How It Works
The calculator divides trip distance by your vehicle’s MPG to find gallons needed, then multiplies by the price per gallon for total cost, and divides cost by distance for a per-mile figure.
How to Use This Tool
- Enter the trip distance in miles.
- Enter your vehicle’s fuel economy in miles per gallon.
- Enter the current price per gallon and click Calculate.
Real-world fuel economy varies with speed, terrain, load, and driving style, so treat the result as an estimate rather than an exact figure.
Did You Know?
- Highway driving at a steady speed typically gets better MPG than stop-and-go city driving.
- Cost per mile is a handy figure for comparing a road trip’s fuel cost against a flight or other travel option.
Frequently Asked Questions
Does this account for tolls or other trip costs?
No, this only estimates fuel cost. Tolls, parking, and food would need to be added separately for a full trip budget.
What if my trip is round trip?
Enter the full round-trip distance (there and back) to get the total cost for the whole trip.
