How much does a 500-mile road trip cost?

On the same defaults, $550.36 for two travelers: $75.36 in gas, $150 for one hotel night, $200 in food over two days, $25 in tolls, and $100 in activities. That is $275.18 a person and $1.10 a mile.

How much does a cross-country road trip cost?

A 2,500-mile trip for two costs $1,851.79 on the defaults in this calculator: $376.79 in gas, $750 for five hotel nights, $600 in food over six days, $25 in tolls, and $100 in activities. Published guides put the same trip at $1,500 to $3,000 and more.

Why do road trips cost more than expected?

Because the line drivers carry in their heads is the gas, and the gas is 17.2 percent of the trip. Hotels and food together are 68.6 percent. A 1,200-mile trip that looks like $150 in gas becomes $1,050 once the accommodation and meals are included.

The short answer, worked on real numbers

Take a 1,000-mile round trip for two people, in a car that gets 28 miles per gallon, at the national average gas price of $4.22 a gallon, with two hotel nights at $150 a room, three days of food at $50 a person a day, $25 in tolls, and $100 in activities. The total is $875.71. It is made of five lines: fuel $150.71 for 35.71 gallons, lodging $300, food $300, tolls $25, and activities $100. That is $437.86 a person, $291.90 a day, and $0.88 a mile, and the per-person figure is the one to carry into the comparison with flying, because the flight is priced per person and the car is priced per trip. The same trip for one person is $725.71, and for four people it is $1,175.71, which is $293.93 a person, because the fuel, the room, the tolls, and the activities do not grow with the group, and only the food does.

Those numbers are worth checking against the published guides, because the guides agree with them in a way that should reassure a planner and worry one at the same time. A road-trip guide puts a 1,000-mile vacation at $500 to $1,000 and more, and this calculator's $875.71 sits inside that range, near the top of it, because the range assumes cheaper hotels and cheaper food than the defaults here. The same guide puts a 500-mile weekend trip at $200 to $400 including one night of lodging, and this calculator's 500-mile figure is $550.36, which is above the range, because the calculator counts $200 of food for two people over two days and $100 of activities that the guide's range does not. The cross-country figure is the cleanest agreement: the guide puts a 2,500-mile trip at $1,500 to $3,000 and more, and this calculator's $1,851.79 sits comfortably inside it. A second calculator's worked example is the sharpest check of all: a 1,200-mile trip at 28 miles per gallon and $3.50 gas, three hotel nights at $130, four days of food at $60 a person a day for two travelers, and $30 in tolls, which that calculator totals at $1,050, and which this calculator reproduces line for line, fuel $150.00, hotels $390, food $480, tolls $30, total $1,050. The model is the same model, and the agreement is exact, which is the point of a calculator: the same inputs should give the same answer, whoever does the arithmetic.

Why the answer is never just the gas

The reason a road trip costs more than drivers expect is not that any one line is hidden. It is that the line drivers carry in their heads is the gas, and the gas is the smallest big line on the trip. On the defaults in this calculator, fuel is $150.71, which is 17.2 percent of the $875.71 total, and lodging is $300, which is 34.3 percent, and food is $300, which is also 34.3 percent. The hotels and the food together are 68.6 percent of the trip, which is four times the gas, and the driver who budgets $150 for gas and $200 for everything else is short by more than $500 before the first night. The comparison with a second calculator makes the point in a different way: a 1,200-mile trip that looks like $150 in gas becomes $1,050 once the accommodation and the meals are included, and the gas is 14.3 percent of that total, which is the same shape as this calculator's 17.2 percent. The trip is not a gas purchase with a hotel attached. It is a hotel and food purchase with a gas line attached, and the budget that starts with the gas is a budget that starts with the wrong line.

The second mechanism is the per-day framing, which is how the trip is actually experienced and how it should be budgeted. The total of $875.71 is $291.90 a day over three days, and the per-day figure is the one that survives contact with the trip, because the trip is lived one day at a time and the money is spent one day at a time. The per-day figure is also the one that makes the comparison with flying honest: a flight is a single purchase, and a road trip is three days of purchases, and the $291.90 a day is the rate at which the trip burns money, which is the number to compare with the daily rate of any other way of spending the same three days. The per-mile figure of $0.88 is the number for comparing trips of different lengths, and it is the number that falls as the trip gets longer, which is the subject of the ladder below, and which is the reason a longer trip is cheaper per mile and more expensive in total, which is the trade that every road trip is.

