Fuel Cost Calculator

Calculate the total fuel cost for your trip based on fuel price, vehicle mileage, and travel distance. Supports km/l, mpg, and L/100km.

How Fuel Cost Calculator Works

This calculator estimates fuel cost by using your vehicle’s fuel efficiency and the distance you plan to travel. It supports three mileage formats:

  • km/l — common in India & Asia
  • mpg — miles per gallon (US)
  • L/100km — common in Europe

Formula Used

Fuel Needed = Distance ÷ Efficiency (km/l)
Fuel Cost = Fuel Needed × Fuel Price

For mpg:
  Convert mpg → km/l:
  1 mpg = 0.425144 km/l

For L/100km:
  km/l = 100 ÷ (L/100km)
        

Example Calculation

If fuel price is $1.20 per liter, your mileage is 15 km/l, and your trip is 120 km:

Fuel Needed = 120 ÷ 15 = 8 liters
Total Cost = 8 × $1.20 = $9.60
Cost Per km = $9.60 ÷ 120 = $0.08
        

What Affects Fuel Cost?

  • Driving speed & style
  • Vehicle load
  • Tire pressure
  • Fuel type
  • Engine condition

Frequently Asked Questions

Both measure the same thing; they just use different unit systems.
Yes, using AC can reduce fuel efficiency by 10–25% depending on the vehicle.
Maintain steady speed, check tire pressure, avoid idling, and service your vehicle regularly.
