How it works
Enter the trip distance, your vehicle's fuel efficiency, and the price per gallon to estimate total fuel cost. Check your vehicle's actual combined MPG rating (or your own tracked average) for the most accurate estimate — city and highway driving affect real-world efficiency.
Formula
Gallons used = Distance ÷ MPG Total cost = Gallons used × Price per gallon
Example
A 300-mile trip at 30 MPG with gas at $3.50/gallon: gallons used = 300 ÷ 30 = 10, total cost = 10 × $3.50 = $35.00.
Frequently asked questions
Where do I find my car's MPG?
Check your vehicle's window sticker, owner's manual, or the EPA's fueleconomy.gov — or use your own tracked average from recent fill-ups for a more personalized estimate.
Does this account for city vs. highway driving?
Not directly — enter the MPG figure that best matches your trip (city, highway, or combined) for a more accurate result.
