For a particular workbook I would use Event code.

Private Sub Workbook_Open()
With Application
.Calculation = xlAutomatic
End With
End Sub

Right-click on the Excel Icon left of "File" and select "View Code".

Copy/paste the above into that Thisworkbook module.

Alt + q to return to the Excel window.

Save the workbook.

Hi,

Is there any way to force a workbook to stay in manual calculate mode upon
opening? I understand that the calculation mode is at the application level
and not the workbook level and the workbook will change to auto calculate if
another workbook is already open in auto calculate mode. Is there any way
around this?

Thanks,

Adam
