About the Fuel Cost Calculator

Planning a road trip or working out your monthly commute cost? The AlarmDaddy Fuel Cost Calculator turns distance, your vehicle's mileage, and the current fuel price into a clear rupee figure. It works for petrol, diesel, or CNG, and can estimate a one-way trip, a round trip, or a monthly commute.

Enter the trip distance, your vehicle's mileage (kilometres per litre), and the current fuel price per litre. The calculator returns the litres needed and the total fuel cost. Toggle round-trip to double it, or enter your daily commute and working days to project a monthly fuel budget. It is the quickest way to compare the running cost of two vehicles or to split fuel money fairly on a shared trip.

How to use this calculator

  1. 1Enter the trip distance in kilometres.
  2. 2Enter your vehicle's mileage (km per litre).
  3. 3Enter the current fuel price per litre.
  4. 4Toggle round trip or enter working days for a monthly estimate.
  5. 5Read the litres needed and total fuel cost.

The formula

Fuel needed = distance / mileage; Cost = fuel needed × price per litre.

Distance divided by mileage gives the litres of fuel required. Multiplying by the price per litre gives the trip cost. For a round trip the distance is doubled; for a monthly estimate the daily distance is multiplied by working days.
