Estimate what fuel will cost for a trip before you set off. Enter the distance you are driving, your vehicle fuel economy, and the fuel price you pay, and the calculator works out how much fuel the trip needs and the total cost. It supports miles with miles-per-gallon and kilometers with liters-per-hundred-kilometers, so it fits how fuel economy is measured wherever you are. You can also split the total across passengers to see the cost per person, which is handy for carpools and road trips. Because you type in the current price yourself, the estimate stays accurate without needing any live fuel-price service, and nothing about your trip leaves your browser. Adjust any input to compare routes or vehicles. Everything is computed locally.
