Road Trip Time Calculator

Work out road trip time instantly with clear inputs, formula shown and shareable results.

About Road Trip Time Calculator

Journey time is distance divided by average speed plus break time. Average speed is always well below the speed limit once junctions, towns and traffic are included — planning on 90-95 km/h for motorway routes and 65-75 for mixed roads is realistic.

Formula

Journey time

total = distance / average speed + breaks x break length

Worked example

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What average speed should I assume?

About 90-100 km/h on motorways, 65-75 on mixed A roads and 45-55 on rural or urban routes. Satnav estimates are usually optimistic in traffic.

How often should I stop?

Every two hours or 200 km is the standard advice. Fatigue builds faster than most drivers notice, particularly after a large meal or on a monotonous route.
