Fuel Cost Calculator
Estimate fuel expenses for your trip.
How does the fuel cost calculator work?
The fuel cost calculator uses three simple inputs to estimate your trip expenses: distance traveled in kilometers, vehicle fuel consumption in liters per 100 km, and the current fuel price per liter. It first calculates the total liters needed (Distance × Consumption ÷ 100), then multiplies by the fuel price. The result is the exact cost of fuel for your journey — perfect for road trip budgeting, commuting calculations, or comparing the running costs of different vehicles.
How to use the Fuel Cost Calculator
Enter the total distance of your trip in kilometers, your vehicle's average fuel consumption (check your dashboard or owner's manual — typically between 4 and 12 L/100km), and the current price of fuel per liter at your local station. Click "Calculate" to instantly see the total fuel cost.
Example calculation
A 500 km trip with a fuel consumption of 7 L/100km and a fuel price of $1.50 per liter: Total fuel needed = 500 × 7 ÷ 100 = 35 liters. Total cost = 35 × $1.50 = $52.50. The calculator performs this math instantly for any combination of values.
Frequently Asked Questions
How do I find my car's fuel consumption?
Check your vehicle's trip computer, the manufacturer specifications, or calculate it manually: fill the tank completely, reset the odometer, drive until nearly empty, then divide the kilometers driven by the liters needed to refill. This gives your real-world consumption rate.
Does this calculator work for electric vehicles?
This version is designed for liquid fuel. For electric cars, replace L/100km with kWh/100km and fuel price with electricity cost per kWh. The math is the same — the calculator still works if you treat "liters" as kilowatt-hours.
