Fuel Cost Calculator — The Smartest Way to Estimate Your Trip Fuel Cost

Whether you are planning a weekend road trip, calculating daily commute expenses, or comparing the running costs of different fuel types, a fuel cost calculator is an essential tool that saves you time and money. Our free online fuel cost calculator helps you instantly estimate how much you will spend on petrol, diesel, CNG, or electric vehicle (EV) charging for any journey — no sign-up required, and it works on every device.

How Does a Trip Fuel Cost Calculator Work?

A trip fuel cost calculator uses three simple inputs to estimate your total fuel expense: the distance of your trip, your vehicle's fuel efficiency (measured in km/L, MPG, or km/kg for CNG), and the current fuel price per litre or gallon. The formula is straightforward — divide the total distance by your vehicle's mileage to find the litres (or gallons) of fuel needed, then multiply by the price per unit. The result is your estimated trip fuel cost. For electric vehicles, the calculator divides your trip distance by the vehicle's full-charge range and multiplies the number of charges needed by the cost per charge.

Our fuel cost calculator goes further — it also shows you the cost per kilometre (or per mile), projects your annual commute expense, and lets you split the total among passengers for carpooling. You can switch between km and miles, choose from 50+ world currencies, and compare four fuel types side by side in the comparison matrix above.

Electric Vehicle (EV)
Charges Needed = ceil(Distance / Range)
Total Cost = Charges × Cost Per Charge

Example: 600 km with 300 km range = 2 full charges. At ₹250/charge = ₹500.
