How do I calculate the fuel cost of a trip?
Enter the trip distance, your vehicle's fuel consumption (in L/100km, km/L, or MPG) and the fuel price — the calculator instantly shows how much fuel you'll use and the total cost.
How do I find my car's actual fuel consumption?
Use the "Calculate Consumption from Fill-up" section: enter the distance driven since your last full tank and how much fuel you added, and it shows your real consumption in every common unit.
