Fuel Cost Calculator
Estimate the fuel cost of a trip or the total annual fuel bill for a vehicle.
Inputs
How it works
Gallons needed = distance ÷ MPG. Multiply by fuel price to get cost. Annual cost uses your yearly mileage estimate.
Frequently asked questions
How is trip cost calculated?
Trip cost = (distance ÷ MPG) × price per gallon.
How can I lower fuel cost?
Drive at highway speeds under 65 mph, keep tires inflated, remove roof racks, and avoid aggressive acceleration.
Does gas quality matter?
Top-tier gas has more detergents but the same energy content. Only use premium if your engine requires it.
How much do I actually spend per year?
Use the 'Annual miles' field. US average is 12,000–15,000 miles/year.
How does this compare to an EV?
EVs cost ~$0.04–0.05 per mile in electricity vs $0.12–0.15 per mile for gas at $3.50/gal and 28 MPG.
