Road Trip Cost Calculator

How this tool works

The distance entered is the complete route distance unless you select “Double for return journey.” For km/L, liters = kilometers ÷ efficiency. For L/100 km, liters = kilometers × efficiency ÷ 100. For mpg, gallons = miles ÷ efficiency, using the selected US or Imperial gallon. Fuel cost = fuel needed × price per matching unit. Add tolls, parking, vehicle costs and extras, then apply the buffer. 1 mile = 1.609344 km.
