buffer for the first and last 15 minutes: leaving and arriving are never instant.
- If the arrival matters (a ferry, a flight), plan to the pessimistic average, not the optimistic one.
