Travel Time Calculator

Free Travel Time Calculator: quick travel time calculator for everyday decisions. No signup needed.

A travel time calculator estimates journey duration based on the distance to cover and the expected average speed for that route type. Enter a distance and a realistic average speed — accounting for junctions, speed limit zones, traffic conditions, and planned stops — and the result shows the estimated travel time in hours and minutes, together with an estimated arrival time if you enter your planned departure. This helps with journey planning, comparing transport modes, and calculating per-trip costs when combined with a fuel or running-cost calculator. Length Conversion Calculator and Weight Conversion Calculator extend this into full trip cost estimation using the journey time and distance.

Average journey speed is typically well below the posted speed limit due to acceleration and braking, traffic signals, junctions, and congestion. A 60 mph speed limit road averages 35–45 mph including all stops; a 70 mph motorway averages 55–65 mph off-peak and considerably less during morning and evening peak periods on busy corridors.

Enter the journey distance in miles or kilometres.
Enter your expected average speed — use a realistic figure that accounts for all speed changes, traffic, and junctions, not just the posted speed limit.
For multi-leg journeys (e.g. urban section + motorway + rural road), add each leg separately with its own distance and speed.
Optionally enter your planned departure time to calculate the estimated arrival time.
Read the result in hours and minutes — for example, 120 miles at an average of 50 mph = 2 hours 24 minutes total travel time.

Travel time formula

Travel time = Distance ÷ Average speed

Result in hours and minutes: hours = whole-number part; minutes = decimal fraction × 60

Worked example: 150 miles at 55 mph average speed. Travel time = 150 ÷ 55 = 2.727 hours = 2 hours 44 minutes. Departing at 08:30, estimated arrival = 11:14 before adding planned rest stops.

Multi-leg total: Sum each leg (distance ÷ speed) in hours and add stop durations separately. Convert the total hours to hours and minutes at the end.

Using your travel time estimate

Realistic average speeds by journey type

Typical average journey speeds for planning purposes (including acceleration, braking, junctions, but excluding extended stops): urban/city centre 10–20 mph; suburban A-road 25–35 mph; mixed rural and A-road 35–45 mph; motorway off-peak 55–65 mph; motorway peak-hour on busy corridors (M25, M6 near Birmingham) 20–40 mph. For journeys over 3 hours, the Highway Code recommends a 15-minute break every 2 hours — add this to your total travel time when planning arrival. Length Conversion Calculator uses travel time to estimate full trip costs including fuel.

Everyday Life tips and best practices

Add a 15–25% buffer to urban route estimates and 10–15% to motorway estimates — unexpected congestion, incidents, and roadworks account for the majority of arrival-time variability.
Check live traffic conditions before departure for motorway and A-road journeys — major incidents can add one to two hours to travel time on busy corridors during peak periods.
Plan rest stops proactively on journeys over two hours — driver fatigue contributes to approximately 20% of serious road accidents in the UK (Department for Transport data); scheduled breaks are safer and more efficient than unplanned stops.
Calculate each leg separately for mixed-road journeys — averaging a motorway and urban section into one speed underestimates motorway efficiency and overestimates urban speed, producing a less accurate travel time overall.

Average UK car journey: approximately 8.4 miles and 23 minutes per trip (DfT National Travel Survey, 2022).
Average motorway speed off-peak: approximately 60–65 mph for cars; approximately 55 mph including acceleration and deceleration near junctions.
Driver fatigue contributes to approximately 20% of motorway accidents and 10–15% of all fatal road accidents (RoSPA / DfT data).
Highway Code recommendation: take a break of at least 15 minutes every 2 hours of continuous driving on long journeys.

Common mistakes to avoid

Using the speed limit as the average speed — a 70 mph national speed limit road averages 55–65 mph in practice; congested motorways can average 20–40 mph during peak hours on the same route.
Forgetting stop time — a 3-hour drive with two 15-minute rest stops takes 3 hours 30 minutes total; always add planned stop durations to the travel time estimate for accurate arrival planning.
Not checking for planned roadworks — National Highways and devolved equivalents publish roadwork closures and temporary speed restrictions that can significantly extend journey times; check before long trips.
Underestimating urban peak-hour travel times — travel time through major cities can be 3–4 times longer during morning and evening peaks than the same route at off-peak times; use a peak-hour average speed for commute planning.

Speed limits in the UK are set under the Road Traffic Regulation Act 1984. The national speed limit (NSL) is 70 mph on motorways and dual carriageways and 60 mph on single-carriageway roads unless otherwise signed. Urban speed limits are set by local authorities; 20 mph zones are increasingly common in residential and school zones. Travel time estimates produced by this calculator are for planning purposes only and do not account for real-time traffic conditions, weather, road closures, or vehicle-specific speed restrictions such as motorway rules for towing vehicles (60 mph maximum). Always comply with current road signage and real-time navigation guidance.
