Calculate trip fuel cost
The math, and how to lower it
Litres = distance ÷ average, and cost = litres × price. A 350 km trip in a car doing 14 km/l with fuel at 280/litre needs 25 litres → 7,000. Knowing your cost per km makes decisions easy: comparing bike vs car, whether a cheaper bazaar across town is really cheaper, or what to charge a friend for a shared ride. To improve your average: correct tyre pressure, gentle acceleration, less idling and a clean air filter — typically worth 10–20% together.
Frequently asked questions
How do I calculate fuel cost for a trip?
Distance ÷ km-per-litre × price per litre. 350 km ÷ 14 × 280 = 7,000.
How do I find my car's real average?
Full tank → reset trip meter → drive → refill; km driven ÷ litres refilled, over 2–3 tanks.
How can I reduce fuel cost per km?
Tyre pressure, smooth driving, less idling, timely service — commonly 10–20% savings.
