Fuel consumed, total cost and cost per person.
What it's for
Work out what a trip will cost in fuel, and how much each person pays if you split it.
Before you start
Know the distance in kilometres, how much fuel your vehicle uses, and today's pump price per litre. A fuel use you measured yourself is better than the brochure figure, which is usually optimistic.
Enter the distance
Type the one-way distance in Distance km, in digits only.
Enter fuel use and its unit
Type your vehicle's fuel use in Efficiency, then pick its unit in Measured in: km/L — higher is better or L/100km — lower is better. The line under the box shows your figure the other way round, as a check.
Enter the pump price
Type the price of one litre in Price per litre.
Set round trip and sharing
Press Round trip if you are coming back the same way; it doubles the distance. In Sharing, type how many people are splitting the cost — 1 if it is just you.
Press Calculate
Press Calculate. The answer at the top already changes as you type; the button brings it back into view.
Reading the result
If it goes wrong
Distance divided by efficiency gives litres; litres times the pump price gives the cost. The per-kilometre figure is the one worth remembering, because it stays the same whatever the trip length and lets you compare journeys.
The field that matters is the efficiency unit. km/L and L/100km are reciprocals and run in opposite directions — the label under the selector always shows your figure the other way round, so a wrong unit is visible rather than silent.
Almost certainly km/L, and the difference is enormous. They are reciprocals, not two names for the same scale: 12 km/L is an ordinary car, while 12 L/100km would be a heavy pickup. Enter one where the other is meant and the answer is out by nearly half, but it still looks plausible — which is why the label under the field always tells you what your figure means the other way round.
The most reliable way is to measure it: fill the tank, note the odometer, drive normally, fill up again, and divide the kilometres travelled by the litres it took. Manufacturer figures are measured under test conditions and are usually optimistic, especially in city traffic.
No. It is fuel only. Tolls, parking and the wear a long trip puts on the car are all real costs of driving somewhere, and none of them are counted here.
The tool divides the total evenly by the number of people. Whether the driver should pay a share, given the car and the wear, is a conversation the calculator cannot have for you.
Because twice the distance uses twice the fuel. The total doubles; the rate does not. It is a useful figure precisely because it is stable — it lets you compare this trip against another one of a different length.
The same number, opposite meanings. To convert, divide into 100: 20 km/L is 5 L/100km. Never multiply.
The cost uses the unrounded consumption, so it is ₱541.67 rather than the ₱541.45 you get from rounding to 8.33 litres first. Over a round trip that rounding would be paid twice.
Important
Fuel only. Tolls, parking and vehicle wear are not counted, and real consumption varies with traffic, load and how you drive. Nothing you type here is sent to our servers — the calculation runs entirely in your browser.
