Frequently Asked Questions
How do I calculate the fuel cost of a trip?
Divide the trip distance by your vehicle's fuel efficiency to get fuel used, then multiply by the price per unit of fuel. For example, 300 miles ÷ 30 MPG = 10 gallons × $3.50 = $35.00 total fuel cost.
How much gas will my road trip use?
Enter your trip distance and your car's MPG rating (found on the window sticker or fueleconomy.gov) into the calculator. It will show you exactly how many gallons you'll burn and what it'll cost at current gas prices.
How do I split gas money fairly?
Enter the number of passengers in the 'Split between' field. The calculator divides the total fuel cost evenly, so everyone pays their fair share — no mental math required on the road.
