Project a full year of fuel spending from mileage and MPG.
Annual fuel spend is the total miles divided by economy and multiplied by the fuel price, with a per-100-mile figure normalized for comparison. Two cars with a 3 MPG difference can differ by hundreds of dollars a year for a heavy commuter, so this baseline matters when choosing.
Annual Fuel Cost
Annual = miles / MPG x price; per 100 miles = price / MPG x 100
Annual = miles / MPG x price; per 100 miles = price / MPG x 100 Annual fuel spend is the total miles divided by economy and multiplied by the fuel price, with a per-100-mile figure normalized for comparison.

This calculator takes 3 inputs: Miles per year, Vehicle MPG, Fuel price. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
