Calculate the fuel cost for a trip and your annual fuel expenses based on distance, fuel efficiency, and gas prices.
Fuel Cost Formulas:
Gallons Used = Distance / MPG
Trip Cost = Gallons Used x Price per Gallon
Annual Cost = (Annual Miles / MPG) x Price per Gallon
Divide the trip distance by your car's fuel economy (MPG). Then multiply the gallons used by the current price per gallon. For example: 300 miles / 30 MPG = 10 gallons x $3.50 = $35.
The average fuel economy for new passenger cars in the US is around 28-32 MPG. SUVs average 22-26 MPG, while trucks average 18-22 MPG. Hybrids can achieve 45-55 MPG.
The average American household spends approximately $2,000-$3,000 per year on gasoline, depending on local gas prices, miles driven, and vehicle fuel economy.
City MPG is lower because of stop-and-go traffic, idling, and frequent acceleration. Highway MPG is higher due to steady speeds. The EPA combined rating is a weighted average of 55% city and 45% highway driving.
Maintain proper tire pressure, keep up with oil changes, avoid aggressive acceleration and braking, remove excess weight from the vehicle, and use cruise control on the highway.
Most vehicles achieve peak fuel economy between 45-55 mph. Above 60 mph, aerodynamic drag increases significantly and fuel economy drops. At 75 mph, you may use 15-20% more fuel than at 55 mph.
