About This Calculator

This fuel cost calculator helps you estimate the cost of gas for your trip based on distance, your vehicle's fuel efficiency, and current gas prices.

Formula: Fuel Cost = (Distance ÷ Fuel Efficiency) × Fuel Price

For most accurate results, use your vehicle's actual fuel economy from recent fill-ups rather than the EPA estimate, as real-world mileage varies based on driving conditions.
