is there a simpler way to do this formula?

[Jenna]

=(F16*J16)+(F17*J17)+(F18*J18)+(F19*J19)+(F20*J20)+(F21*J21)+(F22*J22)+(F23*J23)+(F24*J24)+(F25*J25)+(F26*J26)+(F27*J27)+(F28*J28)+(F29*J29)+(F30*J30)+(F31*J31)+(F32*J32)+(F33*J33)+(F34*J34)+(F35*J35)+(F36*J36)+(F37*J37)+(F38*J38)+(F39*J39)+(F40*J40)

first day back from maternity leave and my brain is not quite in excel mode
yet! an easier way must be out there, i just can't figure it out.

=(F16*J16)+(F17*J17)+(F18*J18)+(F19*J19)+(F20*J20)+(F21*J21)+(F22*J22)+(F23*J23)+(F24*J24)+(F25*J25)+(F26*J26)+(F27*J27)+(F28*J28)+(F29*J29)+(F30*J30)+(F31*J31)+(F32*J32)+(F33*J33)+(F34*J34)+(F35*J35)+(F36*J36)+(F37*J37)+(F38*J38)+(F39*J39)+(F40*J40)

=SUMPRODUCT(F16:F40*J16:J40)

=sumproduct(f16:f40,j16:j40)

I didn't see any rows skipped in your formula, right?

=(F16*J16)+(F17*J17)+(F18*J18)+(F19*J19)+(F20*J20)+(F21*J21)+(F22*J22)+(F23*J23)+(F24*J24)+(F25*J25)+(F26*J26)+(F27*J27)+(F28*J28)+(F29*J29)+(F30*J30)+(F31*J31)+(F32*J32)+(F33*J33)+(F34*J34)+(F35*J35)+(F36*J36)+(F37*J37)+(F38*J38)+(F39*J39)+(F40*J40)

Or, the array formula (commit with CTRL+SHIFT+ENTER):

=SUM(F16:F40*J16:J40)

How about
=SUMPRODUCT(F16:F40,J16:J40)

 

[Jenna]

Much simpler!! Thank you!!

How about
=SUMPRODUCT(F16:F40,J16:J40)
