Road Trip Cost Calculator

A road trip feels cheaper than flying until the receipts are added up, because the price drivers carry in their heads is the gas, and the gas is the smallest big line on the trip. On a 1,000-mile round trip for two, the gas is $150.71, and the hotels are $300, and the food is $300, and the total is $875.71, which is $437.86 a person, $291.90 a day, and $0.88 a mile. This ledger prices the whole trip, not the tank: gas, hotels, food, tolls, and activities, split per person and per day, and then it prices the flight for the same group, so the drive-versus-fly question gets an answer in dollars instead of a feeling.

Sources: AAA national average regular gasoline $4.22 a gallon, October 29, 2026 (Energy Information Administration week of October 26: $4.269; California $6.00, North Carolina $3.46, AAA October 27, 2026); CoStar U.S. hotel average daily rate $177.65 for the week of October 11-17, 2026, and $172.38 for September 27-October 3; a November 2026 hotel-price sample of 50 cities with a median night of $152 on a Tuesday and $180 on a Saturday; General Services Administration fiscal year 2027 standard per diem $181 a day, $113 lodging plus $68 meals and incidentals, effective October 1, 2026; Bureau of Transportation Statistics second-quarter 2026 average domestic itinerary fare $445, round-trip average $549; Hopper Thanksgiving 2026 round-trip average $402, up 31 percent year over year, and Christmas $452, up 23 percent; IRS standard mileage rate 76 cents a mile for July through December 2026; EPA average new-vehicle fuel economy 28.1 miles per gallon. Model: fuel is distance divided by miles per gallon, times the gas price; lodging is nights times the nightly rate; food is days times food per person per day times travelers; the total is fuel plus lodging plus food plus tolls plus activities; flying is the flight price per person times travelers plus airport costs. This is a planning estimate, not financial advice.

Step 1 — The drive

Step 2 — The nights

Two nights at $150 a room is $300, which is 34.3 percent of the total on the defaults, tied with food as the largest line. The $150 default sits just below the November 2026 hotel-price sample median of $152 on a Tuesday, and below the CoStar national average daily rate of $177.65 for the week of October 11-17, 2026, which is what guests actually paid across hotels of every class. Roadside motels run $60 to $100 a night, mid-range hotels $100 to $150, and city hotels $180 to $300 and up, and taxes and resort fees add roughly 15 to 20 percent on top of the rate in many cities, so enter the rate with taxes if you know it. Nights are usually trip days minus one, so a three-day trip takes two nights.

Step 3 — The people

Step 4 — The extras

Tolls default to $25, which is the low end: tolls on the Northeast corridor, the I-95 run from New York to Miami, can add $150 to $200 each way in E-ZPass charges, and a transponder is typically 10 to 30 percent cheaper than paying cash. Activities default to $100 for the whole trip, which is the line that is most personal and most often forgotten: entrance fees, a tour, a round of mini-golf, and the souvenirs that were not in the plan. Set it to zero for a trip with no paid activities, and higher for a trip built around them, because a $100 activity budget is two people doing one $25 thing a day for two days, and a theme-park day alone is more than the whole default.

Step 5 — Drive versus fly

The flight default is $549 a person, the Bureau of Transportation Statistics average round-trip itinerary fare for the second quarter of 2026, and the airport costs default to $60 for the group, which covers parking or a rideshare and a bag or two. The average domestic itinerary fare, counting one-way trips, was $445 in the same quarter, and Hopper put the Thanksgiving 2026 round-trip average at $402, up 31 percent year over year, and Christmas at $452, up 23 percent. Enter the fare you were actually quoted, because the average is a national figure and your route is not: a short hop can be $150, and a holiday flight to a small airport can be $800, and the verdict flips on the difference.

The ledger

DRIVE IT

Driving wins by $282.29 on these numbers, because the flight is $549 a person and the car is one price for the whole group. Solo, the same trip flips: driving costs $725.71 against $609 to fly, so flying wins by $116.71. With four travelers, driving wins by $1,080.29. The group size is the verdict, and the flight price is the lever: at the Thanksgiving average of $402 a person, two travelers face a coin flip, flying wins by $11.71, and four travelers still drive, winning by $492.29.

The trip, line by line

What distance does to the price

Five trips on the same car, the same gas price, and the same $50-a-day food, with nights and days scaled to the distance at roughly 500 miles a day. The per-mile price falls as the trip gets longer, from $1.28 a mile on a 200-mile day trip to $0.74 on a 2,500-mile cross-country run, because the fixed lines, the tolls and the activities, are spread over more miles, and because the food and lodging grow slower than the distance. The 500-mile weekend is $550.36, the 1,000-mile trip is $875.71, and the 2,500-mile trip is $1,851.79, which sits inside the $1,500 to $3,000 range the road-trip guides give for a cross-country week.

What the car does to the price

Five cars on the same 1,000-mile trip, the same gas price, the same hotels, and the same food. A car that gets 20 miles per gallon burns $211.00 of gas and totals $936.00. A car that gets 40 burns $105.50 and totals $830.50. The difference between the thirstiest and the most frugal car on the list is $105.50, which is real money and also the smallest saving on the page, because fuel is 17.2 percent of the trip: doubling the mileage halves a line that was never the biggest one. The car matters most on long trips and least on short ones, and it matters least of all when the hotels and the food are doing the spending.

The gas price is the line drivers watch most and the line that moves the total least, which is the finding the tables keep returning. Filling up in North Carolina at $3.46 instead of California at $6.00 saves $90.71 on a 1,000-mile trip, which is real, and finding gas 30 cents cheaper saves $10.71, which is a coffee. The lines that move the total are the hotel rate and the food, which together are 68.6 percent of the trip, and the group size, which decides whether driving beats flying at all. A cheaper room at $100 instead of $150 saves $100 on the trip, a cooked dinner saves $102 over three days for two, and a third traveler turns a coin flip into a drive.
