About this calculator

A fuel cost calculator computes the total fuel expense for a journey based on distance, vehicle fuel efficiency (km per litre or L/100km), and current fuel price. It is useful for trip budgets, vehicle cost comparisons, and checking the savings from better fuel efficiency.

Fuel efficiency varies by vehicle type: economy cars average 15–20 km/L, SUVs 8–12 km/L, and trucks 5–8 km/L. Electric vehicles do not have fuel cost, but they do have electricity cost.

Common uses

  • Calculate fuel budget for a road trip
  • Compare the annual fuel cost of two different vehicles
  • See how much fuel price changes affect your monthly costs
  • Calculate cost per km for different vehicles

Frequently asked questions

What is the fuel cost formula?

Fuel Cost = (Distance / Fuel Efficiency) × Fuel Price. For example, a 500 km trip in a car that gets 15 km/L with fuel at ₹100/L: Fuel = 500/15 = 33.33 litres. Cost = 33.33 × ₹100 = ₹3,333.
