Road Trip Time & Stops Calculator

How it works

Driving time = Σ (leg distance ÷ leg speed) × (1 + traffic buffer) · Days = ceil(driving time ÷ max hours per day), driving split evenly · Stops per day = ceil(daily driving ÷ stop interval) − 1 · Stop interval = the shorter of your rest interval and range ÷ speed · Total time = driving + stops × minutes + meal breaks × minutes · Arrival = departure + total time (+ overnight breaks) + time-zone change

Map apps quote driving time at a steady speed, but a real trip adds fuel, food and bathroom stops, slow traffic and, on long hauls, nights on the road. This calculator divides each leg’s distance by a realistic average speed — always lower than the limit once towns, merges and trucks are counted — and adds an optional traffic buffer. It then splits the driving evenly across days so no day exceeds your limit, places a stop each time your chosen interval passes (none is needed on arrival), lets a meal break replace one of each day’s stops, and spaces stops more tightly if your fuel tank or EV range runs out first. With a departure date and time it builds a day-by-day itinerary: each later day starts at your usual departure time, or after your minimum overnight break if you arrived late. The final arrival can be shifted into the destination’s time zone. Optional fuel economy, fuel price and lodging rate add a quick trip budget; for a detailed fuel and per-person split, use the fuel trip cost calculator.

Worked example

600 miles at 60 mph is 10 hours of driving. With a 9-hour daily limit the drive is split into 2 days of 5 hours. Stopping every 2.5 hours means one stop on each day (ceil(5 ÷ 2.5) − 1 = 1), and the default single meal break replaces it, so each day has one 45-minute meal stop: 10 h of driving + 1 h 30 min of stops = 11 h 30 min on the road. Leaving at 8:00 am, day 1 ends at 1:45 pm and day 2 runs from 8:00 am to 1:45 pm. At 25 mpg the trip uses 24 gallons, about $84 at $3.50 a gallon.
