Cost per km Calculator
Know your true cost per kilometer.
Cost per km = consumption × price / 100. For EVs use kWh/100km instead of L/100km.
How it works
Cost per km = consumption × price / 100. For EVs use kWh/100km instead of L/100km.
Worked example
7 L/100km × 1.80 / 100 = 0.126 per km, or 12.60 per 100 km.
