Business RegistersVehicle logbook
Fuel, kilometres and spending for each vehicle, with kilometres per litre and cost per kilometre.
What it is for
Fuel and repairs are the largest costs of a vehicle, and most owners do not know the real cost of a kilometre. The logbook works out the kilometres since the last entry, the mileage and the cost per kilometre.. It is built for a car, a taxi, a delivery bike or a few trucks.
How to use it
- Add a row whenever you fill fuel: vehicle, date, odometer reading, litres and cost.
- Add rows for other spending, such as service, tolls or repairs, with the odometer reading.
- The table shows the kilometres since the last entry and the km per litre of each fill.
- The summary shows the total spend and the cost per kilometre for each vehicle.
