Fuel Cost Calculator

Estimate fuel costs for a road trip or daily commute. Enter distance, your vehicle's fuel efficiency, and fuel price to see total cost.

How the fuel cost calculator Works

This tool uses the following formulas to compute results:

  • Fuel used = Distance / Fuel efficiency (MPG or L/100km)
  • Cost = Fuel used × Price per unit
  • For L/100km: Fuel used = (Distance × L/100km) / 100

Frequently Asked Questions

How do I find my car's fuel efficiency?

Check your owner's manual or fueleconomy.gov. Combined MPG is usually between city and highway ratings.

How is L/100km different from MPG?

L/100km measures fuel used per distance (lower is better). MPG measures distance per fuel unit (higher is better).

Does driving speed affect fuel cost?

Yes. Fuel efficiency typically peaks around 50–60 mph and drops significantly above 65 mph due to aerodynamic drag.
