In situations where you need custom calculations, formula custom attributes are a powerful way to bring this to your Placker boards.
It is similar writing formulas in Excel, but in Placker you can use other fields as variables, as will be introduced in this article.
These are some examples of formulas that may be useful depending on your working context, where an equation may contain other custom attributes, and the result is the Formula custom attribute:
Cost of hours worked: Hourly rate * Effort * 60
Cost performance index: Earned Value / Actual Cost

Price in US Dollars = Price in Euros * 1.13
Profit = Incomes - Expenses
