Calculate your MPG, monthly fuel costs, and cost per mile. See exactly how much you spend on gas.
To calculate your car's MPG, fill your tank completely, reset your trip odometer, drive normally, then fill up again. Divide the miles driven by the gallons used to fill up. For example, if you drove 350 miles and used 11.5 gallons, your MPG is 350/11.5 = 30.4 MPG. Repeat this calculation several times to get an accurate average.
Fuel costs are one of the biggest variable expenses for most households. The average American drives about 15,000 miles per year. At 30 MPG and $3.50/gallon, that is about $1,750 per year in gas. Improving your MPG by just 5 miles per gallon — from 25 to 30 MPG — saves about $350 per year at the same price and mileage.
