Estimate how much gas your trip will cost and how much each passenger should chip in.
The formula
Fuel cost = miles ÷ MPG × price per gallon. A 240-mile trip each way (480 miles) in a car that gets 28 MPG uses about 17.1 gallons. At $3.29 a gallon that is $56.40, or $14.10 each for four people.
Tips to spend less on gas
- Keep tires properly inflated; low pressure can cost 1–3% in fuel economy.
- Drive at 60–65 mph instead of 75–80 on the highway.
- Remove roof racks you are not using.
- Compare gas prices along the route with a gas price app.
