    Re: Calculating overall % estimate

    You need to organize your table.

    Would be this close enough?

    However, I don't get your result...

    Book1.xls

    How did you get 70/((20*40%)+(30*19%)+(20*20%))= 0.253.?

    I assume you need (), but even then result is 70/17,7=3,95480226 as in example

    Thanks for the reply, I don't know where I got the .253 from but it was on my spreadsheet before I erased the calculation, doh.

    I shall try your calc unfortunately I cannot rearrange the sheet as I have week1 to week52 and I have planned hours, actual hours and then the estimate for the percentage complete for each week.

    Yes the actual divided by planned gives me % complete but some tasks are easy compared to others and the hours do not necessarily reflect the complexity of the task. Estimating % complete is easier than adding in fudge factors.
