Click on Summary (1) in the navigation area to show the Additional Charges.
There, click Add Charge (2) to add a new additional charge like overhead, contingency or other markups.
You can change the description, base and percentage of your additional charge.
Base defines on which amount your charge is being calculated. Most likely you will use the built-in formula NPC to refer the Net Production Costs, but you can also refer subtotals, sums of tagged accounts or assigned producers. The same syntax applies as in budgeting.
In this example we want to have a 10% markup (1)
on net production costs of 1.23 mio € (2),
an amount of 123k €,
leading to a Grand Total of 1.353 mio € (3):
To add a fixed amount, set percentage to 100% and base to the desired amount (1)
You can also use formulas, e.g. to calculate a 2% technical insurance on all budget accounts with the tag "insuranced" (150.000), resulting in 3.000 €. (2)
