Simplifying/speeding up this formula
 

Is there a way to change the following formula from
=if(calculation result 0, calculate it again, "") to =if(calculation result
0, use that result, "") ?

=IF(SUMPRODUCT(('Raw Data'!$A$2:$A$30000=$C5)*1,('Raw
Data'!$B$2:$B$30000=I$1)*1)0,SUMPRODUCT(('Raw
Data'!$A$2:$A$30000=$C5)*1,('Raw Data'!$B$2:$B$30000=I$1)*1),"")

Just thinking if there is a clever way to do this, it would cut worksheet
calculation time in half...but I'm not sure how Excel calculates and stores
this data, so my assuption may be incorrect anyway...

Thanks,
Keith

Use 2 cells The first for the sumproduct the second for the if

Doh! (slaps forehead).

Interestingly, I made other minor modifications to the sheet, and I'm not
sure what I did, but the whole thing is recalculating an order of magnitude
slower than before (independent of the 2-cell solution below). Looks like I
have some more troubleshooting to do :(

Thanks!

Or you could eliminate the IF statement completely
=SUMPRODUCT(('Raw Data'!$A$2:$A$30000=$C5)*1,('Raw Data'!$B$2:$B$30000=I$1)*1)

and use a custom number format (Format/Cells/Custom) of 0;; or #,###;; to
display a blank for zero values (and negative values, but you should not get
any negatives w/this formula).

Or eliminate a few unnecessary characters,

=SUMPRODUCT(('Raw Data'!$A$2:$A$30000=$C5)*('Raw Data'!$B$2:$B$30000=I$1))

Yep, I certainly overlooked that!
