About the Fuel Cost Calculator
The Fuel Cost Calculator estimates the fuel cost of a trip or a year of driving from distance, vehicle MPG, and fuel price.
Calculation method
Cost = Distance ÷ MPG × Price per gallon.
Cost = (Miles / MPG) × PriceHow to use this calculator
- Enter the total distance in miles.
- Enter your vehicle's MPG (combined city/highway).
- Enter the current fuel price per gallon.
Example
A 1,200-mile trip in a 28-MPG vehicle at $3.50/gallon uses about 43 gallons and costs $150 in fuel.
Frequently asked questions
Should I use city or highway MPG?
For a long highway trip use highway MPG; for daily commuting use combined or city MPG. The EPA sticker lists all three.
How much does driving speed affect fuel cost?
Fuel economy drops sharply above 55–60 mph. Every 5 mph above 60 costs roughly 7% in MPG.
Do EVs have equivalent fuel cost?
Yes — divide miles by MPGe and multiply by electricity price per kWh (÷ 33.7 kWh per gallon equivalent). EVs typically cost half as much per mile as gasoline.
