Revit schedules have the ability to perform calculations on the data within
the parameters that are included in a schedule. This information then
appears as a unique column in the schedule. To create a calculated value

of the Fields Tab in the Schedule Properties dialog box. Give the value a
descriptive name so that when it is seen in the list or schedule, its purpose
will be clear. You can create a formula by including parameters in a
mathematical equation, or you can calculate a percentage.
The percentage calculation returns the percentage of a specific parameter
as it relates to the project as a whole.

shows the settings for
percentage calculation of the volume of Space objects and the resulting
column in the schedule.

When you're creating a calculated value based on a formula, it is important
to use the proper Discipline and Type settings that coincide with the result
of the equation. You will receive a warning stating that the units are
inconsistent if the result does not match. Revit is case sensitive when it
comes to typing in parameter names, so as you write your formula, it is
crucial that you type the parameter name exactly. The small button next to
the Formula field allows you to pick the parameter from a list and inserts it
