Calculate your vehicle's MPG, fuel costs per trip, and annual fuel expenses instantly.
Quick Answer:Gas mileage (MPG) = Miles Driven / Gallons Used. The average car in 2026 gets about 25 MPG. If gas costs $3.50/gallon, that's $0.14 per mile. A car getting 35 MPG saves about $700/year over a 25 MPG car at 12,000 annual miles.

In 2026, with average gas prices around $3.50/gallon, fuel efficiency matters more than ever. Improving your MPG by just 5 points (e.g., from 25 to 30 MPG) saves roughly $280/year at 12,000 miles. Hypermiling techniques like coasting to stops, maintaining steady highway speeds of 55-60 mph, and keeping tires inflated to spec can improve real-world MPG by 10-15% over aggressive driving styles.
A good gas mileage depends on the vehicle type. For 2026, the average new car gets about 25-30 MPG combined. Compact cars typically achieve 30-40 MPG, hybrids 45-55 MPG, and full-size trucks 15-22 MPG. An MPG above 30 is generally considered good for a non-hybrid vehicle.
To calculate gas mileage, fill your tank completely, reset your trip odometer, drive until you need fuel again, fill up again and note the gallons used. Then divide the miles driven by the gallons used. For example, if you drove 300 miles and used 12 gallons, your MPG is 300/12 = 25 MPG.
You can improve gas mileage by maintaining proper tire pressure, driving at steady speeds, avoiding rapid acceleration and hard braking, removing excess weight from the vehicle, using cruise control on highways, keeping up with regular maintenance such as air filter and oil changes, and reducing idling time.
