What is the Gross to Net formula?

The Gross to Net formula is used to calculate the net (pre-tax) amount if the user enters a gross amount (total expense amount, including taxes) for an expense. A Gross to Net formula should be defined for each expense code to which taxes apply.

If a user enters the net amount of an expense, Polaris will use the tax code formula associated with the expense code to calculate the gross amount of the expense.

Parentheses are used to indicate that the 10 dollars should be subtracted from the gross amount before the 6% sales tax is deducted.


Should we include a currency symbol in formulas?

No, don’t include a currency symbol. The net amount will display in the currency used for the expense.
