Holiday Road Trip on a Budget: How to Drive Home for Less
The short answer
Set a trip budget before you leave, with gas, food and lodging as separate lines. Then save on fuel: keep tires at the right pressure, drive at a steady speed, skip the rooftop cargo box if you can, and don't idle. [2][3]
Why so many people are driving
PwC's Holiday Outlook 2026 survey found that a third of people with holiday travel plans are skipping the plane ticket, and 35% plan to stay with friends or family instead of paying for lodging. [1]
Step 1: Build a trip budget
Give each cost its own line:
- Gas, both ways
- Food and snacks on the road
- Lodging, if you're not staying with family
- Tolls and parking
- A small cushion for surprises
To estimate gas, divide your round-trip miles by your car's miles per gallon, then multiply by the price per gallon. For example, a 600-mile round trip in a car that gets 30 mpg uses about 20 gallons. Multiply 20 by the price at your local station. Packing snacks and drinks from home keeps the food line small.
Step 2: Get the car ready
A car in good shape uses less fuel and is less likely to cost you on the road.
- Check tire pressure. Proper inflation can improve gas mileage by 0.6% on average, and up to 3% in some cases. Under-inflated tires also wear faster and are less safe. [3] Use the pressure on the sticker in the driver's door jamb or glove box, or in your owner's manual, not the maximum printed on the tire. [3]
- Don't ignore the check engine light. It can point to a problem that hurts fuel economy and leads to costly repairs later. Have it checked before a long drive. [3]
- Use the recommended motor oil grade. Using the grade your manufacturer recommends can improve gas mileage by 1% to 2%. [3]

Step 3: Drive to save gas
These habits come from fueleconomy.gov, run by the U.S. Department of Energy and EPA. [2]
- Drive smoothly. Speeding, rapid acceleration and hard braking can lower gas mileage by roughly 15% to 30% at highway speeds, and 10% to 40% in stop-and-go traffic. [2]
- Watch your speed. Gas mileage usually drops quickly above 50 mph. [2]
- Use cruise control on the highway to hold a steady speed. [2]
- Pack inside the car when you can. A large rooftop cargo box can cut fuel economy by 6% to 17% on the highway, and 10% to 25% at 65 to 75 mph. A rear-mount cargo box or tray cuts it by much less: 1% to 5% on the highway. [2]
- Lighten the load. An extra 100 pounds can reduce your MPG by about 1%. [2]
- Don't idle. Idling can burn a quarter to a half gallon of fuel per hour. Turn the engine off when you're parked. [2]
Step 4: Cut the other costs
- Stay with family or friends if that's an option. [1]
- Bring a cooler with meals for the first day.
- Plan stops ahead so you aren't buying gas or food at the most expensive exit.
