VBA Code To Calculate How Long Your Macro Takes To Run
What This VBA Code Does
There are various scenarios where you may want to calculate the time it takes for your VBA code to run. I often do this when trying to test various ways to code a procedure. I like to see which method gives me a faster run time. Below is some simple snippets you can add to the beginning and end of your VBA code to report out how long the procedure took to run.
Display Calculation In Seconds
Sub CalculateRunTime_Seconds() 'PURPOSE: Determine how many seconds it took for code to completely run 'SOURCE: www.TheSpreadsheetGuru.com/the-code-vault Dim StartTime As Double Dim SecondsElapsed As Double 'Remember time when macro starts StartTime = Timer '***************************** 'Insert Your Code Here... '***************************** 'Determine how many seconds code took to run SecondsElapsed = Round(Timer - StartTime, 2) 'Notify user in seconds MsgBox "This code ran successfully in " & SecondsElapsed & " seconds", vbInformation End Sub
Display Calculation In Minutes
Sub CalculateRunTime_Minutes() 'PURPOSE: Determine how many minutes it took for code to completely run 'SOURCE: www.TheSpreadsheetGuru.com/the-code-vault Dim StartTime As Double Dim MinutesElapsed As String 'Remember time when macro starts StartTime = Timer '***************************** 'Insert Your Code Here... '***************************** 'Determine how many seconds code took to run MinutesElapsed = Format((Timer - StartTime) / 86400, "hh:mm:ss") 'Notify user in seconds MsgBox "This code ran successfully in " & MinutesElapsed & " minutes", vbInformation End Sub
For Bottleneck Testing
If you need a very specific timing mechanism to determine bottlenecks in your code, there is a VBA function that was written by Charles Williams called the MicroTimer. To learn more about this function, you can view the code here.
