Fuel Cost Calculator
Estimate what a drive will cost in gas. Enter the trip distance, your vehicle's fuel economy, and the current price per gallon.
How it's calculated
Gallons needed = distance ÷ MPG, and cost = gallons × price per gallon. We also show the cost per mile so you can compare routes or vehicles.
Frequently asked questions
How do I calculate the gas cost of a trip?
Divide the trip distance by your car's MPG to get gallons, then multiply by the price per gallon.
Does driving style affect fuel cost?
Yes — hard acceleration, high speeds, and idling lower your MPG and raise the cost. Steady highway driving is most efficient.
