A 7-day road trip in the United States costs between $500 and $3,000 per person depending almost entirely on two variables: where you sleep and how you eat. Gas is actually the smallest controllable expense. Accommodation and food together account for 70-80% of total trip cost.
The budget version: camp for free on BLM land, cook your own food, and drive a fuel-efficient car. Total: $50-80/day per person. The comfortable version: budget motels, one restaurant meal per day, and mix camping with hotels. Total: $100-150/day per person. Both versions see the exact same scenery.
This guide gives you specific dollar amounts and specific strategies for each category. Use our Route Builder to calculate exact fuel costs for your vehicle on any route.
Real math, not estimates. Based on $3.50/gallon national average (2026). Your route may vary by $0.50-1.00/gallon depending on state.
The most common road trip setup. At $3.50/gal national average, a week-long trip runs $400 in gas.
SUVs cost 38% more in fuel than sedans. If you are renting, the sedan saves $150+ per week in gas alone.
EVs are the cheapest per-mile option, but DC fast charging rates vary. Electrify America averages $0.26/kWh; Tesla Superchargers are similar.
Families often drive fewer daily miles with more stops. Budget $50-60/day for fuel in a minivan.

340 million acres of public land in the western US, most of it open for dispersed camping. No reservations, no fees, no amenities. You need: water, a shovel for waste, and the ability to navigate dirt roads. Best areas: Utah, Nevada, Arizona, Colorado, Montana.
193 million acres of national forest land. Camp anywhere unless posted otherwise, typically 100 feet from water and roads. 14-day limit at most locations. Use the MVUM (Motor Vehicle Use Map) for each forest to find legal roads.
Many Walmart locations allow overnight parking. Call ahead. This is not camping, it is sleeping in your car with access to bathrooms and supplies at 6 AM. Perfectly fine for one-night stopovers between destinations. Use the iOverlander app to check specific locations.
Legal for overnight stays in most states. Time limits vary (typically 8-12 hours). Well-lit, patrolled, with bathrooms. Not glamorous, but free, safe, and everywhere. Check state-specific laws before relying on this.
Many casinos allow free overnight RV and car parking. They want you inside gambling, but there is no obligation. Clean bathrooms, 24-hour security, often near restaurants. A genuine budget hack in casino states.
Hipcamp connects you to private landowners offering camping for $10-30/night. Harvest Hosts ($99/year) gives free overnight stays at wineries, breweries, and farms, with an expectation of a purchase. Both are better than random campgrounds.
The goal is not to eat badly. It is to eat well for less. Here is how to spend $20-30/day on food instead of $50-75. See also: best road trip snacks.
Skip the myths (premium gas does nothing in a regular car). These are physics-based savings you can measure.
The best road trip experiences do not cost money. Nature, scenery, and small-town exploration are free everywhere.

Private rooms available at many locations for $50-80. Not just for 20-year-old backpackers. Clean, social, and a fraction of hotel costs. Best hostel cities: San Francisco, Chicago, New York, San Diego, Portland.
Reservable on Recreation.gov or individual state park websites. Usually include water, bathrooms, and picnic tables. Book 1-3 months in advance for summer weekends. Midweek is almost always available.
Not glamorous. Perfectly functional. A bed, a bathroom, AC, WiFi. Motel 6 still averages under $60 in rural areas. Book directly on their app for the lowest rates, not through Expedia or Booking.com.
Still active despite being less popular than its peak. Read reviews carefully, message multiple hosts, and trust your judgment. Best for solo travelers in cities. Not practical with families or in rural areas.
Las Vegas off-strip hotels, Reno, Biloxi, and Atlantic City regularly have rooms under $50. They make money on gambling and food, not rooms. Midweek rates can be absurdly cheap.
HotelTonight (now part of Airbnb) and Priceline Express Deals offer same-day discounts of 30-50%. Works best if you are flexible about exactly which hotel you get. Best savings are Tuesday-Thursday nights.
Travel 2-4 weeks outside peak season. Same destination, 30-50% cheaper, and often better weather and fewer crowds.
Money ruins road trip friendships faster than bad music choices. Set rules before departure, not during.
Splitwise app. Log every fill-up. Settle at the end. The driver should NOT pay more just because they drive. They are providing the car.
Savings math: With 4 people in a sedan, gas drops from $58/day per person to $14.50/day per person. This is where groups save the most.
Split evenly by person, not by room. If one person snores and needs their own room, they pay their share plus the solo premium.
Savings math: A $120 Airbnb with 3 people is $40 each. The same Airbnb for a couple is $60 each. Groups of 3-4 hit the sweet spot.
One shared pool for groceries ($20/person/day), individual tabs for restaurant meals. The shared pool avoids nickel-and-diming over who ate the last banana.
Savings math: The grocery pool method eliminates 90% of food-related arguments. Top it up when it runs low. Even contributions.
Pay individually for what you do. If 2 of 4 people want to kayak, the kayakers pay. Do not guilt non-participants into splitting.
Savings math: Group trips fail when everyone is forced into the same activities. Budget for individual choices. It preserves friendships.
