This calculator requires the use of Javascript enabled and capable browsers. It is to determine the fuel mileage of a vehicle, based on miles driven and gallons of fuel used, and optionally, the direct fuel expense per mile, whatever the fuel is, measured in gallons. All entries should be numeric. The current odometer reading MUST be greater than the previous odometer reading. The calculator assumes that the tank was full when you recorded the Previous Odometer reading. If you know the exact number of miles since the last fill, you can enter it direct in the Trip Odometer field instead of Current and Previous data entries. The cost per gallon is the pump price you pay for a gallon of fuel. The answer is returned as a number of miles per gallon, miles since your last fill, based on your entries, and optionally, the direct fuel expense per mile and your approximate cost for the current fill.
