Road Trip Cost Calculator
Total road trip cost from distance, fuel efficiency, gas price, and days on the road.
About the Road Trip Cost Calculator
The Road Trip Cost Calculator gives you an instant answer from just a few inputs — total distance, fuel efficiency, gas price, and more. It runs entirely in your browser, so the numbers you enter stay private and never touch a server, and the result recalculates the moment you change a value. It's free to use with no sign-up, no limits, and nothing to install.
Worth Knowing
The lodging line multiplies by days minus one on purpose: a three-day trip needs two nights, and budgeting a night for the day you arrive home is the most common overcount in a road-trip estimate. Fuel is the line most likely to be underestimated, in the other direction. The mpg figure on the window sticker is an EPA test result, and real-world consumption on a trip is usually worse — a fully loaded vehicle, a roof box, sustained speeds above 65, air conditioning, mountain grades, and headwinds each cost several percent. Use your own observed mpg if you know it; if you do not, taking 85% to 90% of the rated highway figure is closer to reality than the sticker. Three costs sit outside what this calculates. Tolls can be substantial on some corridors, particularly in the Northeast, and a rental without a transponder may be billed at a penalty rate. City parking is easy to forget and frequently exceeds the fuel cost of getting there. And fuel is not the true cost of driving: the IRS standard mileage rate, which folds in depreciation, maintenance, and tyres, has run around 70 cents a mile, so a 2,000-mile trip carries real vehicle wear well beyond the gas. If you are driving an EV, the fuel line needs replacing entirely — cost per kWh at home versus at a highway fast charger differs by a factor of three or more, and the charger network, not the price, usually shapes the route.
