Excel: SUMPRODUCT calculating shared workload in hours with percentages


I'm gonna re-ask a question (Excel: SUMPRODUCT with percentages) that didn't get solved in another way:

I'm trying to calculate the workload/hours for each employee for certain projects. In column B you can see the responsible (100% of the workload), in C you can see which employee is taking 50% of the workload off the responsible employee. So I need the sum of all hours, while deducing of adding the 50% in case the workload is shared and giving it to the employee helping.

My current formula:

=SUMPRODUCT(($B$2:$B$6=$A7)*($C$2:$D$6<>"")*(1-$C$1:$D$1)*E2:E6)

enter image description here


Solution

  • Another option:

    =SUMPRODUCT(($A6=$B$2:$B$5)*($B$1-$C$1*(""<>$C$2:$C$5))*D$2:D$5+($A6=$C$2:$C$5)*$C$1*D$2:D$5)
