formula to sum accross multiple columns?

[Todd6262]

Hi, I am making a new spreadsheet, it does a simple calculation across multiple rows and sums them (F5*$E$5)+(F6*$E$6) and the numbers are totaled in sections and summed = +F32+F25+F14 (as many as 50 cells are summed). My spreadsheet works but I am hoping I can learn a better way to do this? I attached a sample of the spreadsheet I am working on.


Thank you so much.

Instead of this in F14:

=(F7*$E$7)+(F8*$E$8)+(F9*$E$9)+(F10*$E$10)+(F11*$E$11)+(F12*$E$12)+(F13*$E$13)

you could use:

=SUMPRODUCT((F7:F13)*($E$7:$E$13))

which can then be copied across that row. Similar formulae could be used for other sections, though the ranges will have to change as appropriate.

In terms of adding the sections together, you can put the word "Subtotal" or something similar in column A on the rows where these occur, and then you can use this:

=SUMIF($A:$A,"Subtotal",F:F)

and again, this can be copied across.

Hope this helps.
