Calculate percentage complete on a project based on time elapsed

I need help to finish a schedule for projects based on time elapsed. The current formula that I am trying to use has a Datedif formula but I don't think Smartsheet supports that. Any ideas or assistance would be helpful?


=DATEDIF([Projected Start Date]@row, [Projected Finish Date]@row,[Actual Finish Date]@row)/DATEDIF([Projected Start Date]@row,[Projected Finish Date]@row,[Actual Finish Date]@row)

    Hi @Linda F 

    Hope you are fine, try to use the following formula

    =(TODAY() - Start@row) / (Finish@row - Start@row)

    Hi Bassam

    Thank you for your suggestion - =(TODAY() - [Actual Start Date]@row) / ([Actual Finish Date]@row - [Actual Start Date]@row)

    It gave me an # DIVIDE BY ZERO message. The formula is above that I used. Is it brackets that caused the error?

    Here's what worked for me:

    =NETWORKDAYS([Start Date]@row, TODAY()) / Duration
