Fuel Cost Calculator

Calculate trip fuel cost from distance, consumption (L/100km or MPG) and fuel price.

How to Calculate Fuel Cost for Any Trip

Planning a road trip or daily commute? Knowing the fuel cost in advance helps you budget accurately and compare driving costs against alternative transportation options like trains or flights. Fuel expenses depend on three main factors: the distance you travel, your vehicle's fuel consumption rate, and the current price of fuel in your area.

Our fuel cost calculator supports both metric (liters per 100 km) and imperial (miles per gallon) measurement systems. Enter your trip distance, your vehicle's fuel consumption, and the local fuel price, and the calculator instantly shows you how much fuel you will use and what the trip will cost. The round-trip option doubles the distance automatically for return journeys.

This tool is valuable for comparing the cost-effectiveness of different vehicles, planning vacation budgets, calculating business mileage expenses, or deciding whether to drive or take public transportation. By experimenting with different fuel consumption rates, you can also estimate how much you would save by switching to a more fuel-efficient vehicle or a hybrid/electric car.

FAQ

How do I calculate fuel cost per kilometer?+
Multiply your fuel consumption (L/100km) by the price per liter, then divide by 100. For example, if your car uses 7 L/100km and fuel costs $1.80/liter: (7 x 1.80) / 100 = $0.126 per km.
How do I convert MPG to L/100km?+
Divide 235.214 by the MPG value. For example, 30 MPG = 235.214 / 30 = 7.84 L/100km. This works for US gallons; for UK (imperial) gallons, divide 282.481 by the MPG value.
What is the average fuel consumption for a car?+
A typical modern car uses 6-9 L/100km (26-39 MPG). SUVs average 8-12 L/100km (20-29 MPG). Hybrid vehicles achieve 3-5 L/100km (47-78 MPG). Small city cars can be as efficient as 4-6 L/100km.
Is it cheaper to drive or fly for long trips?+
For solo travelers on trips over 300-400 km, flying is often cheaper when accounting for fuel, tolls, and vehicle wear. However, driving becomes more economical with 2+ passengers sharing costs, and offers flexibility and door-to-door convenience.
How can I reduce my fuel consumption?+
Maintain steady speeds, avoid aggressive acceleration, keep tires properly inflated, remove roof racks when not in use, avoid excessive idling, use cruise control on highways, and service your vehicle regularly. These habits can reduce fuel consumption by 10-25%.
