Deciding whether to drive or fly for your next trip? This calculator compares the total cost of both options so you can make a confident decision. Here is how to get an accurate comparison.
- Enter the one-way distance. Use Google Maps to find the driving distance between your starting point and destination. The calculator uses this to compute fuel costs and drive time.
- Set your vehicle details. Enter your car's real-world MPG and the current gas price per gallon. Using your actual fuel economy (not the EPA estimate) gives a more accurate result.
- Enter flight details. Add the number of travelers and the airfare per person. Include taxes and fees in the airfare figure for a fair comparison.
- Add hotel costs for driving. Long drives often require overnight stops. Enter the number of hotel nights you would need and the cost per night. If the drive is short enough for a single day, set hotel nights to zero.
- Review the results. The calculator shows which option is cheaper and by how much. The breakdown includes drive fuel cost, hotel cost, total fly cost, and estimated drive time. Use the Share button to send the comparison to your travel companions.
About the Drive or Fly Calculator
The decision to drive or fly depends on more than just the ticket price. Gas costs, hotel stays during long drives, and the number of people traveling all shift the math. For solo travelers on long trips, flying is usually cheaper. For families or groups on shorter routes, driving often wins by a wide margin. This calculator factors in fuel cost (distance divided by MPG, multiplied by gas price), hotel expenses for overnight driving stops, and total airfare for your group. It gives you a clear, side-by-side cost comparison so you can pick the smarter option for your budget.
Frequently Asked Questions
At what distance is it cheaper to fly than drive?
There is no single breakeven distance because it depends on the number of travelers, gas prices, and airfare. As a general guideline, solo travelers often find flying cheaper for trips over 400-500 miles, especially when hotel nights are needed for driving. Groups of 3 or more can usually drive up to 1,000 miles or more before flying becomes cheaper, since gas costs are split but each person needs a plane ticket.
What costs should I include in the airfare?
Include the full ticket price with taxes and fees. If you plan to check bags, add those fees too. You may also want to factor in ground transportation at your destination (rental car, rideshare, or shuttle), since driving means you already have your car with you. For a conservative comparison, add $30-50 per person for airport parking or rideshare to and from the airport.
Does this calculator account for the value of time?
The calculator shows drive time so you can factor in time yourself, but it does not assign a dollar value to your hours. If you want to include time cost, a common approach is to multiply your hourly wage by the extra hours driving takes compared to flying. For example, if driving takes 8 hours and flying takes 3 hours (including airport time), the difference is 5 hours. At $30 per hour, that adds $150 to the effective cost of driving.
Should I use round-trip distance?
Enter the one-way driving distance. The calculator computes fuel cost for a one-way trip. If you want to compare round-trip costs, double both the distance input and the airfare per person (using the round-trip ticket price). Also adjust hotel nights to cover both directions if overnight stops are needed each way.
