How to calculate fuel cost for a trip

Divide the distance by your car's MPG to get the gallons you will burn, then multiply by the price per gallon. Cost per person divides that total by everyone sharing the ride.

Why your real cost may be higher

Real mileage drops with highway speeds above about 65 mph, heavy loads, roof racks and cold weather. If you track your fill-ups, use your real MPG instead of the sticker number. To see all of your driving costs and not just gas, try the car ownership cost calculator.
