Driving Time Calculator

Estimate driving time from user-entered distance, speed, and rest stops. No live traffic.

Example: 240 miles at 60 mph, with a 15-minute rest every 2 hours of driving, is 4 hr of driving, 2 rest stops (30 min), and 4 hr 30 min in total. Use the same unit for distance and speed. The miles or kilometers choice on the form is a label. It does not convert the numbers. This is not live traffic and not an address-to-address route.

Distance and speed unit

The duration is distance divided by speed. This choice labels the numbers. It does not convert miles to kilometers.

Distance and speed

4 hr 30 min

Driving 4 hr plus 2 rest stops (30 min).

Unit label: miles and mph. Changing the label does not convert the numbers.

This uses the speed you entered. It is not a mapped route and not a live-traffic estimate.

No departure time was entered, so this result is a duration only.

Assumptions

Driving minutes = distance / average speed × 60 for each leg.
Rest stops = floor(driving hours / rest interval) × rest length.
Average speed is user-entered. There is no live traffic, weather, or routing data.
