I need to apply a sumproduct formula across multiple columns. See example
below:
A B C D E F
1 $50 100 120 100 140 150
2 $60 140 90 100 160 140
3 $70 100 50 60 70 80
4 $80 10 100 120 140 200

I need a simpler formula that will give me one total for the following:
sumproduct($A$1:$A$4,B1:B4)+sumproduct($A$1:$A$4,c 1:c4)+sumproduct($A$1:$A$4,d1:d4)+sumproduct($A$1: $A$4,e1:e4)+sumproduct($A$1:$A$4,f1:f4).
I have 20 columns across and don't want to add 20 individual sumproduct
formulas.

Thanks in advance!
