How it works
Annual cost = miles ÷ MPG × price; savings = difference between the two carsFrequently Asked Questions
How much can a more efficient car save?
Going from 25 to 40 MPG over 12,000 miles a year at $4/gallon saves about $720 annually — $3,600 over five years. The gain is largest for high-mileage drivers and expensive fuel.
Why compare in cost per year, not MPG?
MPG differences are deceptive: improving from 15 to 20 MPG saves more fuel than 40 to 50 MPG, because low-MPG cars burn so much more. Dollars per year cuts through the illusion.
Is it worth paying more for better mileage?
Compare the price premium against the multi-year savings shown here. A $2,000 premium that saves $700/year pays back in under three years and profits after — but only if you keep the car that long.
