How it works

Divide the distance by your car's miles per gallon to get gallons used, then multiply by the price per gallon.

Formula

Cost = (miles ÷ MPG) × price per gallon

Example

350 miles at 28 MPG with gas at $3.45 costs about $43.13.

Assumptions & limitations

  • Real fuel economy varies with speed, load, weather and driving style.

Frequently asked questions

How do I find my MPG?
