I noticed that there is a lot of redundancy in your Sumproduct agruments. Try
this experimentally in place of your formula. It's a bit of a wild shot since
I can't test it. Commit with Ctrl + Shift + Enter:

=SUM((MONTH(Detail!$J$2:$J$49706)=MONTH(B15))*(YEA R(Detail!$J$2:$J$49706)=YEAR(B15))*(Detail!$N$2:$N $49706=1)*(Detail!$Q$2:$Q$49706=0)*IF($B$3="All",
(Detail!$B$2:$B$49706<"All")*IF($I$3="W/ BLANKET
ORDERS",1,Detail!$L$2:$L$49706="F"),(Detail!$B$2:$ B$49706=LeadTimes!$B$3)*IF($I$3="W/ BLANKET ORDERS",1,Detail!$L$2:$L$49706="F")))

I have the following formula on one worksheet 240 times. Of course the
formula is a bit different but the length is pretty much the same. Is there
an easier way to speed up the calculating process of this worksheet? Can this
type of formual be put in VB code behind the worksheet and will that make it
compute faster? Not really sure if any of this is possible but I figured I'd
ask. Just looking to speed up the calculations.
