    If the standard payment tool is not flexible enough, you may consider using standard fields and custom calculations based on them.

    1) How to perform calculation in the form.
    2) How to assign calculation value.
    3) How to pass a calculation to a payment field.

    Take a look at 'Calculated amount based on user selections and inputs' section of the next article to see it in action.
