Enter the trip distance, your car's fuel economy and the fuel price, in whichever units you use. The calculator shows the fuel needed, the total cost and each passenger's share.
Calculated on your device. Nothing is uploaded to a server.
The calculator converts your fuel economy to liters per 100 km and multiplies by the distance to get the fuel needed. It then multiplies the fuel by the price per liter. Units are converted internally: a US gallon is 3.785 liters, a UK (imperial) gallon is 4.546 liters, and 1 US mpg equals 235.2 divided by the L/100 km figure. Highway driving is usually more efficient than a car's combined rating, but roof boxes, heavy loads, hills, air conditioning and high speeds can use 10 to 25% more fuel. Add a margin for a conservative budget.
Most cars are most efficient at about 50 to 60 mph (80 to 100 km/h). Fuel use rises sharply above that because of air resistance.
Some groups also share wear and tear. The US IRS mileage rate, which includes depreciation, is much higher than fuel alone.
Divide 235.2 by US mpg (or 282.5 by UK mpg). For example, 30 US mpg is about 7.8 L/100 km.
A UK (imperial) gallon is about 20% larger than a US gallon, so the same car shows a higher mpg figure in the UK.
Use highway economy for long motorway trips, and combined for mixed or city driving. Your car's trip computer is best.
Yes. Add tolls and parking in the extra costs field, and they're included in the total and the per-person share.
Not directly, because it's built for liquid fuel. For an EV, use the electricity bill estimator with your charging kWh and rate.
