Making a sentence represent a percentage

[Tantara]

I have a cell with the value 125% in it, however I need to make the cell display the words "INCREASE BY 25%".

Example:
If cell A1 = 100, from a pull down menu in cell A2, I want the user to be able to select "INCREASE BY 25%". Having selected "INCREASE BY 25%", the value of cell A1 then needs to change from 100 to 125.

Sorry if this is basic stuff, but Google is letting me down with this one so I've turned to here for guidance.

It will take VBA to do that in the same cell (in this case cell A1)
However, if you can use a different cell for the result you can use a formula. You didn't mention if there would be Decrease by choices though.

Excel 2010
	A	B
1	100	125
2	Increase by 25%
Sheet1

Cell Formulas
Range	Formula
B1	=A1*(1+(MID(A2,12,50)))

Put your list in A2.
As mentioned by Scott Huish, only VBA could overwrite a cell with a value.
So here it is:right click sheet name, click view code and paste

Private Sub Worksheet_Change(ByVal Target As Range)
  If (Target.Column = 1 And Target.Row = 2 And Target.Value = "INCREASE BY 25%") Then
    Range("A1").Value = Range("A1").Value * 1.25
  End If
End Sub

... If the user is supposed to enter a second change of "INCREASE BY 25%", there wouldn't be a change.

Maybe a CASE SELECT would be better, depending on the number of choices, and some method of resetting the A2 cell (?)
