# Carcost

This feature allows you to monitor the expenses of one or more vehicles: fuel consumption and other costs.

## :: Create the vehicles categories

Let's imagine you have 2 cars:

- open the category dialog
- create a category named 'Car'
- create a subcategory named 'Dacia Sandero'
- create a subcategory named 'Renault Twingo'

Optionally you can set the default car to be initialized into the car-cost report window from the wallet dialog.

## :: Fill some transaction with carcost data's

A carcost transaction for refuel must include in its description:

- d=xxxxxx the odometer at refuel time
- v=xx.xx the volume of fuel

Affect the category to all of your transactions for a vehicle, this includes refuel, maintenance, repair, insurance, or others.

Example refuel description data's:

- '(d=92458 v=15.41)'
- 'd=92458, v=15.41'
- 'd=92458 v=15.41'
