Need a proper code instead of any "IF" formula. When I write something in any cell in the range C8:C17, the default value 1 should be equal to the same cell in the range F8:F17. Which can be changed. And when C8:C17 is empty then F8:F17 should also be empty.

Please don't do the constant Select and ActiveCell : you might replace:

Range("G20").Select
    ActiveCell.FormulaR1C1 = "=IF(RC[-2]="""","""",5%)"

by:

Range("G20").FormulaR1C1 = "=IF(RC[-2]="""","""",5%)"

And, instead of using RC , you might do the following:

Range("G20").Formula = "=IF(Offset(-2;0)="""","""",5%)"

In top of this, you can use the whole range of F8:F17 :

Range("F8:F17").Formula = "IF(Offset(-3;0)>0,1,"""")"

This is already a big decrease of obsolete code.
