Planning a road trip is easier when you know what the journey may cost before you leave. Use this Road Trip Cost Calculator to estimate fuel expenses, tolls, lodging, food, parking, and other travel costs. Enter your driving distance, vehicle MPG, gas price, and trip details to calculate your estimated total budget and cost per person.
How to Calculate Road Trip Costs
Your road trip cost depends on how far you drive, your vehicle’s fuel efficiency, the number of nights you stay away, and how much you spend along the way. The calculator combines these expenses to estimate your total trip budget.
For fuel, it uses your total driving distance and miles per gallon (MPG) to estimate the gallons needed. It then multiplies the fuel required by your gas price. For a round trip, make sure you enter the one-way distance and select the round-trip option.
What Expenses Should You Include in a Road Trip Budget?
Fuel is only one part of the total cost. A realistic road trip budget should account for the following:
- Gas or fuel: Based on driving distance, vehicle MPG, and the price per gallon.
- Tolls: Include expected highway and bridge tolls for your route.
- Lodging: Enter the nightly cost and number of paid nights.
- Food: Estimate your daily food spending for every traveler.
- Parking and local transportation: Include parking fees, public transit, and other local travel.
- Other expenses: Allow for attractions, activities, snacks, and unexpected purchases.
You can also include a budget buffer to prepare for costs that are difficult to predict. For additional planning guidance, explore our tips to control travel expenses and avoid hidden travel costs.
How Much Will Gas Cost for Your Road Trip?
Fuel cost is determined by three main factors: total driving distance, vehicle fuel economy, and gas price.
For example, suppose you drive 600 miles round trip in a vehicle that averages 30 MPG, with gas priced at $3.50 per gallon. You would need approximately 20 gallons of fuel, costing about $70.
The estimate will change if your route is longer, fuel prices increase, or your vehicle gets lower mileage. If you plan to drive through multiple destinations, include the additional miles rather than calculating only the distance between your starting point and final destination.
How to Split Road Trip Costs Between Travelers
Traveling with friends or family can make a trip more affordable when everyone shares eligible expenses. The calculator estimates the total cost per person by dividing the overall trip budget by the number of travelers.
For example, a trip costing $900 shared equally by three people would work out to $300 per person. Before dividing expenses, agree on which costs will be shared, such as gas, tolls, and lodging, and which expenses each traveler will pay individually.
Plan Your Road Trip Without Overspending
Once you know your estimated cost, compare it with the amount you can comfortably afford. You may be able to lower expenses by choosing more fuel-efficient routes, comparing accommodation prices, packing snacks, or reducing unnecessary stops.

Remember that the calculator provides an estimate rather than a guaranteed final price. Actual costs depend on traffic, route changes, fuel prices, accommodation rates, and your spending habits. Update your inputs as your plans become more certain to create a more useful budget.
