Road Trip Fuel Planner Calculator

Road Trip Fuel Planner

Plan fuel stops and total fuel costs for a road trip based on distance, vehicle efficiency, and tank size.

Formula

Total Gallons = Distance / MPG; Total Fuel Cost = Total Gallons x Gas Price; Stops = ceil(Distance / Usable Range) - 1

Frequently Asked Questions

How do I calculate fuel cost for a road trip?
Divide total distance by your vehicle MPG to get gallons needed, then multiply by the average gas price along your route.
How often should I stop for gas on a road trip?
Plan stops when your tank reaches about a quarter full. In remote areas, fill up whenever possible as stations may be far apart.
Does highway driving use more or less fuel?
Most vehicles are most efficient at 45 to 65 mph. Highway driving at moderate speeds is typically more fuel efficient than city driving, but speeds above 65 mph reduce efficiency.
