It would be nice pivot table adopt new calculation column. I need to be able to enter formulas out of the pivot table tesult. For example, I need to kno the percentage of two columns that are on my pivot table, when information refresh I need to redo my formula and add or remove source as the pivot table grow or shrink. I am looking for more calculation options on pivotT

Try using a Calculated Field. You can find it in the Calculation group in the Analyze tab when you have your cursor in the PivotTable.
