Formula to show the highest value another cell ever reached

I have cell with number A1, how create another cell (A2) with highest number of A1? For example: A1 = 10 A2 = 10, then i change A1 to 20 A2 = 20, then i change A1 = 12 but A2 still 20. It means if A1 greater than previous A1 it should be write to A2

You can absolutely do that. The number you want to save is in cell A1. Place this formula in cell A2 intentionally creating a circular reference.

=IF(A1>A2,A1,A2)

You need to enable iterative calculation in File > Options > Formulas > Enable iterative calculation.

Anytime a number in A1 is higher, it will save that number. It will ignore numbers with lower value. It even saves the number when saved and reopened.

See the example of a timestamp using a circular reference.

Place the following event macro in the worksheet code area:

Private Sub Worksheet_Calculate()
    newval = Range("A1")

    If Range("A2") = "" Then
    Else
        If newval <= Range("A2") Then Exit Sub
    End If

    Application.EnableEvents = False
        Range("A2") = newval
    Application.EnableEvents = True
End Sub

Because it is worksheet code, it is very easy to install and automatic to use:

  1. right-click the tab name near the bottom of the Excel window
  2. select View Code - this brings up a VBE window
  3. paste the stuff in and close the VBE window

If you have any concerns, first try it on a trial worksheet.

If you save the workbook, the macro will be saved with it. If you are using a version of Excel later then 2003, you must save the file as .xlsm rather than .xlsx

To remove the macro:

  1. bring up the VBE windows as above
  2. clear the code out
  3. close the VBE window

Macros must be enabled for this to work!
