Plan the full road trip cost before you leave
The calculator estimates total distance, gas or fuel needed, fuel cost, tolls, additional expenses, and each traveler’s share. It supports kilometers and miles, including MPG for US drivers. Actual fuel use can vary with speed, traffic, load, weather, and vehicle condition.
How to calculate fuel or gas cost for a road trip
For L/100 km, multiply total kilometers by consumption and divide by 100. For km/L, divide kilometers by fuel economy. For MPG, divide total miles by miles per gallon to get US gallons. Multiply the fuel quantity by the price per liter or gallon, then add tolls and other expenses.
One way or round trip
Enter a single-leg distance and choose the trip type. Cuantalia handles the total distance automatically.
