Trip Fuel Cost Calculator

About this calculator

This calculator multiplies trip distance by a vehicle's fuel consumption rate (liters per 100 km, or the inverse of miles per gallon) and then by the fuel price to estimate total fuel needed and its cost, handling the unit conversion between L/100km and MPG systems automatically. The core relationship is fuel used = distance × (consumption/100), and cost = fuel used × price per liter or gallon.

Road-trippers and commuters budgeting for gas before a long drive, rideshare and delivery drivers estimating operating costs, and families comparing whether to drive or fly based on fuel expense all use this. Enter the trip distance, your vehicle's fuel consumption, and the local fuel price to get the estimated fuel volume and cost.
