Fuel Consumption Formula: Your Miles Per Gallon can be calculated by dividing the number of miles you get in one tank of fuel / the number of gallons of gas you need to fill up that tank.

To determine how much you spend on gas, divide you miles per day (or month, or year) by your MPG and then multiply by the cost per gallon.