The distance ladder

Distance	Nights / days	Fuel	Total	Per person	Per mile
200 mi	0 / 1	$30.14	$255.14	$127.57	$1.28
500 mi	1 / 2	$75.36	$550.36	$275.18	$1.10
1,000 mi	2 / 3	$150.71	$875.71	$437.86	$0.88
1,500 mi	3 / 4	$226.07	$1,201.07	$600.54	$0.80
2,500 mi	5 / 6	$376.79	$1,851.79	$925.89	$0.74

The ladder scales nights and days with the distance, at roughly 500 miles of driving a day, so a 200-mile trip is a day trip with no hotel, a 500-mile trip takes one night, and a 2,500-mile trip takes five nights and six days. The per-mile price falls as the trip gets longer, from $1.28 a mile on the day trip to $0.74 on the cross-country run, because the fixed lines, the $25 of tolls and the $100 of activities, are spread over more miles, and because the food and lodging grow slower than the distance. The total rises all the way, from $255.14 to $1,851.79, which is the point the ladder exists to make: a longer trip is cheaper per mile and more expensive in total, and the per-mile figure is the number for comparing trips, while the total is the number for paying for one. The 200-mile day trip is the most expensive per mile and the cheapest in total, which is why a day trip feels cheap and a cross-country trip feels expensive, and both feelings are right, about different numbers.

Read the ladder against the group size, and the per-person column tells the second story. The 1,000-mile trip is $437.86 a person for two travelers, and $875.71 for one, and $293.93 for four, because the fuel, the room, the tolls, and the activities are fixed and only the food grows with the group. The per-person price falls fastest between one and two travelers, from $875.71 to $437.86, which is a halving, and it falls slowest between three and four, from $341.90 to $293.93, which is $47.97. The first extra traveler is the cheapest saving on the trip, and the fourth is still worth $47.97 a person, which is the price of a dinner. The ladder is priced for two travelers, and the calculator on this site re-prices it for any group, which is the comparison that decides whether the trip is affordable, because the trip is affordable per person, not in total, and the total is the number that scares people away from a trip they could afford.

The new insight

The gas is the line drivers watch most and the line that moves the total least, and the proof is in the shares: fuel is 17.2 percent of the trip, and lodging and food together are 68.6 percent, which means a driver who finds gas 30 cents cheaper saves $10.71 on a 1,000-mile trip, while a driver who finds a room $50 cheaper saves $100, and a driver who cooks one dinner instead of eating out saves $102 over three days for two. The gas price is the number on the sign by the highway, and it is the number that changes every day, and it is the number that matters least, because it is the smallest big line. The lines that matter are the ones that do not change every day, the room and the meals, and the driver who budgets those first and the gas second has a budget that survives the trip, while the driver who budgets the gas first has a budget that survives the first fill-up and nothing after it.

What the total leaves out, and what to do about it

The total leaves out wear on the car beyond the fuel, which the IRS prices at 76 cents a mile for July through December 2026, or $760 on a 1,000-mile trip against $150.71 of fuel alone, which means $609.29 of the car's cost is depreciation, tires, maintenance, and insurance, and none of it appears in the fuel line. It leaves out the rental car if the trip is not in the driver's own car, which is a daily rate plus the fuel, and which the calculator does not price because the rate varies by city and season. It leaves out parking at the destination, which is free in a small town and $50 a night in a city garage, and it leaves out the value of the driver's time, which the commute calculator on this site prices at the driver's wage, and which on a 1,000-mile trip is roughly 15 hours of driving, or $450 at $30 an hour, which is more than half the cash total. The practical move is to run the calculator three times: once with the numbers as planned, once with the hotel rate $50 higher, and once with the food $20 higher, and to compare the three totals, which on the defaults are $875.71, $975.71, and $995.71. The gap between the first and the third is $120, which is the price of being wrong about the two lines that matter most, and which is the contingency the trip should carry.
