Cars and Transport
Fuel economy, cost per kilometre, trip cost, distance and time, petrol or ethanol and depreciation.
The real cost of driving is not the price per litre: it is the relationship between litres, kilometres and the value the vehicle loses each year. These calculators keep consumption (kilometres per litre or litres per 100 km) separate from cost (money per kilometre and per trip), because one can improve without the other. The petrol versus ethanol comparison uses the 70% ratio as a practical reference, not a certainty for every engine.
How to use these calculators
- 1Record the distance driven and the litres filled between two full tanks to get real consumption.
- 2Enter the price per litre to turn consumption into cost per kilometre.
- 3For a trip, add tolls and parking to the fuel: they are not included by default.

Does the 70% rule for ethanol always hold?
It is an approximation. The break-even point depends on both fuel prices and on how much of each your vehicle consumes; the tool calculates with the values you enter.
Does cost per kilometre include maintenance?
Not by default. It covers fuel and, when provided, the price per litre; maintenance, insurance and depreciation are separate.
