Thanks Rodel, Rafael,

 

I am looking for a formula to populate the below table ie when I pull the fosrula from D3 to H3 it automatially gives the % complete based on the dates in D2 to H2.

 

So the Duration based progress % (C3-B3+1) and the % changes based on D2 to H2.

Any thing on that ?

Any such formula that misses to consider CPM calendars (work hours, iregular work days and resource availability ...) will be wrong and misleading.

Hi Jithin,

the simple formula is = (Date - Start + 1) / (Finish - Start + 1) 

Say Column A= Start, Column B = Finish, Column C = Date ... and so on, then Row 1 & Row 2 

=(C$1-$A$2+1)/($B$2-$A$2+1)

Note: Assumption - date does not have time entry that is why it needs +1. If time is included on the entry (ex: 8:00 AM to 5:00 PM) therefore + 1 is not required)
