Calculate the fuel needed and total petrol or diesel cost of any trip from distance, mileage and fuel price, then split the cost between passengers.
The Fuel Cost Calculator works out how much fuel a trip will need and its total cost, based on the distance, your vehicle's fuel efficiency and the current price per litre, and can split that cost evenly between passengers for a shared journey. Enter the trip details and it calculates fuel required as distance divided by kilometres per litre, then multiplies by the fuel price for the total.
It's useful for planning any road trip, commute or delivery run where you want to know the fuel cost in advance, whether that's for personal budgeting, agreeing a fair fuel-cost split with travel companions, or comparing the running cost of different vehicles. A round-trip toggle automatically doubles the distance for return journeys.
Using your actual trip distance, vehicle efficiency and current local fuel price produces a realistic cost estimate rather than a rough average that ignores your specific vehicle or route.
Toggling round trip on doubles the distance calculation automatically, avoiding the need to manually re-enter or double the distance figure yourself for a return journey.
Entering the number of passengers immediately shows each person's fair share of the total fuel cost, which is handy for agreeing a contribution before setting off on a shared trip.
Fuel needed is calculated as distance divided by kilometres per litre, and total cost is that fuel amount multiplied by the price per litre. Turning on the round-trip toggle simply doubles the distance figure before this calculation runs, so the outbound and return legs are both accounted for automatically.
The most reliable method is the odometer trip test: fill the tank completely, reset the trip counter, drive normally, then refill and divide the kilometres driven by the litres needed to top up again. City driving efficiency is typically 15–25% lower than highway driving due to more frequent stopping and idling.
Dividing the total fuel cost evenly by the number of passengers is the simplest approach for a shared trip, though some groups prefer to exclude the driver from the split since they're providing the vehicle — the calculator gives the even-split figure as a starting point for that conversation.
Fuel needed = distance ÷ kilometres per litre, and total cost = fuel needed × price per litre. Turn on round trip to double the distance automatically.
Check the odometer trip method: fill the tank, drive, refill and divide the kilometres driven by the litres added. City mileage is usually 15–25% lower than highway mileage.
