On the Resource sheet, you have the possibility to register the costs incurred related to the Resource. To do this, go to the tile "TCO" (Total Cost of Ownership) where you can add the costs incurred for this Resource:

When you click on this button, you will enter the next dialog where you can specify the details of the cost to be added:

Within this screen, you can:
- Describe the cost to be added in detail
- In the field "Cost" you can indicate what kind of cost it is. Here you can choose from a number of predefined costs.
- The field "Type" is intended to indicate whether it is an actual cost or an estimated cost that will occur in the future.
- The field "Recurrence" allows you to indicate whether it is a one-time cost or a cost that is repeated periodically.
- In the marked date fields you can enter how long the cost runs. You can use this, for example, if you want to spread a certain cost over a certain period within the lifecycle of the vehicle.
- In the field "Amount" you enter the total amount of the cost to be registered. If this is a recurring periodic cost, we expect the amount for 1 period here. Based on the duration of 1 period, the amount per day of this cost will then be calculated. For example:
- Recurrence = Monthly
- Amount = € 60.00
- Amount per day = € 2.00 (i.e. € 60.00 / 30 days in a month)
- With the checkboxes you can indicate whether the cost should be included in the calculation of the TCO of the vehicle and/or in the calculation of the internal rental price of the vehicle.
- With this button, you can add a document related to the cost (the invoice of maintenance, for example).
After costs have been registered on the Resource, the field "Actual cost per day" will be calculated by ProPlanner. This will be the amount of the total daily cost as of today. This means that this field will only take into account the costs that relate to the current date.
