Road Trip Planner Calculator (Days, Breaks and Fuel Stops)
How many days a road trip takes, how many breaks and fuel stops it needs, and the total time on the road, from the distance, speed and how long you want to drive each day.

What this tool does
The hours at the wheel are only part of a long drive: breaks add up, and each overnight stop is a day the clock restarts. Road-safety advice often suggests a break at least every two hours, and fatigue is a big factor in long-distance crashes, so a daily limit of 8 hours is a common planning figure for a single driver. For fuel, use the distance you can safely drive on a tank including a reserve, rather than the theoretical maximum, and remember that fuel stops can double as breaks.
Formula
hours = distance ÷ speed · days = ⌈hours ÷ daily limit⌉ · breaks = ⌈hours ÷ interval⌉ − 1 · fuel stops = ⌈distance ÷ range⌉ − 1

Limitations
- The result is an estimate based only on the values you type. Real situations often include factors this calculator does not know about.
- The calculation runs at full precision and only the display is rounded. If you copy an intermediate value and retype it, small differences can appear.
