Example
A 600-mile trip in a car getting 28 MPG at $3.60/gal burns about $77 in fuel. Add $20 in tolls, 2 nights of lodging at $120 ($240) and 3 days of food at $40 ($120), and the trip runs about $457 total. Split between 2 travelers, that is roughly $229 per person.
How it works
Fuel = distance ÷ MPG × fuel price. Total = fuel + tolls + (nights × lodging per night) + ((nights + 1) × food per day). Cost per person = total ÷ travelers. Food is charged for nights + 1 days so both travel days are covered.
Good to know
Planning a road trip is really a budgeting exercise dressed up as a map. This tool pulls together the four costs that dominate a driving vacation — gasoline, tolls and parking, hotel nights, and meals — and rolls them into one total, then divides that total by however many people are splitting the bill. It updates as you type, so you can compare a shorter route, a more fuel-efficient rental, or a cheaper motel in seconds.
The fuel figure is the one that trips people up. It depends on distance, your vehicle's real-world MPG, and the price at the pump, not just how far you are driving. A thirsty SUV at 18 MPG can cost more than double a hybrid at 45 MPG over the same route, so it is worth entering an honest highway number rather than the sticker rating. Remember the mileage should reflect the round trip if you are coming home the same way.
Food is modeled across nights + 1 days, on the logic that a two-night trip still means eating on three calendar days — the day you leave, the day in between, and the day you return. Lodging, by contrast, is counted per night. If your crew grabs cheap fast food or packs a cooler, drop the per-day food figure; if you plan sit-down dinners, push it up.
Treat the result as a planning estimate, not a locked-in quote. It does not include vehicle wear, one-off attraction tickets, souvenirs, or unexpected repairs, and gas prices swing by region and season. Pad the total by 10–15% for a comfortable cushion.
Frequently asked questions
How much should I budget for a road trip?
Start with fuel (distance ÷ MPG × gas price), then add tolls, lodging per night, and daily food per person. This calculator sums all four and splits the total by the number of travelers, giving a realistic baseline you can pad by 10–15% for extras.
Does this include food and hotels, not just gas?
Yes. It adds lodging for each night and food for nights + 1 days on top of fuel and tolls, so the total reflects the whole trip rather than just what you spend at the pump.

People also ask
How do you calculate gas cost for a road trip?
Divide the total distance by your vehicle's miles per gallon to get the gallons needed, then multiply by the price per gallon. For a 600-mile trip at 28 MPG and $3.60/gal, that is 600 ÷ 28 × 3.60 ≈ $77.
How do you split road trip costs between friends?
Add every shared expense — fuel, tolls, lodging and food — into one total, then divide by the number of people. This tool does the split automatically and shows the per-person figure alongside the total.
What costs should a road trip budget include?
Fuel, tolls and parking, lodging, and meals are the big four this tool covers. Beyond that, budget separately for attraction tickets, souvenirs, snacks, and a buffer for vehicle wear or unexpected repairs.
How much will gas cost for a 1,000 mile trip?
Gas cost = distance / MPG x price per gallon. At 28 MPG and $3.60 per gallon, a 1,000-mile trip burns 1,000 / 28 = 35.7 gallons, costing 35.7 x $3.60 = about $129. A less efficient vehicle at 20 MPG would use 50 gallons and cost $180 at the same price. Pump prices change constantly, so plug in the current price along your route for a real figure.
How much will gas cost for a 3,000 mile trip?
At 28 MPG and $3.60 per gallon, 3,000 miles uses 3,000 / 28 = 107.1 gallons, so gas costs about 107.1 x $3.60 = $386. At 20 MPG the same trip needs 150 gallons, or $540. Because fuel is only part of a long trip, add tolls, lodging and meals in the calculator to see the full budget and the per-person split.
How long does it take to drive 1,200 miles?
At a 60 mph average, 1,200 miles is 1,200 / 60 = 20 hours of driving; at 65 mph it is about 18.5 hours. Realistic averages including fuel, food and rest stops are lower, so most people split 1,200 miles into two long days of roughly 10 hours each. If you plan an overnight, enter 1 night of lodging and 2 days of food in the calculator.
