MPG Calculator
Your real miles-per-gallon
Find your car's real-world fuel economy. Enter the miles driven on a tank and the gallons it took to refill.
How to measure MPG
Fill up, reset your trip meter, drive, then refill. Miles driven ÷ gallons added = MPG. Doing this over a few tanks gives a more reliable average than the dashboard estimate.
Frequently asked questions
How do I calculate MPG?
Divide the miles driven since your last fill-up by the number of gallons it took to fill back up.
Why is my real MPG lower than the sticker?
City driving, cold weather, short trips, cargo and aggressive driving all reduce real-world economy.
