Gas Mileage Calculator: How to Calculate MPG and Fuel Economy

Gas Mileage Calculator: How to Calculate MPG and Fuel Economy To calculate MPG (miles per gallon), divide the miles driven by the gallons of gas used. If you drove 300 miles and used 10 gallons, your car gets 30 MPG. Track this over multiple fill-ups for an accurate picture of your true fuel economy. Tracking MPG on a 2020 Accord over 18 months and 22,000 miles shows how EPA ratings hold up against real-world driving: an EPA-rated 33 MPG combined actually averaged 29.4 MPG in real-world driving — 11% below the sticker. Checking tire pressure weekly and easing off the gas pedal brought it up to 31.2 MPG, saving roughly $180 a year at current gas prices.
